    Las Técnicas de Reproducción Asistida (TRA) son paradigmáticas de una experimentación humana que no cumple con los requisitos científicos ni éticos, y que ha creado un grave problema intergeneracional. Se aceptaron, a pesar de ser muy invasivas y costosas, como un atajo en la lucha por la esterilidad debida a causas físicas, como es la obstrucción de las trompas de Falopio, con una investigación exclusivamente retrospectiva, y con estudios previos en animales muy insuficientes.

    2014-01-01

    Full Text Available Salud, contemporáneamente, se entiende como un estado de completo bienestar físico, mental y social, y no solamente la ausencia de enfermedad. La actividad asistida por animales cumple este concepto y ya se utiliza hace unos años, como medida complementaria al tratamiento farmacológico, con el objetivo de la mejora y el bienestar del paciente. Su eficacia se ha demostrado a través de estudios de todo el mundo, en diferentes áreas como pediatría, geriatría y psiquiatría, entre otros, y trayendo beneficios tanto físicos como para la salud mental de las personas institucionalizadas. Ante esta realidad, hemos tratado de identificar cuáles son las investigaciones publicadas sobre el tema hasta el año 2013, en cinco bases de datos principales (Bireme, Cochrane, Embase, Pubmed y Scielo de la palabra “animal-assisted activity”. Se excluyeron los elementos repetidos en la misma base de datos, así como uno en japonés , uno en alemán, y que se centró en la terapia asistida con animales y no en la actividad asistida por animales. 55 artículos fueron encontrados en las cinco bases de datos: Bireme (2 8, Embase (13 Cochrane (1 Pubmed (11 y Scielo (2. Sólo 17 artículos cumplieron los criterios de inclusión preestablecidos. Todos mostraron resultados positivos en la aplicación de la actividad asistida por animales para los enfermos o personas en el aislamiento social. De este modo, se puede observar que esta práctica, aunque importante para ayudar a la búsqueda de lo bienestar integral del paciente y que está siendo acepta y formalizado en muchos países, sigue estando muy poco extendida científicamente.

    Full Text Available We developed a new process for the synthesis of SiC whiskers assisted by microwaves; this is based on the mixture of silica xerogels and graphite powder. As energy source were used microwaves of 2.45 GHz and 1.0 kW of power RMS. On the other hand, mesoporous silica was synthesized via sol-gel, the precursors used were TEOS/H2O and ethanol. Throughanalysis of the BET is determined the value of averageporesize (3.0 nm and the surface area (1090 m2/g.By mean of X-Ray diffraction it was demonstrated that the silica obtained is an amorphous solid and, the powders obtained in the microwave synthesis are β-SiC. Synthesized SiC powders were observed using a SEM in secondary electron mode, it was observed that this powders consists of SiC whiskers. The effect of microwaves on the synthesis of whiskers of SiC is discussed in the present work.Se desarrolló un nuevo proceso para la síntesis de whiskers de SiC asistida por microondas, basada en la mezcla de xerogeles de sílice y grafito en polvo. Como fuente de energía se emplearon microondas de 2.45 GHz y 1.5 kW de potencia. La sílice mesoporosa se sintetizó vía sol-gel, los precursores usados para esta síntesis fueron TEOS/H2O y etanol. A través del análisis BET se determinó el valor de tamaño de poro promedio (3.0 nm y el área superficial (1090 m2/g. Mediante difracción de rayos-x método de polvos se demostró que la sílice sintetizada es amorfa y que los polvos obtenidos en el microondas corresponden a β-SiC. Para determinar la morfología de los whiskers de SiC se analizó por MEB en el modo de electrones secundarios. El efecto de las microondas en la síntesis de whiskers de SiC se discute en el presente trabajo.

    Full Text Available La fase final de toda cirugía es la sutura y su cicatriz correspondiente y, frecuentemente, ésta es la única secuela visible de una intervención. La técnica LASH (cicatrización cutánea asistida por láser, estimula los mecanismos de reparación de la piel por efecto térmico, condicionando la calidad de la cicatrización. Estudios experimentales en ratones comparando los resultados obtenidos en heridas quirúrgicas radiadas con laser diodo 810 nm tras ser suturadas, con los obtenidos en igual tipo de heridas suturadas de manera convencional, han demostrado que se consiguen cicatrices mucho menos visibles cuando se practica el tratamiento con láser. La histología confirma, comparativamente, una notable aceleración del proceso cicatricial con modificación del TGFβ (Transforming Growth Factor-Beta directamente implicado en la reparación tisular, en los animales en los que la sutura fue asistida por láser. Igualmente, el análisis tensiométrico demostró mayor resistencia a la acción de estiramiento mecánico en estas heridas. Estudios clínicos en pacientes sometidos a dermolipectomia, reducción mamaria y estiramiento facial, demuestran que al tratar con LASH una parte o una de las líneas de sutura, los análisis realizados tanto por los pacientes como por cirujanos independientes a los 8 días, 3 meses y un año, evidencian resultados más favorables para la técnica láser, Las dosis eficaces determinadas para las fluencias láser están entre 80 y 120 J/cm². La técnica LASH es simple de efectuar, reproducible, rápida y ofrece una clara evidencia de que es posible reducir considerablemente la cicatriz, logrando que ésta sea de mejor calidad y más estética.

    2011-04-01

    Full Text Available Resumen: En este trabajo, se presenta un método de filtrado adaptativo para la eliminación de las componentes involuntarias de las fuerzas de interacción entre el usuario y el andador por el apoyo de sus miembros superiores. Este proceso se basa en la atenuación selectiva de componentes relacionadas con las oscilaciones del tronco del sujeto durante la marcha. Para ello, se hace la estimación de la cadencia de marcha en tiempo real procesando las señales de distancia obtenidas por un subsistema ultrasónico mediante el algoritmo Weighted-Frequency Fourier Linear Combiner (WFLC. Este subsistema suministra la distancia entre los pies del usuario y el andador en tiempo real. La cadencia a su vez es usada para el ajuste de un filtro notch adaptativo construido a partir del algoritmo Fourier Linear Combiner (FLC que realiza el filtrado en tiempo real de las señales obtenidas del subsistema de medición de fuerzas de apoyo de antebrazos. El método propuesto ofrece una cancelación robusta y en tiempo real de cerca del 80% de la amplitud de las componentes indeseadas de frecuencia. La salida del algoritmo de filtrado propuesto permite así evidenciar componentes de fuerzas de bajo nivel pero muy importantes ya que están generadas por acciones intencionales y naturales asociadas a las intenciones de guiado del andador. Estas componentes serán utilizadas en el control de los motores del andador basándose en una arquitectura de control clásico que será desarrollada posteriormente.

    2012-01-01

    Full Text Available Se esterificaron ligninas de diferentes masas molares empleando radiación microondas y se evaluó la actividad superficial de los derivados obtenidos. La lignina se fraccionó por ultrafiltración utilizando membranas cerámicas de 15 y 8 KDa. Se emplearon anhídrido succínico y anhídrido glutárico para modificar la lignina. La actividad superficial de los derivados se evaluó midiendo la tensión superficial. Los espectros FTIR mostraron la incorporación de los grupos éster-ácido carboxílico en la lignina. Los productos esterificados disminuyeron la tensión superficial entre un 10-20% con respecto a la lignina original, siendo este efecto mayor para los productos esterificados con anhídrido glutárico a altas concentraciones. La incorporación de los nuevos grupos éster-ácido en la estructura lígnica le proporciona un mayor carácter anfifílico, debido a la presencia de nuevos grupos funcionales polares que permiten la adsorción en la superficie minimizando las fuerzas de atracción en el seno del líquido.

    la cápsula hasta el duodeno mediante endoscopia resulta muy útil. Describimos las indicaciones y los resultados de unos casos en que las técnicas endoscópicas tradicionales permitieron llevar la cápsula hasta el duodeno. Pacientes y métodos: se trata de una serie descriptiva y retrospectiva de casos. Se identificaron todos los pacientes en las situaciones citadas y se anotaron las indicaciones de la cápsula endoscópica, la técnica endoscópica de colocación, las complicaciones y el grado de cobertura del intestino delgado por las imágenes. Resultados: la colocación endoscópica de la cápsula se hizo necesaria en 13 pacientes (2,1% de todas las endoscopias con cápsula; 7 varones; media de edad - 47,9 ± 24,9 años, intervalo de 13 a 79 años. Las indicaciones de la colocación endoscópica fueron: incapacidad para tragar la cápsula (7, retención gástrica en exploraciones previas (3 y anomalías de la anatomía digestiva alta (3. En ocho casos, la cápsula se introdujo en la vía GI mediante: sólo la red para recuperar cuerpos extraños (3, la red y un capuchón transparente (2, el prototipo de un dispositivo a tal efecto (2 o una asa de polipectomía (1. Cinco pacientes ingirieron la cápsula, llevada después al duodeno con una asa de polipectomía (3 o una red para cuerpos extraños (2. No se produjeron complicaciones de importancia. La enteroscopia total fue posible en 10 pacientes (77%. Conclusiones: la colocación endoscópica de la cápsula en el duodeno sólo es necesaria rara vez, puede realizarse de forma segura con distintas técnicas y soluciona algunas de las principales limitaciones de la cápsula endoscópica. Las mejores metodologías son la utilización de una red y un capuchón transparente cuando el paciente no pudo ingerir la cápsula y sólo una red para capturarla en el estómago si la traga fácilmente.

    Larrea, A.

    2004-10-01

    Full Text Available A procedure for surface densification and/or texturing of Al2O3-YSZ (yttria stabilised zirconia ceramics with eutectic composition by means of laser surface melting is presented. By scanning a high-power laser beam on a ceramic surface, we achieve a textured and fully dense surface layer from 30 to 1000 microns thick. For example, using a thin diode laser line with fluence 1.23 kW/cm2 and 0.14 mm/s scan rate, the solidified layer has 560 μm depth. We get a low roughness and dense surface. The microstructure is fine (micron size due to the eutectic composition. The orientation of the microstructure is determined by the shape of the solid-liquid interface in the solidification process. We study the shape of this interface in transverse and longitudinal cross-sections in single as well as overlapping scans, which are required to process large surfaces. From the macroscopic point of view, the transition between adjacent scans is smooth. However, the microstructure presents discontinuity in the interphase spacing due to microstructural evolution in the heat affected region as well as the nucleation of an Al2O3 layer at the beginning of the crystal growth. The thermal shock inherent to the procedure generates cracks longitudinal and transverse to the scanning direction, as well as delaminating cracks. We analyse different possibilities to reduce this thermal shock. The best results are obtained by preheating the substrate, allowing us to process surfaces of Al2O3-YSZ eutectic ceramics 99% dense.Se presenta un procedimiento para la densificación y/o texturado superficial de cerámicas de Al2O3-YSZ (circona estabilizada con itria con composición eutéctica mediante fusión zonal asistida por láser.

    Full Text Available En este trabajo, la autora pretende determinar la posibilidad de conocer los orígenes de seres humanos nacidos bajo técnicas de reproducción humana asistida. Para ello, procedió a analizar el régimen proyectado en el territorio nacional, conjuntamente, a un análisis de las regulaciones extranjeras. Comprendidos en su trabajo se encuentran las visiones acerca de los derechos de toda persona a formar una familia; los derechos de los niños, niñas y adolescentes; y el derecho de los terceros involucrados en estas técnicas. Asimismo, realizo una reseña sobre cuestiones históricas y sociológicas, entre otras, que hacen al contexto de estas técnicas; permitiéndole arribar a la conclusión de que el derecho a conocer los orígenes necesita de un abordaje interdisciplinario, que debe darse no sólo desde el Estado; sino especialmente dentro del marco del seno familiar, con los debidos cuidados y afecto que sólo la familia puede brindar; todo esto acompañado de una necesaria y fundamental construcción social para insertar estos cambios en la cultura del país.

    Full Text Available El objetivo de nuestro estudio es valorar mediante ecografía y análisis estadístico la respuesta a la liposucción asistida por láser en abdomen y flancos. Para ello, se tuvo en cuenta la disminución del tejido adiposo, la retracción cutánea y el grado de satisfacción de las pacientes con los resultados. Realizamos un estudio retrospectivo sobre 340 cirugías en pacientes multíparas mayores de 40 años, con o sin diástasis de rectos, que rechazaron la abdominoplastia con lipectomía. Las intervenciones se efectuaron mediante liposucción a respectivamente en 924 y 9/5 11111, bajo sedo-analgesia y con anestesia tumescente. Los láseres se programaron para emisión en modo continuo, actuando al unísono con potencia de 20 W hasta alcanzar un promedio de entre 10 a 12 kJ de energía acumulada para los flancos, y de entre 12 a 18 kJ para el abdomen. La valoración subjetiva y objetiva se realizó mediante escala GAIS (Global Aesthetic Improvement Scale. Se tomaron fotografías antes, 1 y 6 meses después de la intervención. En abdomen se realizaron ecografías antes y 6 meses después de la cirugía, y se empleó t de Student como test de contraste para el estudio analítico. En 60 pacientes seleccionados aleatoriamente como muestra representativa se realizaron fotografías digitales de la superficie de la piel a fin de valorar comparativamente por programa de ordenador la textura-flacidez de la condición del tejido antes, 1 y 6 meses después de la cirugía. En ninguno de los resultados se observó isquemia y/o quemaduras. La disminución del tejido adiposo, según las ecografías, fue estadísticamente significativa (p<0,05 comparativamente a los 6 meses del tratamiento. La valoración de las fotografías antes y 6 meses después de la cirugía por un médico ajeno al estudio, al igual que la textura-flacidez cutánea, fue Buena o Muy Buena.

    chosen confiuration ARC/INFO-IDRISIVISUAL MODFLOW has shown its usefulness and versatility to face the modelization of this area, which is characterized for its complexity and big extension.En el presente trabajo se exponen los resultados obtenidos de la aplicación de un Código Numérico de Modelización Hidrogeológica (CNMH asistido por un Sistema de Información Geográfica (SIG a un área de 20.952 km2 de la cuenca media del Tajo que incluye tanto a las depresiones terciarias del Campo Arañuelo y de Madrid, parcialmente, como al sustrato Igneo-metamórfico del macizo Ibérico hasta una profundidad de 5.500 m. Geográficamente incluye las ciudades de Madrid, Toledo y Talavera de la Reina; el accidente tectónico del Jerte y la confluencia entre el río Tajo y el Tiétar constituyen el área más occidental. Los objetivos del trabajo son, estudiar la problemática de integrar en un modelo hidrogeológico regional de gran escala formaciones de características hidrogeológicas muy distintas, analizar y definir una configuración SIG-CNMH para aplicar en el estudio, y avanzar en el conocimiento regional desde una perspectiva integradora y multidisciplinar. Se trabaja con un modelo isótropo y cinco anisótropos, estos últimos considerando la influencia en el flujo de tres familias de accidentes tectónicos -N 105, N 142.5 y N 168.75- y una esquistosidad media regional N 140. La calibración se basa en piezometría restituida y aportaciones base de la red hidrográfica. Se obtuvieron distintos valores de los parámetros calibrados según el modelo. En todos los casos la calidad del ajuste global es correcta y aceptable; sin embargo, cada uno de los modelos ofrece mejor calidad de ajuste respecto a los restantes en los sectores donde los rasgos que representan coinciden con los del sistema real. La evolución de la permeabilidad en profundidad resultante de la calibración es coherente con la esperada, siendo las relaciones kx/kz = ky/kz = 1, en los primeros 200 m y 0

    endoscópicamente 24 tumores en 21 pacientes (edad media de 51,7 años; 71,5% varones. Las lesiones eran en su mayoría hallazgos incidentales en exploraciones indicadas por otros motivos. La resección se indicó en la mayoría de los casos por sospecha ecoendoscópica de tumor carcinoide. La ecoendoscopia además permitió establecer con claridad la capa de origen de la lesión y el tamaño de la misma. La extirpación se llevó a cabo en 13 casos (54,2% mediante la técnica convencional de polipectomía con asa, en 9 casos (37,5% asistida con inyección submucosa de suero salino y/o adrenalina y en 2 casos (8,3% tras ligar la lesión con bandas elásticas. En todos los casos la resección fue completa, sin recidivas durante el seguimiento. En un único caso se produjo una complicación mayor: una hemorragia postpolipectomía que se controló endoscópicamente. Conclusiones: la resección endoscópica de los tumores carcinoides, en pacientes bien seleccionados, es una técnica segura y eficaz permitiendo una resección completa en todos los casos con escasas complicaciones. La ecoendoscopia es la técnica de elección para seleccionar los pacientes candidatos a resección endoscópica.

    Full Text Available La principal fuente de información acerca de técnicas de reproducción asistida (TRA en Latinoamérica es el Registro Latinoamericano de Reproducción Asistida (RLA. El RLA se estableció en 1990, y corresponde al primer registro multinacional del mundo. A pesar de su carácter voluntario, reporta más del 90% de las técnicas de reproducción asistida realizadas anualmente. En los últimos años se han consolidado en la región en general -y en Chile en particularlas tendencias de: mejoría de los resultados; aumento de la edad de las pacientes; fertilización de ovocitos por ICSI; y disminución de la media de embriones transferidos y, consecuentemente, de la frecuencia de partos múltiples. En Chile, siete centros reportan sus casos anualmente al RLA. La mayoría de los ciclos realizados en nuestro país son financiados por las propias parejas, con escasa cobertura por los seguros de salud. Esto se ha traducido en un aumento insuficiente en el acceso a TRA.

Relevant databases were searched between March 10 and April 11, 2011, using the words: animal assisted therapy or treatment and chronic conditions or diseases. Thirty-one articles were found and 18 followed the inclusion and exclusion criteria. Research suggests that AAT/A is effective for different patient profiles, particularly children. Interaction with dogs has been found to increase positive behaviors, such as sensitivity and focus, in children with social disabilities. Decreased levels of pain have also been reported among child patients as a result of AAT/A. More research should be done in the area of children living with chronic diseases that require strict adherence to treatment, such as HIV, and on AAT/A's prospective use as an educational tool to teach children about the importance of self-care for their medical conditions.El objetivo de esta revisión fue describir la literatura existente sobre el uso de terapia y actividades asistidas por animales (AAT/A, como terapia coadyuvante en personas viviendo con enfermedades crónicas, y discutir la posible aplicación de esa práctica en niños que viven con SIDA.

    2014-06-01

    Full Text Available Metallurgical cokes are composed of graphitic carbon (s2p2 and different inorganic compounds with very different capacities to absorb microwave radiation. Moreover, due to the electric conductivity shown by the metallurgical cokes, microwave radiation produces electric arcs or microplasmas, which gives rise to hot spots. Therefore, when these cokes are irradiated with microwaves some parts of the particle experiment a rapid heating, while some others do not heat at all. As a result of the different expansion and stress caused by thermal the shock, small cracks and micro-fissures are produced in the particle. The weakening of the coke particles, and therefore an improvement of its grindability, is produced. This paper studies the microwave-assisted grinding of metallurgical coke and evaluates the grinding improvement and energy saving.Los coques metalúrgicos están compuestos mayoritariamente de carbono grafítico (s2p2 y diferentes compuestos inorgánicos con distintas capacidades de absorber la radiación de microondas. Cuando se irradian con microondas fragmentos de estos coques, algunas partes de las partículas experimentan un rápido calentamiento, mientras otras no. Además, debido a que el coque presenta una cierta conductividad eléctrica, al ser irradiados con microondas se producen de forma puntual arcos eléctricos o microplasmas, dando lugar a puntos muy calientes. Como consecuencia de las diferentes dilataciones y tensiones producidas por el choque térmico, se producen en las partículas pequeñas grietas y microfisuras. Esto produce una mayor fragilidad en las partículas de coque y un incremento en la molturabilidad de las mismas. En el presente artículo se estudia la molienda de coque asistida con microondas y se evalúan las mejoras en la molturabilidad y el ahorro de energía producido.

    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.

    Earth's upper atmosphere is an extreme environment: dry, cold, and irradiated. It is unknown whether our aerobiosphere is limited to the transport of life, or there exist organisms that grow and reproduce while airborne (aerophiles); the microenvironments of suspended particles may harbor life at otherwise uninhabited altitudes[2]. The existence of aerophiles would significantly expand the range of planets considered candidates for life by, for example, including the cooler clouds of a hot Venus-like planet. The X project is an effort to engineer a robotic exploration and biosampling payload for a comprehensive survey of Earth's aerobiology. While many one-shot samples have been retrieved from above 15 km, their results are primarily qualitative; variations in method confound comparisons, leaving such major gaps in our knowledge of aerobiology as quantification of populations at different strata and relative species counts[1]. These challenges and X's preliminary solutions are explicated below. X's primary balloon payload is undergoing a series of calibrations before beginning flights in Spring 2012. A suborbital launch is currently planned for Summer 2012. A series of ground samples taken in Winter 2011 is being used to establish baseline counts and identify likely background contaminants.

    Full Text Available Resumen: Se presenta un método de optimización multi-objetivo, aplicado al funcionamiento de las cadenas cinemáticas abiertas, analizando el caso del movimiento de una extremidad de un robot caminante electro-hidráulico. Para demostrar la efectividad del método propuesto, se aplica en dos casos de estudio. El primer caso muestra el movimiento de la extremidad sin obstáculos en su espacio de trabajo, y en el segundo se incluye la evasión de un obstáculo. Se usan como criterios de optimización, la minimización del desplazamiento angular de los eslabones con mayor consumo de energía y la minimización del valor absoluto máximo de la aceleración angular de los eslabones. En ambos casos se determinó una trayectoria que disminuye el consumo de energía en más de un 25% respecto de otros métodos planteados en la literatura, a la vez que se mejora el comportamiento dinámico del sistema evitando variaciones en la velocidad y la aceleración durante la fase de trasferencia, además de aumentar la precisión y exactitud de la posición del pie. Abstract: It presents a method of multi-objective optimization, applied to energy consumption of open kinematic chains, analyzing the case of the movement of an extremity of a walking electro- hydraulic robot. To demonstrate the effectiveness of the proposed method, it is applied in two cases of displacement. The first case shows the movement of the extremity without obstacles in its workspace and the second includes the evasion of an obstacle. The minimization of angular displacement of the links with higher energy consumption and the minimization of the maximum absolute value of the angular acceleration of the links are used as optimization criteria. In both cases a trajectory that reduces energy consumption by more than 25% over the other methods proposed in the literature, at the same time the dynamic behavior of the system by avoiding variations in the speed and the acceleration is improved

    Full Text Available El presente trabajo está dedicado a la optimización bajo criterios múltiples de la planificación de procesos de ensamble mecánico a partir de su modelo geométrico tridimensional. Se soporta sobre un enfoque que integra tanto información geométrica como restricciones tecnológicas del proceso de ensamble. En el desarrollo de la misma quedó demostrado, que una vez conocido el modelo geométrico tridimensional de un ensamble, la aplicación de criterios tecnológicos y geométricos al proceso inverso de desensamble y su posterior tratamiento con métodos evolutivos, genera planes deensamble mecánico próximos a los óptimos de acuerdo al sistema de preferencias del decisor. La integración de la información permite disminuir el número de secuencias a evaluar y de elementos a procesar, con lo que se evita la generación y evaluación de todas las secuencias posibles con la consecuente disminución del tiempo de procesamiento. Como resultado de la aplicación del modelo integrado propuesto, se obtiene la planificación del proceso de ensamblemecánico con una reducción del tiempo de ensamble debido a que en las secuencias obtenidas se reduce el número de cambios de dirección de ensamble, los cambios de herramientas y de puestos de trabajo, así como se minimiza la distancia a recorrer debido al cambio de puestos de trabajo. Esto se logra mediante un modelo de optimización multiobjetivo basado en algoritmos genéticos.This work deals with the combinatorial problem of generating and optimizing technologically feasible assembly sequences and process planning involving tools and work places. The assembly sequences and related technological decisions are obtained from a 3D model of the assembled parts based on mating conditions along with a set of technological criteria, which allows automatically analyzing and generating the sequences. The generated assembly sequences are pre-processed and optimized for the assembly Process Planning using Genetic Algorithms. This approach integrates the geometric and technological information of the assembly process, which allows reducing the number of elements and sequences to be processed with the consequent processing time and cost reduction.

    Full Text Available Valoramos por ecografía y estadísticamente la eficacia de la liposucción láser-asistida en casos de ginecomastia, teniendo en cuenta la respuesta de retracción de la piel, la rapidez de la recuperación del paciente, y el grado de satisfacción que originan los resultados. Presentamos un estudio prospectivo de 28 pacientes con ginecomastia de diferente grado, tratados mediante liposucción asistida por láser de Diodo de 1470 nm, previa sedación y con anestesia tumescente. El láser se programó a 15 Watios (W en emisión continua y se administraron 8 a 12 kilojulios (kJ por cada mama. No se realizaron escisiones de piel ni se emplearon drenajes. Se realizó valoración objetiva y subjetiva empleando la misma escala visual analógica (VAS completada por médicos y pacientes. Se tomaron fotografías antes y 6 meses después de la intervención, y se realizaron mediciones del perímetro torácico y del diámetro de las areolas. El seguimiento ecográfico de las áreas tratadas fue comparativo antes y 6 meses después del tratamiento. Para el estudio estadístico se empleó t de Student como test de contraste. No observamos complicaciones, como signos de isquemia o quemaduras cutáneas. La disminución del perímetro torácico y del diámetro de las areolas fue estadísticamente significativa. Tanto la valoración objetiva como la subjetiva alcanzaron resultados superiores al 90 %. Mediante la ecografía también se demostró disminución, estadísticamente significativa, de la banda de tejido graso subcutáneo (p < 0,05 al comparar las imágenes de antes y 6 meses después del tratamiento. La recuperación laboral se realizó en un promedio de 3 días. En conclusión, creemos que la liposucción láser-asistida es un método eficaz y reproducible, comprobado ecográfica y estadísticamente, que alcanza buenos resultados con menos trauma quirúrgico, lo que conlleva un alto grado de satisfacción por parte de los pacientes.

    Full Text Available Al abordar la legislación sobre Reproducción Humana Asistida, el legislador realiza una labor de mediación entre distintos derechos y principios que, en su pretensión de justicia, no está exenta de controversia. Tal labor no se realiza desde un punto de vista neutral, se han de tener en cuenta distintas opciones éticas e ideológicas propias de una sociedad democrática, sin abandonar la coherencia con el desarrollo de los distintos derechos humanos en juego, en definitiva, esa ética pública que configura los sistemas culturales, sociales y políticos: el derecho a la vida, a la dignidad, al libre desarrollo de la personalidad, a fundar una familia, a la intimidad personal y familiar, a la identidad, a la maternidad, a la salud, a la producción y creación científica y a gozar de los beneficios del progreso científico. Algunas Sentencias del Tribunal Europeo de Derechos Humanos y de la Corte Interamericana de Derechos Humanos inciden en estos derechos al tratar las Reproducción Humana Asistida, lo cual permite, más allá de las legislaciones concretas, esbozar algunos consensos sobre unas técnicas en constante evolución, como las sociedades en las que tales técnicas se ponen a disposición de sus ciudadanos.

    Full Text Available Resumen: El término Robots de Servicio apareció a finales de los años 80 como una necesidad de desarrollar máquinas y sistemas capaces de trabajar en entornos diferentes a los fabriles. Los Robots de Servicio tenían que poder trabajar en entornos noestructurados, en condiciones ambientales cambiantes y con una estrecha interacción con los humanos. En 1995 fue creado por la IEEE Robotics and Automation Society, el Technical Committee on Service Robots, y este comité definió en el año 2000 las áreas de aplicación de los Robots de Servicios, que se pueden dividir en dos grandes grupos: 1 sectores productivos no manufactureros tales como edificación, agricultura, naval, minería, medicina, etc. y 2 sectores de servicios propiamente dichos: asistencia personal, limpieza, vigilancia, educación, entretenimiento, etc. En este trabajo se hace una breve revisión de los principales conceptos y aplicaciones de los robots de servicio.

    Full Text Available El desarrollo de las Técnicas de Reproducción Humana Asistida (TRHA, supone una transformación fundamental en el modo concebir y tratar el cuerpo humano, que tiene por correlato importantes incidencias sobre la subjetividad. Este aspecto suele quedar en segundo plano frente a sus consecuencias para la conformación de la familia. En este artículo, en cambio, analizaremos los fundamentos filosóficos de la concepción del cuerpo en la que esta tecnología se sustenta, – y que, a su vez, las TRHA han contribuido a consolidar–, la cual tiene un inicio y una evolución en la historia del pensamiento occidental. Además, ya en pleno siglo XXI, con el espectacular desarrollo de la biomedicina, esa manera de concebir el cuerpo no sólo trae aparejados grandes cambios a nivel de la regulación jurídica, sino que tiene fuerte impacto sobre la subjetividad, según unas coordenadas que procuramos explorar en este artículo.

    Full Text Available The enormous development -in both research and application- of assisted reproduction technologies has been accompanied by a lack of theoretical reflection on its power of change: the concept and treatment of the body, the concept of paternity or motherhood, etc.The metaphorical analysis allows us to deconstruct both dominant discourses: patriarchal and reductionist biomedical. We propose a transdisciplinary analysis which explains the interactions between the diverse discourses: biomedical, mass media, legal, symbolicpsycho-social, gender, historic- which make up the supply as well as the creation of demand of all these practices. The transdisciplinary analysis would help to reveal the biomedical interests and the acritical spirit of the mass media, and would supply a true evaluation of the results, risks, success, or viability, etc of these technologies.

    Full Text Available Objetivos: La mayoría de trabajos sobre costes de las técnicas de reproducción asistida (TRA identifican el coste directo del procedimiento, sin considerar elementos como los costes estructurales o intermedios, de gran importancia. El objetivo de este trabajo es calcular el coste por proceso de las TRA realizadas en un hospital público en 2003 y compararlo con los resultados de 1998 en el mismo centro. Métodos: El estudio se realiza en la Unidad de Reproducción Humana (URH del Hospital Universitario Virgen de las Nieves de Granada en 1998 y 2003. Partiendo de los costes totales de dicha unidad, y mediante una metodología de distribución de costes basada en la estructura de costes, calculamos el coste por proceso de las TRA realizadas en este centro, considerando los costes completos. Resultados: Entre 1998 y 2003, la actividad y los costes de la URH analizada evolucionan de forma distinta. El análisis de la actividad muestra la consolidación de técnicas, como la microinyección espermática (ICSI y la desaparición de otras (ciclo sin reproducción asistida e inseminación artificial conyugal intracervical. En todos los procesos, los costes unitarios por ciclo y por embarazo disminuyen en el período analizado. Conclusiones: Se han producido importantes cambios en la estructura de costes de las TRA de la URH-HUVN entre 1998-2003. Mientras algunos procesos desaparecen, otros se consolidan con una elevada actividad. Los avances técnicos y las innovaciones organizativas, junto con un «efecto aprendizaje», han alterado la estructura de costes de las TRA.Objectives: Most studies on the costs of assisted reproductive technologies (ART identify the total cost of the procedure with the direct cost, without considering important items such as overhead or intermediate costs.

Al analizar el lugar de la R. A. en la agenda de grupos feministas mexicanos que trabajan en salud reproductiva, encontramos que la desmovilización y falta de discusión de una agenda común, la influencia del financiamiento en la definición de los asuntos que se priorizan, la resistencia a alejarse de los ejes de trabajo consagrados y la concepción de la maternidad como imposición, han llevado a que la R.

Los avances tecnológicos en los procedimientos de Cirugía Plástica han favorecido la obtención de buenos resultados evitando un trauma quirúrgico mayor y disminuyendo las complicaciones postoperatorias. En este sentido, el uso de la tecnología láser aplicado a la liposucción supuso una herramienta muy interesante e introdujo cambios sustanciales en la metodóloga y posibilidades de esta intervención. Presentamos nuestra experiencia con el uso del láser 980-nm y de una nueva tecnología de láser 1210-nm empleadas en combinación con la cirugía de lipoabdominoplastia Material y método. Realizamos un estudio retrospectivo en pacientes intervenidos con nuestro protocolo quirúrgico entre los años 2007 y 2014. Realizamos la lipoaspiración en un primer periodo con láser de 980-nm y posteriormente el de 1210-nm, previa a lipoabdominoplastia con técnica clásica y cicatriz reducida. Llevamos a cabo 101 lipoabdominoplastias, 47 con el láser 980-nm y 54 con el de 1210-nm, con un seguimiento postoperatorio de hasta 6 meses. Resultados. No evidenciamos quemaduras, tromboembolismos ni epidermólisis. Entre las complicaciones recogidas cuantificamos a los 14 días de postoperatorio 8 seromas en el grupo de láser 980 nm - cicatriz reducida (25% del total de casos del grupo y 2 casos en ambos grupos de cicatriz clásica (13.3 % de los casos del grupo de láser 980 nm - cicatriz clásica y 8.7% del grupo de láser 1210 nm - cicatriz clásica. Evidenciamos a los 2 meses de postoperatorio la formación de cicatrices hipertróficas en 3 casos, y a los 3 meses 1 cicatriz queloidea en los grupos de láser 1210 nm, correspondiendo 3 casos al grupo de cicatriz clásica y 1 caso al grupo de cicatriz reducida.

    Full Text Available El presente trabajo versa sobre la generación, planificación y optimización de secuencias de ensamble mecánico a partir de su modelo geométrico tridimensional. Se soporta sobre un enfoque que integra tanto información geométrica como restricciones tecnológicas del proceso de ensamble. En el desarrollo de la misma quedó demostrado, que una vez conocido el modelo geométrico tridimensional de un ensamble, la aplicación de criterios tecnológicos y geométricos al proceso inverso de desensamble y su posterior tratamiento con el método de algoritmos evolutivos, genera una planificación optimizada del su proceso de ensamble mecánico. La integración de la información permite disminuir el número de secuencias a evaluar y de elementos a procesar, con lo que se evita la generación y evaluación de todas las secuencias posibles con la consecuente disminución del tiempo de procesamiento. Como resultado de la aplicación del modelo integrado propuesto, se obtiene la planificación del proceso de ensamble mecánico con una reducción del tiempo de ensamble debido a que en las secuencias de ensamble obtenidas se reduce el número de cambios de dirección de ensamble, los cambios de herramientas y de puestos de trabajo, así como se minimiza la distancia a recorrer debido al cambio de puestos de trabajo. Esto se logra mediante un modelo de optimización multiobjetivo basado en algoritmos evolutivos.This work deals with the combinatorial problem of generating and optimizing feasible assembly sequences and doing the process planning involving tools and work places. The assembly sequences are obtained from a 3D model of the assembled parts based on mating conditions along with a set of technological criteria, which allows automatically analyzing and generating the sequences. The generated assembly sequences are preprocessed and optimized for the assembly Process Planning using Genetic Algorithms. This approach integrates the geometric and technological information of the assembly process, which allows reducing the number of elements and sequences to be processed with the consequent processing time and cost reduction.

    We developed a new process for the synthesis of SiC whiskers assisted by microwaves; this is based on the mixture of silica xerogels and graphite powder. As energy source were used microwaves of 2.45 GHz and 1.0 kW of power RMS. On the other hand, mesoporous silica was synthesized via sol-gel, the precursors used were TEOS/H{sub 2}O and ethanol. Through analysis of the BET is determined the value of average pore size (3.0 nm) and the surface area (1090 m2/g).By mean of X-Ray diffraction it was demonstrated that the silica obtained is an amorphous solid and, the powders obtained in the microwave synthesis are {beta}-SiC. Synthesized SiC powders were observed using a SEM in secondary electron mode, it was observed that this powders consists of SiC whiskers. The effect of microwaves on the synthesis of whiskers of SiC is discussed in the present work. (Author) 19 refs.

    This article proposes quantitative evaluation metrics of imitation, suited for the imitation of four gestures performed by a robotic arm on a simulation environment; for each gesture, the metric relies on a group of simple geometric shapes. This approach broadens the concept of imitation; since common metrics just accumulate the error between the joints of the demonstrator and the imitator along their trajectories, in other words, check for the exact replica of the gesture performed by the demonstrator. The results of the proposed metric are compared with an evaluation survey. (Author) 11 refs.

    Full Text Available En este artículo se analizan los debates parlamentarios de la Ley 26743 de Identidad de Género y de la Ley 26862 de Fertilización Asistida, desarrollados en el Congreso Nacional argentino entre los años 2011 y 2013. A través de la técnica de análisis de contenido cualitativo se analizan las versiones taquigráficas de los debates parlamentarios con el fin de responder los siguientes interrogantes: ¿cómo fue caracterizado el problema público al cual ambas leyes darían respuesta?, ¿cómo fue conceptualizada la misión de ambas leyes?, ¿en qué medida dicha definición implicó poner en entredicho las nociones de salud y enfermedad con relación a la cobertura de tratamientos de optimización o modificación corporal por parte del sistema público de salud? El proceso de sanción de ambas leyes implicó tensionar los conceptos de salud y enfermedad como categorías morales. En dicho marco emergió una noción ampliada del concepto de salud integral que incluyó los deseos reproductivos y corporales de los ciudadanos y ciudadanas.

    Robots are simultaneously real machines and technical images that challenge our sense of self. In the Open Forum I discuss the movie Ex Machina by director Alex Garland. The robot Ava, played by Alicia Vikander, is a rare portrait of what could be interpreted as a feminist robot (and...... there are spoilers ahead for any readers unfamiliar with this movie). Though she apparently is created as the dream of the ‘perfect woman’, sexy and beautiful, she also develops and urges to free herself from the slavery of her creator, Nathan Bateman. She is a robot created along the perfect dimensions...... as a Vitruvian robot but is also a creature which could be interpreted as a human being. However, the point I want to raise is not whether Ava’s reaction to robot slavery is justified or not but how her portrait raises questions about the blurred lines between reality and fiction when we discuss our robotic...

    Proficiency in minimally invasive surgery requires intensive and continuous training, as it is technically challenging for unnatural visual and haptic perceptions. Robotic and computer sciences are producing innovations to augment the surgeon's skills to achieve accuracy and high precision during complex surgery. This article reviews the current use of robotically assisted surgery, focusing on technology as well as main applications in digestive surgery, and future perspectives. The PubMed database was interrogated to retrieve evidence-based data on surgical applications. Internal and external consulting with key opinion leaders, renowned robotics laboratories and robotic platform manufacturers was used to produce state-of-the art business intelligence around robotically assisted surgery. Selected digestive procedures (oesophagectomy, gastric bypass, pancreatic and liver resections, rectal resection for cancer) might benefit from robotic assistance, although the current level of evidence is insufficient to support widespread adoption. The surgical robotic market is growing, and a variety of projects have recently been launched at both academic and corporate levels to develop lightweight, miniaturized surgical robotic prototypes. The magnified view, and improved ergonomics and dexterity offered by robotic platforms, might facilitate the uptake of minimally invasive procedures. Image guidance to complement robotically assisted procedures, through the concepts of augmented reality, could well represent a major revolution to increase safety and deal with difficulties associated with the new minimally invasive approaches. © 2015 BJS Society Ltd.

One of the company's major projects is construction of a huge Field Material Handling Robot for the Army's Human Engineering Lab. Design of FMR, intended to move heavy and dangerous material such as ammunition, was a triumph in CAD Engineering. Separate computer problems modeled the robot's kinematics and dynamics, yielding such parameters as the strength of materials required for each component, the length of the arms, their degree of freedom and power of hydraulic system needed. The Robotics Lab went a step further and added data enabling computer simulation and animation of the robot's total operational capability under various loading and unloading conditions. NASA computer program (IAC), integrated Analysis Capability Engineering Database was used. Program contains a series of modules that can stand alone or be integrated with data from sensors or software tools.

    Medicine has experienced greater scientific and technological advances in the last 50 years than in the rest of human history. The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient. The objective of the surgical robot is to correct human deficiencies and improve surgical skills. The capacity of repeating tasks with precision and reproducibility has been the base of the robot´s success. Robotic technology offers objective and measurable advantages: - Improving maneuverability and physical capacity during surgery. - Correcting bad postural habits and tremor. - Allowing depth perception (3D images). - Magnifying strength and movement limits. - Offering a platform for sensors, cameras, and instruments. Endoscopic surgery transformed conceptually the way of practicing surgery. Nevertheless in the last decade, robotic assisted surgery has become the next paradigm of our era.

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

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

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

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

    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.

Los bajos niveles de eficiencia que muchos administradores de sistemasde distribución de agua (ASDA exhiben tienden a agudizar este problema. A través de herramientas de modelación asistida de sistemas de distribución de agua (MASDA, es posible generar un mayor conocimiento sobre la naturaleza y posibilidades de cada sistema. Como caso de estudio, CIVCO/ITCR, analizó la situación del sistema de distribución de agua potable del campo/escuela Scout de Costa Rica. Al identificarse deficiencias irremediables, se decidió diseñar un nuevo sistema que pueda afrontar adecuadamente una ocupación máxima de 280 personas durante un evento crítico de 8 días. Una vez definidos los patrones de diseño, se evalúan diversos escenarios de modelación a través de EPANet 2.0. La información arrojadaindica que los supuestos originales de diseño son adecuados y el sistema presenta condiciones estables de flujo uniforme durante todo el período de modelación. Por otro lado, la concentración de cloro residual en el sistema llega a estabilizarse después de pasado del período de ocupación máxima. El proyecto MASDA seguirá prestando en el futuro asesoramiento y apoyo tecnológico a los administradores de sistemas de distribución de agua, y les permitirá servir de una forma eficiente, constante y confiable a las comunidades bajo su administración, al tiempo que se reduce el impacto sobre las fuentes de producción.

    This paper summarizes the research results on the friendly network robotics in fiscal 1996. This research assumes an android robot as an ultimate robot and the future robot system utilizing computer network technology. The robot aiming at human daily work activities in factories or under extreme environments is required to work under usual human work environments. The human robot with similar size, shape and functions to human being is desirable. Such robot having a head with two eyes, two ears and mouth can hold a conversation with human being, can walk with two legs by autonomous adaptive control, and has a behavior intelligence. Remote operation of such robot is also possible through high-speed computer network. As a key technology to use this robot under coexistence with human being, establishment of human coexistent robotics was studied. As network based robotics, use of robots connected with computer networks was also studied. In addition, the R-cube (R{sup 3}) plan (realtime remote control robot technology) was proposed. 82 refs., 86 figs., 12 tabs.

    Full Text Available Resumen: En este trabajo se presenta una interfaz especialmente diseñada para la navegación de una silla de ruedas robotizada dentro de entornos restringidos. El funcionamiento de la interfaz se rige por dos modos: un modo autónomo y un modo no-autónomo. El manejo no-autónomo de la interfaz de la silla de ruedas se realiza por medio de un joystick adecuado a las capacidades del usuario el cual gobierna el movimiento del vehículo dentro del ambiente. El modo autónomo de la silla de ruedas se ejecuta cuando el usuario tiene que girar un determinado ángulo dentro del ambiente. La estrategia de giro se ejecuta mediante un algoritmo de maniobrabilidad compatible con la cinemática del vehículo y mediante el uso del algoritmo de SLAM (por sus siglas en inglés de Simultaneous Localization and Mapping. El modo autónomo se compone de dos módulos: un módulo de planificación de caminos y un módulo de control. El módulo de planificación de caminos usa la información del mapa provista por el algoritmo de SLAM para trazar un camino seguro y compatible con la silla de ruedas, que le permita al vehículo alcanzar la orientación deseada. El módulo de control gobierna el movimiento del vehículo en el seguimiento del camino trazado mediante un controlador de seguimiento de trayectorias. Las referencias del controlador son actualizadas mediante la estimación de la postura de la silla de ruedas dentro del ambiente, obtenida por el algoritmo de SLAM.

    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

    Robotic surgery is rapidly evolving and has become an essential part of surgical practice in several parts of the world. Robotic technology will expand globally and most of the surgeons around the world will have access to surgical robots in the future. It is essential that we are updated about the outcomes of robot assisted surgeries which will allow everyone to develop an unbiased opinion on the clinical utility of this innovation. In this review we aim to present the evolution, objective evaluation of clinical outcomes and future perspectives of robot assisted urologic surgeries. A systematic literature review of clinical outcomes of robotic urological surgeries was made in the PUBMED. Randomized control trials, cohort studies and review articles were included. Moreover, a detailed search in the web based search engine was made to acquire information on evolution and evolving technologies in robotics. The present evidence suggests that the clinical outcomes of the robot assisted urologic surgeries are comparable to the conventional open surgical and laparoscopic results and are associated with fewer complications. However, long term results are not available for all the common robotic urologic surgeries. There are plenty of novel developments in robotics to be available for clinical use in the future. Robotic urologic surgery will continue to evolve in the future. We should continue to critically analyze whether the advances in technology and the higher cost eventually translates to improved overall surgical performance and outcomes. Copyright © 2014 AEU.

    Full Text Available Pelvic organ prolapse (POP is a prevalent condition with 1 in 9 women seeking surgical treatment by the age of 80 years. Goals of treatment are relief and prevention of symptoms, and restoration of pelvic floor support. The gold standard for surgical treatment of POP has been abdominal sacrocolpopexy (ASC. However, emerging technologies have allowed for more minimally invasive approach including the use of laparoscopic assisted sacrocolpopexy and robotic assisted sacrocolpopexy (RASC. We performed a PubMed literature search for sacrocolpopexy, "robotic sacrocolpopexy" and "RASC" and reviewed all retrospective, prospective and randomized controlled trials. The techniques, objective and subjective outcomes and complications are discussed. The most frequent technique involves a polypropylene Y mesh attached to the anterior and posterior walls of the vagina with the single arm attached to the sacrum. Multiple concomitant procedures have been described including hysterectomy, anti-incontinence procedures and concomitant vaginal prolapse repairs. There are few studies comparing RASC to ASC, with the longest follow-up data showing no difference in subjective and objective outcomes. Anatomic success rates have been reported at 79-100% with up to 9% of patients requiring successive surgery for recurrence. Subjective success is poorly defi ned, but has been reported at 88-97%. Most common complications are urinary retention, urinary tract infection, bladder injury and vaginal mucosal injury. Mesh exposure is reported in up to 10% of patients. RASC allows for a minimally invasive approach to treatment of POP with comparable outcomes and low complication rates.

  14. Hexapod Robot

    2016-01-01

    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

    2009-11-17

    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.

    2012-04-01

    Full Text Available A pesar de los cambios políticos, socio-económicos y demográficos habidos en los países occidentales en las últimas décadas, las estructuras simbólicas y los imaginarios colectivos en torno a las mujeres, su función social y la maternidad no han cambiado tanto. El orden patriarcal hoy en Occidente se configura como un patriarcado de consentimiento. En dicha estructura social la retórica ideológica representa la maternidad como una elección. Sin embargo, a través de los universos simbólicos que ofrecen los medios de comunicación de masas, la maternidad sigue perfilándose como un mandato imperativo para la construcción de la identidad femenina. En este estudio vamos a tomar como ejemplo la película Madre de alquiler, representación fílmica sobre la maternidad y las técnicas de reproducción asistida que refrenda el mandato patriarcal de la maternidad.

    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.

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

    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. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2008-11-01

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

  7. Space Robotics: Robotic Rovers for Planetary Exploration

    2008-11-01

    Full Text Available In this third of three short papers, I introduce some of the basic concepts of planetary rovers with an emphasis on some specific challenging areas of research that are peculiar to planetary robotics and not usually associated with terrestrial mobile robotics. The style of these short papers is pedagogical and this paper stresses the issue of rover-terrain interaction as an important consideration. Soil-vehicle interaction originates from military vehicle research but may be regarded as part of the dynamical approach to mobile robotics. For hostile planetary surfaces, this is essential in order to design a robotic rover with sufficient tractive capability to traverse planetary surfaces.

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

    2014-01-01

    The purpose of this review is to compare conventional endovascular procedures and the robotic endovascular approach in aortic aneurysm repair. Despite advantages over open surgery, conventional endovascular surgery has limitations. To develop an alternative, efforts have been focused on robotic endovascular systems. Two of the 3 studies comparing procedure times demonstrated reduced procedure time in the robotic group, by 6 times (p robotic procedures reduced fluoroscopic exposure time by 12 minute (p robotic surgery was reduced up to 10 times (p robotic performance score showed a better performance score in the robotic endovascular group (p = 0.007). These results demonstrate that the robotic technique has multiple advantages over the conventional procedure, including improved catheter stability, a shorter learning curve, reduced procedure time, and better performance in cannulating tortuous vessels. However, robotic endovascular technology may be limited by the cost of the system, the size of the catheter, and the setup time required preoperatively. Further comparative studies between conventional and robotic approaches regarding cost-effectiveness, safety, and performance in cases involving complex anatomy and fenestrated stent grafts are essential. Nevertheless, this revolutionary technology is increasingly popular and may be the next milestone in endovascular surgery.

    2009-08-01

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

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

    Robotic surgery has evolved over the last decade to compensate for limitations in human dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations. The nature of the robotic assistance varies from voice activated camera control to more elaborate telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a voice activated camera control system.

    2015-01-01

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

    2013-12-01

    This topic is part of the global issue concerning the necessity to adapt intellectual property law to constant changes in technology. The relationship between robots and IP is dual. On one hand, the robots may be regarded as objects of intellectual property. A robot, like any new machine, could qualify for a protection by a patent. A copyright may protect its appearance if it is original. Its memory, like a database, could be covered by a sui generis right. On the other hand, the question of the protection of the outputs of the robot must be raised. The robots, as the physical embodiment of artificial intelligence, are becoming more and more autonomous. Robot-generated works include less and less human inputs. Are these objects created or invented by a robot copyrightable or patentable? To whom the ownership of these IP rights will be allocated? To the person who manufactured the machine ? To the user of the robot? To the robot itself? All these questions are worth discussing.

    A small prototype mobile robot is capable of (1) hopping to move rapidly or avoid obstacles and then (2) moving relatively slowly and precisely on the ground by use of wheels in the manner of previously reported exploratory robots of the "rover" type. This robot is a descendant of a more primitive hopping robot described in "Minimally Actuated Hopping Robot" (NPO- 20911), NASA Tech Briefs, Vol. 26, No. 11 (November 2002), page 50. There are many potential applications for robots with hopping and wheeled-locomotion (roving) capabilities in diverse fields of endeavor, including agriculture, search-and-rescue operations, general military operations, removal or safe detonation of land mines, inspection, law enforcement, and scientific exploration on Earth and remote planets. The combination of hopping and roving enables this robot to move rapidly over very rugged terrain, to overcome obstacles several times its height, and then to position itself precisely next to a desired target. Before a long hop, the robot aims itself in the desired hopping azimuth and at a desired takeoff angle above horizontal. The robot approaches the target through a series of hops and short driving operations utilizing the steering wheels for precise positioning.

    The Canadian Space Agency has chosen space robotics as one of its key niche areas, and is currently preparing to deliver the first flight elements for the main robotic system of the international space station. The Mobile Servicing System (MSS) is the Canadian contribution to the international space station. It consists of three main elements. The Space Station Remote Manipulator System (SSRMS) is a 7-metre, 7-dof, robotic arm. The Special Purpose Dextrous Manipulator (SPDM), a smaller 2-metre, 7-dof, robotic arm can be used independently, or attached to the end of the SSRMS. The Mobile Base System (MBS) will be used as a support platform and will also provide power and data links for both the SSRMS and the SPDM. A Space Vision System (SVS) has been tested on Shuttle flights, and is being further developed to enhance the autonomous capabilities of the MSS. The CSA also has a Strategic Technologies in Automation and Robotics Program which is developing new technologies to fulfill future robotic space mission needs. This program is currently developing in industry technological capabilities in the areas of automation of operations, autonomous robotics, vision systems, trajectory planning and object avoidance, tactile and proximity sensors, and ground control of space robots. Within the CSA, a robotic testbed and several research programs are also advancing technologies such as haptic devices, control via head-mounted displays, predictive and preview displays, and the dynamic characterization of robotic arms. Canada is also now developing its next Long Term Space Plan. In this context, a planetary exploration program is being considered, which would utilize Canadian space robotic technologies in this new arena.

    Klibansky, David; Rothstein, Richard I

    2012-09-01

    The increasing complexity of intralumenal and emerging translumenal endoscopic procedures has created an opportunity to apply robotics in endoscopy. Computer-assisted or direct-drive robotic technology allows the triangulation of flexible tools through telemanipulation. The creation of new flexible operative platforms, along with other emerging technology such as nanobots and steerable capsules, can be transformational for endoscopic procedures. In this review, we cover some background information on the use of robotics in surgery and endoscopy, and review the emerging literature on platforms, capsules, and mini-robotic units. The development of techniques in advanced intralumenal endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and translumenal endoscopic procedures (NOTES) has generated a number of novel platforms, flexible tools, and devices that can apply robotic principles to endoscopy. The development of a fully flexible endoscopic surgical toolkit will enable increasingly advanced procedures to be performed through natural orifices. The application of platforms and new flexible tools to the areas of advanced endoscopy and NOTES heralds the opportunity to employ useful robotic technology. Following the examples of the utility of robotics from the field of laparoscopic surgery, we can anticipate the emerging role of robotic technology in endoscopy.

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

    In this paper, an articulated type of industrial used robot is discussed. The robot is mainly intended to be used in pick and place operation. It will sense the object at the specified place and move it to a desired location. A peripheral interface controller (PIC16F84A) is used as the main controller of the robot. Infrared LED and IR receiver unit for object detection and 4-bit bidirectional universal shift registers (74LS194) and high current and high voltage Darlington transistors arrays (ULN2003) for driving the arms' motors are used in this robot. The amount of rotation for each arm is regulated by the limit switches. The operation of the robot is very simple but it has the ability of to overcome resetting position after power failure. It can continue its work from the last position before the power is failed without needing to come back to home position.

    Robots have been successfully used in commercial industry and have enabled humans to perform tasks which are repetitive, dangerous and requiring extreme force. Their role has evolved and now includes many aspects of surgery to improve safety and precision. Orthopaedic surgery is largely performed on bones which are rigid immobile structures which can easily be performed by robots with great precision. Robots have been designed for use in orthopaedic surgery including joint arthroplasty and spine surgery. Experimental studies have been published evaluating the role of robots in arthroscopy and trauma surgery. In this article, we will review the incorporation of robots in orthopaedic surgery looking into the evidence in their use. © The Authors, published by EDP Sciences, 2017.

The style of these short papers is pedagogical and this paper stresses the unique constraints that space application imposes. This first paper is thus a general introduction to the nature of spacecraft engineering and its application to robotic spacecraft. I consider the constraints and metrics used by spacecraft engineers in the design of spacecraft and how these constraints impose challenges to the roboticist. The following two papers consider specific robotics issues in more detail.

  8. Low impedance walking robots.

    Science.gov (United States)

    Pratt, Gill Andrews

    2002-02-01

    For both historical and technological reasons, most robots, including those meant to mimic animals or operate in natural environments,3 use actuators and control systems that have high (stiff) mechanical impedance. By contrast, most animals exhibit low (soft) impedance. While a robot's stiff joints may be programmed to closely imitate the recorded motion of an animal's soft joints, any unexpected position disturbances will generate reactive forces and torques much higher for the robot than for the animal. The dual of this is also true: while an animal will react to a force disturbance by significantly yielding position, a typical robot will greatly resist.These differences cause three deleterious effects for high impedance robots. First, the higher forces may cause damage to the robot or to its environment (which is particularly important if that environment includes people). Second, the robot must acquire very precise information about its position relative to the environment so as to minimize its velocity upon impact. Third, many of the self-stabilizing effects of natural dynamics are "shorted out"4 by the robot's high impedance, so that stabilization requires more effort from the control system.Over the past 5 yr, our laboratory has designed a series of walking robots based on "Series-Elastic Actuators" and "Virtual Model Control." Using these two techniques, we have been able to build low-impedance walking robots that are both safe and robust, that operate blindly without any model of upcoming terrain, and that add minimal control effort in parallel to their self-stabilizing passive dynamics. We have discovered that it is possible to achieve surprisingly effective ambulation from rather simple mechanisms and control systems. After describing the historical and technological motivations for our approach, this paper gives an overview of our methods and shows some of the results we have obtained.

    2014-01-01

    Although many features of robotic prostatectomy are similar to those of conventional laparoscopic urological procedures (such as laparoscopic prostatectomy), the procedure is associated with some drawbacks, which include limited intravenous access, relatively long operating time, deep Trendelenburg position, and high intra-abdominal pressure. The primary aim was to describe respiratory and hemodynamic challenges and the complications related to high intra-abdominal pressure and the deep Trendelenburg position in robotic prostatectomy patients. The secondary aim was to reveal safe discharge criteria from the operating room. Fifty-three patients who underwent robotic prostatectomy between December 2009 and January 2011 were prospectively enrolled. Main outcome measures were non-invasive monitoring, invasive monitoring and blood gas analysis performed at supine (T0), Trendelenburg (T1), Trendelenburg + pneumoperitoneum (T2), Trendelenburg-before desufflation (T3), Trendelenburg (after desufflation) (T4), and supine (T5) positions. Fifty-three robotic prostatectomy patients were included in the study. The main clinical challenge in our study group was the choice of ventilation strategy to manage respiratory acidosis, which is detected through end-tidal carbon dioxide pressure and blood gas analysis. Furthermore, the mean arterial pressure remained unchanged, the heart rate decreased significantly and required intervention. The central venous pressure values were also above the normal limits. Respiratory acidosis and "upper airway obstruction-like" clinical symptoms were the main challenges associated with robotic prostatectomy procedures during this study.

    Lendvay, Thomas Sean; Hannaford, Blake; Satava, Richard M

    2013-01-01

    In just over a decade, robotic surgery has penetrated almost every surgical subspecialty and has even replaced some of the most commonly performed open oncologic procedures. The initial reports on patient outcomes yielded mixed results, but as more medical centers develop high-volume robotics programs, outcomes appear comparable if not improved for some applications. There are limitations to the current commercially available system, and new robotic platforms, some designed to compete in the current market and some to address niche surgical considerations, are being developed that will change the robotic landscape in the next decade. Adoption of these new systems will be dependent on overcoming barriers to true telesurgery that range from legal to logistical. As additional surgical disciplines embrace robotics and open surgery continues to be replaced by robotic approaches, it will be imperative that adequate education and training keep pace with technology. Methods to enhance surgical performance in robotics through the use of simulation and telementoring promise to accelerate learning curves and perhaps even improve surgical readiness through brief virtual-reality warm-ups and presurgical rehearsal. All these advances will need to be carefully and rigorously validated through not only patient outcomes, but also cost efficiency.

    Laird, John E.

    2009-05-01

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

    An architecture for robot intelligence enables a robot to learn new behaviors and create new behavior sequences autonomously and interact with a dynamically changing environment. Sensory information is mapped onto a Sensory Ego-Sphere (SES) that rapidly identifies important changes in the environment and functions much like short term memory. Behaviors are stored in a DBAM that creates an active map from the robot's current state to a goal state and functions much like long term memory. A dream state converts recent activities stored in the SES and creates or modifies behaviors in the DBAM.

    2013-12-01

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

    2014-01-01

    The remarkable advances of robotics in the last 50 years, which represent an incredible wealth of knowledge, are based on the fundamental assumption that robots are chains of rigid links. The use of soft materials in robotics, driven not only by new scientific paradigms (biomimetics, morphological computation, and others), but also by many applications (biomedical, service, rescue robots, and many more), is going to overcome these basic assumptions and makes the well-known theories and techniques poorly applicable, opening new perspectives for robot design and control. The current examples of soft robots represent a variety of solutions for actuation and control. Though very first steps, they have the potential for a radical technological change. Soft robotics is not just a new direction of technological development, but a novel approach to robotics, unhinging its fundamentals, with the potential to produce a new generation of robots, in the support of humans in our natural environments.

    Intelligent system and robotics are inevitably bound up; intelligent robots makes embodiment of system integration by using the intelligent systems. We can figure out that intelligent systems are to cell units, while intelligent robots are to body components. The two technologies have been synchronized in progress. Making leverage of the robotics and intelligent systems, applications cover boundlessly the range from our daily life to space station; manufacturing, healthcare, environment, energy, education, personal assistance, logistics. This book aims at presenting the research results in relevance with intelligent robotics technology. We propose to researchers and practitioners some methods to advance the intelligent systems and apply them to advanced robotics technology. This book consists of 10 contributions that feature mobile robots, robot emotion, electric power steering, multi-agent, fuzzy visual navigation, adaptive network-based fuzzy inference system, swarm EKF localization and inspection robot.

    Beck, Anders Billesø

    Mobile robots have become a mature technology. The first cable guided logistics robots were introduced in the industry almost 60 years ago. In this time the market for mobile robots in industry has only experienced a very modest growth and only 2.100 systems were sold worldwide in 2011. In recent...... years, many other domains have adopted the mobile robots, such as logistics robots at hospitals and the vacuum robots in our homes. However, considering the achievements in research the last 15 years within perception and operation in natural environments together with the reductions of costs in modern...... sensor systems, the growth potential for mobile robot applications are enormous. Many new technological components are available to move the limits of commercial mobile robot applications, but a key hindrance is reliability. Natural environments are complex and dynamic, and thus the risk of robots...

    Soft robotics and its related technologies enable robot abilities in several robotics domains including, but not exclusively related to, manipulation, manufacturing, human-robot interaction and locomotion. Although field applications have emerged for soft manipulation and human-robot interaction, mobile soft robots appear to remain in the research stage, involving the somehow conflictual goals of having a deformable body and exerting forces on the environment to achieve locomotion. This paper aims to provide a reference guide for researchers approaching mobile soft robotics, to describe the underlying principles of soft robot locomotion with its pros and cons, and to envisage applications and further developments for mobile soft robotics. © 2017 The Author(s).

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

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

    2015-01-01

    Robotic surgery was initially developed to overcome problems faced during conventional laparoscopic surgeries and to perform telesurgery at distant locations. It has now established itself as the epitome of minimally invasive surgery (MIS). It is one of the most significant advances in MIS in recent years and is considered by many as a revolutionary technology, capable of influencing the future of surgery. After its introduction to urology, robotic surgery has redefined the management of urological malignancies. It promises to make difficult urological surgeries easier, safer and more acceptable to both the surgeon and the patient. Robotic surgery is slowly, but surely establishing itself in India. In this article, we provide an overview of the advantages, disadvantages, current status, and future applications of robotic surgery for urologic cancers in the context of the Indian scenario.

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

  19. Colias: An Autonomous Micro Robot for Swarm Robotic Applications

    2014-07-01

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

  20. Swarm robotics and minimalism

    Science.gov (United States)

    Sharkey, Amanda J. C.

    2007-09-01

    Swarm Robotics (SR) is closely related to Swarm Intelligence, and both were initially inspired by studies of social insects. Their guiding principles are based on their biological inspiration and take the form of an emphasis on decentralized local control and communication. Earlier studies went a step further in emphasizing the use of simple reactive robots that only communicate indirectly through the environment. More recently SR studies have moved beyond these constraints to explore the use of non-reactive robots that communicate directly, and that can learn and represent their environment. There is no clear agreement in the literature about how far such extensions of the original principles could go. Should there be any limitations on the individual abilities of the robots used in SR studies? Should knowledge of the capabilities of social insects lead to constraints on the capabilities of individual robots in SR studies? There is a lack of explicit discussion of such questions, and researchers have adopted a variety of constraints for a variety of reasons. A simple taxonomy of swarm robotics is presented here with the aim of addressing and clarifying these questions. The taxonomy distinguishes subareas of SR based on the emphases and justifications for minimalism and individual simplicity.

  1. Multi-robot caravanning

    Denny, Jory

    2013-11-01

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

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

    2013-01-01

    The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy, unparalleled to any previous visual loop or magnification techniques. This technology revolutionized techniques for microsurgery in andrology. Today, we may be on the verge of a second such revolution by the incorporation of robotic assisted platforms for microsurgery in andrology. Robotic assisted microsurgery is being utilized to a greater degree in andrology and a number of other microsurgical fields, such as ophthalmology, hand surgery, plastics and reconstructive surgery. The potential advantages of robotic assisted platforms include elimination of tremor, improved stability, surgeon ergonomics, scalability of motion, multi-input visual interphases with up to three simultaneous visual views, enhanced magnification, and the ability to manipulate three surgical instruments and cameras simultaneously. This review paper begins with the historical development of robotic microsurgery. It then provides an in-depth presentation of the technique and outcomes of common robotic microsurgical andrological procedures, such as vasectomy reversal, subinguinal varicocelectomy, targeted spermatic cord denervation (for chronic orchialgia) and robotic assisted microsurgical testicular sperm extraction (microTESE).

    2018-01-01

    Uterine fibroids are the most common tumors of the uterus and the female pelvis and are associated with substantial morbidity for several women. In women with a wish to preserve fertility, a myomectomy is the surgical procedure of choice when medical therapy is inadequate. Despite evidence that minimally invasive surgery is preferable to laparotomy, most myomectomies are still performed by laparotomy. Robotic surgery was introduced to overcome some of the difficulties associated with laparoscopic surgery. A myomectomy is a suture-intensive surgery where the properties of a surgical robot have been suggested to be of particular value. Robotic myomectomy is feasible and safe, with similar outcome to laparoscopic surgery, although a robotic procedure is associated with a higher cost. The introduction of robotic surgery has expanded the indications for minimally invasive myomectomy to more complex cases previously performed by laparotomy. Randomized trials comparing different approaches to myomectomy are yet to be published. More studies are needed to determine the patients in whom a robotic approach is most beneficial, both in terms of patient outcomes and cost efficiency. Copyright © 2017. Published by Elsevier Ltd.

    2004-01-01

    With the advent of significant collaborations between researchers who study insect walking and robotics engineers interested in constructing adaptive legged robots, insect walking is once again poised to make a more significant scientific contribution than the numbers of participants in the field might suggest. This review outlines current knowledge of the physiological basis of insect walking with an emphasis on recent new developments in biomechanics and genetic dissection of behavior, and the impact this knowledge is having on robotics. Engineers have begun to team with neurobiologists to build walking robots whose physical design and functional control are based on insect biology. Such an approach may have benefits for engineering, by leading to the construction of better-performing robots, and for biology, by allowing real-time and real-world tests of critical hypotheses about how locomotor control is effected. It is argued that in order for the new field of biorobotics to have significant influence it must adopt criteria for performance and an experimental approach to the development of walking robots.

  19. Robots for Astrobiology!

    Boston, Penelope J.

    2016-01-01

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

    2013-01-01

    The Basic Operational Robotics Instructional System (BORIS) is a six-degree-of-freedom rotational robotic manipulator system simulation used for training of fundamental robotics concepts, with in-line shoulder, offset elbow, and offset wrist. BORIS is used to provide generic robotics training to aerospace professionals including flight crews, flight controllers, and robotics instructors. It uses forward kinematic and inverse kinematic algorithms to simulate joint and end-effector motion, combined with a multibody dynamics model, moving-object contact model, and X-Windows based graphical user interfaces, coordinated in the Trick Simulation modeling environment. The motivation for development of BORIS was the need for a generic system for basic robotics training. Before BORIS, introductory robotics training was done with either the SRMS (Shuttle Remote Manipulator System) or SSRMS (Space Station Remote Manipulator System) simulations. The unique construction of each of these systems required some specialized training that distracted students from the ideas and goals of the basic robotics instruction.

  4. Rehearsal for the Robot Revolution

    Jochum, Elizabeth; Goldberg, Ken

    This paper considers the use of tele-operated and autonomous robots in live performance. Theatre is a conducive to studying what makes robots compelling and engaging. Because theatre is a narrowly defined domain in which robots can excel, it is a useful test bed for exploring issues...... that are central to social robotics. However automated performances that merely substitute robotic actors for human ones do not always capture our imagination or prove entertaining. While some plays explore ambivalence to robots or “misbehaving machines” thematically (such as R.U.R.), the exigencies of live...... theatre do not allow for editing or special effects. Unlike film, robots onstage must be highly calibrated and run the risk of appearing like over-rehearsed actors.

    This paper discusses the role of robots in remote education. There are three different aims of robot edutainment, i.e., Learning on Robots, Learning through Robots, and Learning with Robots. The last is to apply human-friendly robots instead of personal computers for computer-assisted instruction. Especially, natural communication capability is required to educational robots in the learning with robots. In this paper, we apply human-friendly robots to remote education and discuss the requirements and specifications of robots for the remote education.

  10. Robotics, Ethics, and Nanotechnology

    Science.gov (United States)

    Ganascia, Jean-Gabriel

    It may seem out of character to find a chapter on robotics in a book about nanotechnology, and even more so a chapter on the application of ethics to robots. Indeed, as we shall see, the questions look quite different in these two fields, i.e., in robotics and nanoscience. In short, in the case of robots, we are dealing with artificial beings endowed with higher cognitive faculties, such as language, reasoning, action, and perception, whereas in the case of nano-objects, we are talking about invisible macromolecules which act, move, and duplicate unseen to us. In one case, we find ourselves confronted by a possibly evil double of ourselves, and in the other, a creeping and intangible nebula assails us from all sides. In one case, we are faced with an alter ego which, although unknown, is clearly perceptible, while in the other, an unspeakable ooze, the notorious grey goo, whose properties are both mysterious and sinister, enters and immerses us. This leads to a shift in the ethical problem situation: the notion of responsibility can no longer be worded in the same terms because, despite its otherness, the robot can always be located somewhere, while in the case of nanotechnologies, myriad nanometric objects permeate everywhere, disseminating uncontrollably.

  11. Biologically inspired intelligent robots

    2003-07-01

    Humans throughout history have always sought to mimic the appearance, mobility, functionality, intelligent operation, and thinking process of biological creatures. This field of biologically inspired technology, having the moniker biomimetics, has evolved from making static copies of human and animals in the form of statues to the emergence of robots that operate with realistic behavior. Imagine a person walking towards you where suddenly you notice something weird about him--he is not real but rather he is a robot. Your reaction would probably be "I can't believe it but this robot looks very real" just as you would react to an artificial flower that is a good imitation. You may even proceed and touch the robot to check if your assessment is correct but, as oppose to the flower case, the robot may be programmed to respond physical and verbally. This science fiction scenario could become a reality as the current trend continues in developing biologically inspired technologies. Technology evolution led to such fields as artificial muscles, artificial intelligence, and artificial vision as well as biomimetic capabilities in materials science, mechanics, electronics, computing science, information technology and many others. This paper will review the state of the art and challenges to biologically-inspired technologies and the role that EAP is expected to play as the technology evolves.

    2003-11-01

    Current medical robots have nothing in common with the anthropomorphic robots in science fiction classics. They are in fact, manipulators, working on a master-slave principle. Robots can be defined as "automatically controlled multitask manipulators, which are freely programmable in three or more spaces." The success of robots in surgery is based on their precision, lack of fatigue, and speed of action. This review describes the theory, advantages, disadvantages, and clinical utilization of mechanical and robotic arm systems to replace the second assistant and provide camera direction and stability during laparoscopic surgery. The Robotrac system (Aesculap, Burlingame, CA), the First Assistant (Leonard Medical Inc, Huntingdon Valley, PA), AESOP (Computer Motion, Goleta, CA), ZEUS (Computer Motion), and the da Vinci (Intuitive Surgical, Mountain View, CA) system are reviewed, as are simple mechanical-assist systems such as Omnitract (Minnesota Scientific, St. Paul, MN), Iron Intern (Automated Medical Products Corp., New York, NY), the Bookwalter retraction system (Codman , Somerville, NJ), the Surgassistant trade mark (Solos Endoscopy, Irvine, CA), the Trocar Sleeve Stabilizer (Richard Wolf Medical Instruments Corp., Rosemont, IL), and the Endoholder (Codman, Somerville, NJ).

    Full Text Available The increased application of the da Vinci robotic platform (Intuitive Surgical Inc. for microsurgery has led to the development of new adjunctive surgical instrumentation. In microsurgery, the robotic platform can provide high definition 12×-15× digital magnification, broader range of motion, fine instrument handling with decreased tremor, reduced surgeon fatigue, and improved surgical productivity. This paper presents novel adjunctive tools that provide enhanced optical magnification, micro-Doppler sensing of vessels down to a 1-mm size, vein mapping capabilities, hydro-dissection, micro-ablation technology (with minimal thermal spread-CO2 laser technology, and confocal microscopy to provide imaging at a cellular level. Microsurgical outcomes from the use of these tools in the management of patients with infertility and chronic groin and testicular pain are reviewed. All these instruments have been adapted for the robotic console and enhance the robot-assisted microsurgery experience. As the popularity of robot-assisted microsurgery grows, so will its breadth of instrumentation.

    Minimally invasive surgery for diseases in the pelvic region is gaining popularity due to advances in technology and increased benefit to the patient. As indications for such surgeries increase, the known boundaries for minimal access are being extended by a few teams. We report a patient who underwent robotic-assisted transabdominal repair of a high rectovaginal fistula which developed following a vaginal hysterectomy. Vaginography revealed a communication between the vaginal vault and the upper rectum. After evaluation of the colon and the vagina, the patient was planned for a robotic-assisted rectovaginal fistula repair. The three-arm daVinci(®) surgical robot was used. A total of five ports were used to complete the entire procedure, which included adhesiolysis, re-creation of the vaginal vault, repair of the fistula and omental interposition. This is the first robotic-assisted rectovaginal fistula repair reported to date. Besides the advantages of minimally invasive surgery for the patient, the surgeon benefits from the ease of suturing deep in the pelvis afforded by the articulated robotic arms.

    Advances in endoscopic techniques for abdominal procedures continue to reduce the invasiveness of surgery. Gaining access to the peritoneal cavity through small incisions prompted the first significant shift in general surgery. The complete elimination of external incisions through natural orifice access is potentially the next step in reducing patient trauma. While minimally invasive techniques offer significant patient advantages, the procedures are surgically challenging. Robotic surgical systems are being developed that address the visualization and manipulation limitations, but many of these systems remain constrained by the entry incisions. Alternatively, miniature in vivo robots are being developed that are completely inserted into the peritoneal cavity for laparoscopic and natural orifice procedures. These robots can provide vision and task assistance without the constraints of the entry incision, and can reduce the number of incisions required for laparoscopic procedures. In this study, a series of minimally invasive animal-model surgeries were performed using multiple miniature in vivo robots in cooperation with existing laparoscopy and endoscopy tools as well as the da Vinci Surgical System. These procedures demonstrate that miniature in vivo robots can address the visualization constraints of minimally invasive surgery by providing video feedback and task assistance from arbitrary orientations within the peritoneal cavity.

    2004-06-01

    With the initiation of laparoscopic techniques in general surgery, we have seen a significant expansion of minimally invasive techniques in the last 16 years. More recently, robotic-assisted laparoscopy has moved into the general surgeon's armamentarium to address some of the shortcomings of laparoscopic surgery. AESOP (Computer Motion, Goleta, CA) addressed the issue of visualization as a robotic camera holder. With the introduction of the ZEUS robotic surgical system (Computer Motion), the ability to remotely operate laparoscopic instruments became a reality. US Food and Drug Administration approval in July 2000 of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA) further defined the ability of a robotic-assist device to address limitations in laparoscopy. This includes a significant improvement in instrument dexterity, dampening of natural hand tremors, three-dimensional visualization, ergonomics, and camera stability. As experience with robotic technology increased and its applications to advanced laparoscopic procedures have become more understood, more procedures have been performed with robotic assistance. Numerous studies have shown equivalent or improved patient outcomes when robotic-assist devices are used. Initially, robotic-assisted laparoscopic cholecystectomy was deemed safe, and now robotics has been shown to be safe in foregut procedures, including Nissen fundoplication, Heller myotomy, gastric banding procedures, and Roux-en-Y gastric bypass. These techniques have been extrapolated to solid-organ procedures (splenectomy, adrenalectomy, and pancreatic surgery) as well as robotic-assisted laparoscopic colectomy. In this chapter, we review the evolution of robotic technology and its applications in general surgical procedures.

    Abandoned tailings ponds produce environmental and human health hazards due to the transfer of heavy metals through wind and water erosion or leaching. To reduce these hazards, a reclamation strategy has been developed on a tailings pond based on aided phytostabilization. In 2011 marble mud and pig slurry were applied to the surface of a tailings pond and in the spring of 2012 thirteen native vegetal species were introduced. The evolution of different soil properties and the bio-available fraction of the heavy metals Cd, Pb and Zn were monitored for two years (2012-2013). The results showed that the pH, aggregate stability, organic carbon, total nitrogen and cation exchange capacity increased after the application of the amendments and the growth of vegetation, whilst the bio-available fraction of the heavy metals drastically decreased (90-99%). Thus, the strategy followed proved to be positive for reducing the availability of heavy metals and improving soil quality and fertility. These results are promising in areas with extractive activity of carbonated materials, since the generated waste can be used for the reclamation of soils affected by heavy metals, transforming a residual material into a useful by-product.

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

    Barker, L. K.; Soloway, D.

    1987-01-01

    Kinematic resolved-rate control from one robot arm is extended to the coordinated control of multiple robot arms in the movement of an object. The structure supports the general movement of one axis system (moving reference frame) with respect to another axis system (control reference frame) by one or more robot arms. The grippers of the robot arms do not have to be parallel or at any pre-disposed positions on the object. For multiarm control, the operator chooses the same moving and control reference frames for each of the robot arms. Consequently, each arm then moves as though it were carrying out the commanded motions by itself.

    2009-01-01

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

    2012-01-01

    Advancements in the robotic surgical technology have revolutionized the standard of care for many surgical procedures. The purpose of this review is to evaluate the important considerations in developing a new robotics program at a given healthcare institution. Patients' interest in robotic-assisted surgery has and continues to grow because of improved outcomes and decreased periods of hospitalization. Resulting market forces have created a solid foundation for the implementation of robotic surgery into surgical practice. Given proper surgeon experience and an efficient system, robotic-assisted procedures have been cost comparable to open surgical alternatives. Surgeon training and experience is closely linked to the efficiency of a new robotics program. Formally trained robotic surgeons have better patient outcomes and shorter operative times. Training in robotics has shown no negative impact on patient outcomes or mentor learning curves. Individual economic factors of local healthcare settings must be evaluated when planning for a new robotics program. The high cost of the robotic surgical platform is best offset with a large surgical volume. A mature, experienced surgeon is integral to the success of a new robotics program.

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

    2009-01-01

    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. Future systems are expected to advance in two directions: improvements of remote manipulation robots and developments of image-guided robots. 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-user technical assessments. It is also notable that the potential of robots lies much further ahead than the accomplishments of the daVinci system. The integration of imaging with robotics holds a substantial promise, because this can accomplish tasks otherwise impossible. Image-guided robots have the potential to offer a paradigm shift.

    2017-01-01

    Full Text Available While robotic surgery has shown clear utility and advantages in the adult population, its role in pediatrics remains controversial. Pediatric-sized robotic instruments and equipment are not readily available yet, so certain modifications can be made in order to make robotic surgery successful in children. While the cost of robotic surgery remains high compared to open procedures, patients experience greater satisfaction and quality of life with robotic surgery. Robotic pyeloplasty is a standard of care in older children, and has even been performed in infants and re-do surgery. Other robotic procedures performed in children include heminephroureterectomy, ureteroureterostomy, ureteral reimplantation, urachal cyst excision, bladder diverticulectomy, and bladder reconstructive procedures such as augmentation, appendicovesicostomy, antegrade continence enema, bladder neck reconstruction and sling, as well as other procedures. Robotic surgery has also been used in oncologic cases such as partial nephrectomy and retroperitoneal lymph node dissection. Future improvements in technology with production of pediatric-sized robotic instruments, along with increases in robotic-trained pediatric urologists and surgeon experience along each's learning curve, will help to further advance the field of robotic surgery in pediatric urology.

    Robots have the potential to display a higher degree of lifetime morphological adaptation than natural organisms. By adopting a modular approach, robots with different capabilities, shapes, and sizes could, in theory, construct and reconfigure themselves as required. However, current modular robots have only been able to display a limited range of hardwired behaviors because they rely solely on distributed control. Here, we present robots whose bodies and control systems can merge to form entirely new robots that retain full sensorimotor control. Our control paradigm enables robots to exhibit properties that go beyond those of any existing machine or of any biological organism: the robots we present can merge to form larger bodies with a single centralized controller, split into separate bodies with independent controllers, and self-heal by removing or replacing malfunctioning body parts. This work takes us closer to robots that can autonomously change their size, form and function.Robots that can self-assemble into different morphologies are desired to perform tasks that require different physical capabilities. Mathews et al. design robots whose bodies and control systems can merge and split to form new robots that retain full sensorimotor control and act as a single entity.

    Several bio inspired swimming robots exist which seek to emulate the morphology of fish and the flapping motion of the tail and fins or other appendages and body of aquatic creatures. The locomotion of such robots and the aquatic animals that they seek to emulate is determined to a large degree by the changes in the shape of the body, which produce periodic changes in the momentum of the body and the creation and interaction of the vorticity field in the fluid with the body. We demonstrate an underactuated robot which swims due to the periodic changes in the angular momentum of the robot effected by the motion of an internal rotor. The robot is modular, unactuated tail like segments can be easily added to the robot. These segments modulate the interaction of the body with the fluid to produce a variety of passive shape changes that can allow the robot to swim in different modes.

    We have developed harvesting robots for tomato, petty-tomato, cucumber and grape in Japan. These robots mainly consist of manipulators, end-effectors, visual sensors and traveling devices. These mechanisms of the robot components were developed based on the physical properties of the work objects. The robots must work automatically by themselves in greenhouses or fields, since we are considering for one operator to tend several robots in the production system. The system is modeled after Japanese agriculture which is commonly seen to produce many kinds of crops in greenhouses and in many small fields intensively. Bioproduction in space is somewhat similar to the agricultural system in Japan, because few operators have to work in a small space. Employing robots for bioproduction in space is considered desirable in near future. The following is a description of the harvesting robots.

    2014-01-01

    This book tries to address the following questions: How should the uncertainty and incompleteness inherent to sensing the environment be represented and modelled in a way that will increase the autonomy of a robot? How should a robotic system perceive, infer, decide and act efficiently? These are two of the challenging questions robotics community and robotic researchers have been facing. The development of robotic domain by the 1980s spurred the convergence of automation to autonomy, and the field of robotics has consequently converged towards the field of artificial intelligence (AI). Since the end of that decade, the general public’s imagination has been stimulated by high expectations on autonomy, where AI and robotics try to solve difficult cognitive problems through algorithms developed from either philosophical and anthropological conjectures or incomplete notions of cognitive reasoning. Many of these developments do not unveil even a few of the processes through which biological organisms solve thes...

    Currently can find many models of industrial systems including robots. These models differ from each other not only by the accuracy representation parameters, but the representation range. For example, CAD models describe the geometry of the robot and some even designate a mass parameters as mass, center of gravity, moment of inertia, etc. These models are used in the design of robotic lines and sockets. Also systems for off-line programming use these models and many of them can be exported to CAD. It is important to note that models for off-line programming describe not only the geometry but contain the information necessary to create a program for the robot. Exports from CAD to off-line programming system requires additional information. These models are used for static determination of reachability points, and testing collision. It’s enough to generate a program for the robot, and even check the interaction of elements of the production line, or robotic cell. Mathematical models allow robots to study the properties of kinematic and dynamic of robot movement. In these models the geometry is not so important, so are used only selected parameters such as the length of the robot arm, the center of gravity, moment of inertia. These parameters are introduced into the equations of motion of the robot and motion parameters are determined.

    Full Text Available The development of research in robotics in a developing country is a challenging task. Factors such as low research funds, low trust from local companies and the government, and a small number of qualified researchers hinder the development of strong, local research groups. In this article, and as a case of study, we present our research group in robotics at the Advanced Mining Technology Center of the Universidad de Chile, and the way in which we have addressed these challenges. In 2008, we decided to focus our research efforts in mining, which is the main industry in Chile. We observed that this industry has needs in terms of safety, productivity, operational continuity, and environmental care. All these needs could be addressed with robotics and automation technology. In a first stage, we concentrate ourselves in building capabilities in field robotics, starting with the automation of a commercial vehicle. An important outcome of this project was the earn of the local mining industry confidence. Then, in a second stage started in 2012, we began working with the local mining industry in technological projects. In this article, we describe three of the technological projects that we have developed with industry support: (i an autonomous vehicle for mining environments without global positioning system coverage; (ii the inspection of the irrigation flow in heap leach piles using unmanned aerial vehicles and thermal cameras; and (iii an enhanced vision system for vehicle teleoperation in adverse climatic conditions.

    In January 2008, Duke University and the Japan Science and Technology Agency (JST) publicized their successful control of a brain-machine interface for a humanoid robot by a monkey brain across the Pacific Ocean. The activities of a few hundred neurons were recorded from a monkey's motor cortex in Miguel Nicolelis's lab at Duke University, and the kinematic features of monkey locomotion on a treadmill were decoded from neural firing rates in real time. The decoded information was sent to a humanoid robot, CB-i, in ATR Computational Neuroscience Laboratories located in Kyoto, Japan. This robot was developed by the JST International Collaborative Research Project (ICORP) as the "Computational Brain Project." CB-i's locomotion-like movement was video-recorded and projected on a screen in front of the monkey. Although the bidirectional communication used a conventional Internet connection, its delay was suppressed below one over several seconds, partly due to a video-streaming technique, and this encouraged the monkey's voluntary locomotion and influenced its brain activity. This commentary introduces the background and future directions of the brain-controlled robot.

  20. Soft Robotic Actuators

    Science.gov (United States)

    Godfrey, Juleon Taylor

    In this thesis a survey on soft robotic actuators is conducted. The actuators are classified into three main categories: Pneumatic Artificial Muscles (PAM), Electronic Electroactive Polymers (Electric EAP), and Ionic Electroactive Polymers (Ionic EAP). Soft robots can have many degrees and are more compliant than hard robots. This makes them suitable for applications that are difficult for hard robots. For each actuator background history, build materials, how they operate, and modeling are presented. Multiple actuators in each class are reviewed highlighting both their use and their mathematical formulation. In addition to the survey the McKibben actuator was chosen for fabrication and in-depth experimental analysis. Four McKibben actuators were fabricated using mesh sleeve, barbed hose fittings, and different elastic bladders. All were actuated using compressed air. Tensile tests were performed for each actuator to measure the tension force as air pressure increased from 20 to 100 psi in 10 psi increments. To account for material relaxation properties eleven trials for each actuator were run for 2-3 days. In conclusion, the smallest outer diameter elastic bladder was capable of producing the highest force due to the larger gap between the bladder and the sleeve.

  1. Emotions in robot psychology.

    Science.gov (United States)

    Nitsch, V; Popp, M

    2014-10-01

    In his famous thought experiments on synthetic vehicles, Valentino Braitenberg stipulated that simple stimulus-response reactions in an organism could evoke the appearance of complex behavior, which, to the unsuspecting human observer, may even appear to be driven by emotions such as fear, aggression, and even love (Braitenberg, Vehikel. Experimente mit künstlichen Wesen, Lit Verlag, 2004). In fact, humans appear to have a strong propensity to anthropomorphize, driven by our inherent desire for predictability that will quickly lead us to discern patterns, cause-and-effect relationships, and yes, emotions, in animated entities, be they natural or artificial. But might there be reasons, that we should intentionally "implement" emotions into artificial entities, such as robots? How would we proceed in creating robot emotions? And what, if any, are the ethical implications of creating "emotional" robots? The following article aims to shed some light on these questions with a multi-disciplinary review of recent empirical investigations into the various facets of emotions in robot psychology.

    1999-01-01

    This report describes a three-month research program undertook jointly by the Robotics Institute at Carnegie Mellon University and Ames Research Center as part of the Ames' Joint Research Initiative (JRI.) The work was conducted at the Ames Research Center by Mr. Liam Pedersen, a graduate student in the CMU Ph.D. program in Robotics under the supervision Dr. Ted Roush at the Space Science Division of the Ames Research Center from May 15 1999 to August 15, 1999. Dr. Martial Hebert is Mr. Pedersen's research adviser at CMU and is Principal Investigator of this Grant. The goal of this project is to investigate and implement methods suitable for a robotic rover to autonomously identify rocks and minerals in its vicinity, and to statistically characterize the local geological environment. Although primary sensors for these tasks are a reflection spectrometer and color camera, the goal is to create a framework under which data from multiple sensors, and multiple readings on the same object, can be combined in a principled manner. Furthermore, it is envisioned that knowledge of the local area, either a priori or gathered by the robot, will be used to improve classification accuracy. The key results obtained during this project are: The continuation of the development of a rock classifier; development of theoretical statistical methods; development of methods for evaluating and selecting sensors; and experimentation with data mining techniques on the Ames spectral library. The results of this work are being applied at CMU, in particular in the context of the Winter 99 Antarctica expedition in which the classification techniques will be used on the Nomad robot. Conversely, the software developed based on those techniques will continue to be made available to NASA Ames and the data collected from the Nomad experiments will also be made available.

    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.

    Full Text Available Resumen: Los actuadores de rigidez variable son dispositivos que permiten cambiar la posición y rigidez articular de un robot en forma simultánea. En los últimos años se han diseñado y desarrollado muchos dispositivos de este tipo, con la esperanza de favorecer la seguridad en la interacción humano-robot y mejorar el rendimiento dinámico de los robots. En este artículo se presenta el desarrollo de un controlador para un actuador de rigidez variable de configuración serie. La estrategia de control se basa en la linealización por realimentación y el ajuste de dos controladores lineales. Esta estrategia permite el seguimiento de referencias de posición y rigidez articular de forma simultánea y desacoplada. Además, se realizan simulaciones en las que se incorpora este dispositivo dentro del robot asistencial ASIBOT, a fin de evaluar el desempeño del controlador, los cambios en la dinámica del robot y las posibles ventajas que tendrá la inclusión del mismo a nivel de seguridad en la interacción física humano-robot. Abstract: The variable stiffness actuators are devices that change the position and stiffness of a robot simultaneously. In recent years have been designed and developed many devices of this type, hoping to ensure safety in human-robot interaction and improve the dynamic performance of robots. In this article, we present the control of a variable stiffness actuator with serial configuration. The control strategy is based on feedback linearization and adjustment of two linear controllers. This allows the control, independently, of the stiffness and the equilibrium position of the joint. Finally, the behavior of this device within the assistive robot ASIBOT, is simulated in order to assess: the controller performance, changes in the dynamics of the robot and possible advantages of a level of safety during physical interaction human-robot.

    Friendship is used here as a conceptual vehicle for framing questions about the distinctiveness of human cognition in relation to natural systems such as other animal species and to artificial systems such as robots. By exploring this very common form of a human interpersonal relationship...... of friendship as a triadic relation analogous to the sign relation is suggested. Based on this the author asks how one may conceive of robot-robot and robot-human friendships; and how an interdisciplinary perspective upon that relation can contribute to analyse levels of embodied cognition in natural...

    Asimov's three laws of robotics, which were shaped in the literary work of Isaac Asimov (1920-1992) and others, define a crucial code of behavior that fictional autonomous robots must obey as a condition for their integration into human society. While, general implementation of these laws in robots is widely considered impractical, limited-scope versions have been demonstrated and have proven useful in spurring scientific debate on aspects of safety and autonomy in robots and intelligent systems. In this work, we use Asimov's laws to examine these notions in molecular robots fabricated from DNA origami. We successfully programmed these robots to obey, by means of interactions between individual robots in a large population, an appropriately scoped variant of Asimov's laws, and even emulate the key scenario from Asimov's story "Runaround," in which a fictional robot gets into trouble despite adhering to the laws. Our findings show that abstract, complex notions can be encoded and implemented at the molecular scale, when we understand robots on this scale on the basis of their interactions.

  13. Robotic Surgery in Gynecologic Oncology

    2011-01-01

    Full Text Available Robotic surgery for the management of gynecologic cancers allows for minimally invasive surgical removal of cancer-bearing organs and tissues using sophisticated surgeon-manipulated, robotic surgical instrumentation. Early on, gynecologic oncologists recognized that minimally invasive surgery was associated with less surgical morbidity and that it shortened postoperative recovery. Now, robotic surgery represents an effective alternative to conventional laparotomy. Since its widespread adoption, minimally invasive surgery has become an option not only for the morbidly obese but for women with gynecologic malignancy where conventional laparotomy has been associated with significant morbidity. As such, this paper considers indications for robotic surgery, reflects on outcomes from initial robotic surgical outcomes data, reviews cost efficacy and implications in surgical training, and discusses new roles for robotic surgery in gynecologic cancer management.

  3. New Approaches to Robotics

    Brooks, Rodney A.

    1991-09-01

    In order to build autonomous robots that can carry out useful work in unstructured environments new approaches have been developed to building intelligent systems. The relationship to traditional academic robotics and traditional artificial intelligence is examined. In the new approaches a tight coupling of sensing to action produces architectures for intelligence that are networks of simple computational elements which are quite broad, but not very deep. Recent work within this approach has demonstrated the use of representations, expectations, plans, goals, and learning, but without resorting to the traditional uses of central, abstractly manipulable or symbolic representations. Perception within these systems is often an active process, and the dynamics of the interactions with the world are extremely important. The question of how to evaluate and compare the new to traditional work still provokes vigorous discussion.

    Liquid droplets are very simple objects present in our everyday life. They are extremely important for many natural phenomena as well as for a broad variety of industrial processes. The conventional research areas in which the droplets are studied include physical chemistry, fluid mechanics, chemical engineering, materials science, and micro- and nanotechnology. Typical studies include phenomena such as condensation and droplet formation, evaporation of droplets, or wetting of surfaces. The present article reviews the recent literature that employs droplets as animated soft matter. It is argued that droplets can be considered as liquid robots possessing some characteristics of living systems, and such properties can be applied to unconventional computing through maze solving or operation in logic gates. In particular, the lifelike properties and behavior of liquid robots, namely (i) movement, (ii) self-division, and (iii) group dynamics, will be discussed.

    We argue that all embodied organisms, whether robots or animals, face the same challenge: of adapting to bodies, brains and environments that undergo constant and inevitable change. After highlighting the evidence for the universal role of a class of molecular factors called neurotrophic factors in the response of animals to this challenge, we suggest that implementing models of neurotrophic interactions on robots may confer on them the adaptability and robustness exhibited by animals. We briefly review a mathematical model of neurotrophic interactions and then discuss its application in a robotic context. Finally, we examine the potential, or otherwise, of our approach to developmental robotics.

    Onen, Mehmet Resid; Naderi, Sait

    2014-01-01

    Surgical robotic systems have been available for almost twenty years. The first surgical robotic systems were designed as supportive systems for laparoscopic approaches in general surgery (the first procedure was a cholecystectomy in 1987). The da Vinci Robotic System is the most common system used for robotic surgery today. This system is widely used in urology, gynecology and other surgical disciplines, and recently there have been initial reports of its use in spine surgery, for transoral access and anterior approaches for lumbar inter-body fusion interventions. SpineAssist, which is widely used in spine surgery, and Renaissance Robotic Systems, which are considered the next generation of robotic systems, are now FDA approved. These robotic systems are designed for use as guidance systems in spine instrumentation, cement augmentations and biopsies. The aim is to increase surgical accuracy while reducing the intra-operative exposure to harmful radiation to the patient and operating team personnel during the intervention. We offer a review of the published literature related to the use of robotic systems in spine surgery and provide information on using robotic systems.

  18. Robotic approaches to prolapse surgery.

    2012-07-01

    Pelvic reconstructive surgeons in the fields of urology, gynecology and urogynecology have continually adapted new techniques in pelvic organ prolapse (POP) repair in order to improve both anatomic and subjective outcomes. In the last 5 years, robotic surgery has gained a strong foothold in urologic oncology, gynecologic oncology, cardiothoracic surgery and now in female pelvic medicine. Robotic surgery has made its way into the armamentarium of POP treatment and has allowed pelvic surgeons to adapt the 'gold standard' technique of abdominal sacrocolpopexy to a minimally invasive approach with improved intraoperative morbidity and decreased convalescence. This review article aims to discuss the techniques of robotic prolapse repair as well as morbidity, cost and clinical outcomes. The adaptation of minimally invasive approaches to the treatment of POP initially began with laparoscopy, something only those surgeons with extensive and advanced laparoscopic skills are able to accomplish. Access to robotic technology makes conversion from open or laparoscopic to robotic surgery much more feasible for most pelvic floor surgeons. There are currently no published randomized, controlled trials comparing robotic with open or laparoscopic sacrocolpopexy, however, there are several publications reporting both retrospective and prospective series of women undergoing robotic-assisted sacrocolpopexy. Robotic-assisted pelvic floor surgery has become an important component of the pelvic surgeon's armamentarium in the treatment of symptomatic POP. Those pelvic surgeons without significant expertise in laparoscopy required for sacral dissection and intracorporeal suturing can readily learn the necessary techniques required for robotic surgery.

    Carelli, Laura; Gaggioli, Andrea; Pioggia, Giovanni; De Rossi, Federico; Riva, Giuseppe

    2009-01-01

    Recently, several robotic solutions for the elderly have been proposed. However, to date, the diffusion of these devices has been limited: available robots are too cumbersome, awkward, and expensive to become widely adopted. Another key issue which reduces the appeal of assistive robots is the lack of socio-emotional interaction: affective interchanges represent key requirements to create sustainable relationships between elderly and robots. In this paper, we propose a new approach to enhance the acceptability of robotic systems, based on the introduction of affective dimensions in human-robot interaction. This strategy is aimed at designing a new generation of relational and cognitive robots fusing information from embodied unobtrusive sensory interfaces. The final objective is to develop embodied interfaces, which are able to learn and adapt their affective responses to the user's behavior. User and robot will engage in natural interactions, involving verbal and non-verbal communication, improving empathic exchange of moods and feelings. Relevant independent living and quality of life related issues will be addressed: on-going monitoring of health parameters, assistance in everyday's activities, social support and cognitive/physical exercises. We expect that the proposed strategy will enhance the user's acceptance and adoption of the assistive robotic system.

The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations.

    2012-01-01

    Full Text Available This paper proposes a general method for robots to learn motions and corresponding semantic knowledge simultaneously. A modified ISOMAP algorithm is used to convert the sampled 6D vectors of joint angles into 2D trajectories, and the required movements for writing numbers are learned from this modified ISOMAP-based model. Using this algorithm, the knowledge models are established. Learned motion and knowledge models are stored in a 2D latent space. Gaussian Process (GP method is used to model and represent these models. Practical experiments are carried out on a humanoid robot, named ISAC, to learn the semantic representations of numbers and the movements of writing numbers through imitation and to verify the effectiveness of this framework. This framework is applied into training a humanoid robot, named ISAC. At the learning stage, ISAC not only learns the dynamics of the movement required to write the numbers, but also learns the semantic meaning of the numbers which are related to the writing movements from the same data set. Given speech commands, ISAC recognizes the words and generated corresponding motion trajectories to write the numbers. This imitation learning method is implemented on a cognitive architecture to provide robust cognitive information processing.

    Renal ptosis is defined as the renal descent when there is a change from supine to orthostatic position, usually with a change of two vertebral bodies or more than five cm apart. Although rare, it is one of the causes of chronic flank pain or of upper abdomen. The typical patient of renal ptosis is young, female, thin, with complaint of pain when in an upright position (1, 2). Demonstrate a robot-assisted nephropexy technique in a young woman diagnosed with symptomatic renal ptosis on the right kidney, confirmed by imaging tests. A 29-year-old female patient with a history of chronic right-sided pain and palpable renal mobility on physical examination. The diagnosis of renal ptosis was confirmed by ultrasound imaging, excretory urography (Figure -1), and renal scintigraphy with 99mTc-DTPA (Figure-2). She was submitted to a robotic-assisted right nephropexy with a polypropylene mesh fixing the right kidney to the ipsilateral psoas muscle fascia. We reported a 96-minute surgical time. The patient was discharged in the first postoperative day. At the one-month follow-up, there was an important improvement of the symptoms, with normality renal function and imaging tests describing adequate renal positioning. Robotic-assisted nephropexy is feasible and can be an excellent minimally invasive alternative technique for the proposed surgery. We reported a shorter hospital stay and a faster postoperative recovery compared with the opened procedure. Copyright® by the International Brazilian Journal of Urology.

    Environmental restoration and waste management (ER and WM) challenges in the United States Department of Energy (DOE), and around the world, involve radiation or other hazards which will necessitate the use of remote operations to protect human workers from dangerous exposures. Remote operations carry the implication of greater costs since remote work systems are inherently less productive than contact human work due to the inefficiencies/complexities of teleoperation. To reduce costs and improve quality, much attention has been focused on methods to improve the productivity of combined human operator/remote equipment systems; the achievements to date are modest at best. The most promising avenue in the near term is to supplement conventional remote work systems with robotic planning and control techniques borrowed from manufacturing and other domains where robotic automation has been used. Practical combinations of teleoperation and robotic control will yield telerobotic work systems that outperform currently available remote equipment. It is believed that practical telerobotic systems may increase remote work efficiencies significantly. Increases of 30% to 50% have been conservatively estimated for typical remote operations. It is important to recognize that the basic hardware and software features of most modern remote manipulation systems can readily accommodate the functionality required for telerobotics. Further, several of the additional system ingredients necessary to implement telerobotic control--machine vision, 3D object and workspace modeling, automatic tool path generation and collision-free trajectory planning--are existent.

    A walking robot was designed, analyzed, and tested as an intelligent, mobile, and a terrain adaptive system. The robot's design was an application of existing technologies. The design of the six legs modified and combines well understood mechanisms and was optimized for performance, flexibility, and simplicity. The body design incorporated two tripods for walking stability and ease of turning. The electrical hardware design used modularity and distributed processing to drive the motors. The software design used feedback to coordinate the system and simple keystrokes to give commands. The walking machine can be easily adapted to hostile environments such as high radiation zones and alien terrain. The primary goal of the leg design was to create a leg capable of supporting a robot's body and electrical hardware while walking or performing desired tasks, namely those required for planetary exploration. The leg designers intent was to study the maximum amount of flexibility and maneuverability achievable by the simplest and lightest leg design. The main constraints for the leg design were leg kinematics, ease of assembly, degrees of freedom, number of motors, overall size, and weight.
