    The role of robot-assisted surgery across gynaecology is evolving with increasing numbers of procedures being undertaken with varying degrees of complexity. While the risk of conversion is low at approximately 1 %, the reasons for conversion are variable. These range from technical issues with the robot, surgical complications such as haemorrhage and anaesthetics issues such as an inability to ventilate the patient adequately. While many conversions to open or laparoscopic approach are not due to life-threatening indications, it is important that the theatre staff are aware of the indication and can perform an emergency undocking as effectively, efficiently and safely as possible when the need arises. Unfortunately, there is a paucity of the literature available outlining such protocols. For this reason, we developed an emergency undocking protocol clearly outlining the role of each theatre staff member and the need for clear concise communication. PMID:27126584

    Full Text Available Internal mammary artery harvesting is an essential part of any coronary artery bypass operation. Totally endoscopic coronary artery bypass graft surgery has become reality in many centers as a safe and effective alternative to conventional surgery in selected patients. Internal mammary artery harvesting is the initial part of the procedure and should be performed equally safely if one wants to achieve excellence in patency rates for the bypass. We here describe the technique for mammary harvesting with the Da Vinci Si robotic system.

    Yates, David R; Vaessen, Christophe; Roupret, Morgan

    2011-12-01

    What's known on the subject? and What does the study add? Numerous urological procedures can now be performed with robotic assistance. Though not definitely proven to be superior to conventional laparoscopy or traditional open surgery in the setting of a randomised trial, in experienced centres robot-assisted surgery allows for excellent surgical outcomes and is a valuable tool to augment modern surgical practice. Our review highlights the depth of history that underpins the robotic surgical platform we utilise today, whilst also detailing the current place of robot-assisted surgery in urology in 2011. The evolution of robots in general and as platforms to augment surgical practice is an intriguing story that spans cultures, continents and centuries. A timeline from Yan Shi (1023-957 bc), Archytas of Tarentum (400 bc), Aristotle (322 bc), Heron of Alexandria (10-70 ad), Leonardo da Vinci (1495), the Industrial Revolution (1790), 'telepresence' (1950) and to the da Vinci(®) Surgical System (1999), shows the incredible depth of history and development that underpins the modern surgical robot we use to treat our patients. Robot-assisted surgery is now well-established in Urology and although not currently regarded as a 'gold standard' approach for any urological procedure, it is being increasingly used for index operations of the prostate, kidney and bladder. We perceive that robotic evolution will continue infinitely, securing the place of robots in the history of Urological surgery. Herein, we detail the history of robots in general, in surgery and in Urology, highlighting the current place of robot-assisted surgery in radical prostatectomy, partial nephrectomy, pyeloplasty and radical cystectomy.

    2015-01-01

    Minimally invasive surgery, specifically robotic surgery, became a common technique used by gynecological surgeons over the last decade. The realization of the first human uterine transplantation commenced new perspectives in the treatment of uterine agenesia or infertility in women with history of hysterectomy at a young age. Robot-assisted technique may enhance the safety of the procedure by facilitating the microvascular anastomosis, vaginal anastomosis, and ligaments' fixation. This study proposes the formation of a multicenter collaboration group to organize a protocol with the aim to clarify the possible role of robotic surgery in uterine transplantation. PMID:26401113

    Full Text Available A subida de Urraca I (1109-1126 ao trono do reino de Leão e Castela como sucessora de Afonso VI (1072-1109 representou, como atestam vários testemunhos escritos, um acontecimento problemático para os seus contemporâneos. Consoante a posição que assumem perante este facto, os textos historiográficos peninsulares não deixaram de fornecer argumentos e justificações que favoreciam ou que, pelo contrário, atacavam o papel da filha de Afonso VI. Partindo da análise do catálogo das mulheres de Afonso VI em dois desses textos -O Chronicon Regum Legionensium e o Liber Regum Villarensis-, este artigo procura problematizar não apenas o lugar de Urraca no quadro genealógico das mulheres e da descendência de Afonso VI, mas também avaliar de que modo estas relações genealógicas são apresentadas por cada um destes textos, para legitimar ou denegrir a rainha de Leão e Castela e, através dela, a dinastia a que esta pertence.Comme on le constate à travers plusieurs témoignages écrits, l’accession au trône de León et Castille d’Urraque (1109-1126, succédantà Alphonse VI (1072-1109, fut perçue par ses contemporains comme un fait de nature problématique.

À partir de l'analyse de la liste des femmes d’Alphonse VI dans le Chronicon regum Legionensium de Pélage d’Oviedo et du Liber regum Villarensis, cet article s’intéresse non seulement à la place d’Urraque dans la généalogie des femmes et de la descendance d’Alphonse VI mais tente aussi de montrer comment ces relations généalogiques sont présentées dans chacun de ces textes afin de légitimer ou discréditer la reine de Léon et Castille et, à travers elle, sa propre dynastie.

  11. Study on DC welding parameters of Al-alloy shaping based on arc-welding robot

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The Al-alloy arc-welding shaping system based on arc-welding robot is established, and the Al-alloy shaping manufacture is realized with the DC (direct current) gas metal arc welding (GMAW). The research indicates that the metal transfer type of DC GMAW, heat input and the initial temperature of the workpiece greatly affect the Al-alloy shaping based on arc welding robot. On the penetration, the weld width and the reinforcement, the influence of welding parameters is analyzed by generalized regression neural network (GRNN) fitting.

  12. Application of da Vinci® Robot in simple or radical hysterectomy: Tips and tricks

    Science.gov (United States)

    Iavazzo, Christos; Gkegkes, Ioannis D.

    2016-01-01

    The first robotic simple hysterectomy was performed more than 10 years ago. These days, robotic-assisted hysterectomy is accepted as an alternative surgical approach and is applied both in benign and malignant surgical entities. The two important points that should be taken into account to optimize postoperative outcomes in the early period of a surgeon’s training are how to achieve optimal oncological and functional results. Overcoming any technical challenge, as with any innovative surgical method, leads to an improved surgical operation timewise as well as for patients’ safety. The standardization of the technique and recognition of critical anatomical landmarks are essential for optimal oncological and clinical outcomes on both simple and radical robotic-assisted hysterectomy. Based on our experience, our intention is to present user-friendly tips and tricks to optimize the application of a da Vinci® robot in simple or radical hysterectomies. PMID:27403078

    2009-01-01

    This technical report is designed to serve as a citable reference for the original prioritized object list that the Healthcare Robotics Lab at Georgia Tech released on its website in September of 2008. It is also expected to serve as the primary citable reference for the research associated with this list until the publication of a detailed, peer-reviewed paper. The original prioritized list of object classes resulted from a needs assessment involving 8 motor-impaired patients with amyotrophic lateral sclerosis (ALS) and targeted, in-person interviews of 15 motor-impaired ALS patients. All of these participants were drawn from the Emory ALS Center. The prioritized object list consists of 43 object classes ranked by how important the participants considered each class to be for retrieval by an assistive robot. We intend for this list to be used by researchers to inform the design and benchmarking of robotic systems, especially research related to autonomous mobile manipulation.

  16. Understanding the adoption dynamics of medical innovations: affordances of the da Vinci robot in the Netherlands.

    Abrishami, Payam; Boer, Albert; Horstman, Klasien

    2014-09-01

    This study explored the rather rapid adoption of a new surgical device - the da Vinci robot - in the Netherlands despite the high costs and its controversial clinical benefits. We used the concept 'affordances' as a conceptual-analytic tool to refer to the perceived promises, symbolic meanings, and utility values of an innovation constructed in the wider social context of use. This concept helps us empirically understand robot adoption. Data from 28 in-depth interviews with diverse purposively-sampled stakeholders, and from medical literature, policy documents, Health Technology Assessment reports, congress websites and patients' weblogs/forums between April 2009 and February 2014 were systematically analysed from the perspective of affordances. We distinguished five interrelated affordances of the robot that accounted for shaping and fulfilling its rapid adoption: 'characteristics-related' affordances such as smart nomenclature and novelty, symbolising high-tech clinical excellence; 'research-related' affordances offering medical-technical scientific excellence; 'entrepreneurship-related' affordances for performing better-than-the-competition; 'policy-related' affordances indicating the robot's liberalised provision and its reduced financial risks; and 'communication-related' affordances of the robot in shaping patients' choices and the public's expectations by resonating promising discourses while pushing uncertainties into the background. These affordances make the take-up and use of the da Vinci robot sound perfectly rational and inevitable. This Dutch case study demonstrates the fruitfulness of the affordances approach to empirically capturing the contextual dynamics of technology adoption in health care: exploring in-depth actors' interaction with the technology while considering the interpretative spaces created in situations of use. This approach can best elicit real-life value of innovations, values as defined through the eyes of (potential) users. PMID

  17. Load evaluation of the da Vinci surgical system for transoral robotic surgery.

    2015-12-01

    Transoral robotic surgery, performed with the da Vinci surgical system (da Vinci), is a surgical approach for benign and malignant lesions of the oral cavity and laryngopharynx. It provides several unique advantages, which include a 3-dimensional magnified view and ability to see and work around curves or angles. However, the current da Vinci surgical system does not provide haptic feedback. This is problematic because the potential risks specific to the transoral use of the da Vinci include tooth injury, mucosal laceration, ocular injury and mandibular fracture. To assess the potential for intraoperative injuries, we measured the load of the endoscope and the instrument of the da Vinci Si surgical system. We pressed the endoscope and instrument of the da Vinci Si against Load cell six times each and measured the dynamic load and the time-to-maximum load. We also struck the da Vinci Si endoscope and instrument against the Load cell six times each and measured the impact load. The maximum dynamic load was 7.27 ± 1.31 kg for the endoscope and 1.90 ± 0.72 for the instrument. The corresponding time-to-maximum loads were 1.72 ± 0.22 and 1.29 ± 0.34 s, but the impact loads were significantly lower than the dynamic load. It remains possible that a major load is exerted on adjacent structures by continuous contact with the endoscope and instrument of da Vinci Si. However, there is a minor delay in reaching the maximum load. Careful monitoring by an on-site assistant may, therefore, help prevent contiguous injury.

    2015-01-28

    Tough Al-alginate/poly(N-isopropylacrylamide) (PNIPAM) hydrogel has been synthesized by introducing an interpenetrating network with hybrid physically cross-linked alginate and chemically cross-linked PNIPAM. Varying the concentration of AlCl3 regulates the mechanical properties of the tough hydrogel and tunes its lower critical solution temperature (LCST) as well. The tough Al-alginate/PNIPAM exhibits 6.3 ± 0.3 MPa of compressive stress and 9.95 of uniaxial stretch. Tunability of LCST is also achieved in a wide range within 22.5-32 °C. A bending beam actuator and a four-arm gripper made of bilayer (Na-alginate/PNIPAM)/(Al-alginate/PNIPAM) hydrogel as prototype of all-hydrogel soft robotics are demonstrated. A finite element (FE) simulation model is developed to simulate the deformation of the soft robotics. The FE simulation not only reproduces the deformation process of performed experiments but also predicts more complicated devices that can be explored in the future. This work broadens the application of temperature-responsive PNIPAM-based hydrogels.

    2015-02-01

    Using a pretest-posttest design, Srinivasan, et al. (2013 ) found that a period of interaction between children and an Isobot humanoid robot improved performance on standardized measures of imitation, planning, and execution of motor behaviors. The authors conducted their study with 15 typically developing children (9 boys, 6 girls) and 1 boy with autism. All participants were between the ages of 4 and 7 years. While considerations of gender expectations, norms, and appearance are now considered critical to social interactions between humans and robots by most researchers in the field of human-robot interactions, Srinivasan et al. did not consider these effects. This paper proposes that gender could have significant effects on the results of future work conducted in this area.

    The increased distance between surgeon and surgical field is a significant problem in laparoscopic surgery. Robotic surgery, although providing advantages for the operator, increases this gap by completely removing force feedback. Enhancement with visual tools can therefore be beneficial. The goal of this preliminary work was to create a custom plugin for OsiriX to display volume-rendered images in the da Vinci surgeon's console. The TilePro multi-input display made the generated stereoscopic pairs appear to have depth. Tumor position, vascular supply, spatial location, and relationship between organs appear directly within the surgeon's field of view. This study presents a case of totally robotic right colectomy for cancer using this new technology. Sight diversion was no longer necessary. Depth perception was subjectively perceived as profitable. Total immersion in the operative field helped compensate for the lack of tactile feedback specific to robotic intervention. This innovative tool is a step forward toward augmented-reality robot-assisted surgery. PMID:22549904

    Inorganic light-emitting diodes and photodetectors represent important, established technologies for solid-state lighting, digital imaging and many other applications. Eliminating mechanical and geometrical design constraints imposed by the supporting semiconductor wafers can enable alternative uses in areas such as biomedicine and robotics. Here we describe systems that consist of arrays of interconnected, ultrathin inorganic light-emitting diodes and photodetectors configured in mechanically optimized layouts on unusual substrates. Light-emitting sutures, implantable sheets and illuminated plasmonic crystals that are compatible with complete immersion in biofluids illustrate the suitability of these technologies for use in biomedicine. Waterproof optical-proximity-sensor tapes capable of conformal integration on curved surfaces of gloves and thin, refractive-index monitors wrapped on tubing for intravenous delivery systems demonstrate possibilities in robotics and clinical medicine. These and related systems may create important, unconventional opportunities for optoelectronic devices.

Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

    Full Text Available Herbicides are widely used in soybean for weed control, and the selection pressure attributed to the repeated use of herbicides with similar modes of action on the same site has caused selection for resistant biotypes within and among previously susceptible species, such as Euphorbia heterophylla L., in relation to ALS enzyme inhibitors, in the states of Paraná, Rio Grande do Sul, and São Paulo, Brazil. Seeds of E. heterophylla were collected to examine possible new cases of resistant populations and to test alternative herbicide treatments to manage these populations, in the Caarapó region, State of Mato Grosso do Sul, Brazil, in areas where plants of this species have survived continuous herbicide applications. The experiment was carried out under greenhouse conditions, where biotypes with a history of suspected resistance were compared with a known susceptible biotype. Several post-emergence herbicides were sprayed at zero, one, two, four, and eight times the recommended field application rates. Twenty days after application, plants were harvested, and control percentage and fresh weight were determined to establish dose-response curves, in the aim to obtain the resistance factor using CD50 and RD50 data. The chlorimuron-ethyl resistance factor values for the control percentage and fresh weight parameters were higher than 16.5 and 16.9, respectively, while imazethapyr showed resistance factors higher than 25.0 and 23.5, respectively. The resistant biotype showed different resistance levels to chlorimuron-ethyl and imazethapyr, showing cross-resistance to the sulfonylurea and imidazolinone groups. Nevertheless, this biotype was effectively controlled by fomesafen (250 g ha-1, lactofen (120 g ha-1, flumiclorac-pentyl (40 g ha-1, glufosinate-ammonium (150 g ha-1, and glyphosate (360 g ha-1.Os herbicidas constituem a principal medida de controle de plantas daninhas na cultura da soja, mas através da pressão de seleção, o uso contínuo e

Essa perspectiva exercita uma espécie de movimento turbilhonar que não aceita a representação do mero instalado, mas marca o corpo na imanência do acontecimento diferencial que se caracteriza pela aventura da sua existência. Como um corpo que sente e que luta e labuta no eterno jogo de criação. Assim, o grande acontecimento se configura pelo movimento e o aprendizado se faz na sua própria instalação de si, exercendo a multiplicidade, a inocência da criação. Sem determinações ou enclausuramentos. Essa formação pensa a transformação em toda sua potência de vida.

Die herkömmliche Struktur der chirurgischen Ausbildungs- und Lehrtätigkeiten ist für die Vermittlung der Roboterchirurgie nicht besonders gut geeignet. Materialien und Methoden: Erfahrene Laparoskopie-Chirurgen können sich in speziellen Schulungskursen die Feinheiten der Roboterchirurgie relativ leicht aneignen. Dies gilt nicht für relativ unerfahrene chirurgische Praktikanten, wenngleich den Ausbildungsprogrammen auf jeden Fall die Verantwortung zukommt, auch das Fachgebiet der Robotertechnik zu lehren. Die Richtlinien des Amerikanischen Urologenverbands und des Accreditation Council on Graduate Medical Education werden geprüft und bei den Versuchen zur Bewältigung dieser Probleme herangezogen. Die einzelnen Verfahrensschritte, insbesondere die Prostatektomie, werden aus der Lehrendenperspektive betrachtet. Ergebnisse: Ein Curriculum der Roboterchirurgie kann in das Gesamtausbildungsprogramm erfolgreich integriert werden. Die Konsolenzeit wird auf die Erfahrung als Assistent am Krankenbett abgestimmt, ebenso wie die Entwicklung grundlegender laparoskopischer Fertigkeiten und eines Verständnisses der optischen Anatomie. Die Kompetenz als Klinikassistent ist erforderlich, bevor weitere Fortschritte zu den höheren Stufen der Konsolenbedienung erwogen werden können. Die chirurgischen Schritte werden in logische Fortschritte mit Fertigkeitseinheiten in verschiedenen Segmenten unterteilt, ehe eine Reihe von Segmenten zusammengesetzt werden kann, um signifikante Abschnitte der eigentlichen Operation zu ergeben.

    2016-07-01

    Santello et al. [1] review an impressive amount of work on the control of biological and artificial hands that demonstrates how the concept of synergies can lead to a successful integration of robotics and neuroscience. Is it possible to generalize the same approach to the control of biological and artificial limbs and bodies beyond the hand? The human hand synergies that appear most relevant for robotic hands are those defined at the kinematic level, i.e. postural synergies [2]. Postural synergies capture the geometric relations among the many joints of the hand and allow for a low dimensional characterization and synthesis of the static hand postures involved in grasping and manipulating a large set of objects. However, many other complex motor skills such as walking, reaching, throwing, and catching require controlling multi-articular time-varying trajectories rather than static postures. Dynamic control of biological and artificial limbs and bodies, especially when geometric and inertial parameters are uncertain and the joints are compliant, poses great challenges. What kind of synergies might simplify the dynamic control of motor skills involving upper and lower limbs as well as the whole body?

    Full Text Available Por mais que o avanço da ciência e da tecnologia esteja na raiz de vitórias decisivas na luta por melhores condições sociais, é impossível não reconhecer a ameaça crescente que o conhecimento e suas aplicações práticas representam não só para as sociedades humanas, mas para a vida em seu conjunto. A capacidade humana de intervir sobre a natureza é hoje muito maior que a possibilidade de prever com um mínimo de segurança os resultados dessa intervenção. Para Hans Jonas esse contraste só pode ser abordado com base numa exigência ética que ele sintetiza no Princípio Responsabilidade, e que se apoia na heurística do medo. Baseado numa abordagem crítica do dualismo que marca a cultura ocidental e separa matéria e espírito, corpo e mente, natureza e sociedade, Hans Jonas rejeita a ideia de que uma organização social voltada explicitamente à satisfação das necessidades humanas (e não ao lucro suprima a exigência de uma reflexão específica sobre as ameaças vindas da expansão autônoma da ciência e da tecnologia. Este trabalho, além de expor as bases do dualismo estudado por Jonas, procura mostrar que suas preocupações não são contempladas pela eventual adoção do princípio da precaução e mostra, ao final, duas áreas (biologia e geoengenharia em que a aplicação de sua filosofia da tecnologia pode ser especialmente relevante.

    Full Text Available O ativismo político feminino popular tem sido analisado a partir da matriz explicativa da “maternidade militante”, originada na década de 80. Essa matriz associa o engajamento dessas mulheres à reprodução dos seus atributos de mães no universo da política. Contemporaneamente, a experiência de ativismo político dessa parcela da população feminina desafia essa matriz explicativa, apontando novas possibilidades compreensivas para esse fenômeno. Por meio de uma pesquisa etnográfica realizada na cidade de Recife-PE entre ativistas dos direitos das mulheres, de diferentes estratos sociais, este texto busca demonstrar essas novas possibilidades.PALAVRAS-CHAVES: ativismo político, mulheres, maternidade, camadas urbanas de baixa renda, feminismoABSTRACT: The popular female political activism has been analyzed by the “militant motherhood” model, created in the 80’s. This model links these women’s political commitment to the reproduction of their attributes as mothers in the political universe. In more contemporary times, the political activism experience of women from lower classes challenges this model and shows new comprehensive possibilities to this phenomenon. Based on the ethnographic research done in the city of Recife/PE, among women´s rights activists from different social stratum, this text intents to demonstrate these new possibilities. KEY-WORDS: political activism, women, motherhood, urban low classes, feminism

    Full Text Available The term "robot" was coined by the Czech playright Karel Capek in 1921 in his play Rossom′s Universal Robots. The word "robot" is from the check word robota which means forced labor.The era of robots in surgery commenced in 1994 when the first AESOP (voice controlled camera holder prototype robot was used clinically in 1993 and then marketed as the first surgical robot ever in 1994 by the US FDA. Since then many robot prototypes like the Endoassist (Armstrong Healthcare Ltd., High Wycombe, Buck, UK, FIPS endoarm (Karlsruhe Research Center, Karlsruhe, Germany have been developed to add to the functions of the robot and try and increase its utility. Integrated Surgical Systems (now Intuitive Surgery, Inc. redesigned the SRI Green Telepresence Surgery system and created the daVinci Surgical System ® classified as a master-slave surgical system. It uses true 3-D visualization and EndoWrist ® . It was approved by FDA in July 2000 for general laparoscopic surgery, in November 2002 for mitral valve repair surgery. The da Vinci robot is currently being used in various fields such as urology, general surgery, gynecology, cardio-thoracic, pediatric and ENT surgery. It provides several advantages to conventional laparoscopy such as 3D vision, motion scaling, intuitive movements, visual immersion and tremor filtration. The advent of robotics has increased the use of minimally invasive surgery among laparoscopically naοve surgeons and expanded the repertoire of experienced surgeons to include more advanced and complex reconstructions.

Nella prima parte di questo articolo sono ricostruiti i diversi momenti in cui questa gerarchia è stata fondata e si è affermata stabilmente: dai contrasti epocali tra Socrate e  Platone da una parte e i Sofisti dall'altra all'affermazione della centralità della scrittura da parte di Aristotele e degli aristotelici; fino, poi, all'Illuminismo, in cui l'oralità veniva ormai identificata con l'inciviltà, la rozzezza e l'arretratezza, posizione che in qualche misura permane ancora oggi. Nella seconda parte dell'articolo si ricostruisce il graduale recupero del valore dell'oralità nell'insegnamento linguistico, attraverso un'analisi dei programmi scolastici italiani, dalla Legge Casati del 1859 ai Programmi della scuola media e di quella elementare rispettivamente del 1979 e del 1985, alle più recenti "Indicazioni Moratti e infine alle "Indicazioni Fioroni". In queste ultime si sottolinea la necessità di finalizzare l'insegnamento dell'oralità anche a scopi interculturali più ampi, prioritari nella società attuale, quali il rispetto e la promozione delle differenze linguistiche e culturali, lo sviluppo del plurilinguismo; la centralità e l'autonomia dell'apprendente.   Historically, the oral tradition has been more important than writing, both in human history (philogenesis and in individual, personal history (onthogenesis, but it has always had far less prestige. The first part of this paper surveys important moments in the formation and establishment of this hierarchy, starting from the fundamental contrast between the Sophists on the one hand, and Socrates and Plato from the other, to the centrality of Aristotle and Aristotelianism, up to the Age of Enlightenment and the identification between orality

    Full Text Available Os termos publicidade e propaganda têm sofrido, em anos recentes, de um agravamento na forma indistinta com que são utilizados. Tal fato pode ser analisado dos pontos de vista lingüístico e histórico. Do ponto de vista lingüístico, é perceptível na língua inglesa a presença de três noções que precisam ser ajustadas às duas disponíveis nas línguas latinas em geral. Do ponto de vista histórico, é possível depreender, com base em uma aproximação com as idéias de Jürgen Habermas, que tanto a publicidade de “tornar públicas ações de esfera pública” quanto a de “anunciar transações comerciais” são criações burguesas comprometidas com o racionalismo e com a modernidade, sobrevindas da noção de público e, portanto, características de seu desenvolvimento socioeconômico baseado nas liberdades individuais e no mercado. Palavras-chave: Publicidade; esfera pública; mercado. ABSTRACT The terms publicidade and propaganda have increasingly been used indistinctively in Brazil in recent years. Such fact can be analyzed from linguistic and historical points of view. From the linguistic point of view, the presence of a third concept in the English language usually needs to be adjusted to the two available ones in Latin languages. From the historical point of view, it is possible to infer over a Jürgen Habermas analysis, that both meanings of publicidade – “to make public the actions within thepublic sphere” and “to advertise commercial transactions” – are bourgeois creations implied to rationalism and modernity, in-herited from the notion of “public”. Therefore, it is characteristics of its social-economic development based on individual freedoms and market orientation. Keywords: Publicity; public sphere; market.

  12. Radiation effects in a CMOS/SOS/Al-Gate D/A converter and on-chip diagnostic transistors

    International Nuclear Information System (INIS)

    This paper presents the results obtained from total dose and transient radiation tests on a CMOS/SOS/Al-Gate D/A converter and on-chip diagnostic transistors. Samples were irradiated by cobalt-60 gamma rays under worst-case conditions, and by 10-MeV electron pulses of 50-ns and 4.4-μs duration. Devices were fabricated with three different insulators; the two discussed here are standard wet oxide and a pyrogenic oxide. Test transistors on the D/A chips made it possible to diagnose the failure modes of the converter and to evaluate some special designs. These consisted of standard edge p- and n-channel transistors, edgeless units, edgeless tetrode transistors, and an edgeless type transmission gate with a diode clamp from substrate to gate. The total dose results indicate that the pyrogenic oxide increased the failure dose of the operational amplifier portion of the converter from 103 rads (Si) to 2 x 106 rads (Si); however, the sample and hold failed after exposure to a low level of 103 rads (Si). Test devices indicated this to be due to the radiation-induced leakage current of the transmission gate which discharges the sample and hold capacitor. The diode clamp decreased the threshold voltage shifts and the leakage currents. The edgeless devices improved the device performance because of a more abrupt turn-on. Narrow-pulse test data indicated that the edgeless units produced less photocurrent than the edge units by about a factor of three to four. Converter upset levels are less than or equal to 109 rads/s due to precision requirements which make a few millivolt transients untenable

Conclusões Ao longo dos anos houve um aumento do número de crianças que viajam pelo mundo. Entretanto, essa população não está isenta de apresentar problemas de saúde durante a viagem e pode ser até mais suscetível do que a faixa etária adulta. Esses surgem a partir de uma variedade de fatores, incluindo a exposição a organismos infecciosos, o uso de certos tipos de transporte e a participação em algumas atividades, como caminhadas para altas altitudes, entre outros. Porém, quando se viaja com crianças esses fatores de risco podem ser negligenciados e uma viagem considerada segura para um adulto pode não ser uma boa opção para os infantes. A consulta pediátrica deve ser uma boa oportunidade para aprimorar as orientações preventivas no planejamento pré-viagem.

    The idea of reproducing himself with the use of a mechanical robot structure has been in man's imagination in the last 3000 years. However, the use of robots in medicine has only 30 years of history. The application of robots in surgery originates from the need of modern man to achieve two goals: the telepresence and the performance of repetitive and accurate tasks. The first "robot surgeon" used on a human patient was the PUMA 200 in 1985. In the 1990s, scientists developed the concept of "master-slave" robot, which consisted of a robot with remote manipulators controlled by a surgeon at a surgical workstation. Despite the lack of force and tactile feedback, technical advantages of robotic surgery, such as 3D vision, stable and magnified image, EndoWrist instruments, physiologic tremor filtering, and motion scaling, have been considered fundamental to overcome many of the limitations of the laparoscopic surgery. Since the approval of the da Vinci(®) robot by international agencies, American, European, and Asian surgeons have proved its factibility and safety for the performance of many different robot-assisted surgeries. Comparative studies of robotic and laparoscopic surgical procedures in general surgery have shown similar results with regard to perioperative, oncological, and functional outcomes. However, higher costs and lack of haptic feedback represent the major limitations of current robotic technology to become the standard technique of minimally invasive surgery worldwide. Therefore, the future of robotic surgery involves cost reduction, development of new platforms and technologies, creation and validation of curriculum and virtual simulators, and conduction of randomized clinical trials to determine the best applications of robotics.

In the 1990s, scientists developed the concept of "master-slave" robot, which consisted of a robot with remote manipulators controlled by a surgeon at a surgical workstation. Despite the lack of force and tactile feedback, technical advantages of robotic surgery, such as 3D vision, stable and magnified image, EndoWrist instruments, physiologic tremor filtering, and motion scaling, have been considered fundamental to overcome many of the limitations of the laparoscopic surgery. Since the approval of the da Vinci(®) robot by international agencies, American, European, and Asian surgeons have proved its factibility and safety for the performance of many different robot-assisted surgeries. Comparative studies of robotic and laparoscopic surgical procedures in general surgery have shown similar results with regard to perioperative, oncological, and functional outcomes. However, higher costs and lack of haptic feedback represent the major limitations of current robotic technology to become the standard technique of minimally invasive surgery worldwide. Therefore, the future of robotic surgery involves cost reduction, development of new platforms and technologies, creation and validation of curriculum and virtual simulators, and conduction of randomized clinical trials to determine the best applications of robotics.

    FDA approved Da Vinci Surgical System in 2005 for gynecological surgery. It has been rapidly adopted and it has already assumed an important position at various centers where this is available. It comprises of three components: A surgeon's console, a patient-side cart with four robotic arms and a high-definition three-dimensional (3D) vision system. In this review we have discussed various robotic-assisted laparoscopic benign gynecological procedures like myomectomy, hysterectomy, endometriosis, tubal anastomosis and sacrocolpopexy. A PubMed search was done and relevant published studies were reviewed. Surgeries that can have future applications are also mentioned. At present most studies do not give significant advantage over conventional laparoscopic surgery in benign gynecological disease. However robotics do give an edge in more complex surgeries. The conversion rate to open surgery is lesser with robotic assistance when compared to laparoscopy. For myomectomy surgery, Endo wrist movement of robotic instrument allows better and precise suturing than conventional straight stick laparoscopy. The robotic platform is a logical step forward to laparoscopy and if cost considerations are addressed may become popular among gynecological surgeons world over. PMID:25598600

    Full Text Available A urbanização sem planejamento ao longo da bacia do rio Jacarecica, em Maceió, AL, causa grandes impactos ambientais. A substituição de áreas vegetadas por áreas urbanizadas agrava esses impactos. No entanto, o potencial efeito dessas modificações na produção de sedimentos é desconhecido. Neste trabalho, avaliaram-se mudanças da produção de sedimentos na bacia do rio Jacarecica, no ano de 2010, em razão da alteração de parte da cobertura do solo por urbanização, por meio de modelagem matemática. Os resultados evidenciaram que o mês com maior produção produziu mais de 120 t/ha/mês, perfazendo o total de 131 t, correspondente a uma área de 24,5 km² da área total da bacia, revelando que grande parte da bacia é realmente susceptível ao processo de erosão. Este trabalho apresenta que a aplicação do modelo KINEROS2 é viável e o seu acoplamento ao SIG é de grande valia para identificação e análise das principais áreas de produção de sedimentos na bacia deste rio, podendo ser considerado ferramenta promissora para simulação da produção de sedimentos em bacias hidrográficas do nordeste brasileiro.

MÉTODOS: Estudo qualitativo com dez mães ouvintes com filhos surdos que frequentavam atendimento especializado em Centro de Estudos e Pesquisas em Reabilitação, no estado de São Paulo, há pelo menos dois anos. Realizou-se entrevista semiestruturada com as mães e foi feita análise da fala das participantes, buscando compreender o sentido que as mães deram à sua comunicação. RESULTADOS: Apesar do diagnóstico de seis crianças ter sido feito antes de um ano de idade e, considerando-se os múltiplos sentimentos das mães frente à surdez de seus filhos, observou-se que, em alguns casos, o diagnóstico poderia ter ocorrido antes se a fala das mães fosse valorizada. Percebeu-se dificuldade de "escuta" dos profissionais da saúde em relação às dúvidas, queixas e questionamentos das mães. Constatou-se que, em alguns casos, mesmo quando ocorreu a triagem auditiva neonatal ou o diagnóstico oportuno, retardou-se o atendimento à criança porque não foram feitos encaminhamentos adequados para locais que trabalham na área da surdez. No momento do diagnóstico, a forma como foi comunicada a surdez à família necessitaria levar em consideração as condições sociais, culturais e emocionais das mães. CONCLUSÕES: Ressalta-se a importância da qualificação e atenção dos profissionais de saúde, para possibilitar o diagnóstico precoce, o apoio aos pais e o encaminhamento e seguimento adequados para os casos de surdez.OBJETIVO: Investigar la vivencia de las madres entre la sospecha, el diagnóstico de sordera y el encaminamiento para habilitación, así como la percepción de ellas respecto a la forma como se dio y explicó el diagnóstico.

    Full Text Available OBJETIVO: Verificar, do ponto de vista clínico e morfológico, o efeito da chalcona na conjuntivite alérgica induzida por ovalbumina em cobaias. MÉTODOS: Utilizaram-se 54 cobaias, albinos, machos pesando aproximadamente 400 g. Os animais foram sensibilizados por injeção intraperitoneal de ovalbumina suspensa em solução adjuvante completa de Freund. Posteriormente, a conjuntivite alérgica foi induzida por instilação de ovalbumina no saco conjuntival do olho direito. Os animais foram distribuídos em 3 grupos, conforme o tratamento proposto: chalcona, corticóide e salina. A avaliação clínica foi realizada com 5, 10 e 40 min, 7 e 24 h da indução e diariamente até o dia 7 da indução. A avaliação morfológica consistiu em avaliar edema, necrose, vascularização e exocitose nos dias 1, 3 e 7 da indução. RESULTADOS: Em todos os grupos a resposta inflamatória foi mais intensa 24 h após a indução. No grupo chalcona evidenciou-se menos sinais inflamatórios que no grupo salina. O grupo corticóide apresentou menos sinais inflamatórios quando comparados aos grupos chalcona e controle. À análise morfológica evidenciou-se que os grupos chalcona e corticóide apresentaram efeitos terapêuticos semelhantes. CONCLUSÃO: A chalcona teve efeito terapêutico na conjuntivite alérgica induzida por ovalbumina.

    Full Text Available DWI é uma técnica totalmente não invasiva que tem sido utilizada com sucesso por muitos anos em imagens do cérebro e recentemente incluída como parte da avaliação de outros sistemas, por exemplo, no abdome e pelve e na cabeça e pescoço. Apesar de a DWI e a medida dos valores de ADC serem capazes de fornecer informações de tipos histológicos específicos de tumores, a maioria dos centros de imagem ainda não os adotaram como parte da rotina na avaliação da cabeça e pescoço. A medida de ADC demonstrou ser útil para discriminar tipos específicos de tumores histológicos, especialmente para diferenciar lesões benignas sólidas de massas malignas, importante na avaliação de linfonodos cervicais, principalmente para diferenciar processos nodais benignos de malignos, para diferenciar as alterações pós-radioterapia de tumor residual e ter uso potencial para predizer sucesso terapêutico. Além disso, DWI/ADC parece ser um método mais seguro e mais acessível, considerando a ausência de radiação ionizante e ao maior custo do FDG-PET na localização de tumores e diferenciar massas benignas de malignas. Com todas essas vantagens e potencialidades, DWI/ADC certamente fará parte da rotina na avaliação por imagem da cabeça e pescoço.

    PURPOSE OF REVIEW: Robot-assisted laparoscopic surgery in urology has gained immense popularity with the daVinci system, but a lot of research teams are working on new robots. The purpose of this study is to review current urologic robots and present future development directions. RECENT FINDINGS: Future systems are expected to advance in two directions: improvements of remote manipulation robots and developments of image-guided robots. SUMMARY: The final goal of robots is to allow safer and more homogeneous outcomes with less variability of surgeon performance, as well as new tools to perform tasks on the basis of medical transcutaneous imaging, in a less invasive way, at lower costs. It is expected that improvements for a remote system could be augmented in reality, with haptic feedback, size reduction, and development of new tools for natural orifice translumenal endoscopic surgery.

  13. Learning in robotic manipulation: The role of dimensionality reduction in policy search methods. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    2016-07-01

    A question that often arises, among researchers working on artificial hands and robotic manipulation, concerns the real meaning of synergies. Namely, are they a realistic representation of the central nervous system control of manipulation activities at different levels and of the sensory-motor manipulation apparatus of the human being, or do they constitute just a theoretical framework exploiting analytical methods to simplify the representation of grasping and manipulation activities? Apparently, this is not a simple question to answer and, in this regard, many minds from the field of neuroscience and robotics are addressing the issue [1]. The interest of robotics is definitely oriented towards the adoption of synergies to tackle the control problem of devices with high number of degrees of freedom (DoFs) which are required to achieve motor and learning skills comparable to those of humans. The synergy concept is useful for innovative underactuated design of anthropomorphic hands [2], while the resulting dimensionality reduction simplifies the control of biomedical devices such as myoelectric hand prostheses [3]. Synergies might also be useful in conjunction with the learning process [4]. This aspect is less explored since few works on synergy-based learning have been realized in robotics. In learning new tasks through trial-and-error, physical interaction is important. On the other hand, advanced mechanical designs such as tendon-driven actuation, underactuated compliant mechanisms and hyper-redundant/continuum robots might exhibit enhanced capabilities of adapting to changing environments and learning from exploration. In particular, high DoFs and compliance increase the complexity of modelling and control of these devices. An analytical approach to manipulation planning requires a precise model of the object, an accurate description of the task, and an evaluation of the object affordance, which all make the process rather time consuming.

    Objective To summarize the experience of minimally invasive robotic caronary bypass on beating heart using da Vinci S in China. Methods Fifty-six patients underwent selected robotic coronary bypass on beating heart from April 2007 to December 2008. All the patients had history of angina and the coronary arteriography showed severe stenosis in the left anterior descending artery (LAD), of which 10 cases had right coronary artery or left circumflex coronary (LCX) stenosis. The age was 33 to 74 years old, with a mean of (55.8±9. 4) years old. The weight was (71.4 ± 13.2) kg, All the patients had good lung function and had no medical history of pleurisy and thoracic surgery. CT scan of double internal thoracic artery (ITA) was routinely checked preoperatively. The procedures included : (1) The robotically assisted endoscopic atranmatic coronary artery bypass surgery. The approach was via a small left anterior thoracotomy (6 to 8 cm) after robotic ITA was taken down. The ITA was manually anastomosed to the LAD or LCX on beating heart. (2) Totally endoscopic coronary bypass graft on beating heart. After ITA harvesting, the endostabilizer was inserted via the fourth pert in the xiphoid area under endoscopic vision. The left ITA to the LAD grafting was done using U-clips on beating heart in a totally endoscopic manner using da Vinci S system through 4 ports. For all patients the ITA flow was checked by the Doppler flowmeter after anastomosis was completed. After the surgery was completed, the thoracic port was checked carefully to avoid bleeding, The operating procedures and a variety of clinical parameters were recorded and analyzed. (3) Stent placement after robotic surgery in a hybrid manner. The graft pateney rate was evaluated by CT or orteriography. Results All patients successfully accepted robotic minimally invasive coronary bypass on the beating heart using da Vinci S surgical system without complications. The mean graft flow was (23.2 ± 16. 7) mL/min. And

  1. Comparison of H/Al stoichiometry of mineral and organic soils in Brazil Comparação da estequiometria H/Al em solos minerais e orgânicos brasileiros

    Directory of Open Access Journals (Sweden)

    2009-08-01

    Full Text Available Exchangeable Al has been used as a criterion for the calculation of lime requirement in several Brazilian States. However, the laboratory method with extraction by a 1 mol L-1 KCl solution followed by indirect alkaline titration is not accurate for some Brazilian soils, mainly in the case of soils with high organic matter content. The objective of this study was therefore to evaluate the stoichiometry of H+/Al3+ in KCl soil extracts. The results suggested that organically complexed Al is the main contributor to exchangeable acidity in soils enriched with organic matter. Liming recommendations for organic soils based exclusively on exchangeable Al determined by the NaOH titration method should therefore be revised.A determinação de alumínio trocável é utilizada como critério para cálculo de calagem em vários estados brasileiros. Contudo, a determinação indireta pela titulação com NaOH, após extração com solução de KCl 1 mol L-1, pode não ser adequada para certos tipos de solos brasileiros, notadamente aqueles que apresentem altos teores de carbono orgânico. Dessa forma, o principal objetivo deste trabalho foi avaliar a estequiometria da relação H+/Al3+ em extratos de KCl. Os resultados obtidos sugerem que o Al complexado pela matéria orgânica, em solos orgânicos, é o principal contribuinte para a acidez trocável obtida por titulação. Dessa forma, a recomendação de calagem em solos orgânicos baseado somente na determinação de alumínio trocável por titulação com NaOH deve ser revista.

  2. The debate over robotics in benign gynecology.

    2014-05-01

    The debate over the role of the da Vinci surgical robotic platform in benign gynecology is raging with increasing fervor and, as product liability issues arise, greater financial stakes. Although the best currently available science suggests that, in the hands of experts, robotics offers little in surgical advantage over laparoscopy, at increased expense, the observed decrease in laparotomy for hysterectomy is almost certainly, at least in part, attributable to the availability of the robot. In this author's opinion, the issue is not whether the robot has any role but rather to define the role in an institutional environment that also supports the safe use of vaginal and laparoscopic approaches in an integrated minimally invasive surgery program. Programs engaging robotic surgery should have a clear and self-determined regulatory process and should resist pressures in place that may preferentially support robotics over other forms of minimally invasive surgery.

  3. Robot vision

    International Nuclear Information System (INIS)

    Almost all industrial robots use internal sensors such as shaft encoders which measure rotary position, or tachometers which measure velocity, to control their motions. Most controllers also provide interface capabilities so that signals from conveyors, machine tools, and the robot itself may be used to accomplish a task. However, advanced external sensors, such as visual sensors, can provide a much greater degree of adaptability for robot control as well as add automatic inspection capabilities to the industrial robot. Visual and other sensors are now being used in fundamental operations such as material processing with immediate inspection, material handling with adaption, arc welding, and complex assembly tasks. A new industry of robot vision has emerged. The application of these systems is an area of great potential

    Mobile robots perform fetch-and-carry tasks autonomously. An intelligent, sensor-equipped mobile robot does not require dedicated pathways or extensive facility modification. In the hospital, mobile robots can be used to carry specimens, pharmaceuticals, meals, etc. between supply centers, patient areas, and laboratories. The HelpMate (Transitions Research Corp.) mobile robot was developed specifically for hospital environments. To reach a desired destination, Help-Mate navigates with an on-board computer that continuously polls a suite of sensors, matches the sensor data against a pre-programmed map of the environment, and issues drive commands and path corrections. A sender operates the robot with a user-friendly menu that prompts for payload insertion and desired destination(s). Upon arrival at its selected destination, the robot prompts the recipient for a security code or physical key and awaits acknowledgement of payload removal. In the future, the integration of HelpMate with robot manipulators, test equipment, and central institutional information systems will open new applications in more localized areas and should help overcome difficulties in filling transport staff positions.

    2014-06-01

    This article explores the resonating figures of primate, child, and robot in contemporary technoscientific corporealizations of the 'almost human'. We take as our model (in)organism 'Lucy the Robot Orangutan', roboticist Steve Grand's project to create an artificial life form with a mind of its own. One aspect of Lucy's figuration by Grand, we argue, which ties her to Haraway's analysis of the primate, is of the robot as a model for animal, and more specifically (or aspirationally) human, cognition. We follow the trope of 'model organism' as it is under discussion within science and technology studies and as an ironic descriptor for our own interest in Lucy as an entity/project through which to illuminate figurations within robotics more widely. Primate and robot together are forms of natureculture that help to clarify how the categories of animal and machine are entangled, while making explicit investments in their differences from one another, and from the third category of the human. We conclude, again following Haraway, by imagining what other possibilities there might be for figuring humans, robots, and their relations if we escape the reiterative imaginary of the robot as proxy for becoming human.

    Full Text Available A ortodoxia familiar de construção da paz liberal depende da transplantação e da exportação de condicionalidade e dependência, com vistas a consolidar um contrato social entre populações, seus governos e o Estado, em que repouse uma paz liberal legítima e consensual. O que, com frequência, ocorre, é uma forma híbrida de paz liberal, sujeita a críticas locais poderosas, à resistência, por vezes, e à percepção de que a construção da paz internacional está fracassando em corresponder às expectativas. Em termos kantianos, os problemas com que a paz liberal tem se deparado e a crise pela qual está hoje passando podem ser denominados "retrocesso". Tem sido particularmente notável que a construção da paz liberal não vem sendo capaz de construir políticas unidas a partir de fragmentos territoriais no Kosovo, na Bósnia, no Afeganistão, no Iraque, no Sri Lanka e mesmo na Irlanda do Norte, onde alguns ou todos de seus elementos estão em desenvolvimento. Isso indica uma necessidade ou de reforma do modelo liberal para a paz, ou de estabelecimento de uma capacidade de coexistência desse modelo com alternativas, ou de substituição do modelo. Este artigo examina uma gama de questões inerentes ao paradigma de construção da paz liberal, algumas causas de "retrocesso" e o que pode ser feito no que tange a tais causas, no sentido de utilizar a construção da paz para criar um novo contrato social e atingir o que se poderia muito bem ser uma forma "híbrida liberal-local" de paz.The familiar orthodoxy of liberal peacebuilding depends upon transplanting and exporting conditionality and dependency in order to cement a social contract between populations, their governments and the state, on which rests a legitimate and consensual liberal peace.

    The introduction of robot-assisted surgery represents a milestone in the history of surgery. Today, many surgical disciplines make use of the DaVinci robotic system in performing surgery, even complex ones. Italy stands as one of the countries with a greater diffusion of robotics in surgery, particularly in urological surgery. In Italy, every year, numerous urological surgeries are performed with the DaVinci robot; however, costs of this technology are high and, although likely to decrease, constitute a limit to the spread of the same and restricting its use to shared areas.

    Full Text Available The idea of robotic telesurgery dates back to the 1970s when the National Aeronautics and Space Administration (NASA developed a project to utilize remotely controlled robots to perform surgeries on astronauts. The history of robotic surgery begins in 1985, when Kwoh et al used a robot - Puma 200, for performing neurosurgical biopsies with greater precision. This was soon followed by the introduction of PROBOT in 1988, a robotic system for ultrasound guided prostatic resection. A major breakthrough in the field of robotic surgery came with the performance of the first transatlantic telesurgical procedure (Operation Lindbergh by a surgeon in the United States operating on a patient in France. Laparoscopic cholecystectomy was performed on a 68-year-old lady in Strasbourg, France by Professor Marescaux utilising a Zeus robotic system located in New York, USA. There were no complications during the procedure and the patient was discharged 2 days later. Since then, telesurgery has been carried out in multiple locations around the globe with successful outcomes.

    Tests with robots and the high-fidelity Hubble Space Telescope mockup astronauts use to train for servicing missions have convinced NASA managers it may be possible to maintain and upgrade the orbiting observatory without sending a space shuttle to do the job. In a formal request last week, the agency gave bidders until July 16 to sub-mit proposals for a robotic mission to the space telescope before the end of 2007. At a minimum, the mission would attach a rocket motor to deorbit the telescope safely when its service life ends. In the best case, it would use state-of-the- art robotics to prolong its life on orbit and install new instruments. With the space shuttle off-limits for the job under strict post-Columbia safety policies set by Administrator Sean O'Keefe, NASA has designed a "straw- man" robotic mission that would use an Atlas V or Delta N to launch a 20,ooO-lb. "Hubble Robotic Vehicle" to service the telescope. There, a robotic arm would grapple it, much as the shuttle does.

The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient. The objective of the surgical robot is to correct human deficiencies and improve surgical skills. The capacity of repeating tasks with precision and reproducibility has been the base of the robot´s success. Robotic technology offers objective and measurable advantages: - Improving maneuverability and physical capacity during surgery. - Correcting bad postural habits and tremor. - Allowing depth perception (3D images). - Magnifying strength and movement limits. - Offering a platform for sensors, cameras, and instruments. Endoscopic surgery transformed conceptually the way of practicing surgery. Nevertheless in the last decade, robotic assisted surgery has become the next paradigm of our era. PMID:25643879

    Full Text Available Tomando como ponto de partida o conceito de repetição - tal como ele é desenvolvido na filosofia de Gilles Deleuze - o presente artigo pretende trabalhar a noção de hábito visando à realização de uma crítica à abordagem desta noção feita pela psicologia. Mostra também como a constituição do hábito é inseparável de uma contemplação passiva que se encarrega da fundação do tempo do vivo, demonstrando como é possível pensar a emergência da subjetividade a partir de uma nova inflexão. Visa, portanto, compreender a subjetividade procurando esclarecer a sua emergência à luz de uma perspectiva ontológica e estética, para além da Psicologia.Taking as a start point the concept of repetition - as it's been developed by Gilles Deleuze's philosophy - the article treats the habit notion and, in particular, a critique to the way psychology deals with such notion. In addition, presents how the habit's constitution is inseparable from a passive contemplation, which is responsible for the foundation of the alive time, still showing how possible it is to think about the subjectivity emergence in terms of a new inflection. Therefore, based on an ontology and esthetic perspective, it goals an understanding of subjectivity, as well as its emergence beyond psychology.

    Full Text Available In this paper, we have investigated the concept of "Cultural Robotics" with regard to the evolution of social into cultural robots in the 21st Century. By defining the concept of culture, the potential development of a culture between humans and robots is explored. Based on the cultural values of the robotics developers, and the learning ability of current robots, cultural attributes in this regard are in the process of being formed, which would define the new concept of cultural robotics. According to the importance of the embodiment of robots in the sense of presence, the influence of robots in communication culture is anticipated. The sustainability of robotics culture based on diversity for cultural communities for various acceptance modalities is explored in order to anticipate the creation of different attributes of culture between robots and humans in the future.

    2016-07-01

    Control of the human hand has been both difficult to understand scientifically and difficult to emulate technologically. The article by Santello and colleagues in the current issue of Physics of Life Reviews[1] highlights the accelerating pace of interaction between the neuroscience of controlling body movement and the engineering of robotic hands that can be used either autonomously or as part of a motor neuroprosthesis, an artificial body part that moves under control from a human subject's own nervous system. Motor neuroprostheses typically involve a brain-computer interface (BCI) that takes signals from the subject's nervous system or muscles, interprets those signals through a decoding algorithm, and then applies the resulting output to control the artificial device.

    Surgical operation is still one of the important options for treatment of many types of cancer. In the present-day treatment of cancer, patients' quality of life is focused on and surgeons need to provide minimally invasive surgery without decreasing the curability of disease. Endoscopic surgery contributed to the prevalence of minimally -invasive surgery. However it has also raised a problem regarding differences in surgical techniques among individual surgeons. Robot-assisted surgery provides some resolutions with 3D vision and increases the freedom of forceps manipulation. Furthermore, 3D visual magnification, scaling function, and the filtering function of surgical robots may make it possible for surgeons to perform microsurgery more delicate than open surgery. Here, we report the present status and the future of the representative surgical robot, and the da Vinci surgical system. PMID:22241345

    This chapter focuses on rehabilitation robotics which can be used to augment the clinician's toolbox in order to deliver meaningful restorative therapy for an aging population, as well as on advances in orthotics to augment an individual's functional abilities beyond neurorestoration potential. The interest in rehabilitation robotics and orthotics is increasing steadily with marked growth in the last 10 years. This growth is understandable in view of the increased demand for caregivers and rehabilitation services escalating apace with the graying of the population. We provide an overview on improving function in people with a weak limb due to a neurological disorder who cannot properly control it to interact with the environment (orthotics); we then focus on tools to assist the clinician in promoting rehabilitation of an individual so that s/he can interact with the environment unassisted (rehabilitation robotics). We present a few clinical results occurring immediately poststroke as well as during the chronic phase that demonstrate superior gains for the upper extremity when employing rehabilitation robotics instead of usual care. These include the landmark VA-ROBOTICS multisite, randomized clinical study which demonstrates clinical gains for chronic stroke that go beyond usual care at no additional cost.

    Information and communication technology (ICT) and mechatronics play a basic role in medical robotics and computer-aided therapy. In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery. Localization systems also provide treatments in radiotherapy and radiosurgery with high precision. Virtual or augmented reality plays a role for both surgical training and planning and for safe rehabilitation in the first stage of the recovery from neurological diseases. Also, in the chronic phase of motor diseases, robotics helps with special assistive devices and prostheses. Although, in the past, the actual need and advantage of navigation, localization, and robotics in surgery and therapy has been in doubt, today, the availability of better hardware (e.g., microrobots) and more sophisticated algorithms(e.g., machine learning and other cognitive approaches)has largely increased the field of applications of these technologies,making it more likely that, in the near future, their presence will be dramatically increased, taking advantage of the generational change of the end users and the increasing request of quality in health-care delivery and management.

    Full Text Available Este artículo pretende aportar una contribución a la cuestión de la memoria en la dimensión de la dinámica psíquica, con base en la lógica del pensamiento freudiano. Con este fin se realizó una relectura de la Carta 52, en la que distinguimos las impresiones psíquicas -las huellas de memoria y "fueros"- generados en conformidad con la capacidad del yo de dominar o no la cantidad de excitación. Los primeros están constituidos en el ámbito del principio del placer y los "fueros", a diferencia, indican una memoria literal que no está sujeta a las directrices de este principio. Este hallazgo pone un límite al dominio del principio del placer y al concepto mismo de representación. En esta perspectiva, podemos concebir la psique de una manera amplia, ya que la representación no es la única forma de expresión en el aparato psíquico.

    International Nuclear Information System (INIS)

    This paper describes Robot Vision and Operation System for Nuclear Advanced Robot. This Robot Vision consists of robot position detection, obstacle detection and object recognition. With these vision techniques, a mobile robot can make a path and move autonomously along the planned path. The authors implemented the above robot vision system on the 'Advanced Robot for Nuclear Power Plant' and tested in an environment mocked up as nuclear power plant facilities. Since the operation system for this robot consists of operator's console and a large stereo monitor, this system can be easily operated by one person. Experimental tests were made using the Advanced Robot (nuclear robot). Results indicate that the proposed operation system is very useful, and can be operate by only person. (author)

    Abstract. The citrus industry in Brazil plays a role of great economic, social, generating jobs, income and development. Brazil is the largest producer of citrus, the State of Sergipe stands out in 5th place in national production. Among the many pest problems faced by Brazilian citrus is Citrus Variegated Chlorosis (CVC, known as the yellowing caused by the bacterium Xylella fastidiosa Wells et al. The CVC was officially identified in Brazil in 1987, in orchards of “Triângulo Mineiro” and North and northwest of the state of São Paulo. In the Northeast Region of Brazil, was found in 1996 in the municipality of Boquim Sergipe, and Bahia in 1997, the municipalities of Rio Real and Itapicuru. The aim was to review the literature on the species of leafhoppers vectors of CVC, and verify that occur in the state of Sergipe. The first symptoms are seen in the leaves, then go for the fruits and end up affecting the entire plant, and to be perceived can take between five months and two years. The main vectors of X. fastidiosa in citrus are the sharpshooters of the family Cicadellidae. In Brazil 12 sharpshooters species have already been confirmed. For the state of Sergipe, is scarce information about the Cicadellidae vectors, the data are limited to the northern coast of Bahia, except for vague quote about four genus (Oncometropia, Acrogonia, Dilobopterus and Homolodisca and three species (Homolodisca ignorata Melichar, Acrogonia sp. and Homolodisca spottii Takiya, Cavichioli & McKamey.

    The medical field has many uses for automated and remote-controlled technology. For example, if a tissue sample is only handled in the laboratory by a robotic handling system, then it will never come into contact with a human. Such a system not only helps to automate the medical testing process, but it also helps to reduce the chances of…

    This article addresses prospective and retrospective responsibility issues connected with medical robotics. It will be suggested that extant conceptual and legal frameworks are sufficient to address and properly settle most retrospective responsibility problems arising in connection with injuries caused by robot behaviours (which will be exemplified here by reference to harms occurred in surgical interventions supported by the Da Vinci robot, reported in the scientific literature and in the press). In addition, it will be pointed out that many prospective responsibility issues connected with medical robotics are nothing but well-known robotics engineering problems in disguise, which are routinely addressed by roboticists as part of their research and development activities: for this reason they do not raise particularly novel ethical issues. In contrast with this, it will be pointed out that novel and challenging prospective responsibility issues may emerge in connection with harmful events caused by normal robot behaviours. This point will be illustrated here in connection with the rehabilitation robot Lokomat.

  11. Toward the Automated Synthesis of Cooperative Mobile Robot Teams

    A current limitation in the real-world use of cooperating mobiIe robots is the difficulty in determining the proper team composition for a given robotic application. Present technology restricts the design and implementation of cooperative robot teams to the expertise of a robotics researcher, who has to develop robot teams on an application-specific basis. The objective of our research is to reduce the complexity of cooperative robotic systems through the development of a methodology that enables the automated synthesis of cooperative robot teams. We propose an approach to this problem that uses a combination of the theories of sensori-computational systems and information invariants, building on the earlier work of Donald, Rus, et al. We describe the notion of defining equivalence classes that serve as fundamental building blocks of more complex cooperative mobile robot behaviors. We postulate a methodology for framing mission requirements in terms of the goals and constraints of the problem, incorporating issues such as multi-robot interference, communication, control strategy, robot complexity, and so forth, into the mechanism. Our initial work restricts the robot application and design space to three multi-robot application domains we have previously studied and implemented: keeping formation, "mock" hazardous waste cleanup, and cooperative observation. This paper presents the foundational ideas upon which our approach to cooperative team design is based. Keywords: Cooperative behaviors, behavior synthesis, multi-robot learning

    This thesis studies aspects of self-sufficient energy (energy autonomy) for truly autonomous robots and towards sociable robots. Over sixty years of history of robotics through three developmental ages containing single robot, multi-robot systems, and social (sociable) robots, the main objective...... of roboticists mostly focuses on how to make a robotic system function autonomously and further, socially. However, such approaches mostly emphasize behavioural autonomy, rather than energy autonomy which is the key factor for not only any living machine, but for life on the earth. Consequently, self......-sufficient energy is one of the challenges for not only single robot or multi-robot systems, but also social and sociable robots. This thesis is to deal with energy autonomy for multi-robot systems through energy sharing (trophallaxis) in which each robot is equipped with two capabilities: self-refueling energy...

    Full Text Available We discuss the capabilities of continuum (continuous backbone robot structures in the performance of under-actuated grasping. Continuum robots offer the potential of robust grasps over a wide variety of object classes, due to their ability to adapt their shape to interact with the environment via non-local continuum contact conditions. Furthermore, this capability can be achieved with simple, low degree of freedom hardware. However, there are practical issues which currently limit the application of continuum robots to grasping. We discuss these issues and illustrate via an experimental continuum grasping case study.

    Krebs, Herman Igo; Hogan, Neville

    2012-11-01

    The last two decades have seen a remarkable shift in the neurorehabilitation paradigm. Neuroscientists and clinicians moved away from the perception that the brain is static and hardwired to a new dynamic understanding that plasticity is a fundamental property of the adult human brain and might be harnessed to remap or create new neural pathways. Capitalizing on this innovative understanding, the authors introduced a paradigm shift in the clinical practice in 1989 when they initiated the development of the Massachusetts Institute of Technology-Manus robot for neurorehabilitation and deployed it in the clinic in 1994 (Krebs et al. 1998). Since then, the authors and others have developed and tested a multitude of robotic devices for stroke, spinal cord injury, cerebral palsy, multiple sclerosis, and Parkinson disease. Here, the authors discuss whether robotic therapy has achieved a level of maturity to justify its broad adoption in the clinical realm as a tool for motor recovery. PMID:23080044

    Kim, Sangbae; Laschi, Cecilia; Trimmer, Barry

    2013-05-01

    Animals exploit soft structures to move effectively in complex natural environments. These capabilities have inspired robotic engineers to incorporate soft technologies into their designs. The goal is to endow robots with new, bioinspired capabilities that permit adaptive, flexible interactions with unpredictable environments. Here, we review emerging soft-bodied robotic systems, and in particular recent developments inspired by soft-bodied animals. Incorporating soft technologies can potentially reduce the mechanical and algorithmic complexity involved in robot design. Incorporating soft technologies will also expedite the evolution of robots that can safely interact with humans and natural environments. Finally, soft robotics technology can be combined with tissue engineering to create hybrid systems for medical applications.

    Full Text Available Almost all cases of sporadic amyotrophic lateral sclerosis (ALS, and some cases of the familial form, are characterised by the deposition of TDP-43, a member of a family of heteronuclear ribonucleoproteins (hnRNP. Although protein misfolding and deposition is thought to be a causative feature of many of the most prevalent neurodegenerative diseases, a link between TDP-43 aggregation and the dysfunction of motor neurons has yet to be established, despite many correlative neuropathological studies. We have investigated this relationship in the present study by probing the effect of altering TDP-43 aggregation behaviour in vivo by modulating the levels of molecular chaperones in a Drosophila model. More specifically, we quantify the effect of either pharmacological upregulation of the heat shock response or specific genetic upregulation of a small heat shock protein, CG14207, on the neurotoxicity of both TDP-43 and of its disease associated 25 kDa fragment (TDP-25 in a Drosophila model. Inhibition of the aggregation of TDP-43 by either method results in a partial reduction of its neurotoxic effects on both photoreceptor and motor neurons, whereas inhibition of the aggregation of TDP-25 results not only in a complete suppression of its toxicity but also its clearance from the brain in both neuronal subtypes studied. The results demonstrate, therefore, that aggregation plays a crucial role in mediating the neurotoxic effects of both full length and truncated TDP-43, and furthermore reveal that the in vivo propensity of these two proteins to aggregate and their susceptibility to molecular chaperone mediated clearance are quite distinct.

  15. Beyond synergies. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    2016-07-01

    The target paper by Santello et al. [1] uses the observation that hand shape during grasping can be described by a small set of basic postures, or "synergies," to describe the possible neural basis of motor control during this complex behavior. In the literature, the term "synergy" has been used with a number of different meanings and is still loosely defined, making it difficult to derive concrete analogs of corresponding neural structure. Here, I will define "synergy" broadly, as a set of parameters bound together by a pattern of correlation. With this definition, it can be argued that behavioral synergies are just one facet of the correlational structuring used by the brain to generate behavior. As pointed out in the target article, the structure found in synergies is driven by the physical constraints of our bodies and our surroundings, combined with the behavioral control imparted by our nervous system. This control itself is based on correlational structure which is likely to be a fundamental property of brain function.

    The need for automated welding repair systems of marine structures, ship hulls and nuclear installations had lead to an increasing demand for subsea robots. Considering the application of friction welding to perform underwater repairs, a TRICEPT TR600 robot has been identified as the most suitable system to withstand the high reaction forces characteristic of this process. This study reviews initially the research and development work carried out at GKSS to modify and test a Siemens-MANUTEC robot. After a description of the TRICEPT TR600 robot a marinization concept is presented and discussed in detail. Problems of galvanic corrosion in seawater are addressed in a separate chapter. The deflection of the robot in subsea water currents is estimated with a worst-case calculation. (orig.)

    The project I am working on at NASA-Johnson Space Center in Houston, TX is a hexapod robot. This project was started by various engineers at the Trick Lab. The goal of this project is to have the hexapod track a yellow ball or possibly another object from left to right and up/down. The purpose is to have it track an object like a real creature. The project will consist of using software and hardware. This project started with a hexapod robot which uses a senor bar to track a yellow ball but with a limited field of vision. The sensor bar acts as the robots "head." Two servos will be added to the hexapod to create flexion and extension of the head. The neck and head servos will have to be programmed to be added to the original memory map of the existing servos. I will be using preexisting code. The main programming language that will be used to add to the preexisting code is C++. The trick modeling and simulation software will also be used in the process to improve its tracking and movement. This project will use a trial and error approach, basically seeing what works and what does not. The first step is to initially understand how the hexapod works. To get a general understanding of how the hexapod maneuvers and plan on how to had a neck and head servo which works with the rest of the body. The second step would be configuring the head and neck servos with the leg servos. During this step, limits will be programmed specifically for the each servo. By doing this, the servo is limited to how far it can rotate both clockwise and counterclockwise and this is to prevent hardware damage. The hexapod will have two modes in which it works in. The first mode will be if the sensor bar does not detect an object. If the object it is programmed to look for is not in its view it will automatically scan from left to right 3 times then up and down once. The second mode will be if the sensor bar does detect the object. In this mode the hexapod will track the object from left to

    Full Text Available As cerâmicas de carbeto de silício, SiC, apresentam excelentes propriedades quando obtidas por infiltração de determinados líquidos. Na infiltração o tempo de contato entre o líquido e o SiC a temperaturas elevadas é muito curto, diminuindo a probabilidade de formação dos produtos gasosos que interferem negativamente na resistência da peça final, como ocorre na sinterização via fase líquida. O objetivo deste trabalho é mostrar uma correlação entre molhabilidade e capacidade de infiltração de alguns aditivos em compactos de SiC. Foram preparados compactos de SiC por prensagem isostática a frio e posterior pré-sinterização via fase sólida. Nesses compactos foram infiltradas misturas de Y2O3-AlN, Y2O3-Al2O3, R2O3-AlN, nas composições eutéticas, 10 ºC acima da temperatura de fusão das respectivas misturas por 4, 8 e 12 min. Após infiltração, as amostras foram analisadas quanto à densidade aparente e real, fases cristalinas, microestrutura e grau de infiltração, sendo que as amostras infiltradas com Y2O3-AlN apresentaram melhores resultados.Silicon carbide ceramics, SiC, obtained by liquid infiltration have shown excellent properties. In infiltration process the contact time of the liquid with SiC at elevated temperature is short, decreasing the probability to form gaseous products that contribute negatively in the final product properties. This phenomenon occurs during SiC liquid phase sintering. The purpose of the present study was to investigate the correlation between wettability and infiltration tendency of some additives in SiC compacts. SiC compacts were prepared by cold isostatic pressing followed by solid phase pre-sintering. Into the compacts were introduced Y2O3-AlN, Y2O3-Al2O3, R2O3-AlN liquids with eutectic compositions at a temperature 10 ºC higher than the melting point of each mixture for 4, 8 and 12 min. Before infiltration, the samples were analyzed by determining densities, crystalline phases

    Full Text Available La tendencia moderna a objetivar la responsabilidad civil ha generado diferentes incoherencias sistémicas que exigen la introducción de elementos de equilibrio entre la responsabilidad subjetiva y la responsabilidad objetiva. Ante la permanente infracción al principio de la tipicidad, se propone como vía de equilibrio el reconocimiento del principio según el cual no puede haber responsabilidad objetiva sin limitación cuantitativa de la indemnización. Sin embargo, este principio entraría aparentemente en contradicción con otro, denominado principio de la reparación integral del daño. El artículo analiza dicha posible contradicción desde el fundamento moral de ambas clases de responsabilidad, así como del principio de la reparación integral del daño. Además, profundiza la problemática a partir de su elemento esencial, como es el daño resarcible, de modo de verificar qué elementos puede aportar a este aquel principio. En esta perspectiva, se estudia si tiene verdaderamente un carácter normativo, y qué cambios a su respecto produce su reconocimiento expreso a nivel legal o constitucional. Por último, se trata el principio de la reparación integral bajo un concepto distinto al tradicional y que ha venido sosteniéndose en los últimos años, a fin de confrontarlo con la citada contradicción. Al término del artículo, se sintetizan las conclusiones alcanzadas, las cuales concuerdan con la inexistencia de la contradicción entre el principio según el cual no hay responsabilidad objetiva sin limitación cuantitativa y el principio de la reparación integral del daño.

    A robot platform includes perceptors, locomotors, and a system controller. The system controller executes a robot intelligence kernel (RIK) that includes a multi-level architecture and a dynamic autonomy structure. The multi-level architecture includes a robot behavior level for defining robot behaviors, that incorporate robot attributes and a cognitive level for defining conduct modules that blend an adaptive interaction between predefined decision functions and the robot behaviors. The dynamic autonomy structure is configured for modifying a transaction capacity between an operator intervention and a robot initiative and may include multiple levels with at least a teleoperation mode configured to maximize the operator intervention and minimize the robot initiative and an autonomous mode configured to minimize the operator intervention and maximize the robot initiative. Within the RIK at least the cognitive level includes the dynamic autonomy structure.

    Full Text Available Introduction. Transoral robotic surgery is a step forward in the evolution of minimally invasive surgery in the head and neck, optimizing the two basic requirements of such surgical approaches: excellent vision and freedom of handling. Its development since 2009 has been explosive. Materials and Methods. We describe the technical aspects of the da Vinci robotic surgery system and the basic surgical procedures (radical tonsillectomy, resection of the tongue base and supraglottic laryngectomy. Through a literature review we present the available clinical experience .Results. Transoral robotic surgery has been applied mainly for head and neck cancer. Large enough series have been published with functional and oncological results, which are comparable to those with the standard techniques. Robotic surgery particularly widens the possibilities for the transoral approach to the oropharynx. The surgical approach to the base of the tongue also opens new possibilities in the management of sleep apnea. The robotic approaches to the skull base are still experimental. Discussion. Available data support the use of transoral robotic surgery and prompt towards substantial changes in the management protocols for head and neck cancer.

    Animals exploit soft structures to move effectively in complex natural environments. These capabilities have inspired robotic engineers to incorporate soft technologies into their designs. The goal is to endow robots with new, bioinspired capabilities that permit adaptive, flexible interactions with unpredictable environments. Here, we review emerging soft-bodied robotic systems, and in particular recent developments inspired by soft-bodied animals. Incorporating soft technologies can potentially reduce the mechanical and algorithmic complexity involved in robot design. Incorporating soft technologies will also expedite the evolution of robots that can safely interact with humans and natural environments. Finally, soft robotics technology can be combined with tissue engineering to create hybrid systems for medical applications. PMID:23582470

    Full Text Available Neste artigo, apresento uma análise dos aspectos historiográficos da obra de Hans Ulrich Gumbrecht. Acompanhado o desenvolvimento de sua teoria da modernidade e das conseqüências dessa teoria para a escrita da história e para a auto-consciência disciplinar. Por fim, proponho uma releitura da história da historiografia através dos dois tipos de culturas propostas por Gumbrecht, ou seja, culturas de sentido e culturas de presença. Argumento que mesmo que a historiografia moderna possa ser caracterizada como predominantemente ancorada na produção de sentido, aspectos centrais de sua história só podem ser explicados através de elementos típicos da produção de presença.This paper analyses some historiographical aspects of Hans Ulrich Gumbrecht's work, particularly his theory of modernity and its consequences to the writing of history and its disciplinary self-conscious. Finally, it is proposed a reinterpretation of the history of historiography based on the distinction between cultures of presence and cultures of meaning. It is argued that despite the fact that the elements of meaning are predominant in the constitution of modern historiography, the forces acting in its constitution cannot be explained without typical elements of a culture of presence.

    Full Text Available Quatro bioensaios, dois em casa de vegetação e dois em laboratório, foram conduzidos com o objetivo de identificar biótipos de Euphorbia heterophylla (EPHHL com resistência múltipla a inibidores da ALS e da PROTOX. Em casa de vegetação, plantas do biótipo suscetível (S e dos biótipos 4 e 23, suspeitos de resistência múltipla, foram aspergidas com diferentes doses de imazethapyr e fomesafen. Nos bioensaios em laboratório, sementes dos biótipos S e 4 foram depositadas em placas de Petri contendo diferentes concentrações dos mesmos herbicidas. Curvas de dose-resposta foram ajustadas, utilizando os modelos logístico e polinomial, respectivamente, para os dados obtidos em casa de vegetação e em laboratório. Em casa de vegetação, o fator de resistência (FR a imazethapyr para o biótipo 4 foi superior a 24, enquanto para o biótipo 23 ele foi de 15. Os FRs a fomesafen foram, respectivamente, de 62 e 39, para os mesmos biótipos. Em um período de 144 horas, concentrações de imazethapyr e fomesafen no bioensaio em laboratório foram capazes de discriminar os crescimentos da parte aérea e radicular dos biótipos de EPHHL com resistência múltipla e S. Os resultados confirmam ser tanto os testes em casa de vegetação quanto os laboratoriais, utilizando placas de Petri, metodologias apropriadas para discriminar biótipos de EPHHL S daqueles com resistência múltipla.Four bioassays were developed under greenhouse and laboratory conditions to identify Euphorbia heterophylla (EPHHL biotypes with multiple resistance to PROTOX and ALS-inhibiting herbicides. In the greenhouse bioassays, plants of a susceptible (S biotype and of two biotypes suspected of multiple resistance (#4 and #23 were sprayed using different levels of the herbicides imazethapyr and fomesafen. The laboratory bioassays consisted of a comparative test between biotypes S and #4, exposed to germination in imazethapyr and fomesafen solutions. Dose

  1. Robots Social Embodiment in Autonomous Mobile Robotics

    2008-11-01

    Full Text Available This work aims at demonstrating the inherent advantages of embracing a strong notion of social embodiment in designing a real-world robot control architecture with explicit ?intelligent? social behaviour between a collective of robots. It develops the current thinking on embodiment beyond the physical by demonstrating the importance of social embodiment. A social framework develops the fundamental social attributes found when more than one robot co-inhabit a physical space. The social metaphors of identity, character, stereotypes and roles are presented and implemented within a real-world social robot paradigm in order to facilitate the realisation of explicit social goals.

    2007-03-01

    ZAPATA ENGINEERING challenged our engineers and scientists, which included robotics expertise from Carnegie Mellon University, to design a solution to meet our client's requirements for rapid digital geophysical and radiological data collection of a munitions test range with no down-range personnel. A prime concern of the project was to minimize exposure of personnel to unexploded ordnance and radiation. The field season was limited by extreme heat, cold and snow. Geographical Information System (GIS) tools were used throughout this project to accurately define the limits of mapped areas, build a common mapping platform from various client products, track production progress, allocate resources and relate subsurface geophysical information to geographical features for use in rapidly reacquiring targets for investigation. We were hopeful that our platform could meet the proposed 35 acres per day, towing both a geophysical package and a radiological monitoring trailer. We held our breath and crossed our fingers as the autonomous Speedrower began to crawl across the playa lakebed. We met our proposed production rate, and we averaged just less than 50 acres per 12-hour day using the autonomous platform with a path tracking error of less than +/- 4 inches. Our project team mapped over 1,800 acres in an 8-week (4 days per week) timeframe. The expertise of our partner, Carnegie Mellon University, was recently demonstrated when their two autonomous vehicle entries finished second and third at the 2005 Defense Advanced Research Projects Agency (DARPA) Grand Challenge. 'The Grand Challenge program was established to help foster the development of autonomous vehicle technology that will some day help save the lives of Americans who are protecting our country on the battlefield', said DARPA Grand Challenge Program Manager, Ron Kurjanowicz. Our autonomous remote-controlled vehicle (ARCV) was a modified New Holland 2550 Speedrower retrofitted to allow the machine

    A modular robot may comprise a main body having a structure defined by a plurality of stackable modules. The stackable modules may comprise a manifold, a valve module, and a control module. The manifold may comprise a top surface and a bottom surface having a plurality of fluid passages contained therein, at least one of the plurality of fluid passages terminating in a valve port located on the bottom surface of the manifold. The valve module is removably connected to the manifold and selectively fluidically connects the plurality of fluid passages contained in the manifold to a supply of pressurized fluid and to a vent. The control module is removably connected to the valve module and actuates the valve module to selectively control a flow of pressurized fluid through different ones of the plurality of fluid passages in the manifold. The manifold, valve module, and control module are mounted together in a sandwich-like manner and comprise a main body. A plurality of leg assemblies are removably connected to the main body and are removably fluidically connected to the fluid passages in the manifold so that each of the leg assemblies can be selectively actuated by the flow of pressurized fluid in different ones of the plurality of fluid passages in the manifold.

    Due to their numerous advantages, mainly in terms of patient benefit, mini-invasive robotically assisted interventions are gaining in importance in various surgical fields. However, this conversion has its own challenges that stem from both its novelty and complexity. In this paper we propose to accompany the surgeons in their transition, by offering an integrated environment that enables them to make better use of this new technology. The proposed system is patient-dependent, and enables the planning, validation, simulation, teaching and archiving of robotically assisted interventions. The approach is illustrated for a coronary bypass graft using the daVinci tele-operated robot. PMID:12161911

    Robotic-assisted laparoscopic hysterectomies are being performed at higher rates since the da Vinci Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA, USA) received US Food and Drug Administration approval in 2005 for gynecologic procedures. Despite the technological advancements over traditional laparoscopy, a discrepancy exists between what the literature states and what the benefits are as seen through the eyes of the end-user. There remains a significant learning curve in the adoption of safe and efficient robotic skills. The authors present important considerations when choosing to perform a robotic hysterectomy and a step-by-step technique. The literature on perioperative outcomes is also reviewed. PMID:27521880

    Nephron-sparing surgery has been proven to positively impact the postoperative quality of life for the treatment of small renal tumors, possibly leading to functional improvements. Laparoscopic partial nephrectomy is still one of the most demanding procedures in urological surgery. Laparoscopic partial nephrectomy sometimes results in extended warm ischemic time and severe complications, such as open conversion, postoperative hemorrhage and urine leakage. Robot-assisted partial nephrectomy exploits the advantages offered by the da Vinci Surgical System to laparoscopic partial nephrectomy, equipped with 3-D vision and a better degree in the freedom of surgical instruments. The introduction of the da Vinci Surgical System made nephron-sparing surgery, specifically robot-assisted partial nephrectomy, safe with promising results, leading to the shortening of warm ischemic time and a reduction in perioperative complications. Even for complex and challenging tumors, robotic assistance is expected to provide the benefit of minimally-invasive surgery with safe and satisfactory renal function. Warm ischemic time is the modifiable factor during robot-assisted partial nephrectomy to affect postoperative kidney function. We analyzed the predictive factors for extended warm ischemic time from our robot-assisted partial nephrectomy series. The surface area of the tumor attached to the kidney parenchyma was shown to significantly affect the extended warm ischemic time during robot-assisted partial nephrectomy. In cases with tumor-attached surface area more than 15 cm(2) , we should consider switching robot-assisted partial nephrectomy to open partial nephrectomy under cold ischemia if it is imperative. In Japan, a nationwide prospective study has been carried out to show the superiority of robot-assisted partial nephrectomy to laparoscopic partial nephrectomy in improving warm ischemic time and complications. By facilitating robotic technology, robot-assisted partial nephrectomy

    Full Text Available A resistência de biótipos de plantas daninhas aos herbicidas inibidores da acetolactato sintase (ALS é causada pela insensibilidade desta enzima aos herbicidas que inibem sua atividade catalítica. A insensibilidade da enzima é decorrente de uma alteração estrutural, resultado da substituição de certos aminoácidos no sítio de ação do herbicida. Esta alteração na enzima pode eventualmente resultar, além da resistência ao herbicida, em modificações na taxa de crescimento da planta, fato este comprovado para os biótipos resistentes aos herbicidas inibidores do fotossistema II, os quais apresentam taxa de crescimento prejudicada pela alteração no sítio de ação sofrida pelo herbicida. Esta possível diminuição na taxa de crescimento da planta resistente tem conseqüências diretas na competitividade do biótipo e, portanto, na sua dinâmica dentro da população, afetando diretamente as estratégias de manejo da resistência. A presente pesquisa foi desenvolvida com o objetivo de comparar a taxa de crescimento de dois biótipos da planta daninha picão-preto (Bidens pilosa, sendo um resistente e um suscetível aos herbicidas inibidores da ALS. Um experimento foi montado em casa de vegetação, em vasos com capacidade de 5 L, sendo uma planta de cada biótipo por vaso, coletando-se a biomassa seca destas plantas e a área foliar semanalmente, iniciando-se 14 dias após o plantio.

Desta análise, foram derivadas a taxa de crescimento absoluto (TCA, a taxa de crescimento relativo (TCR e a taxa de assimilação fotossintética líquida (TAL. O biótipo suscetível apresentou peso de biomassa seca superior ao resistente nas primeiras fases do crescimento, porém no final do ciclo o biótipo resistente igualou-se em tamanho de área foliar, pois apresentou, principalmente no início do ciclo de crescimento

    2011-10-01

    Despite the extensive use of robotics in the adult population, the use of robotics in pediatrics has not been well accepted. There is still a lack of awareness from pediatric surgeons on how to use the robotic equipment, its advantages and indications. Benefit is still controversial. Dexterity and better visualization of the surgical field are one of the strong values. Conversely, cost and a lack of small instruments prevent the use of robotics in the smaller patients. The aim of this manuscript is to present the controversies about the use of robotics in pediatric surgery.

Esse artigo, inserido em uma pesquisa do campo da Ethics of Enhancement Human Beings, pretende excogitar um novo conceito para compreender nuances da chamada Genetic Age até agora aparentemente negligenciadas por outros dois conceitos já disponíveis, a saber, biopolítica e biossociabilidade. Para tanto, recorremos à revisão de parte da bibliografia sobre o tema e à análise e crítica desses conceitos, os quais focalizam a temática fundamentalmente através das noções de gestão de riscos e promoção da vida saudável. O objetivo foi apontar a parcial pertinência da grade de inteligibilidade fornecida por eles para compreender a nova genética. Destarte, apresentamos o conceito de biodesign como uma alternativa complementar. Com ele, esperamos oferecer, introdutoriamente, um conceito que apreenda, sobretudo, o que as possibilidades de artificialização da vida humana representam para além de uma nova forma de gestão de riscos/promoção da saúde.The new genetics would point to a new era of metamorphosis of the human, which would be marked by the prominence of that in the selection and improvement of their nature.

    The book gives a comprehensive overview of the state-of-the-art research and engineering in theory and application of Lattice Automata in design and control of autonomous Robots. Automata and robots share the same notional meaning. Automata (originated from the latinization of the Greek word “αυτόματον”) as self-operating autonomous machines invented from ancient years can be easily considered the first steps of robotic-like efforts. Automata are mathematical models of Robots and also they are integral parts of robotic control systems. A Lattice Automaton is a regular array or a collective of finite state machines, or automata. The Automata update their states by the same rules depending on states of their immediate neighbours. In the context of this book, Lattice Automata are used in developing modular reconfigurable robotic systems, path planning and map exploration for robots, as robot controllers, synchronisation of robot collectives, robot vision, parallel robotic actuators.

    2006-02-01

    After the emergence of robotically assisted systems in laparoscopic surgery more than 15 years ago, several systems have been on the market. At the time being only one system, the da Vinci surgical system (Intuitive Surgical, Sunnyvale, CA, USA), has survived in clinical use with an increasing spread particularly among adult urologists used primarily for radical prostatectomies. However, the reconstructive nature of paediatric urology makes the system interesting for the paediatric urologists, since its strength is laparoscopic suturing and difficult dissection. So far only few reports have been published about its clinical use in paediatric urology. The main advantages are the 3D magnified view, the wrist-like movements of the instruments, and the scaling and precision of instrument movements. The system has been used for upper tract reconstruction like pyeloplasties and heminephrectomies, both for the transperitoneal and, more technical challenging, the retroperitoneal approach. In the pelvic region, anti-reflux surgery (both extra- and intravesically) and surgery for malformations of the internal genitalia like utriculus cysts and gonadal streaks are feasible. More simple procedures like nephrectomies and the management of the intra-abdominal testis are not justified due to the high costs. In addition, no advantage for the patients related to standard laparoscopic procedures has been proofed yet. For the surgeon the minimally challenging invasive procedures become feasible with certainly improved ergonomics. The use of the system is much easier than standard laparoscopic surgery and its widespread will give more patients to access minimal invasive surgery. PMID:18947593

    Japan has been one of the most successful countries in the world in the realm of terrestrial robot applications. The panel found that Japan has in place a broad base of robotics research and development, ranging from components to working systems for manufacturing, construction, and human service industries. From this base, Japan looks to the use of robotics in space applications and has funded work in space robotics since the mid-1980's. The Japanese are focusing on a clear image of what they hope to achieve through three objectives for the 1990's: developing long-reach manipulation for tending experiments on Space Station Freedom, capturing satellites using a free-flying manipulator, and surveying part of the moon with a mobile robot. This focus and a sound robotics infrastructure is enabling the young Japanese space program to develop relevant systems for extraterrestrial robotics applications.

    Full Text Available Robotic assistance is one of the latest additions to the field of laparoscopic surgery. The most commonly used robotic device in Urology is the da Vinci ® system of which over 200 devices are installed worldwide including 3 in India. This robot consists of three or four arms, one of which is used to hold and manipulate the laparoscopic camera while the others are used to manipulate specialized laparoscopic instruments with endowrist ® technology that allows 7 degrees of freedom. The robot is currently used primarily for radical prostatectomies where complex dissection and reconstruction can be performed in less than 2 hours with excellent outcomes. There is a progressive increase in the number of surgeries being performed by this device which allows laparoscopy naοve surgeons to offer the benefits of minimally invasive surgery to their patients. The other surgeries where this device has been used to benefit are pyeloplasty, cystectomy with urinary diversion, nephrectomy and ureteric re-implant. The principal drawbacks of the device are the steep cost of machine and disposables. However, the benefits achieved in terms of improved surgical precision, magnified 3 dimensional vision, scaling of movements, remote surgery and as a teaching tools will help the robot establish a definitive place in the urologic armamentarium.

    In this study we explored possible applications of the da Vinci system in approaching the skull base at optic chiasm level on two cryopreserved cadavers, using an entirely transoral robotic technique (TORS). We used a standard 12 mm endoscopy and 8 mm terminals. Bone drilling was performed manually. The da Vinci system is equipped with very good illumination and 3D viewing, thus providing excellent vision and great maneuverability even in the less accessible areas of the skull. Our experience demonstrates that an entirely transoral skull base robotic approach to this complex anatomical region has many advantages as compared to traditional techniques. PMID:24077869

    Full Text Available Este foi um estudo de natureza qualitativa, que teve como objetivo compreender, a partir da experiência de mulheres que se tornaram mães na adolescência, o significado da maternidade no contexto de vida destas mães. Participaram 14 mulheres na faixa etária de 20 a 24 anos, residentes na periferia de Maceió, capital do estado de Alagoas. A coleta de informação foi realizada por meio de entrevistas, utilizando a história oral temática como procedimento metodológico. Foram construídas narrativas, a partir das histórias de vida das mulheres, posteriormente, analisadas à luz do referencial de gênero. Observamos que as entrevistadas tiveram sua iniciação sexual durante o período de namoro quando não haviam recebido orientações prévias sobre sexualidade ou saúde reprodutiva. Algumas mulheres conviviam com seus parceiros quando aconteceu a gravidez, porém, mesmo assim, consideraram esse fato inesperado. Houve aceitação da gravidez pela maioria delas, e também ocorreu a união, ainda que não de maneira legalizada, de muitos casais que não viviam juntos. Tentativas de abortamento, quando da não-aceitação imediata do parceiro, foram relatadas. As questões de gênero mostram-se presentes nas relações conjugais, com os parceiros figurando como provedores da família e as mulheres mantidas sob sua dependência, centradas no ambiente doméstico, assumindo responsabilidade pelo cuidado da casa, dos filhos e do companheiro. Os homens agiam mais livremente, mantendo relações extraconjugais e chegavam a agredir suas mulheres, em casa. Apesar de ressentidas com essa atitude dos companheiros, elas mantinham o relacionamento com eles. As entrevistadas deixaram explícito que lamentavam a perda da liberdade, do lazer, da oportunidade de trabalho e de estudo ao assumirem a maternidade. Por outro lado, enfatizaram seu não-arrependimento por terem levado a gravidez até o fim. Assim o cotidiano dessas mulheres parece centralizado no

A palavra apoio é, geralmente, apresentada, em documentos oficiais do Ministério da Saúde e em publicações acadêmico-científicas, acompanhada por descritores que a caracterizam. É comum encontrarmos diferentes terminologias: “apoio institucional”, “apoio à gestão”, “apoio matricial”. Quanto ao NASF, publicações examinadas destacam a centralidade do desempenho do apoio matricial. No entanto, nos perguntamos: quais as faces que a função apoio vem assumindo na implementação deste programa? Para refletir sobre essa e outras questões, desenvolvemos uma pesquisa de caráter qualitativo em uma equipe de NASF, no interior do Paraná, utilizando-nos das ferramentas metodológicas: observação participante, entrevista semiestruturada e grupos de discussão. Procuramos demonstrar que a dinâmica da função apoio no NASF permite a emergência tanto do apoio matricial quanto do apoio institucional.

    Full Text Available Este artículo presenta una aplicación eficiente de un control por modelo de referencia sobre un robot de tipo SCARA. El control estudiado es un control predictivo funcional, el que hace uso de un modelo dinámico simplificado del robot. Los ensayos simulados se realizan sobre un robot de cuatro grados de libertad, tipo SCARA. Con el fin de comparar diferentes estrategias de control, se diseña un controlador clásico tipo PID y dos controladores basados en el modelo de referencia. En este último caso el sistema se linealiza y se desacoplada por realimentación, lo que transforma el sistema a controlar en un simple par de integradores. Al sistema lineal y desacoplado resultante se le aplica el control por par calculado y el control predictivo funcional. Los tres controladores estudiados se simulan sobre el robot SCARA con valores numéricos reales. Las pruebas permiten valorar las respuestas de estos controladores en seguimiento de trayectoria, rechazo de perturbaciones y presencia de errores en el modelado con consignas complejas similares a las utilizadas en procesos de fabricación.This paper describes an efficient approach for model based control, applied on a SCARA robot. The studied control is the predictive functional control which uses a simplified dynamical model of the robot. The simulated tests are made on a SCARA type robot, with four DOF. To compare several control strategies, a classical PID control and two model based controllers are designed. In the last case, the model is first linearized and decoupled by feedback, transforming the system into a double set of integrators. Computed torque control and predictive functional control are applied to the linear and decoupled system. The three studied controllers are simulated on the SCARA robot with real numerical values. Tracking performance, disturbance rejection and model robot mismatch are enlightened, using complex machining tasks trajectories and error presence in the modelling

Aluminosilicates as andalusite submitted to aluminium reduction and the simultaneous nitriding (N2 atmosphere leads to the obtention of alumina and phases of the Si-Al-O-N system. These phases are of great interest for structural ceramics. Mixes prepared with andalusite and Al° (different content were treated with N2 up to 1550 °C., using a heating rate of 5 °/min. Thermal effects (DTA and weight changes (TG, DTG of nitriding reactions during heating were evaluated. The reaction mechanism was determined using DTA-TG-DTG techniques. Results indicate that Si° and AlN are important intermediate phases during reactions. The final products were a-Al2O3 with sialons, mainly b’ phase and polytype sialons.

    Full Text Available A utilização intensiva do glyphosate nas lavouras de soja Roundup Ready® (RR no Rio Grande do Sul (RS, nos últimos anos, pode ter selecionado biótipos de leiteira (Euphorbia heterophylla resistentes ao herbicida. Esse cenário dificultará ainda mais o manejo da espécie, já que permanecem indícios da presença de biótipos resistentes também em herbicidas inibidores da acetolactato sintase (ALS. Assim, os objetivos deste trabalho foram avaliar a sensibilidade da leiteira a herbicidas inibidores da ALS e ao glyphosate, verificar a distribuição dos biótipos resistentes no RS e determinar os principais fatores agronômicos associados a falhas de controle. Para isso, amostras de sementes de plantas de leiteira foram coletadas em lavouras de soja RR localizadas em 56 municípios do Estado do RS. Por ocasião das coletas, os agricultores responderam a questionário que abordava o manejo das plantas daninhas na área. Usando-se as sementes coletadas, foram conduzidos dois experimentos em casa de vegetação: no primeiro, avaliou-se a resposta de 86 biótipos ao herbicida glyphosate, aplicado na dose de 2.160 g e.a. ha-1; e, no segundo, a resposta de 73 biótipos ao herbicida imazethapyr, aplicado na dose de 200 g i.a. ha-1. Os resultados obtidos evidenciam que todos os biótipos de leiteira avaliados são suscetíveis ao glyphosate, porém existem biótipos resistentes aos inibidores da ALS. As respostas do questionário indicam que práticas de manejo como uso de subdoses e/ou utilização intensiva do glyphosate e a ausência de rotação de culturas favorecem falhas no controle de leiteira pelo herbicida glyphosate em soja.The intensive use of glyphosate in Roundup Ready® (RR soybean fields in Rio Grande do Sul (RS, in recent years may have selected wild poinsettia (Euphorbia heterophylla biotypes resistant to the herbicide.

    Full Text Available Problematizando o racismo e os processos de discriminação sociocultural, discute-se a questão da diferença na educação, por meio de estudos recentes que focalizam os campos das relações étnicas, geracionais, de gênero, assim como das diferenças físicas e mentais. Tendo como referência Bhabha, Pierucci, Scott, Skliar e, de modo particular, jovens pesquisadores que se apresentaram na 25ª Reunião Anual da ANPEd, busca-se compreender as motivações construídas nos processos identitários relativos à diferença. Conclui-se que as novas perspectivas emergentes de compreensão das diferenças indicam uma visão mais complexa do diferente, para além do paradigma da diversidade. Deste modo, surge o campo híbrido, fluido, polissêmico, ao mesmo tempo promissor, da diferença, que se constitui nos entrelugares das enunciações de distintos sujeitos e das múltiplas identidades socioculturais.Questioning racism and the sociocultural discrimination processes, we discuss the issue of difference in education through recent studies focusing on the fields of ethnic, generational, and gender relationships as well as of physical and mental differences. Drawing on Bhabha, Pierucci, Scott, Skliar, as well as on young researchers who took part in the 25th Annual meeting of the ANPED, we seek to understand the motivations built in the identity processes relative to difference. We conclude that the new, emerging perspectives to understand differences point out a more complex vision of the different, beyond the paradigm of diversity. The hybrid, fluid, polysemic, albeit promising, field of difference thus emerges, which forms in the inter-places of the enunciations of different subjects and multiple sociocultural identities.

    Humans have always sought to imitate the human appearance, functions and intelligence. Human-like robots, which for many years have been a science fiction, are increasingly becoming an engineering reality resulting from the many advances in biologically inspired technologies. These biomimetic technologies include artificial intelligence, artificial vision and hearing as well as artificial muscles, also known as electroactive polymers (EAP). Robots, such as the vacuum cleaner Rumba and the robotic lawnmower, that don't have human shape, are already finding growing use in homes worldwide. As opposed to other human-made machines and devices, this technology raises also various questions and concerns and they need to be addressed as the technology advances. These include the need to prevent accidents, deliberate harm, or their use in crime. In this paper the state-of-the-art of the ultimate goal of biomimetics, the development of humanlike robots, the potentials and the challenges are reviewed.

    Teaching Robotics is about empowering students to create and configure robotics devices and program computers to nurture in students the skill sets necessary to play an active role in society. The robot in Figure 1 focuses on the design of scaffolds and physical assembly methods, coupled with a computer logic program to make that makes it move or behave in a very precise (remote controlled or autonomous) manner. This enables students to investigate, explore and refine the program to affect the robots. The Robotics approach takes into account the increasing popularity of Computer Science and the learning by doing (Schank, Berman, & Macpherson, 1999) approach to solve complex problems and use computers meaningfully in learning (Barron & Darling-Hammond, 2008; Jonassen, Howland, Marra, & Crismond, 2008).

  7. Survival of falling robots

    Cameron, Jonathan M.; Arkin, Ronald C.

    1992-01-01

    As mobile robots are used in more uncertain and dangerous environments, it will become important to design them so that they can survive falls. In this paper, we examine a number of mechanisms and strategies that animals use to withstand these potentially catastrophic events and extend them to the design of robots. A brief survey of several aspects of how common cats survive falls provides an understanding of the issues involved in preventing traumatic injury during a falling event. After outlining situations in which robots might fall, a number of factors affecting their survival are described. From this background, several robot design guidelines are derived. These include recommendations for the physical structure of the robot as well as requirements for the robot control architecture. A control architecture is proposed based on reactive control techniques and action-oriented perception that is geared to support this form of survival behavior.

    This manuscript describes a unique class of locomotive robot: A soft robot, composed exclusively of soft materials (elastomeric polymers), which is inspired by animals (e.g., squid, starfish, worms) that do not have hard internal skeletons. Soft lithography was used to fabricate a pneumatically actuated robot capable of sophisticated locomotion (e.g., fluid movement of limbs and multiple gaits). This robot is quadrupedal; it uses no sensors, only five actuators, and a simple pneumatic valving system that operates at low pressures (< 10 psi). A combination of crawling and undulation gaits allowed this robot to navigate a difficult obstacle. This demonstration illustrates an advantage of soft robotics: They are systems in which simple types of actuation produce complex motion.

    2014-11-01

    Robotic surgery was launched in Japan in 2000.In particular, the development of the da Vinci S Surgical System was a major breakthrough. It was introduced in Japan for the first time through our hospital in January 2009. Since then, the number of surgical robots used has been dramatically increasing, with up to approximately 160 robots all over the country. To date, we have performed more than 500 robotic surgeries, including 180 gastrectomies, at our hospital. Our data suggest that compared with the conventional laparoscopic approach, the use of the da Vinci Surgical System in minimally invasive gastrectomy for gastric cancer might improve short-term outcomes, particularly in terms of preventing postoperative local complications. Thus, we believe that use of surgical robots become increasingly beneficial for more extensive resections and operations that require more advanced skills, even though a couple of issues remain to be solved, such as long operative time, high cost, and limited experience and evidence. In this article, the current status and future perspectives regarding robotic gastrectomy for gastric cancer are presented based on our experience and a review of the literature. PMID:25434438

    Robots for use in assembly and other interactive tasks must be able to respond to both forces and velocity commands within their workspace. By considering a general six-joint robot it is shown that all such robots are limited in their ability to respond in orientation to feedback commands. It is also shown that it is simple to predict, if not to avoid, these regions of degeneracy in which the manipulator loses a degree of freedom.

    Full Text Available Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet syndrome. However, we emphasize that new instruments should be designed and further studies are needed to evaluate in vivo results.

Os desafios para investigação escolar das instituições, localidades e relações são enormes. Esse exercício didático é o alvo do presente texto, cujo objetivo é mostrar a preocupação e o avanço, de alguns estudiosos, na construção de uma 'teoria' das aulas de campo, aqui denominadas aulas em campo. A proposta corresponde à apresentação e discussão de certas abordagens específicas para esse tipo de aula. No entanto, esse cultivo não se realiza de forma contínua nem está no centro do planejamento da geografia escolar. Ele aparece como uma exceção contra a qual os autores aqui citados reagem, caracterizam limites e potencialidades e direcionam soluções. Para tanto, propõem seu resgate nas diversas formas de atividades externas ao espaço escolar: excursões, visitas, estudos do meio, turismo. A força pedagógica da aula em campo encontra-se, todavia, na capacidade da interação professor-aluno em apreender com o lugar-mundo e planejar-se no improviso, o que, na conclusão do artigo, aparece como defesa de uma postura estratégica da gestão do retorno à sala de aula. Chamada de autobiografia coletiva da aula anterior, o texto propõe ampliar a relevância das discussões sobre a experiência do campo para potencializar os conteúdos e métodos de aprendizagem, lembrando que a aula em campo é, tal qual inspiração artística, um vetor insubstituível de compreensão do espaço em nível escolar.The teaching of geography cultivates a link of identity with the exterior world: the field class.

    Human-robot interaction (HRI) is a discipline investigating the factors affecting the interactions between humans and robots. It is important to evaluate how the design of interfaces affect the human's ability to perform tasks effectively and efficiently when working with a robot. By understanding the effects of interface design on human performance, workload, and situation awareness, interfaces can be developed to appropriately support the human in performing tasks with minimal errors and with appropriate interaction time and effort. Thus, the results of research on human-robot interfaces have direct implications for the design of robotic systems. For efficient and effective remote navigation of a rover, a human operator needs to be aware of the robot's environment. However, during teleoperation, operators may get information about the environment only through a robot's front-mounted camera causing a keyhole effect. The keyhole effect reduces situation awareness which may manifest in navigation issues such as higher number of collisions, missing critical aspects of the environment, or reduced speed. One way to compensate for the keyhole effect and the ambiguities operators experience when they teleoperate a robot is adding multiple cameras and including the robot chassis in the camera view. Augmented reality, such as overlays, can also enhance the way a person sees objects in the environment or in camera views by making them more visible. Scenes can be augmented with integrated telemetry, procedures, or map information. Furthermore, the addition of an exocentric (i.e., third-person) field of view from a camera placed in the robot's environment may provide operators with the additional information needed to gain spatial awareness of the robot. Two research studies investigated possible mitigation approaches to address the keyhole effect: 1) combining the inclusion of the robot chassis in the camera view with augmented reality overlays, and 2) modifying the camera

    This report contains the results of a research effort on advanced robot locomotion. The majority of this work focuses on walking robots. Walking robot applications include delivery of special payloads to unique locations that require human locomotion to exo-skeleton human assistance applications. A walking robot could step over obstacles and move through narrow openings that a wheeled or tracked vehicle could not overcome. It could pick up and manipulate objects in ways that a standard robot gripper could not. Most importantly, a walking robot would be able to rapidly perform these tasks through an intuitive user interface that mimics natural human motion. The largest obstacle arises in emulating stability and balance control naturally present in humans but needed for bipedal locomotion in a robot. A tracked robot is bulky and limited, but a wide wheel base assures passive stability. Human bipedal motion is so common that it is taken for granted, but bipedal motion requires active balance and stability control for which the analysis is non-trivial. This report contains an extensive literature study on the state-of-the-art of legged robotics, and it additionally provides the analysis, simulation, and hardware verification of two variants of a proto-type leg design.

Com o toxóide tetánico precipitado pelo alúmen observaram que os níveis protetores surgiram já com a 2.ª dose. enquanto que com o toxóide fluido houve necessidade da 3.ª dose para serem atingidos níveis protetores na totalidade dos casos. A titulagem realizada após a 3.ª dose não mostrou diferenças significativas entre os títulos obtidos com 2 Lf do toxóide precipitado e os obtidos com 20 Lf do toxóide fluido, sendo porém, alcançados níveis menores com a dose de 10 Lf do toxóide fluido. Não observaram para efeitos graves com nenhum dos toxóides, sendo referido, contudo, manifestações dolorosas no local da aplicação do toxóide precipitado.

    Minimally invasive laparoscopic surgery has become to replace many of the open procedures in urology because of the obvious benefits in perioperative morbidity. However, because of the technical challenges and steep learning curve, the adoption of laparoscopy has been limited to only highly skilled laparoscopic surgeons. The introduction of the da Vinci surgical system (Intuitive Surgical Inc, Sunnyvale, Calif) has offered significant technical advantages over laparoscopic surgery. Because of the wide acceptance of robotic-assisted radical prostatectomy over the past decade, it has paved the way for urologists to tackle other complex operations, such as a radical cystectomy to decrease the morbidity of the operation. The goal of this article was to review the history and discuss the application and current status of the robot in both prostate and bladder cancer management. We present our technique of performing a robotic-assisted radical prostatectomy and the application of the robust prostate experience to robotic cystectomy. PMID:23528721

    Full Text Available Concretos refratários no sistema Al2O3-SiC-C vêm sendo utilizados principalmente no revestimento de canais de corrida de altos-fornos. A associação dessas matérias-primas tem elevado o desempenho dos concretos refratários frente às severas condições de trabalho, devido ao aumento da resistência ao choque térmico e ao ataque por escória e metal fundido. Apesar disso, o nível de conhecimento científico sobre a dispersão das partículas desse sistema multifásico é limitado. Neste trabalho, suspensões representativas da matriz de concretos refratários zero-cimento no sistema Al2O3-SiC-C foram preparadas para a avaliação da eficiência de aditivos na dispersão simultânea de diferentes matérias-primas, bem como para a análise do comportamento reológico da matriz em função do pH e teor de aditivo. Os ácidos poliacrílico e cítrico e um surfactante não iônico foram usados como dispersantes. Os valores de viscosidade aparente e tensão de escoamento obtidos foram usados para construir mapas de estabilidade da matriz. Medidas de pH e fluidez de concretos preparados com diferentes teores de aditivo mostraram que as condições iniciais de pH não foram correspondentes à região ótima de dispersão estabelecida pelos mapas de estabilidade. O uso de altos teores de ácido cítrico, bem como, o deslocamento do pH do concreto na direção da região ótima de dispersão foram eficientes para otimizar a sua fluidez.Refractory castables in the Al2O3-SiC-C system have been used mainly as linings for blast furnace runners.

La forma de interacción es fundamental ya que acciones negativas dirigidas en esta etapa son perjudiciales en su conducta y su personalidad, el sujeto en esta etapa es semejante a una esponja que va absorbiendo todo los estímulos a su alrededor y en un nivel psicológico todas las acciones que el niño pueda apreciar, producirán que en su inconsciente se genere un saber que más tarde será manifestado con diferentes formas de actuar del sujeto. Si se tiene una infancia donde se le produzca sufrimiento, entonces estos sufrimientos quebrantaran la cognición del mismo, y en su inconsciente se generara un sentimiento negativo, o ya bien un trauma o secuela, producida por un daño psicológico que por daños sicológico entendemos que el sujeto ha sido víctima de abusos y maltratos; estos maltratos pueden ser de carácter físico (golpes, torturas, quemaduras, es decir toda lesión producida en su fisiología y moral (humillaciones, insultos, etcétera que estos a su vez generan un daño psicológico, encontrando secuelas tales como la inseguridad, inestabilidad, agresividad y trastornos que modifiquen la personalidad, por ende el sujeto presenta una conducta antisocial, con posibilidades de convertirse en un criminal.

Amostra foi feita com até 109 enfermeiras. Os resultados principais indicaram que a maioria considerou o treinamento acadêmico insuficiente para apoiar este aspecto dos cuidados; não receberam treinamento local na avaliação de dor ou intervenções para aliviá-la; a proporção do pessoal é inadequada assim como a disponibilidade de instruções institucionais para melhorar a qualidade da analgesia. Concluiu-se que as enfermeiras valorizam a avaliação e intervenção para o alívio de dor em crianças, mas descrevem os aspectos que comprometem a prática: falta de colaboração, falta da definição de processos, falta de educação formal e contínua e de infraestrutura. Estes aspectos comprometem a implementação das evidências científicas capazes de melhorar os aspectos práticos de analgesia nas crianças sob cuidados intensivos.

    The functions of soft robotics are intimately tied to their form-channels and voids defined by an elastomeric superstructure that reversibly stores and releases mechanical energy to change shape, grip objects, and achieve complex motions. Here, we demonstrate that covalent polymer mechanochemistry provides a viable mechanism to convert the same mechanical potential energy used for actuation in soft robots into a mechanochromic, covalent chemical response. A bis-alkene functionalized spiropyran (SP) mechanophore is cured into a molded poly(dimethylsiloxane) (PDMS) soft robot walker and gripper. The stresses and strains necessary for SP activation are compatible with soft robot function. The color change associated with actuation suggests opportunities for not only new color changing or camouflaging strategies, but also the possibility for simultaneous activation of latent chemistry (e.g., release of small molecules, change in mechanical properties, activation of catalysts, etc.) in soft robots. In addition, mechanochromic stress mapping in a functional robotic device might provide a useful design and optimization tool, revealing spatial and temporal force evolution within the robot in a way that might be coupled to autonomous feedback loops that allow the robot to regulate its own activity. The demonstration motivates the simultaneous development of new combinations of mechanophores, materials, and soft, active devices for enhanced functionality. PMID:26390078

    Modern technologies play a very important role in our lives. It is hard to imagine how people can get along without personal computers, and companies - without powerful computer centers. Nowadays, many devices make modern medicine more effective. Medicine is developing constantly, so introduction of robots in this sector is a very promising activity. Advances in technology have influenced medicine greatly. Robotic surgery is now actively developing worldwide. Scientists have been carrying out research and practical attempts to create robotic surgeons for more than 20 years, since the mid-80s of the last century. Robotic assistants play an important role in modern medicine. This industry is new enough and is at the early stage of development; despite this, some developments already have worldwide application; they function successfully and bring invaluable help to employees of medical institutions. Today, doctors can perform operations that seemed impossible a few years ago. Such progress in medicine is due to many factors. First, modern operating rooms are equipped with up-to-date equipment, allowing doctors to make operations more accurately and with less risk to the patient. Second, technology has enabled to improve the quality of doctors' training. Various types of robots exist now: assistants, military robots, space, household and medical, of course. Further, we should make a detailed analysis of existing types of robots and their application. The purpose of the article is to illustrate the most popular types of robots used in medicine.

    Frick, A C; Falcone, T

    2009-06-01

    Robotic surgery has evolved from an investigational surgical approach to a clinically useful adjunct in multiple surgical specialties over the past decade. Advocates of robotic-assisted gynecologic surgery revere the system's wristed instrumentation, ergonomic positioning, and three-dimensional high-definition vision system as significant improvements over laparoscopic equipment's four degrees of freedom and two-dimensional laparoscope that demand the surgeon stand throughout a procedure. The cost, lack of haptic feedback, and the bulky size of the equipment make robotics less attractive to others. Studies evaluating outcomes in robotic-assisted gynecologic surgery are limited. Multiple small retrospective studies demonstrate the safety and feasibility of robotic hysterectomy. With increased surgeon experience, operative times are similar to, or shorter than, laparoscopic cases. Robotic assistance can facilitate suturing in laparoscopic myomectomies, and is associated with decreased blood loss and a shorter hospital stay, although may require longer operative times. Robotic assistance has also been applied to multiple procedures in the subspecialties of infertility, urogynecology and gynecologic oncology with good success and relatively low morbidity. However, further research is warranted to better evaluate the relative benefits and costs of robotic assisted gynecologic surgery.

    Honda has been doing research on robotics since 1986 with a focus upon bipedal walking technology. The research started with straight and static walking of the first prototype two-legged robot. Now, the continuous transition from walking in a straight line to making a turn has been achieved with the latest humanoid robot ASIMO. ASIMO is the most advanced robot of Honda so far in the mechanism and the control system. ASIMO's configuration allows it to operate freely in the human living space. It could be of practical help to humans with its ability of five-finger arms as well as its walking function. The target of further development of ASIMO is to develop a robot to improve life in human society. Much development work will be continued both mechanically and electronically, staying true to Honda's 'challenging spirit'.

  12. Quantum Robots and Environments

    CERN Document Server

    Benioff, P

    1998-01-01

    Quantum robots and their interactions with environments of quantum systems are described and their study justified. A quantum robot is a mobile quantum system that includes a quantum computer and needed ancillary systems on board. Quantum robots carry out tasks whose goals include specified changes in the state of the environment or carrying out measurements on the environment. Each task is a sequence of alternating computation and action phases. Computation phase activities include determination of the action to be carried out in the next phase and possible recording of information on neighborhood environmental system states.

    2016-01-01

    Robotic surgeries have developed in the general thoracic field over the past decade, and publications on robotic surgery outcomes have accumulated. However, controversy remains about the application of robotic surgery, with a lack of well-established evidence. Robotic surgery has several advantages such as natural movement of the surgeon’s hands when manipulating the robotic arms and instruments controlled by computer-assisted systems. Most studies have reported the feasibility and safety of robotic surgery based on acceptable morbidity and mortality compared to open or video-assisted thoracic surgery (VATS). Furthermore, there are accumulated data to indicate longer operation times and shorter hospital stay in robotic surgery. However, randomized controlled trials between robotic and open or VATS procedures are needed to clarify the advantage of robotic surgery. In this review, we focused the literature about robotic surgery used to treat lung cancer and mediastinal tumor. PMID:26822625

    Full Text Available Fome, desnutrição e pobreza são problemas de natureza, dimensão e tendências muito distintas no Brasil, comportando soluções com escala, investimentos e conteúdos distintos. Ações governamentais de combate à pobreza certamente merecem máxima prioridade, justificam grandes investimentos e devem perseguir essencialmente o aumento da renda dos mais pobres. Ações que resultem em maior crescimento econômico com melhor distribuição de renda e que levem à reativação da economia, à criação de empregos e ao aprofundamento da reforma agrária são vistas como soluções consensuais no país. Mais recentemente, o mesmo acordo parece existir quanto a programas governamentais de transferência direta de renda acoplados a contrapartidas das famílias beneficiárias, seja com relação à manutenção das crianças nas escolas (bolsa-escola, seja com relação a controles preventivos de saúde (bolsa alimentação. Ações que combatam eficientemente a pobreza serão obviamente de enorme valia para a luta contra a desnutrição. Entretanto, a experiência nacional e internacional mostra que a intensificação dos investimentos em educação, saneamento do meio e cuidados básicos de saúde será essencial para se alcançar a erradicação da desnutrição. A luta contra a fome, ou ao que resta desse problema no país, igualmente se beneficiará do combate à pobreza. Contudo, as evidências indicam que ações específicas de combate à fome, em particular ações de distribuição de alimentos (diretamente ou através de créditos ou cupons, deveriam ser empregadas no Brasil de modo limitado e apenas em condições excepcionais e devidamente justificadas. A expansão desmedida de ações de distribuição de alimentos, ao contrário do que talvez indiquem o senso comum e a indignação justificada diante de uma sociedade tão injusta como a brasileira, implicaria apenas consumir recursos que poderiam faltar para ações sociais melhor

    Computer-integrated robotic surgery systems appeared more than twenty years ago and since then hundreds of different prototypes have been developed. Only a fraction of them have been commercialized, mostly to support neurosurgical and orthopaedic procedures.Unquestionably, the most successful one is the da Vinci surgical system, primarily deployed in urology and general laparoscopic surgery. It is developed and marketed by Intuitive Surgical Inc. (Sunnyvale, CA, USA), the only profitable company of the segment. The da Vinci made robotic surgery is known and acknowledged throughout the world, and the great results delivered convinced most of the former critics of the technology. Success derived from the well chosen business development strategy, proficiency of the developers, appropriate timing and a huge pot of luck. This article presents the most important features of the da Vinci system, the history of development along with its medical, economical and financial aspects, and seeks the answer why this particular system became successful.

  8. Design and optimization of a brachytherapy robot

    Meltsner, Michael A.

    Trans-rectal ultrasound guided (TRUS) low dose rate (LDR) interstitial brachytherapy has become a popular procedure for the treatment of prostate cancer, the most common type of non-skin cancer among men. The current TRUS technique of LDR implantation may result in less than ideal coverage of the tumor with increased risk of negative response such as rectal toxicity and urinary retention. This technique is limited by the skill of the physician performing the implant, the accuracy of needle localization, and the inherent weaknesses of the procedure itself. The treatment may require 100 or more sources and 25 needles, compounding the inaccuracy of the needle localization procedure. A robot designed for prostate brachytherapy may increase the accuracy of needle placement while minimizing the effect of physician technique in the TRUS procedure. Furthermore, a robot may improve associated toxicities by utilizing angled insertions and freeing implantations from constraints applied by the 0.5 cm-spaced template used in the TRUS method. Within our group, Lin et al. have designed a new type of LDR source. The "directional" source is a seed designed to be partially shielded. Thus, a directional, or anisotropic, source does not emit radiation in all directions. The source can be oriented to irradiate cancerous tissues while sparing normal ones. This type of source necessitates a new, highly accurate method for localization in 6 degrees of freedom. A robot is the best way to accomplish this task accurately. The following presentation of work describes the invention and optimization of a new prostate brachytherapy robot that fulfills these goals. Furthermore, some research has been dedicated to the use of the robot to perform needle insertion tasks (brachytherapy, biopsy, RF ablation, etc.) in nearly any other soft tissue in the body. This can be accomplished with the robot combined with automatic, magnetic tracking.

    Computer-driven robots and medical imaging technology may soon enable surgeons to plan and execute intricate procedures with unprecedented precision. Our experience in introducing a robotic system for use in an active role in cementless total hip replacement surgery has convinced us that the marriage of these two technologies-robotics and medical imaging-is likely to change the way many types of surgical procedures are performed. The ability to link an image-based preoperative plan with its surgical execution by a robot may be the key to improved outcomes. Research and development of robotic systems for a wide variety of medical applications is underway at a number of prestigious institutions. Grenoble University has developed the IGOR (Imaged Guided Operating Robot) system. This six-axis robot has performed more than 400 interventions, acting as a positioner for brain surgery in both biopsy and therapeutic procedures. AlephMed and Digital are currently assisting the developers in integrating image analysis into the system. Future development plans include an application for spinal surgery. PMID:25951597

    Our long-term goal is to develop autonomous robotic systems that have the cognitive abilities of humans, including communication, coordination, adapting to novel situations, and learning through experience. Our approach rests on the recent integration of the Soar cognitive architecture with both virtual and physical robotic systems. Soar has been used to develop a wide variety of knowledge-rich agents for complex virtual environments, including distributed training environments and interactive computer games. For development and testing in robotic virtual environments, Soar interfaces to a variety of robotic simulators and a simple mobile robot. We have recently made significant extensions to Soar that add new memories and new non-symbolic reasoning to Soar's original symbolic processing, which should significantly improve Soar abilities for control of robots. These extensions include episodic memory, semantic memory, reinforcement learning, and mental imagery. Episodic memory and semantic memory support the learning and recalling of prior events and situations as well as facts about the world. Reinforcement learning provides the ability of the system to tune its procedural knowledge - knowledge about how to do things. Mental imagery supports the use of diagrammatic and visual representations that are critical to support spatial reasoning. We speculate on the future of unmanned systems and the need for cognitive robotics to support dynamic instruction and taskability.

    2000-10-01

    The paper investigates how the psychological notion of comfort can be useful in the design of robotic systems. A review of the existing study of human comfort, especially regarding its presence in infants, is conducted with the goal being to determine the relevant characteristics for mapping it onto the robotics domain. Focus is place on the identification of the salient features in the environment that affect the comfort level. Factors involved include current state familiarity, working conditions, the amount and location of available resources, etc. As part of our newly developed comfort function theory, the notion of an object as a psychological attachment for a robot is also introduced, as espoused in Bowlby's theory of attachment. The output space of the comfort function and its dependency on the comfort level are analyzed. The results of the derivation of this comfort function are then presented in terms of the impact they have on robotic behavior. Justification for the use of the comfort function are then presented in terms of the impact they have on robotic behavior. Justification for the use of the comfort function in the domain of robotics is presented with relevance for real-world operations. Also, a transformation of the theoretical discussion into a mathematical framework suitable for implementation within a behavior-based control system is presented. The paper concludes with results of simulation studies and real robot experiments using the derived comfort function.

    2008-04-01

    As unmanned systems become more commonplace in military, police, and other security forces, they are tasked to perform missions that the original hardware was not designed for. Current military robots are built for rough outdoor conditions and have strong inflexible manipulators designed to handle a wide range of operations. However, these manipulators are not well suited for some essential indoor tasks, including opening doors. This is a complicated kinematic task that places prohibitively difficult control challenges on the robot and the operator. Honeybee and iRobot have designed a modular door-breaching manipulator that mechanically simplifies the demands upon operator and robot. The manipulator connects to the existing robotic arm of the iRobot PackBot EOD. The gripper is optimized for grasping a variety of door knobs, levers, and car-door handles. It works in conjunction with a compliant wrist and magnetic lock-out mechanism that allows the wrist to remain rigid until the gripper has a firm grasp of the handle and then bend with its rotation and the swing of the door. Once the door is unlatched, the operator simply drives the robot through the doorway while the wrist compensates for the complex, multiple degree-of-freedom motion of the door. Once in the doorway the operator releases the handle, the wrist pops back into place, and the robot is ready for the next door. The new manipulator dramatically improves a robot's ability to non-destructively breach doors and perform an inspection of a room's content, a capability that was previously out of reach of unmanned systems.

    In recent years, transoral robotic surgery has been introduced as an efficient and a reliable method for excision of selected oral cavity, tongue base, and supraglottic tumors in otolaryngology. In this case report, a 39-year-old woman with a history of hoarseness and dysphagia for approximately 6 months is presented. The patient was diagnosed with atypical carcinoid tumor on the laryngeal aspect of the epiglottis, and excision of the tumor was performed through transoral robotic surgery using the robotic da Vinci surgical system, a 0-degree three-dimensional endoscope, 5-mm microinstruments compatible with the da Vinci robot, and a Feyh-Kastenbauer/Weinstein-O'Malley retractor. The mass was removed completely, and no complications occurred. The patient recovered without a need for tracheotomy. Findings of the 1-year clinical follow-up revealed no locoregional recurrence or distant metastasis. This case shows, once again, that transoral robotic surgery could be used safely and effectively regardless of pathologic diagnosis in the supraglottic region tumors. PMID:24220389

    Full Text Available A novel concept of media education called “robot literacy” is proposed. Here, robot literacy refers to the means of forming an appropriate relationship with intelligent robots. It can be considered a kind of media literacy. People who were born after the Internet age can be considered “digital natives” who have new morals and values and behave differently than previous generations in Internet societies. This can cause various problems among different generations. Thus, the necessity of media literacy education is increasing. Internet technologies, as well as robotics technologies are growing rapidly, and people who are born after the “home robot age,” whom the author calls “robot natives,” will be expected to have a certain degree of “robot literacy.” In this paper, the concept of robot literacy is defined and an approach to robot literacy education is discussed.

    Full Text Available The remarkable advances of robotics in the last fifty years, which represent an incredible wealth of knowledge, are based on the fundamental assumption that robots are chains of rigid links. The use of soft materials in robotics, driven not only by new scientific paradigms (biomimetics, morphological computation, and others, but also by many applications (biomedical, service, rescue robots, and many more, is going to overcome these basic assumptions and makes the well-known theories and techniques poorly applicable, opening new perspectives for robot design and control.The current examples of soft robots represent a variety of solutions for actuation, and control. Though very first steps, they have the potential for a radical technological change. Soft robotics is not just a new direction of technological development, but a novel approach to robotics, unhinging its fundamentals, with the potential to produce a new generation of robots, in the support of humans in our natural environments.

    Low intensity GaAlAs ({lambda}=830 nm) laser irradiation effects on oral traumatic ulceration were evaluated. For this purpose, twenty patients presenting orthodontic appliance - induced oral traumatic ulceration were randomly distributed in two groups. Patients in group 1 were submitted to the irradiation procedure and group 2 was the control one. The irradiation parameters employed were the following: wavelength 830 nm, one single application of 4 J/cm{sup 2}, punctual in the contact mode and 30 mW power. The control group received the conventional treatment, consisting on topical application of Triancinolon based ointment four times a day. For both groups the agent responsible for the trauma was removed or covered with utility wax whenever removal was impossible. The results were evaluated concerning the wounds size reduction and pain relief. The time of laser irradiation was considered the starting time (time zero) and analysis were done 24 hours, 48 hours and seven days after that. The statistical analysis showed an acceleration in the healing process as well accentuated pain reduction for the irradiated group compared to the control one. These evidences allows us to indicate this protocol of one single application of 4 J/cm{sup 2} as therapy when patients with oral traumatic ulceration can not attend several sessions for a multiple application procedure.

    The corrosion behavior of the CuAlNi shape memory alloy in oil landfield produced groundwater was investigated with polarization curve and mass loss measurements, the latter carried out by immersion in laboratory and field tests. The physico-chemical analysis of five types of oil landfield produced groundwater showed the presence of H{sub 2}S and CO{sub 2}, high salinity, chloride, sulfide and iron ions and relatively neutral pH. The results from electrochemical tests in aerated produced groundwater, in the range of salinity encountered, suggested that the corrosion rate increases at higher saline concentrations. The results from field tests with corrosion test specimens showed a moderate to severe corrosion rate and suggested, in the other hand, that corrosion rates were influenced not only by salinity and oxidizing ions present in the flowing fluid, but also by solid materials in suspension, the fluid's temperature, and the flow velocity. This research is part of a major project which aims to develop couplings for landfield produced fluid transportation pipe connections without welded nor threaded joints. (author)

    2009-05-01

    Limited autonomous behaviors are fast becoming a critical capability in the field of robotics as robotic applications are used in more complicated and interactive environments. As additional sensory capabilities are added to robotic platforms, sensor fusion to enhance and facilitate autonomous behavior becomes increasingly important. Using biology as a model, the equivalent of a vestibular system needs to be created in order to orient the system within its environment and allow multi-modal sensor fusion. In mammals, the vestibular system plays a central role in physiological homeostasis and sensory information integration (Fuller et al, Neuroscience 129 (2004) 461-471). At the level of the Superior Colliculus in the brain, there is multimodal sensory integration across visual, auditory, somatosensory, and vestibular inputs (Wallace et al, J Neurophysiol 80 (1998) 1006-1010), with the vestibular component contributing a strong reference frame gating input. Using a simple model for the deep layers of the Superior Colliculus, an off-the-shelf 3-axis solid state gyroscope and accelerometer was used as the equivalent representation of the vestibular system. The acceleration and rotational measurements are used to determine the relationship between a local reference frame of a robotic platform (an iRobot Packbot®) and the inertial reference frame (the outside world), with the simulated vestibular input tightly coupled with the acoustic and optical inputs. Field testing of the robotic platform using acoustics to cue optical sensors coupled through a biomimetic vestibular model for "slew to cue" gunfire detection have shown great promise.

    Robot platforms, methods, and computer media are disclosed. The robot platform includes perceptors, locomotors, and a system controller, which executes instructions for a robot to follow a target in its environment. The method includes receiving a target bearing and sensing whether the robot is blocked front. If the robot is blocked in front, then the robot's motion is adjusted to avoid the nearest obstacle in front. If the robot is not blocked in front, then the method senses whether the robot is blocked toward the target bearing and if so, sets the rotational direction opposite from the target bearing, and adjusts the rotational velocity and translational velocity. If the robot is not blocked toward the target bearing, then the rotational velocity is adjusted proportional to an angle of the target bearing and the translational velocity is adjusted proportional to a distance to the nearest obstacle in front.

    Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes. Although robotic surgeries have become the gold standard for a number of procedures, the research in colorectal surgery is not definitive and more work needs to be done to prove its safety and efficacy to both surgeons and patients.

    A quantum robot is a mobile quantum system including an on bord quantum computer and ancillary systems, that interact with an environment of quantum systems. Quantum robots carry out tasks whose goals include carrying out measurements and physical experiments on the environment. Environments considered so far in the literature: oracles, data bases, and quantum registers, are shown to be special cases of environments considered here. It is noted that quantum robots should include a quantum computer and cannot be simply a multistate head. A model is discussed in which each task, as a sequence of computation and action phases, is described by a unitary step operator. Overall system dynamics is described in terms of a Feynman sum over paths of completed computation and action phases. A simple task example, measuring the distance between the quantum robot and a particle on a 1D space lattice, with quantum phase path and time duration dispersion present, is analyzed.

    In nature, nanometer-scale molecular motors are used to generate force within cells for diverse processes from transcription and transport to muscle contraction. This adaptability and scalability across wide temporal, spatial, and force regimes have spurred the development of biological soft robotic systems that seek to mimic and extend these capabilities. This review describes how molecular motors are hierarchically organized into larger-scale structures in order to provide a basic understanding of how these systems work in nature and the complexity and functionality we hope to replicate in biological soft robotics. These span the subcellular scale to macroscale, and this article focuses on the integration of biological components with synthetic materials, coupled with bioinspired robotic design. Key examples include nanoscale molecular motor-powered actuators, microscale bacteria-controlled devices, and macroscale muscle-powered robots that grasp, walk, and swim. Finally, the current challenges and future opportunities in the field are addressed.

    In the attempt to build adaptive and intelligent machines, roboticists have looked at neuroscience for more than half a century as a source of inspiration for perception and control. More recently, neuroscientists have resorted to robots for testing hypotheses and validating models of biological nervous systems. Here, we give an overview of the work at the intersection of robotics and neuroscience and highlight the most promising approaches and areas where interactions between the two fields have generated significant new insights. We articulate the work in three sections, invertebrate, vertebrate and primate neuroscience. We argue that robots generate valuable insight into the function of nervous systems, which is intimately linked to behaviour and embodiment, and that brain-inspired algorithms and devices give robots life-like capabilities.

  17. Visual Measurement of Suture Strain for Robotic Surgery

    Directory of Open Access Journals (Sweden)

    John Martell

    2011-01-01

    Full Text Available Minimally invasive surgical procedures offer advantages of smaller incisions, decreased hospital length of stay, and rapid postoperative recovery to the patient. Surgical robots improve access and visualization intraoperatively and have expanded the indications for minimally invasive procedures. A limitation of the DaVinci surgical robot is a lack of sensory feedback to the operative surgeon. Experienced robotic surgeons use visual interpretation of tissue and suture deformation as a surrogate for tactile feedback. A difficulty encountered during robotic surgery is maintaining adequate suture tension while tying knots or following a running anastomotic suture. Displaying suture strain in real time has potential to decrease the learning curve and improve the performance and safety of robotic surgical procedures. Conventional strain measurement methods involve installation of complex sensors on the robotic instruments. This paper presents a noninvasive video processing-based method to determine strain in surgical sutures. The method accurately calculates strain in suture by processing video from the existing surgical camera, making implementation uncomplicated. The video analysis method was developed and validated using video of suture strain standards on a servohydraulic testing system. The video-based suture strain algorithm is shown capable of measuring suture strains of 0.2% with subpixel resolution and proven reliability under various conditions.

    2014-07-01

    Full Text Available Robotic swarms that take inspiration from nature are becoming a fascinating topic for multi-robot researchers. The aim is to control a large number of simple robots in order to solve common complex tasks. Due to the hardware complexities and cost of robot platforms, current research in swarm robotics is mostly performed by simulation software. The simulation of large numbers of these robots in robotic swarm applications is extremely complex and often inaccurate due to the poor modelling of external conditions. In this paper, we present the design of a low-cost, open-platform, autonomous micro-robot (Colias for robotic swarm applications. Colias employs a circular platform with a diameter of 4 cm. It has a maximum speed of 35 cm/s which enables it to be used in swarm scenarios very quickly over large arenas. Long-range infrared modules with an adjustable output power allow the robot to communicate with its direct neighbours at a range of 0.5 cm to 2 m. Colias has been designed as a complete platform with supporting software development tools for robotics education and research. It has been tested in both individual and swarm scenarios, and the observed results demonstrate its feasibility for use as a micro-sized mobile robot and as a low-cost platform for robot swarm applications.

    Full Text Available As alças de retração ortodôntica são comumente empregadas em sistema Edgewise por meio de uma abordagem seccional (ex.: retração de caninos ou por meio de uma abordagem segmentada (ex.: retração dos dentes anteriores em conjunto. Estas alças podem modular a demanda de ancoragem, dependendo dos objetivos impostos pelo plano de tratamento. Neste trabalho são discutidas as propriedades mecânicas relacionadas ao projeto de alças de retração ortodôntica, o sistema de forças decorrente de sua conformação geométrica e ativação, e os métodos empregados para testá-las. Dentre as técnicas utilizadas na análise de uma alça, o Método dos Elementos Finitos (MEF merece destaque. Embora seja baseado em modelos matemáticos, é uma ferramenta eficaz e não onerosa para a simulação computacional de um protótipo, podendo-se assim avaliá-lo antes de sua construção física. Já os métodos experimentais se aproximam mais da condição real, porém com custo mais elevado. A utilização em diferentes estágios de ambos os métodos é aconselhável para um melhor desenvolvimento e caracterização dos protótipos.Retraction springs are commonly used in Edgewise mechanics in a sectional (e.g. canine retraction or in a segmental approach (e.g. "en masse" anterior retraction. These springs can modulate the anchorage needs depending on the treatment plan objectives. In this work it is discussed the mechanical properties related to the spring’s design, the force system originated by their geometric shape and activation, and the methods used to test them. Among the techniques used to analyze a retraction spring, it can be pointed out the Finite Element Method (FEM. Nevertheless the FEM is based on mathematical models, it is an efficient non-onerous way for computational simulation of a prototype, so it can be evaluated before its physical construction. On the other hand, the experimental methods are closer to real conditions, but they

    2013-11-01

    We study multi-robot caravanning, which is loosely defined as the problem of a heterogeneous team of robots visiting specific areas of an environment (waypoints) as a group. After formally defining this problem, we propose a novel solution that requires minimal communication and scales with the number of waypoints and robots. Our approach restricts explicit communication and coordination to occur only when robots reach waypoints, and relies on implicit coordination when moving between a given pair of waypoints. At the heart of our algorithm is the use of leader election to efficiently exploit the unique environmental knowledge available to each robot in order to plan paths for the group, which makes it general enough to work with robots that have heterogeneous representations of the environment. We implement our approach both in simulation and on a physical platform, and characterize the performance of the approach under various scenarios. We demonstrate that our approach can successfully be used to combine the planning capabilities of different agents. © 2013 IEEE.

    It is man’s ongoing hope that a machine could somehow adapt to its environment by reorganizing itself. This is what the notion of self-organizing robots is based on. The theme of this book is to examine the feasibility of creating such robots within the limitations of current mechanical engineering. The topics comprise the following aspects of such a pursuit: the philosophy of design of self-organizing mechanical systems; self-organization in biological systems; the history of self-organizing mechanical systems; a case study of a self-assembling/self-repairing system as an autonomous distributed system; a self-organizing robot that can create its own shape and robotic motion; implementation and instrumentation of self-organizing robots; and the future of self-organizing robots. All topics are illustrated with many up-to-date examples, including those from the authors’ own work. The book does not require advanced knowledge of mathematics to be understood, and will be of great benefit to students in the rob...

A ênfase recai sobre a avaliação da responsabilidade ética da organização, à luz da rearticulação radical dos conceitos de ética, responsabilidade e subjetividade proposta por Emmanuel Levinas. Buscam-se as implicações dessa decisão em termos das conseqüências que ela permitiu - a saber, o genocídio ruandês, o prolongamento da violência possibilitado pela Operação Turquesa e a reorganização do movimento genocida nos campos de refugiados. Além disso, debruça-se sobre um tema mais profundo, que subjaz as condições permissivas dessas trágicas conseqüências: a dominação do princípio do Estado-territorial-soberano na imaginação política contemporânea. As rijas fronteiras entre dentro/fora, Estado/campo de refugiados, doméstico/internacional derivadas desse princípio impuseram também uma compartimentalização na seara da formulação de políticas para lidar com a crise humanitária que se seguiu ao genocídio. Essa forma fragmentada de lidar com um problema complexo e multifacetado, por sua vez, resultou em políticas que distorceram as prioridades, minaram a efetividade dos programas de assistência e alienaram o novo governo instalado.Drawing on a post-modern/post-structuralist approach in International Relations, this article aims to make an analysis of the UN's decision taken in April 21, 1994 about the establishment of Unamir as a response to the violence in Rwanda.

    Full Text Available A teoria econômica moderna foi além do "fundamentalismo do capital". Nas palavras de Hoff e Stiglitz (2001, p. 389, "o desenvolvimento não é mais visto primariamente como um processo de acúmulo de capital, mas antes como um processo de mudança organizacional". Essa percepção possibilitou uma "virada institucional" na teoria do desenvolvimento ao enfatizar o papel de idéias e das instituições enquanto determinantes das possibilidades para o acúmulo de capital, ao invés do oposto. Tanto a "nova teoria do crescimento" quanto o "novo institucionalismo" de Douglass North são exemplos dessa virada institucional. Infelizmente, a "virada institucional" tem sido utilizada de modo perverso por formadores de políticas globais. A visão globalmente dominante é a de que, por serem as instituições tão importantes, por conseguinte, um planejamento institucional baseado em versões idealizadas de instituições anglo-americanas deve ser uniformemente imposto aos países ao Sul do globo para que se desenvolvam. De forma não surpreendente, essa visão falhou na prática. Perspectivas alternativas propostas por Rodrik e Sen defendem que o desenvolvimento tem poucas possibilidades de ter êxito a menos que a mudança institucional esteja alicerçada na tomada de decisões local. Essa é a visão explorada neste trabalho.

Cerâmicas biomórficas são obtidas por meio do processo de biomodelagem, que consiste na reprodução ao nível micrométrico da estrutura natural do material de partida. Neste trabalho, os materiais ligninocelulósicos utilizados como material de partida foram fibras de sisal, ratam e pinheiro. Estes foram convertidos por pirólise em pré-formas de carbono. Subseqüentemente, essas pré-formas foram infiltradas com alumínio gasoso em temperaturas que variaram de 1400 ºC a 1600 ºC sob vácuo, obtendo-se assim carbeto de alumínio (Al4C3. Por ser um material frágil e de rápida decomposição, O Al4C3 foi rapidamente oxidado a 1600 ºC para sua conversão total em fibras de Al2O3 biomórfica.

    The search for life and its study is known as astrobiology. Conducting that search on other planets in our Solar System is a major goal of NASA and other space agencies, and a driving passion of the community of scientists and engineers around the world. We practice for that search in many ways, from exploring and studying extreme environments on Earth, to developing robots to go to other planets and help us look for any possible life that may be there or may have been there in the past. The unique challenges of space exploration make collaborations between robots and humans essential. The products of those collaborations will be novel and driven by the features of wholly new environments. For space and planetary environments that are intolerable for humans or where humans present an unacceptable risk to possible biologically sensitive sites, autonomous robots or telepresence offer excellent choices. The search for life signs on Mars fits within this category, especially in advance of human landed missions there, but also as assistants and tools once humans reach the Red Planet. For planetary destinations where we do not envision humans ever going in person, like bitterly cold icy moons, or ocean worlds with thick ice roofs that essentially make them planetary-sized ice caves, we will rely on robots alone to visit those environments for us and enable us to explore and understand any life that we may find there. Current generation robots are not quite ready for some of the tasks that we need them to do, so there are many opportunities for roboticists of the future to advance novel types of mobility, autonomy, and bio-inspired robotic designs to help us accomplish our astrobiological goals. We see an exciting partnership between robotics and astrobiology continually strengthening as we jointly pursue the quest to find extraterrestrial life.

  6. Exploiting Child-Robot Aesthetic Interaction for a Social Robot

    Directory of Open Access Journals (Sweden)

    Jae-Joon Lee

    2012-09-01

    Full Text Available A social robot interacts and communicates with humans by using the embodied knowledge gained from interactions with its social environment. In recent years, emotion has emerged as a popular concept for designing social robots. Several studies on social robots reported an increase in robot sociability through emotional imitative interactions between the robot and humans. In this paper conventional emotional interactions are extended by exploiting the aesthetic theories that the sociability of a social robot can be markedly enhanced through aesthetic imitative interactions such as “playful acts”. We applied these aesthetic interactions to child‐robot interaction. Children imitate the emotional behaviours of a robot through aesthetic interactions; they play with the robot by mimicking its emotional facial expressions. From the tests, we see that aesthetic judgment is more influential than emotions in playful interactions between children and the robot; the aesthetic imitative interactions would reinforce the positive social relationships of children and enhance their social adaptability. To the best of our knowledge, this is the first social robot study to investigate child‐robot interaction on the basis of aesthetics.

    2014-07-01

    We seek to provide a background of the current state of pediatric urologic surgery including a brief history, procedural outcomes, cost considerations, future directions, and the state of robotic surgery in India. Pediatric robotic urology has been shown to be safe and effective in cases ranging from pyeloplasty to bladder augmentation with continent urinary diversion. Complication rates are in line with other methods of performing the same procedures. The cost of robotic surgery continues to decrease, but setting up pediatric robotic urology programs can be costly in terms of both monetary investment and the training of robotic surgeons. The future directions of robot surgery include instrument and system refinements, augmented reality and haptics, and telesurgery. Given the large number of children in India, there is huge potential for growth of pediatric robotic urology in India. Pediatric robotic urologic surgery has been established as safe and effective, and it will be an important tool in the future of pediatric urologic surgery worldwide. PMID:25197187

  16. Lessons of nuclear robot history

    International Nuclear Information System (INIS)

    Severe accidents occurred at Fukushima Daiichi Nuclear Power Station stirred up people's great expectation of nuclear robot's deployment. However unexpected nuclear disaster, especially rupture of reactor building caused by core meltdown and hydrogen explosion, made it quite difficult to introduce nuclear robot under high radiation environment to cease accidents and dispose damaged reactor. Robotics Society of Japan (RSJ) set up committee to look back upon lessons learned from 50 year's past experience of nuclear robot development and summarized 'Lessons of nuclear robot history', which was shown on the home page website of RSJ. This article outlined it with personal comment. History of nuclear robot developed for inspection and maintenance at normal operation and for specific required response at nuclear accidents was reviewed with many examples at home and abroad for TMI, Chernobyl and JCO accidents. Present state of Fukushima accident response robot's introduction and development was also described with some comments on nuclear robot development from academia based on lessons. (T. Tanaka)

    Full Text Available Introduction The purpose of this video is to demonstrate the use of the robot to perform a transmesocolonic pyelolithotomy of a horseshoe kidney. Materials and Methods A 35-year old female presented with vague abdominal pain. CT scan imaging revealed the presence of a left horseshoe kidney with multiple pelvicalyceal stones. The patient was positioned in the supine position. A total of 4 ports were introduced. A 3-arm da Vinci robotic surgical system was docked, and the arms were connected. First, the dilated renal pelvis was identified behind the thin mesocolon. The mesocolon was entered and renal pelvis was dissected completely from the surrounding fat. Then, the renal pelvis was opened after adequate dissection and stones were visualized inside the calyces. By Prograsp forceps, stones were removed from all the calyces under vision and were extracted from the assistant trocar. Finally, the pylotomy incision was closed using 4 0 Maxon in a continuous fashion and the mesocolon was closed using 3 0 PDS interrupted sutures. A JP drain was placed. Result Operative time was forty-five minutes, blood loss was 100 ml. The patient was discharged after 48 hours with no immediate complications. Conclusion The utilization of minimal invasive surgery using the robot to extract multiple pelvicalyceal stones from a horseshoe kidney without reflecting the mesocolon proved to be a feasible and novel way in the management of complex stone disease improving the outcome with minimal morbidity.

    Pancreatic pseudocysts are generally treated by endoscopic cystogastrostomy. However, difficult cases involving abscess, necrosis, or risk of hemorrhage often require surgical intervention. Here, we report a case of a robotically assisted cystogastrostomy. The patient presented with an infected pseudocyst with adjacent varices. Use of the da Vinci Surgical System allowed us to create a widely patent anastomosis between the pseudocyst and the stomach. The patient tolerated the procedure well without any complications. This report demonstrates the feasibility of robotic cystogastrostomy. PMID:27637530

    2016-07-01

    Minimally invasive laparoscopic surgery for rectal cancer has undergone a significant evolution during the last decades and has become the standard approach in specialized centers with better short-term and comparable oncological outcome to open surgery. The laparoscopic approach remains challenging and has various inherent technical challenges particularly associated with rectal cancer resection. Robotic colorectal surgery using the da Vinci® surgical system has been successfully introduced into clinical practice during recent years and provides specific technical advantages. Studies have shown that the robotic approach in colorectal surgery is safe and feasible with comparable results. It is associated with low conversion rates, more R0 situations for low rectal cancer with larger tumors and more neoadjuvant treatment compared to standard laparoscopy. Robot-assisted surgery is an attractive development of minimally invasive surgery and should also be further evaluated with mandatory monitoring of outcome parameters in registries in Germany.

    Minimally invasive laparoscopic surgery replaces many open surgery procedures in urology due to its advantages concerning post-operative morbidity. However, the technical challenges and need of learning have limited the application of this method to the work of highly qualified surgeons. The introduction of da Vinci surgical system has offered important technical advantages compared to the laparoscopic surgical procedure. Robot-assisted radical prostatectomy became a largely accepted procedure. It has paved the way for urologists to start other, more complex operations, decreasing this way the operative morbidity. The purpose of this article is to overview the history of robotic surgery, its current and future states in the treatment of the cancer. We present our robot-assisted radical prostatectomy and the results. PMID:25260081

  10. Quantum robots plus environments.

    Energy Technology Data Exchange (ETDEWEB)

    Benioff, P.

    1998-07-23

    A quantum robot is a mobile quantum system, including an on board quantum computer and needed ancillary systems, that interacts with an environment of quantum systems. Quantum robots carry out tasks whose goals include making specified changes in the state of the environment or carrying out measurements on the environment. The environments considered so far, oracles, data bases, and quantum registers, are seen to be special cases of environments considered here. It is also seen that a quantum robot should include a quantum computer and cannot be simply a multistate head. A model of quantum robots and their interactions is discussed in which each task, as a sequence of alternating computation and action phases,is described by a unitary single time step operator T {approx} T{sub a} + T{sub c} (discrete space and time are assumed). The overall system dynamics is described as a sum over paths of completed computation (T{sub c}) and action (T{sub a}) phases. A simple example of a task, measuring the distance between the quantum robot and a particle on a 1D lattice with quantum phase path dispersion present, is analyzed. A decision diagram for the task is presented and analyzed.

  11. Engineering robust intelligent robots

    2010-01-01

    The purpose of this paper is to discuss the challenge of engineering robust intelligent robots. Robust intelligent robots may be considered as ones that not only work in one environment but rather in all types of situations and conditions. Our past work has described sensors for intelligent robots that permit adaptation to changes in the environment. We have also described the combination of these sensors with a "creative controller" that permits adaptive critic, neural network learning, and a dynamic database that permits task selection and criteria adjustment. However, the emphasis of this paper is on engineering solutions which are designed for robust operations and worst case situations such as day night cameras or rain and snow solutions. This ideal model may be compared to various approaches that have been implemented on "production vehicles and equipment" using Ethernet, CAN Bus and JAUS architectures and to modern, embedded, mobile computing architectures. Many prototype intelligent robots have been developed and demonstrated in terms of scientific feasibility but few have reached the stage of a robust engineering solution. Continual innovation and improvement are still required. The significance of this comparison is that it provides some insights that may be useful in designing future robots for various manufacturing, medical, and defense applications where robust and reliable performance is essential.

    Robotics of the current day have advanced significantly from early computer-aided design/manufacturing systems to modern master-slave robotic systems that replicate the surgeon's exact movements onto robotic instruments in the patient. • Globally >300,000 robotic procedures were completed in 2010, including ≈98,000 robot-assisted radical prostatectomies. • Broadening applications of robotics for urological procedures are being investigated in both adult and paediatric urology. • The use of the current robotic system continues to be further refined. Increasing experience has optimized port placement reducing arm collisions to allow for more expedient surgery. Improved three-dimensional camera magnification provides improved intraoperative identification of structures. • Robotics has probably improved the learning curve of laparoscopic surgery while still maintaining its patient recovery advantages and outcomes. • The future of robotic surgery will take this current platform forward by improving haptic (touch) feedback, improving vision beyond even the magnified eye, improving robot accessibility with a reduction of entry ports and miniaturizing the slave robot. • Here, we focus on the possible advancements that may change the future landscape of robotic surgery.

    Science.gov (United States)

    Fugal, Mario

    2012-10-01

    In order to create precision magnets for an experiment at Oak Ridge National Laboratory, a new reverse engineering method has been proposed that uses the magnetic scalar potential to solve for the currents necessary to produce the desired field. To make the magnet it is proposed to use a copper coated G10 form, upon which a drill, mounted on a robotic arm, will carve wires. The accuracy required in the manufacturing of the wires exceeds nominal robot capabilities. However, due to the rigidity as well as the precision servo motor and harmonic gear drivers, there are robots capable of meeting this requirement with proper calibration. Improving the accuracy of an RX130 to be within 35 microns (the accuracy necessary of the wires) is the goal of this project. Using feedback from a displacement sensor, or camera and inverse kinematics it is possible to achieve this accuracy.

    Grasping an object is a matter of first moving a prehensile organ at some position in the world, and then managing the contact relationship between the prehensile organ and the object. Once the contact relationship has been established and made stable, the object is part of the body and it can move in the world. As any action, the action of grasping is ontologically anchored in the physical space while the correlative movement originates in the space of the body. Robots-as any living system-access the physical space only indirectly through sensors and motors. Sensors and motors constitute the space of the body where homeostasis takes place. Physical space and both sensor space and motor space constitute a triangulation, which is the locus of the action embodiment, i.e. the locus of operations allowing the fundamental inversion between world-centered and body-centered frames. Referring to these three fundamental spaces, geometry appears as the best abstraction to capture the nature of action-driven movements. Indeed, a particular geometry is captured by a particular group of transformations of the points of a space such that every point or every direction in space can be transformed by an element of the group to every other point or direction within the group. Quoting mathematician Poincaré, the issue is not find the truest geometry but the most practical one to account for the complexity of the world [1]. Geometry is then the language fostering the dialog between neurophysiology and engineering about natural and artificial movement science and technology. Evolution has found amazing solutions that allow organisms to rapidly and efficiently manage the relationship between their body and the world [2]. It is then natural that roboticists consider taking inspiration of these natural solutions, while contributing to better understand their origin.

  11. Robotics in Japan

    International Nuclear Information System (INIS)

    In September 1986, a group of German scientists visited Japanese institutions dealing with advanced robotics research, to gain a deeper insight in the Japanese status of this technology. Research projects found and discussions led in seven leading research institutes and seven firms are reported. Advanced robot or handling systems to ease or avoid human exposure to activities in harsh, demanding or dangerous conditions or environment are mainly dealt with. The Japanese show vast research activities in this area in the pre-competitive stage especially in the nuclear and underwater application area. (orig.)

    Microwave Vision (MV), a concept originally developed in 1985, could play a significant role in the solution to robotic vision problems. Originally our Microwave Vision concept was based on a pattern matching approach employing computer based stored replica correlation processing. Artificial Neural Network (ANN) processor technology offers an attractive alternative to the correlation processing approach, namely the ability to learn and to adapt to changing environments. This paper describes the Microwave Vision concept, some initial ANN-MV experiments, and the design of an ANN-MV system that has led to a second patent disclosure in the robotic vision field.

    Robust Real-Time Reconfigurable Robotics Software Architecture (R4SA) is the name of both a software architecture and software that embodies the architecture. The architecture was conceived in the spirit of current practice in designing modular, hard, realtime aerospace systems. The architecture facilitates the integration of new sensory, motor, and control software modules into the software of a given robotic system. R4SA was developed for initial application aboard exploratory mobile robots on Mars, but is adaptable to terrestrial robotic systems, real-time embedded computing systems in general, and robotic toys.

    One of the long-term goals in evolutionary robotics is to be able to automatically synthesize controllers for real autonomous robots based only on a task specification. While a number of studies have shown the applicability of evolutionary robotics techniques for the synthesis of behavioral control, researchers have consistently been faced with a number of issues preventing the widespread adoption of evolutionary robotics for engineering purposes. In this article, we review and discuss the open issues in evolutionary robotics. First, we analyze the benefits and challenges of simulation-based evolution and subsequent deployment of controllers versus evolution on real robotic hardware. Second, we discuss specific evolutionary computation issues that have plagued evolutionary robotics: (1) the bootstrap problem, (2) deception, and (3) the role of genomic encoding and genotype-phenotype mapping in the evolution of controllers for complex tasks. Finally, we address the absence of standard research practices in the field. We also discuss promising avenues of research. Our underlying motivation is the reduction of the current gap between evolutionary robotics and mainstream robotics, and the establishment of evolutionary robotics as a canonical approach for the engineering of autonomous robots.
