  1. Da Vinci robot emergency undocking protocol.

    O'Sullivan, O E; O'Sullivan, S; Hewitt, M; O'Reilly, B A


    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

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

    Iavazzo, Christos; Gkegkes, Ioannis D.


    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

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


    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.

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

    Abrishami, Payam; Boer, Albert; Horstman, Klasien


    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

  12. Side docking of the da Vinci robotic system for radical prostatectomy: advantages over traditional docking.

    Cestari, Andrea; Ferrari, Matteo; Zanoni, Matteo; Sangalli, Mattia; Ghezzi, Massimo; Fabbri, Fabio; Sozzi, Francesco; Rigatti, Patrizio


    The standard low lithotomic position, used during robot-assisted radical prostatectomy (RARP), with prolonged positioning in stirrups together with steep Trendelenburg may expose the patient to neurapraxia phenomena of the lower limbs and can rarely be used in patients with problems of hip abduction. To overcome these hurdles, we evaluated the clinical benefits of "side docking" (SD) of the da Vinci(®) robotic system in comparison to "traditional docking" (TD). A cohort of 120 patients submitted to RARP were prospectively randomized into two groups by docking approach: SD with the patient supine with lower limbs slightly abducted on the operating table, and TD docking time, intraoperative number of collisions between the robotic arms and postoperative neurological problems in the lower limbs were noted. Descriptive statistics was used to analyze outcomes. Docking time was shorter for the SD group [SD: median 13 min (range 10-18); TD: median 21 min (range 15-34)]. None in the SD group and six of 60 patients (10%) in the TD group suffered from temporary (<30 days) unilateral neurological deficits of the lower limbs. In both groups no collisions between the robotic arms occurred. The SD approach is technically feasible. It does not cause collisions between the robotic arms, and is a reliable method for reducing the setup time of RARP. The supine position of the patient may prevent neurological complications of the lower limbs. Based on these results, SD has become the standard docking technique used by our department.

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

    Fujiwara, Kazunori; Fukuhara, Takahiro; Niimi, Koji; Sato, Takahiro; Kitano, Hiroya


    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. PMID:26530845

    Lunar robotic functions include: 1. Transport of crew and payloads on the surface of the moon; 2. Offloading payloads from a lunar lander; 3. Handling the deployment of surface systems; with 4. Human commanding of these functions from inside a lunar vehicle, habitat, or extravehicular (space walk), with Earth-based supervision. The systems that will perform these functions may not look like robots from science fiction. In fact, robotic functions may be automated trucks, cranes and winches. Use of this equipment prior to the crew s arrival or in the potentially long periods without crews on the surface, will require that these systems be computer controlled machines. The public release of NASA's Exploration plans at the 2nd Space Exploration Conference (Houston, December 2006) included a lunar outpost with as many as four unique mobility chassis designs. The sequence of lander offloading tasks involved as many as ten payloads, each with a unique set of geometry, mass and interface requirements. This plan was refined during a second phase study concluded in August 2007. Among the many improvements to the exploration plan were a reduction in the number of unique mobility chassis designs and a reduction in unique payload specifications. As the lunar surface system payloads have matured, so have the mobility and offloading functional requirements. While the architecture work continues, the community can expect to see functional requirements in the areas of surface mobility, surface handling, and human-systems interaction as follows: Surface Mobility 1. Transport crew on the lunar surface, accelerating construction tasks, expanding the crew s sphere of influence for scientific exploration, and providing a rapid return to an ascent module in an emergency. The crew transport can be with an un-pressurized rover, a small pressurized rover, or a larger mobile habitat. 2. Transport Extra-Vehicular Activity (EVA) equipment and construction payloads. 3.

Die Anzahl der Institutionen, die einschlägige Programme lancierten und die chirurgischen Anwendungsbereiche, die sich der Robotertechnik bedienen, haben exponentiell zugenommen. Privatspitäler und akademische Zentren – Centers in den USA und in Europa – überall werden je eigene Wege und Verfahren beschritten. Materialien und Methoden: Die Daten, die von Intuitive Surgical, dem US-amerikanischen Urologenverband und vom Accreditation Council for Graduate Medical Education bereitgestellt und an jüngsten nationalen Konferenzen über Roboterchirurgie präsentiert wurden, wurden assimiliert und auf praktische Muster und Standards analysiert. Ergebnisse: Die rasche Verbreitung robotergestützter chirurgischer Eingriffe ist auf die vereinten Anstrengungen von Gesundheitseinrichtungen und Patientengruppen zur Förderung dieser Technik sowie auf die innovativen Werbemethoden von Intuitive(R Surgical zurückzuführen. Die bessere Visualisierung vitaler Strukturen, die einfachere und präzisere Gewebsmanipulation und die Verbesserung einiger kurzfristiger Parameter sind die Hauptpunkte der Unterstützungskampagne. Am Anfang der Initiative zum Start eines europäischen Roboterprogramms standen Versuche, die speziellen chirurgischen Verfahren zu modernisieren. In den Vereinigten Staaten spielen für die Entscheidung einer Institution, in das DaVinci Robot(R-System zu investieren, Marktkräfte eine bedeutende Rolle, die auf tatsächliche bzw. empfundene Unterschiede zwischen den Konsequenzen bei vorhandenem bzw. nichtvorhandenem Roboterprogramm zurückzuführen sind. In Asien ist die Kaufentscheidung vom Wunsch bestimmt, mit den Führenden "mitzuhalten". Schlußfolgerungen: Die Roboterchirurgie wird bleiben. Die aktuelle Technologie, wie wir sie kennen, ist im Hinblick auf die Anwendungspotenziale in der Zukunft erst die Spitze des Eisbergs.

  19. Robotic-assisted laparoscopic radical nephrectomy using the Da Vinci Si system: how to improve surgeon autonomy. Our step-by-step technique.

    Davila, Hugo H; Storey, Raul E; Rose, Marc C


    Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. 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.

    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.

  17. Integration of robotics and neuroscience beyond the hand: What kind of synergies?. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    d'Avella, Andrea


    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?

Geralmente, o mecanismo de resistência aos herbicidas inibidores da ALS é considerado como insensibilidade da enzima ao herbicida, ou seja, a alguma alteração no sítio de ligação herbicida-enzima. No entanto, mecanismos de tolerância de culturas aos herbicidas inibidores da ALS são observados, como as diferenças quanto a absorção, translocação e degradação, antes que o produto alcance o local de ação. O objetivo deste trabalho foi avaliar aspectos de nível e local preferencial de absorção e a translocação do herbicida pirazosulfuron-ethyl, na determinação do mecanismo de resistência de um ecótipo de Sagittaria montevidensis resistente aos herbicidas inibidores da ALS. Foram instalados experimentos em BOD e em casa de vegetação. Os tratamentos foram compostos de doses exponenciais do herbicida pirazosulfuron-ethyl (2(0x, 2²x, 2(4x, 2(6x e 2(8x em relação à dose usual - 20 g i.a. ha-1, aplicadas individualmente na parte aérea, raiz e sementes de ecótipos resistente e suscetível. Os resultados mostraram haver diferenças entre o ecótipo resistente e o suscetível quanto ao sítio preferencial de absorção do herbicida pirazosulfuron-ethyl.The ALS-inhibiting herbicides are highly effective when applied in low rates, presenting low toxicity to mammalians, wide control spectrum and, some of them, long soil persistence. Usually, the resistance mechanism for ALS inhibitors is due to the lack of enzyme sensitivity to the herbicide, resulting from alterations in the enzyme conformation. However, crop tolerance mechanisms are observed, such as

  2. Robotic assisted minimally invasive surgery

    Palep Jaydeep


    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.

  3. A heurística do medo, muito além da precaução

    Ricardo Abramovay


    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.

    Murphy, Declan G; Ben J. Challacombe; Lail-U-Mah Zaheer; M. Shamim Khan; Prokar Dasgupta


    Robotic technology for use in surgery has advanced considerably in the past 10 years. This has become particularly apparent in urology where robotic-assisted radical prostatectomy using the da VinciTM surgical system (Intuitive Surgical, CA) has become very popular. The use of robotic assistance for benign urological procedures is less well documented. This article considers the current robotic technology and reviews the situation with regard to robotic surgery for benign urological conditions.

    Full Text Available L'oralità risulta primaria rispetto alla scrittura sia per quanto riguarda la razza umana (filogenesi sia per quanto riguarda lo sviluppo individuale (ontogenesi, tuttavia essa ha sempre goduto di minor prestigio della scrittura. 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

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

    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

  5. A publicity e a publicidade (para além da propaganda

    Cassiano Ferreira Simões


    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.

    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.

  11. Robot Futures

    Christoffersen, Anja; Grindsted Nielsen, Sally; Jochum, Elizabeth Ann;

    Robots are increasingly used in health care settings, e.g., as homecare assistants and personal companions. One challenge for personal robots in the home is acceptance. We describe an innovative approach to influencing the acceptance of care robots using theatrical performance. Live performance is...... a useful testbed for developing and evaluating what makes robots expressive; it is also a useful platform for designing robot behaviors and dialogue that result in believable characters. Therefore theatre is a valuable testbed for studying human-robot interaction (HRI). We investigate how audiences...... perceive social robots interacting with humans in a future care scenario through a scripted performance. We discuss our methods and initial findings, and outline future work....

  13. Multiresolutional Filter Application for Spatial Information Fusion in Robot Navigation

    Ciftcioglu, &#;zer


    The detailed description of processing of spatial information for a perceptual robot is described. Especially, the perception is considered to be a probabilistic concept and defined as such (Ciftcioglu, ?., Bittermann, M.S. et al., 2006) so that the probabilistic consideration in perceptual robot is desirable for human-like robot navigation. This facilitates the robotic movement coupling the cognition of a robot with the environment. In this context, Bayesian

  14. Feasibility Study of Low Force Robotic Friction Stir Process and its Effect On Cavitation Erosion and Electrochemical Corrosion for Ni Al Bronze Alloys

    Ahmad, Azman; Li, Huijun; Pan, Zengxi; Cuiuri, Dominic; van Duin, Stephen; Larkin, Nathan; Polden, Joseph; Lane, Nathan


    Robotic friction stir processing (FSP) has not been widely researched to date. This is perhaps due to the limited force capabilities of industrial robots in comparison with dedicated commercial FSP equipment. When operating a FSP machine, the force used to plunge the tools may range from 5000 to 8000 N which is currently beyond the capability of most robots. However, the capacity of robotic manipulators is increasing, so low force friction stir processing is becoming feasible. The ability of the robot arm to apply a controlled force that is normal to a 3-dimensional surface without the need to reorient the workpiece makes it a very useful tool for FSP of complex components. In this analysis, a robot arm with a capacity of 2500 N is used to improve the surface properties of nickel aluminum bronze (NAB) using low force FSP. Multiple passes were applied to the surface of the test sample for a more consistent spread of the stir zone. The sample was then microhardness tested and demonstrated a 62 pct increase in surface hardness. Cavitation erosion testing of the original and processed surfaces was also performed as per ASTM G-32. The erosion rate of the processed NAB sample was 44 pct of the rate experienced by the original cast NAB sample. Finally, the corrosion potentials of FSP NAB were measured at 45 mV less anodic than the unprocessed material, indicating that the processed material is more noble relative to the cast NAB sample.

  15. Urologic robots and future directions

    Mozer, Pierre; Stoianovici, Dan; 10.1097/MOU.0b013e32831cc1ba


    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. The paradigm of image-guided robots is close to clinical availability and the most advanced robots are presented with end-use...

    Full Text Available OBJETIVO: Investigar a vivência das mães entre a suspeita, o diagnóstico de surdez e o encaminhamento para habilitação, bem como a percepção delas a respeito da forma como foi dado e explicado o diagnóstico. 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.

  7. Are we ready to move beyond the reductionist approach of classical synergy control?. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    Lacquaniti, Francesco; Ivanenko, Yuri P.; Zago, Myrka


    Starting from the classical concepts introduced by Sherrington [1] and considerably elaborated by Bernstein [2], much has been learned about motor synergies in the last several years. The contributions of the group funded by the European project "The Hand Embodied" are remarkable in the field of biological and robotic control of the hand based on synergies, and they are reflected in this enjoyable review [3]. There, Santello et al. adopt Bernstein's definition of motor synergies as multiple elements working together towards a common goal, with the result that multiple degrees of freedom are controlled within a lower-dimensional space than the available number of dimensions.

  15. 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.

    Ficuciello, Fanny; Siciliano, Bruno


    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. The integration of

  16. Robot vision

    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

  6. Robot visions.

    Castañeda, Claudia; Suchman, Lucy


    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.

  7. Robotic transportation.

    Lob, W S


    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.

  16. Robotic Telesurgery: Benefits Beyond Barriers

    Bijoy Johnson


    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.

    Using robots in industrial welding operations is common but far from being a streamlined technological process. The problems are with the robots, still in their early design stages and difficult to use and program by regular operators; the welding process, which is complex and not really well known and the human-machine interfaces, which are unnatural and not really working. In this article, these problems are discussed, and a system designed with the double objective of serving R&D efforts o...

  20. Para além da paz liberal? respostas ao "retrocesso" Beyond liberal peace? responses to "backsliding"

    Oliver P Richmond


    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. What often emerges is a hybrid form of the liberal peace, subject to powerful local critiques, sometimes resistance, and to the perception that international peacebuilding is failing to

  8. Characterization of Si3N4-Al interface after corrosion tests Caracterização da interface Si3N4-Al após testes de corrosão

    C. dos Santos


    Full Text Available Silicon nitride is a covalent ceramic material of high corrosion resistance and mechanical stability at elevated temperatures. Due to these properties, its use in metallurgical processes, such as the casting of alloys, is increasing. Therefore, the characterization of the interface between Si3N4 and the casted metal is of great importance to investigate possible interactions, which might deteriorate the ceramic mould or contaminate the metal. In this work, the use of Si3N4 as crucible material for Al-casting has been studied, by investigating the corrosion attack of liquid Al at a temperature of 1150 ºC during 30 days in air. The interface was characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. It has been found that due to superficial oxidation two oxide layers form - SiO2 on Si3N4 and Al2O3 on Al - which effectively hinder further reactions under the conditions studied, confering high corrosion resistance to the Si3N4 crucible.Nitreto de silício (Si3N4 é um material cerâmico covalente de elevada resistência à corrosão e estabilidade mecânica em temperaturas elevadas. Devido a essas propriedades, sua utilização em processos metalúrgicos, tais como em fundição de ligas metálicas, é crescente. Desta forma, a caracterização da interface entre Si3N4 e metais fundidos é de grande interesse para investigar possíveis interações as quais poderão deteriorar o material cerâmico e/ou contaminar o metal. Nesse trabalho o uso de Si3N4 como material base de cadinhos para fundição de alumínio foi estudado, pela investigação do ataque corrosivo de Al líquido a 1150 ºC durante 30 dias, ao ar. A interface foi caracterizada por difração de raios X, microscopia eletrônica de varredura e espectroscopia de energia dispersiva. É encontrado que devido à oxidação superficial dois óxidos se formam - SiO2 no Si3N4 e Al2O3 no Al - os quais evitam possíveis reações sob as condi

  9. Robot vision for nuclear advanced robot

    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)

    In the present work, the Ti-Nb-2%Al alloys, with the rate varied Nb from 15 to 40%, they were submitted to the quenched since 1000 deg C, in water, to verify the influence of Nb in the structure and phase composition. The alloys were obtained in a process of five coalitions in an oven to electric arch and, soon afterwards, wrought the hot and homogenized to 1200 deg C, for 10 hours. After the quenching and conventional metallographic preparation of the samples obliquely cut, the alloys were examined through the optic microscopic, diffraction of ray-X and Vickers hardness. The very defined correlation was shown between the niobium rate and the structure resulting from the quenched alloys. The phase martensitic was revealed in the alloy with 15% Nb, the phases martensitic and beta metastable in the alloys containing above 30% Nb and the phase beta in the alloys with 38% Nb and 40% Nb. the hardness of the phase martensitic increases with the increment of the niobium rate.

  13. Neuro-prosthetic interplay. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by M. Santello et al.

    Schieber, Marc H.


    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.

  18. A fundação do subjetivo: o hábito para além da psicologia The subjective foundation: habit beyond psychology

    Auterives Maciel Junior


    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.

  19. Toward the Automated Synthesis of Cooperative Mobile Robot Teams

    Parker, L.E.


    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




    Full Text Available The ability of intuition and self- learning in humans is responsible for developing their intelligence, reasoning and socialising. All this human characteristics can enable the robots to evolve into humans. In this context i explain that robots with developing intelligence can solve the problems of various scientific phenomenon such as black-hole, time travels and even in robotics the problems in sensors and actuators which do not impart human level DOF and movement thus making them do everything we can do. Imagine a robot doing yoga, karate, even a ballet all by itself without the rusty old controls and commands. Researchers have come with all kinds of robots and best of all social robots for social interaction so we have come with all kinds of robots what’s next? Robot scientists and researchers! Why not? It is highly evident that robot can think in new dimensions to solve issues.

  3. Towards Sociable Robots

    Ngo, Trung Dung

    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 and...

  11. Continuum robots and underactuated grasping

    N. Giri


    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.

    This paper was presented at the IFToMM/ASME International Workshop on Underactuated Grasping (UG2010, 19 August 2010, Montréal, Canada.

    Ruberval Azevedo


    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.

  16. Para além da ordem: o cotidiano prisional da Bahia oitocentista a partir da correspondência de presos Beyond order: daily prison life in Nineteenth-Century Bahia according to prisoners' correspondence

    Cláudia Moraes Trindade


    Full Text Available Este artigo tem o objetivo de discutir a comunidade prisional na Bahia Oitocentista, a partir das correspondências de presos. Faço uma análise dessa documentação buscando reconstruir parte do cotidiano dos presos, pressupondo a existência de uma ordem paralela, com igual ou maior força do que a oficial, mas que não anulava a arbitrariedade e a violência desta última. Entretanto, essa ordem paralela podia ser rompida, a qualquer momento, seja por confrontos diretos entre os próprios presos ou entre os presos e os funcionários da prisão. Dentre os tipos de protesto, a escrita foi um dos mais utilizados pelos presos e, dependendo da estratégia sugerida nas cartas, era possível conquistar espaços sem romper com a ordem prisional. O recurso à escrita foi utilizado por presos, letrados ou não, de diferentes condições jurídicas - escravos, libertos e livres -, independentemente do tipo de pena que estivessem cumprindo.The aim of this article is to discuss the prison community in Bahia during the 19th century, using the correspondence written by prisoners. I analyze this documentation in an attempt to reconstruct the daily life of the prisoners, presupposing the existence of a parallel order equal to or more powerful than the official prison order, but that did not end the arbitrariness and the violence of the latter. This parallel order could be broken any moment, whether because of direct confrontation among the prisoners themselves, or due to confrontation between prisoners and prison staff. Among different types of protest, writing was widely used by prisoners and, depending on the strategy suggested in the letters, it was possible to obtain gains without breaking the prison order. Written appeals were used by prisoners, educated or not, of different legal conditions, slaves, freed and free, independent of the type of sentence they were serving.

  1. Robots and manipulators

    Heer, E.


    Robots are defined and described for various applications. The key feature of robots is programmability, which allows teleoperation, repair work in hazardous situations, and unsupervised operation in industrial functions. Two types of robots now exist: special purpose, with equipment for a specific task; and general purpose, which include nonservo-controlled robots, servo-controlled robots, and sensory control robots. Sensory robots are the most sophisticated, and are equipped with both internal control sensors and external sensors such as TV cameras, pressure detectors, laser range finders, etc. Sensory feedback to a central computer enables the robots to make appropriate modifications to the control program to adapt to new situations. Pattern recognition and scans for size are features of the TV sensors, and programs to develop a universal effector (hand) are outlined. Finally, robot programming in terms of manual, walkthrough, and textual methods are described, and the potential uses of robots for space and undersea construction and repair are discussed.

  2. Viejas y nuevas fronteras: de la caída del Muro al siglo XXI. Ensayo de reflexión desde la no-violencia

    Mario López Martínez


    Full Text Available Este artículo pretende analizar cómo se han producido cambios importantes en el mundo tras la caída del Muro de Berlín. Se ha acentuado la idea de un solo mundo, un solo sistema económico mundial, una sola humanidad. Se han producido importantes transformaciones: pérdida de legitimidad y de soberanía de los estados-nación, expansión del proceso de globalización, se ha extendido la idea de crisis civilizatoria, se han incrementado nuevas guerras asociadas a geopolíticas neoimperialistas, etc. Tras una década, 1989-1999, de optimismo internacional se ha pasado al pesimismo que inaugura el siglo xxi. La violencia estructural y física han aumentado significativamente, sin embargo, también han aumentado las diversas formas de protesta, intervención y vigilancia de la sociedad civil, tanto desde la defensa de los derechos humanos, como diferentes formas de la resistencia civil. Goliat ha aumentado su tamaño y los problemas que crea en el Planeta, pero David sigue denunciando que esta vía sólo conducirá a más violencia, más sufrimiento y más muertes. David recuerda que es necesario asegurar las bases por las que se humanice a la humanidad.

    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.)

  6. Hexapod Robot

    Begody, Ericka


    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 Os herbicidas constituem-se na principal medida de controle de plantas daninhas na cultura de soja; no entanto, a pressão de seleção causada pelo uso contínuo de produtos com o mesmo mecanismo de ação pode provocar a seleção de biótipos resistentes, como ocorreu com Euphorbia heterophylla L., que se mostrou resistente aos herbicidas inibidores da enzima acetolactato sintase (ALS em áreas dos Estados do Paraná e Rio Grande do Sul. Para comprovar possíveis novos casos, bem como alternativas para prevenção e manejo, coletaram-se sementes de plantas de E. heterophylla L., na região de Assis (SP, que sobreviveram a tratamentos, em que esses herbicidas foram sistematicamente aplicados nos últimos anos. Desenvolveu-se o experimento em casa de vegetação, comparando-se o biótipo resistente ao suscetível, quando submetido aos diversos herbicidas aplicados em pós-emergência. Aplicaram-se quando as plantas encontravam-se no estádio de duas a quatro folhas verdadeiras, nas doses zero, uma, duas, quatro e oito vezes a recomendada. Aos 20 dias após a aplicação, avaliaram-se os parâmetros relativos ao controle e produção de fitomassa epígea visando ao estabelecimento de curvas de doses-resposta, à obtenção dos fatores de resistência com base nos valores da DL50 e GR50, e à verificação da ocorrência de resistência múltipla. O biótipo resistente apresentou diferentes níveis de resistência aos herbicidas chlorimuron-ethyl e imazethapyr, demonstrando resistência cruzada aos inibidores da ALS dos grupos das sulfoniluréias e imidazolinonas. No entanto, foi eficientemente controlado nos tratamentos com fomesafen (250 g.ha-1, lactofen (120 g.ha-1, flumiclorac-pentil (40 g.ha-1, glufosinato de amônio (150 g.ha-1 e glyphosate (360 g.ha-1.Herbicides are the main tool for weed control in soybean crop, but the selection pressure attributed to the repeated application of the same herbicides and the same mechanism of action can

  10. Robotic intelligence kernel

    Bruemmer, David J.


    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.

[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.

  13. Tolerancia al daño inducido bajo solicitaciones de contacto cíclicas en carburos cementados WC-Co//Tolerance induced damage under cyclic contact loading of WC-Co cemented carbides

    David Coureaux‐Mustelier


    Full Text Available El comportamiento mecánico de los carburos cementados WC-Co ha sido estudiado en detalle teniendo en cuenta los defectos preexistentes del material (daño intrínseco. Sin embargo, la información sobre los efectos del daño inducido en servicio (daño extrínseco en la integridad estructural de estos materiales esescasa. En este contexto, en este trabajo se evalúa la influencia del daño extrínseco en la resistencia mecánica residual de dos calidades con microestructuras diferentes. Para ello, se emplea la técnica de indentación esférica como medio para generar daño de forma controlada. Los resultados muestran que al incrementar el tamaño de grano del carburo y el contenido de cobalto, la respuesta mecánica de carburos cementados frente al contacto esférico es cada vez más cuasi-plástica, bajo la aplicación de cargas tanto monotónicas como cíclicas, y en consecuencia el material muestra una mayor tolerancia al daño.Palabras claves: carburos cementados, indentación esférica, resistencia mecánica residual, tolerancia al daño._______________________________________________________________________________AbstractThe mechanical behavior of WC-Co cemented carbides has been studied in detail taking into account the pre-existing material (intrinsic damage defects. However, information on the effects of service-induced damage (extrinsic damage on the structural integrity of these materials is limited. In this context, in thispaper the influence of extrinsic damage on the residual strength of two grades with different microstructures is evaluated. With this purpose, a spherical indentation technique is employed as a means for generating a controlled damage. The results show that by increasing the grain size of the carbide and the cobalt content, the mechanical properties of cemented carbides compared to spherical contact isincreasingly quasi-plastic, under the application of both monotonic and cyclic loads, and consequently the

  14. Robotics in microsurgery: use of a surgical robot to perform a free flap in a pig.

    Katz, Ryan D; Rosson, Gedge D; Taylor, Jesse A; Singh, Navin K


    We present the concept that a surgical robot may be used to successfully perform a free flap. To study different microsurgical techniques, a porcine free flap model was developed in our laboratory. Dissection of the free flap model and isolation of the vessels were completed under traditional loupe magnification. The da Vinci robot was then used to perform vessel adventitiectomy and microanastomoses. The model was observed for 4 h postoperatively, noting flap color, temperature, capillary refill, and Doppler signal. At the end of this period, the flap was noted to be viable; anastomoses were evaluated and found to be grossly and microscopically patent. Advantages conferred by the da Vinci robot include elimination of tremor, scalable movements, fully articulating instruments with six degrees of spatial freedom, and a dynamic three-dimensional visualization system. Drawbacks include the cost and the absence of true microsurgical instruments. PMID:16178007

  15. Brasagem da zircônia metalizada com titânio à liga Ti-6Al-4V Brazing of metalized zirconia with titanium to Ti-6Al-4V alloy

    J. S. Pimenta


    Full Text Available Zircônia tetragonal estabilizada com ítria foi mecanicamente metalizada com titânio e a condição de molhamento avaliada com as ligas convencionais Ag-28Cu e Au-18Ni. Estas dissolveram o revestimento de titânio para uma completa distribuição deste metal ativo na superfície cerâmica, gerando uma liga ativa in situ e possibilitando adequadas ligações químicas ao metal base na temperatura de união. Os melhores resultados de molhamento foram selecionados para brasagem indireta em forno de alto-vácuo nas juntas ZrO2/Ti-6Al-4V. Testes de detecção de vazamento de gás hélio foram realizados na interface de união das juntas; amostras removidas na seção transversal de juntas estanques foram examinadas por técnicas de análise microestrutural. Formou-se uma camada escura adjacente à cerâmica metalizada, responsável pelo molhamento ocasionado pela liga Ag-28Cu. Entretanto, o uso da liga Au-18Ni resultou em precipitação de intermetálicos e microtrincamento interfacial. Perfis de microdureza através da interface resultante até onde a zircônia mostrou típico escurecimento não indicaram alternância significativa entre medições consecutivas; os resultados dos ensaios de resistência mecânica à flexão-3p foram considerados satisfatórios.Yttria tetragonal zirconia polycrystal was mechanically metallized with titanium and the wetting behavior on the ceramic surface was analyzed using the conventional fillers Ag-28Cu and Au-18Ni. These alloys had dissolved the active metal coating, which acts to zirconia reduction on its surface and promoting suitable chemical bonding to the metallic member. Better wetting results were selected for indirect brazing in a high-vacuum furnace for ZrO2/Ti-6Al-4V simple butt joints. Helium gas leak detection was made at the joints interface; samples were removed from the tight joints cross-section and examined by microstructural analysis techniques and EDX analysis. There was formation of a dark

  16. Transoral robotic surgery: concept and indications

    Gutiérrez-Fonseca R


    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.

    Jost, Céline; Grandgeorge, Marine; Le Pévédic, Brigitte; Duhaut, Dominique


    The robots are coming in our daily lives: companion robots, service robots, sociable robots, assistant robots, and so on. It is difficult to imagine their real roles in the future because humans' expectations seem unclear, probably because robots are new and little known. It is thus important to put human beings in relation with robots to understand what they want. This paper describes an experimentation which explored the added value of a robot in a memory game with 67 persons comparing thre...

  1. Robotics Potential Fields

    Jordi Lucero


    Full Text Available This problem was to calculate the path a robot would take to navigate an obstacle field and get to its goal. Three obstacles were given as negative potential fields which the robot avoided, and a goal was given a positive potential field that attracted the robot. The robot decided each step based on its distance, angle, and influence from every object. After each step, the robot recalculated and determined its next step until it reached its goal. The robot's calculations and steps were simulated with Microsoft Excel.

  2. Robotics for Human Exploration

    Fong, Terrence; Deans, Mathew; Bualat, Maria


    Robots can do a variety of work to increase the productivity of human explorers. Robots can perform tasks that are tedious, highly repetitive or long-duration. Robots can perform precursor tasks, such as reconnaissance, which help prepare for future human activity. Robots can work in support of astronauts, assisting or performing tasks in parallel. Robots can also perform "follow-up" work, completing tasks designated or started by humans. In this paper, we summarize the development and testing of robots designed to improve future human exploration of space.

  3. Modeling robot contour processes

    Whitney, D. E.; Edsall, A. C.

    Robot contour processes include those with contact force like car body grinding or deburring of complex castings, as well as those with little or no contact force like inspection. This paper describes ways of characterizing, identifying, and estimating contours and robot trajectories. Contour and robot are modeled as stochastic processes in order to emphasize that both successive robot cycles and successive industrial workpieces are similar but not exactly the same. The stochastic models can be used to identify the state of a workpiece or process, or to design a filter to estimate workpiece, shape and robot position from robot-based measurements.

  4. El deber de mitigar el daño en la Convención de Viena de 1980 sobre compraventa internacional de mercaderías: Una breve aproximación al tema.

    Maximiliano Rodríguez Fernández


    Full Text Available El deber de mitigar el daño se presenta como una derivación o una consecuencia natural del principio de la Buena Fe. Principio éste reconocido en numerosas sentencias arbitrales bajo diferentes denominaciones entre las que se destaca, el principio general del deber de información, el principio de negociar de buena fe, o el principio de ejecutar los contratos de buena fe. También se hace relación al Principio general del acreedor de disminuir el daño sufrido, el cual tiene su origen en la llamada “Duty to Mitigate” del Common Law. En el presente documento nos referiremos al deber de mitigar el daño tal y como ha sido contemplado en la Convención de Viena de 1980. Lo anterior, no sólo por la importancia de este instrumento para el comercio internacional, sino también porque el mismo ya ha sido sujeto de incorporación a la legislación colombiana y como tal consideramos es un buen punto de partida para el estudio del deber de mitigar en el derecho de los contratos. Lo anterior, no sin antes repasar brevemente las disposiciones sobre los efectos del incumplimiento y la indemnización de daños y perjuicios en la Convención de Viena de 1980.

  5. Soft robotics: a bioinspired evolution in robotics.

    Kim, Sangbae; Laschi, Cecilia; Trimmer, Barry


    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

  8. The aggregation and neurotoxicity of TDP-43 and its ALS-associated 25 kDa fragment are differentially affected by molecular chaperones in Drosophila.

    Jenna M Gregory

    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.

  10. Robotic VR simulation to measure competency: a step in the right direction.

    Lallas, Costas D


    There is widespread consensus on the vast potential of virtual reality (VR) simulation for robotic surgery; however, there is some debate on its current role in education and clinical practice. One of the conclusions that is consistently drawn across available validation studies is that VR simulation for robotic surgery in its current form appears to most benefit novice surgeons who do not have significant robotic surgery experience and who, amongst other things, require instruction on basic actions of the robot, such as camera movement, clutching, and arm coordination. Clinical translations of these skills include: training junior residents who are first being introduced to robotic cases; and educating an experienced surgeon who does not have formal robotic surgical training and is either seeking credentialing or maintenance of certification. However, once a surgeon has gained some outside experience with a robotic surgical system, whether in the dry lab, wet lab, or operating room settings (i.e. an intermediate or experienced robotic surgeon), there are currently less VR simulation applications. Noureldin, et al introduces another viable application of VR simulation using the da Vinci Surgical Skills Simulator (dVSSS), namely incorporating VR simulation into the Canadian Objective Structured Clinical Examinations (OSCE) to assess the basic robotic skills of urology Post-Graduate Trainees (PGTs). The authors are astute to transfer the current capabilities of the dVSSS for this utilization. During the OSCE, the station for this segment was only 20 minutes in length, allowing for only two of the less complex dVSSS skills tests. The authors also utilized the MScore performance metrics inherent to the system to evaluate for competency. Their definition of competency was based on the norm-referenced method, in which experts performed the tasks prior to the trainees, and a passing score was defined as the average of the experts' total scores minus one standard deviation

  11. Robots Social Embodiment in Autonomous Mobile Robotics

    Brian Duffy


    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.

  13. Robotic Surveying

    Suzy Cantor-McKinney; Michael Kruzic


    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

    Full Text Available OBJETIVO: O trabalho aqui descrito trata da avaliação de uma dieta experimental contendo Champingnon do Brasil (Agaricus brasiliensis como fonte de proteína em um modelo experimental de ratos. MÉTODOS: Para este propósito, foram selecionados 24 ratos Wistar machos, recém desmamados (21 dias divididos em 3 grupos de 8 animais cada, que foram alimentados com uma dieta padrão de caseína, ou com uma dieta experimental de proteína de Agaricus brasiliensis ambas contendo 10% de proteína e isoenergéticas ou ainda, com uma dieta com muito baixo teor de proteína. O ensaio biológico foi realizado em 28 dias, ao longo dos quais se determinou a concentração de nitrogênio na urina e nas fezes, além dos cálculos do Quociente de Eficiência Alimentar (ganho de peso dividido pelo consumo de dieta, do Quociente de Eficiência Protéica (ganho de peso dividido pelo consumo de proteína, da Razão Protéica Líquida (ganho de peso corrigido dividido pelo consumo de proteína e da Digestibilidade Verdadeira. RESULTADOS: Os resultados demonstraram que quando o Champignon do Brasil foi utilizado como fonte exclusiva de proteína na dieta, os índices de qualidade protéica apresentaram-se baixos (Quociente de Eficiência Alimentar=0,08, Quociente de Eficiência Protéica=0,92 e Razão Protéica Líquida=3,00, quando comparados com a dieta padrão caseína (Quociente de Eficiência Alimentar=0,30, Quociente de Eficiência Protéica=3,05 e Razão Protéica Líquida=4,21. Os índices obtidos para o grupo Agaricus mostraram-se comparáveis àqueles apresentados por alguns tipos de proteína vegetal e podem ser explicados por sua limitação em aminoácidos essenciais, notadamente a lisina e a leucina, respectivamente primeiro e segundo aminoácido limitante. CONCLUSÃO: Os dados apontam para a utilização da proteína do Agaricus brasiliensis como uma boa fonte para complementação protéica, quando combinada com outras culturas vegetais comuns na

  18. El principio de la responsabilidad civil objetiva limitada: un elemento de equilibrio sistémico que no contradice al denominado principio de la reparación integral del daño

    Gian Franco Rosso Elorriaga


    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.

  20. The Essential Elements of a Robotic-Assisted Laparoscopic Hysterectomy.

    Simpson, Khara M; Advincula, Arnold P


    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

  1. Estudo da viabilidade de obtenção de cerâmicas de SiC por infiltração espontânea de misturas eutéticas de Y2O3-AlN, Y2O3-Al2O3, R2O3-AlN Study of the viability to produce SiC ceramics by Y2O3-AlN, Y2O3-Al2O3, R2O3-AlN spontaneous infiltration

    G. C. R. Garcia


    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

  12. Emerging role of robotics in urology

    Kumar Rajeev


    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.

  13. Para além da autoconsciência moderna: a historiografia de Hans Ulrich Gumbrecht Beyond modern self-consciousness: the historiography of Hans Ulrich Gumbrecht

    Valdei Lopes de Araujo


    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.

  14. Transoral robotic surgery of the central skull base: preclinical investigations.

    Fernandez-Nogueras, F J J; Katati, M J; Arraez Sanchez, M A; Molina Martinez, M; Sanchez Carrion, M


    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 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

Para isso será preciso realizar reformas estruturais para ampliar o financiamento, fortalecer o pacto federativo, desmercantilizar a oferta de serviços e promover a eficiência da gestão pública. Também requer o resgate da democracia e da política, o reforço do papel do Estado e a gestão macroeconômica voltada para o objetivo de redistribuir renda e garantir direitos sociais.

  8. [Robotics and laparoscopic surgery].

    Martínez Ramos, Carlos


    Laparoscopic surgery has completely revolutionized modern surgery. In addition to its advantages, however, this approach also presents significant limitations. The most important are loss of the sense of depth, tactile sensation and resistance, as well as loss of natural hand-eye coordination and manual dexterity. The main motivation for the development of surgical robots is the possibility of eliminating all these limitations. Robots have acquired great potential to improve the operative possibilities of surgeons. Given the continual increase in the use of surgical robots, in the near future the structure and appearance of current operating rooms will change. The present article analyzes the origin and development of robotic systems, as well as the characteristics of the latest generation of robots. Because of the strong interest in robotic surgery and its future prospects, surgeons should be familiar with these emerging and innovative techniques. PMID:17040667

  9. Robot-laser system

    A robot-laser system is described for providing a laser beam at a desired location, the system comprising: a laser beam source; a robot including a plurality of movable parts including a hollow robot arm having a central axis along which the laser source directs the laser beam; at least one mirror for reflecting the laser beam from the source to the desired location, the mirror being mounted within the robot arm to move therewith and relative thereto to about a transverse axis that extends angularly to the central axis of the robot arm; and an automatic programmable control system for automatically moving the mirror about the transverse axis relative to and in synchronization with movement of the robot arm to thereby direct the laser beam to the desired location as the arm is moved

  10. Survival of falling robots

    Cameron, Jonathan M.; Arkin, Ronald C.


    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.
