    Full Text Available Compuestos presentes en los vegetales con propiedades funcionales o tecnológicas, han cobrado gran importancia en los mercados de alimentos, farmacéuticos y cosméticos. Se buscan métodos eficientes, económicos y favorables al ambiente para la extracción de estas sustancias. Se ha realizado un estudio bibliográfico de las publicaciones recientes sobre diferentes métodos de extracción y su comparación a las extracciones asistidas por ultrasonido (EAU con el fin de evaluar su eficacia y viabilidad industrial. Se ha encontrado que la EAU es más eficiente que los métodos de extracción tradicionales, y más económica y sencilla que los métodos de extracción no tradicionales como la extracción asistida por microondas, por lo cual se comprueba su viabilidad industrial.

    RESUMEN

    El Síndrome de Balint, descrito en 1909, es un trastorno producido por las lesiones bilaterales de ambos lóbulos parieto-occipitales, que afecta a la conexión entre las regiones corticales de la visión y las áreas motrices prerrolándicas y caracterizado por la presencia de ataxia visual, incapacidad para ver y coger objetos e inatención visual. Amén de los métodos tradicionales de evaluación y tratamiento desde Terapia Ocupacional de los trastornos motrices producidos por el Síndrome, proponemos aquí una nueva vía de realización de ambas utilizando las nuevas tecnologías, haciendo realidad la Terapia Ocupacional Asistida por Ordenador.
    PALABRAS CLAVE: Terapia Ocupacional, ataxia óptica, atención visual, movimientos sacádicos.

     

    ABSTRACT

    Balint Syndrome, which was reported in 1909, is an affection produced by bilateral parieto-occipital lesions affecting the connections between the visual cortical regions and the prerolandic motor areas and caracterized by visual ataxia, failure to grasp or touch objects, and visual inatention. Beyond traditional evaluation and treatment methods applied from Occupational Therapy to the motor diseases produced by syndrome, we propose a new way to do them using new technologies, doing reality Computer Assisted Occupational Therapy.

    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.

  7. Ventajas de la cicatrización cutánea asistida por láser (LASH

    Directory of Open Access Journals (Sweden)

    S. Mordon

    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.

    Full Text Available El control efectivo contra enfermedad Infecciosa de la bolsa se basa en las medidas de bioseguridad y en la aplicación de un programa de vacunación efectivo, donde la selección adecuada del momento óptimo de aplicación de la primera dosis de vacuna está determinado por los niveles de anticuerpos maternos (vacunación asistida.En este trabajo se estudió la declinación de los anticuerpos maternos en el tiempo en 40 pollitos de la raza Leghorn desde un día hasta los 31 días por sueroneutralización y se elaboró una ecuación para predecir el momento adecuado de vacunación. También se estudiaron pollitos de un día de edad pertenecientes a dos granjas diferentes, en las cuales se aplicó la primera dosis de vacuna cuando los títulos de anticuerpos maternos oscilaba entre 1:80 y 1:100.La vacunación consistió en dos dosis con un intervalo de diez días. Antes de la aplicación de cada vacuna, así como a los 21 días postvacunación con la última dosis se determinó la presencia de anticuerpos contra la enfermedad infecciosas de la bolsa por sueroneutralización. Todos los pollos fueron confrontados a este mismo tiempo con un aislamiento de campo.Se obtuvo en todos los casos una respuesta adecuada a la vacunación, con elevados títulos neutralizantes a los 21 días de edad y en ninguno de los pollos confrontados se observó ni sintomatología clínica, ni alteraciones histopatológicas en la bolsa de Fabricio, lo que indica que la vacunación fue aplicada en el momento óptimo.

Presentan riesgos asociados a la transferencia múltiple de embriones; riesgos para la salud de la paciente por el tratamiento, y riesgos para la descendencia. Riesgos asociados a las futuras relaciones paterno/filiares y fraternales. Los principales problemas técnicos -el tratamiento para la estimulación ovárica, la manipulación de gametos y el cultivo de los embriones, su conservación en frío, el número de embriones a transferir, y su correcta implantación en el útero-, siguen sin encontrar la solución definitiva, y no desciende la mortalidad embrionaria y neonatal. Para algunos de estos problemas se ha tomado como solución la donación de óvulos y espermios, o el encargo de la gestación a otra mujer. De esta forma las TRA se han sacado del ámbito de la pareja estable estéril y se ha abierto a mujeres solas, a mujeres de edad avanzada, a parejas del mismo sexo, etc. Aportamos aquí los datos actuales acerca del estado de las TRA, y lo programado para el futuro. Los datos muestran la exigencia de re-examinarlas, para lo que es imprescindible dar a conocer los resultados, no sólo a quienes acuden para su utilización, sino a la sociedad.

    Full Text Available Se desarrolló un método multirresiduo para la determinación de diferentes tipos de plaguicidas en suelos. El proceso de extracción consistió en una doble extracción con acetato de etilo ymetanol asistido con ultrasonido. Los plaguicidas fueron determinados por cromatografía de gases con detección por microcaptura de electrones (-ECD y nitrógeno fósforo (NPD. Se evaluaron los porcentajes de recuperación de la metodología, en un rango de concentraciones entre 0,09 mg/kg y 14,60 mg/kg, y se determinó que la mayoría se encuentran entre 79% y 105%, a excepción de metamidofos, monocrotofos y oxadixyl, cuyos porcentajes de recuperación se encontraron entre 43% y 64%. Por otra parte, los límites de detección del método se encontraron en un rango de 0,02 mg/kg y 1,59mg/kg, y los límites de cuantificación entre 0,07 mg/kg y 5,25mg/kg. En el estudio de linealidad y precisión se encontraron resultados adecuados en el rango de concentración evaluado. Finalmente, se empleó esta metodología para evaluar los porcentajes de recuperación en 5 suelos de diferentes características fisicoquímicas.

    Full Text Available Las Técnicas de Reproducción Asistida (TRA -Estimulación ovárica, Inseminación Intrauterina (IUI, o Fecundación in vitro (FIV/Inyección Intra-Citoplasmática de un Espermio (ICSI- han hecho posible el nacimiento de cientos de miles niños, muchos de los cuales están entrando en la edad adulta. Al inicio de los años 90 comienza una alerta pediátrica por los defectos y anomalías que presentaban estos niños, en proporción más alta que los nacidos de forma natural. Su peor salud se hace incuestionable a partir del 2002. Las técnicas son en sí sumamente agresivas; las pérdidas de embriones antes de la implantación, los abortos espontáneos y la mortalidad perinatal es muy elevada. No se ha hecho la imprescindible experimentación previa con animales: y las pruebas con animales fértiles han mostrado que las crías generadas in vitro presentan alteraciones graves. Sin embargo, los daños se atribuían, casi exclusivamente y de forma gratuita, a la edad avanzada de las mujeres usuarias de las técnicas, y a la esterilidad por las alteraciones genéticas de los espermatozoides, en aumento por los contaminantes del ambiente. Se ha llevado a cabo una extensa experimentación humana directa, sin cumplir los requisitos mínimos de la experimentación humana, e ignorando qué papel desempeñan las técnicas en sí mismas y cómo se causan los defectos que padecen una parte de los así generados, ni exactamente que podrán transmitir a las siguientes generaciones. No estamos ante una cuestión de riesgo/ beneficio sino ante un problema de salud. Las TRA no son intervenciones encaminadas a solucionar un problema físico o fisiológico vital. La proporcionalidad entre la satisfacción del deseo de maternidad/paternidad y los riesgos para la salud del hijo debe ser un criterio primario, aunque no el único.

    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.

    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.

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.

    Full Text Available Heterostructures of Si1-xGex alloys on Si (100 have been achieved using two different excimer laser techniques. The first one, the Laser Induced Chemical Vapour Deposition (LCVD, was used in order to deposit germanium on Si (100 substrates via photolysis of GeH4 as precursor gas. The resulting films show a very homogeneous and amorphous structure as determined by HREM, XRD and Raman analysis. These deposited amorphous germanium films and a part of their underlaying Si (100 substrate were melted using the second technique, the Pulsed Laser Induced Epitaxy (PLIE, inducing an epitactic recrystallization of a Si-Ge alloy. The analysis of the obtained alloys by HREM, XRD, and XPS, reveals a strong dependence of the crystal quality and of the germanium concentration profile from the number of pulses.

    El creciente interés que suscita la búsqueda de nuevas técnicas para la obtención de materiales semiconductores, compatibles con la tecnología del silicio, ha llevado a desarrollar un sistema de depósito y postprocesado en alto vacío (HV de Si-Ge mediante técnicas asistidas por láser excímero. Se han obtenido películas amorfas de germanio mediante el depósito químico en fase vapor inducido por láser (LCVD, que posteriormente han sido recristalizadas con uso de la inducción de epitaxia por medio de láser pulsado (PLIE. Las películas depositadas sobre substratos de silicio fueron caracterizadas mediante XRD, HREM y Raman, revelándose que son amorfas con un alto grado de homogeneidad. Se ha estudiado la morfología y la estequiometría de las muestras por medio de XRD, HREM y XPS tras el tratamiento para inducir la cristalinidad de la aleación sobre el substrato de silicio, observándose la dependencia del grado de heteroepitaxia y variación de la composición en la aleación, con el número y la energía de los pulsos del láser.

    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

    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.

    一篇介绍机器人的文章写得如此耐读,如此清新! 首先.我们弄清了robot一词的来历: It was used first in 1920 in a play by Czcchoslovak writer Karel Capek.The wordrobot comes from the Czech word for slave. 上句提供了一个时间:1920。文章接着便抓住这个时间做文章: 且The word robot.and robots themselves are less than 100 years old.But humanshave been dreaming of real and imaginary copies of themselves for thousands of years. 文章就这样写出了波澜,1920年和 thousands of years自然而然构成了强烈对比。1954年和1960s是两个谈及机器人时不得不一提的时间: In 1954,the world’s first robot was produced in the United States. During the 1960s,the first industrial robots appeared beside human workers infactories.下面这句让我们体味到 the Czech word for slave中的 slave不仅言之有理,而且影视和小说里的机器人“造反”,进而 killed the humans who made them的情节也“事出有因”: What do today’s robots do?Robots do work.Work that human consideruninteresting or dangerous.…do many jobs that people consider tiring. 本文将机器人的“功过”放在一起写,笔

    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 Actualmente son diversos los métodos utilizados para la medición de una inclinación de un cuerpo respecto a una referencia o un marco fijo, pero el problema radica en los costos que estos acarrean, siendo este un factor limitante para el desarrollo científico cuando se dispone de bajos recursos económicos. En Este punto es en donde se hace relevante la investigación y el desarrollo en materia de tecnología llevado a cavo, en este articulo, ya que la finalidad del presente proyecto, consiste en proporcionarle estabilidad a un robot autónomo de un solo eje, para lo cual se hace necesario, la implementación de un sistema de control de inclinación. El sistema de detección de inclinación desarrollado, está basado en el ultrasonido como herramienta principal de medición de distancia entre dos puntos equidistantes del eje central de la plataforma robótica, la cual es inestable por naturaleza. Mediante este nuevo método, se ha logrado establecer magnitudes de inclinación del orden de fracciones de grados, ya que los transductores piezoeléctricos en conjunto con la electrónica implementada, brinda gran precisión en las medidas realizadas.

    Full Text Available Existe una línea divisoria evidente entre las actuaciones encaminadas a curar la esterilidad interviniendo en sus causas, y las técnicas encaminadas a generar embriones y transferirlos al útero. Esa línea divisoria, entre curar/paliar y generar el hijo por la tecnología de la reproducción asistida, la traza primariamente la ciencia. La alarma creciente de neonatólogos y pediatras ante el riesgo mayor de padecer enfermedades y malformaciones de los niños generados in vitro respecto a los engendrados, conlleva el deber de un examen riguroso de las consecuencias de la aplicación de esta tecnología. Dos tipos de carencias de comunicación intercelular y molecular causan los diversos defectos. En primer lugar, se obvia la necesidad del reconocimiento específi co de los gametos en su estado de maduración adecuado y en el medio na tural de la fecundación, por lo que ésta se fuerza y se llega a realizar careciendo de capacidad fecundante uno o ambos gametos. En segundo lugar, tanto al desarrollo inicial del embrión como al útero materno, se les resta la comunicación materno-fi lial que permite y facilita la anidación.

    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.

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.

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 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.

    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 los últimos años se ha producido un descenso progresivo de la fertilidad, originado, fundamentalmente por el envejecimiento de los óvulos en la mujer y en el hombre por alteraciones del material genético de los espermatozoides causados por factores ambientales acumulativos con el paso del tiempo. Los tratamientos de infertilidad, así como las técnicas de reproducción humana asistida -fecundación in vitro o inseminación- consisten, o están precedidas, por un tratamiento de estimulación ovárica que persigue la obtención de un número elevado de óvulos maduros en un ciclo. Esta estimulación no resuelve la cuestión esencial del cambio del patrón de modificación química, impronta parental, que ocurre en el proceso epigenético de la ovogénesis. Los óvulos inducidos a madurar y/o forzados a su fecundación, no aportan el genoma en la situación de estreno que en cada generación pasa de progenitores a hijos. Esos cambios afectan a la regulación de la expresión de un grupo de genes (conocidos como genes con impronta durante el desarrollo embrionario del hijo; estas alteraciones pueden aportarle una predisposición a enfermedades poco frecuentes que tienen su origen precisamente en el descontrol de tales genes. Algunos factores que causan infertilidad pueden tener su origen en etapas tempranas de su desarrollo. Por ello, la infertilidad es ya un tema intergeneracional que hace necesario dar a conocer y alertar sobre los factores importantes, y las formas de vida, que dan origen a un problema emergente.

    Full Text Available Che cosa e' un robot? A che cosa serve un robot? Un robot e' qualcosa di fisico, costruito da noi, che somiglia a un organismo vivente e si comporta come un organismo vivente. Gli organismi viventi comprendono gli animali e le piante, ma i robot riproducono gli animali piuttosto che le piante, anche se ci sono tentativi di costruire robotpiante. Comportarsi come un animale significa avere degli organi sensoriali con cui ricevere informazioni dall'ambiente e degli organi motori che permettono di spostarsi nell'ambiente o di muovere una qualche parte del proprio corpo, ad esempio la testa o un braccio, in maniera non programmata, ma autonoma, cioe' rispondendo agli stimoli che arrivano momento per momento ai sensori del robot. Questo risponde alla domanda "Che cosa e' un robot?".

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

    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.

    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.

    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.

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

  16. Soft robotics: a bioinspired evolution in robotics.

    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.

    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 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

    Begody, Ericka

    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

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

    Full Text Available 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.

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

    This book is organized into nine chapters. Chapter 1 presents general robot characteristics concerning the classification of robot systems, the general specification of robot mechanisms and the specification of manipulation robots. Chapter 2 is devoted to manipulation robot kinematics. It treats the kinematic structure of manipulation robots, the types of kinematic configurations, the kinematic model of manipulation robots, based on the Denavit-Hartenberg (homogeneous) coordinates. The inverse problem of kinematics is formulated and the basic principles of robot trajectory synthesis are given. Chapter 3 contains the fundamentals of studying robot dynamics. It presents the automated construction of the dynamic equations of motion, the modelling of actuator dynamics and the effect of fundamental vibration on the robot dynamics. The class of tasks involving constrained gripper motion is also presented. The problems of manipulation robot control are discussed in Chapter 4. Chapter 5 is devoted to the microcomputer implementation of control algorithms. It presents the basic elements of today's robot control systems as well as software modules among which communication-command module, kinematic module and dynamic (servosystem) module deserve to be especially mentioned. Manipulation robot programming is treated in Chapter 6. Chapter 7 deals with the sensors used in robotics: position sensors (potentiometers, encoders, resolvers), environment sensors (force sensors, tactile sensors, proximity sensors) and vision sensors (scene illumination, special vision sensors, lasers). The elements of industrial robot design and application are discussed in Chapter 8. In Chapter 9 the authors try to unify in a systematic way major problems (and possible solutions) encountered with factory automation by integrating one or more robots and several machine tools into work cell, flexible manufacturing line and assembly systems.

    2011-10-01

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

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

    The surgical robot has the potential to enable a laparoscopic approach to procedures that are presently performed by laparotomy due to the technical difficulties intrinsic to laparoscopy. The use of the current robot prototypes are not cost-effective for gynecologic procedures that are already performed by laparoscopy. The rapid evolution of robotics will likely allow for more widespread application in all surgical specialties in the future.

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

    Bhamjee, Sajida; Griffiths, Frances; Palmer, Julie

    Technology is advancing rapidly; especially in the field of robotics. The purpose of this study was to examine children's perception and interpretation of robots and robot behaviour. The study was divided into two phases: phase one involved 144 children (aged 7-8) from two primary schools drawing a picture of a robot and then writing a story about the robot that they had drawn. In phase two, in small groups, 90 children observed four e-puck robots interacting within an arena. The children were asked three questions during the observation: 'What do you think the robots are doing?', 'Why are they doing these things?' and 'What is going on inside the robot?' The results indicated that children can hold multiple understandings of robots simultaneously. Children tend to attribute animate characteristics to robots. Although this may be explained by their stage of development, it may also influence how their generation integrates robots into society.

    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.

  11. [Robots and intellectual property].

    Science.gov (United States)

    Larrieu, Jacques

    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.

  13. Human-Robot Interaction

    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

  15. [Robotic surgery in gynecology].

    2012-06-24

    Minimally invasive surgery has revolutionized gynecological interventions over the past 30 years. The introduction of the da Vinci robotic surgery in 2005 has resulted in large changes in surgical management. The robotic platform allows less experienced laparoscopic surgeons to perform more complex procedures. It can be utilized mainly in general gynecology and reproductive gynecology. The robot is being increasingly used for procedures such as hysterectomy, myomectomy, adnexal surgery, and tubal anastomosis. In urogynecology, the robot is being utilized for sacrocolopexy as well. In the field of gynecologic oncology, the robot is being increasingly used for hysterectomy and lymphadenectomy in oncologic diseases. Despite the rapid and widespread adaption of robotic surgery in gynecology, there are no randomized trials comparing its efficacy and safety to other traditional surgical approaches. This article presents the development, technical aspects and indications of robotic surgery in gynecology, based on the previously published reviews. Robotic surgery can be highly advantageous with the right amount of training, along with appropriate patient selection. Patients will have less blood loss, less post-operative pain, faster recovery, and fewer complications compared to open surgery and laparoscopy. However, until larger randomized control trials are completed which report long-term outcomes, robotic surgery cannot be stated to have priority over other surgical methods.

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

    Frick, A C; Falcone, T

    2009-06-01

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

    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.

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

    1998-01-01

    Quantum robots and their interactions with environments of quantum systems are described and their study justified. A quantum robot is a mobile quantum system that includes a quantum computer and needed ancillary systems on board. Quantum robots carry out tasks whose goals include specified changes in the state of the environment or carrying out measurements on the environment. Each task is a sequence of alternating computation and action phases. Computation phase activities include determination of the action to be carried out in the next phase and possible recording of information on neighborhood environmental system states. Action phase activities include motion of the quantum robot and changes of neighborhood environment system states. Models of quantum robots and their interactions with environments are described using discrete space and time. To each task is associated a unitary step operator T that gives the single time step dynamics. T = T_{a}+T_{c} is a sum of action phase and computation phase step ...

    The widespread robotic surgery in the world highlighted the relevance of the training programs for young urologists and residents. In the last years, urologic societies and some independent robotic surgeons strongly worked to standardize some general and specific training modules. Theoretical and practical sections of robotic training programs have been recently specified. The role of simulators, dry and wet laboratories, bedside assistance, and modular (step-by-step) training at console represent the most relevant elements of robotic surgeon training. Ideally, these didactic tools should be available in modern training centers. The development of structured robotic training programs should be considered as one of the priorities that the urologic community must take into account in the near future.

    Space robots will be an indispensable element of future space missions such as the construction of large-scale structures in space, maintenance of satellites in orbit, lunar and planetary exploration, and experiments on the international space station. These mission objectives require various types of space robots. It is considered that there are five key technologies in common for the development of these robots: those for achieving small size and light weight, high-accuracy measurement, high-level control, remote control, and standardization. Some of these technologies have been demonstrated in orbit by the experimental operations of the Engineering Test Satellite VII (ETS-VII) developed by the National Space Development Agency of Japan (NASDA). Toshiba continues to study these key technologies. (author)

    In this paper we summarize a survey conducted by NASA to determine the state-of-the-art in space robotics and to predict future robotic capabilities under either nominal and intensive development effort. The space robotics assessment study examined both in-space operations including assembly, inspection, and maintenance and planetary surface operations like mobility and exploration. Applications of robotic autonomy and human-robot cooperation were considered. The study group devised a decomposition of robotic capabilities and then suggested metrics to specify the technical challenges associated with each. The conclusion of this paper identifies possible areas in which investment in space robotics could lead to significant advances of important technologies.

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

    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.

  17. Toward cognitive robotics

    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.

  18. Robotics for surgery.

    Howe, R D; Matsuoka, Y

    1999-01-01

    Robotic technology is enhancing surgery through improved precision, stability, and dexterity. In image-guided procedures, robots use magnetic resonance and computed tomography image data to guide instruments to the treatment site. This requires new algorithms and user interfaces for planning procedures; it also requires sensors for registering the patient's anatomy with the preoperative image data. Minimally invasive procedures use remotely controlled robots that allow the surgeon to work inside the patient's body without making large incisions. Specialized mechanical designs and sensing technologies are needed to maximize dexterity under these access constraints. Robots have applications in many surgical specialties. In neurosurgery, image-guided robots can biopsy brain lesions with minimal damage to adjacent tissue. In orthopedic surgery, robots are routinely used to shape the femur to precisely fit prosthetic hip joint replacements. Robotic systems are also under development for closed-chest heart bypass, for microsurgical procedures in ophthalmology, and for surgical training and simulation. Although results from initial clinical experience is positive, issues of clinician acceptance, high capital costs, performance validation, and safety remain to be addressed.

    Likhachev, Maxim; Arkin, Ronald C.

    2000-10-01

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

  20. Door breaching robotic manipulator

    2008-04-01

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

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

    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.

    From the viewpoint of electric motor, and hydraulic and pneumatic drivings mainly for the industrial robot operation, the present conditions and themes of engineering were explained. The actuators to be adopted to the electric robots initially were mainly stepping or DC servo motors and have recently been becoming mainly brushless DC motors. The reduction gear driving is problematic in back lash, rigidity and resonance, against which different countermeasures are studied. The direct driving, though having completely overcome those points of problem, has many other points of problem to be contrariwise overcome, eg., high accuracy resolution detecor, high torque break, rigidity maintaining method by savo alone, etc., which are advisable to be solved and developed. Because the hydraulic robots are problematic in hydraulic compressibility and change in characteristics due to oil temperature, and that the pneumatic robots are also problematic in respondability and high accuracy controllability, the research is now active in the controlling engineering.

    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.

    2011-01-01

    Surgical robotics was first utilized to facilitate neurosurgical biopsies in 1985, and it has since found application in orthopedics, urology, gynecology, and cardiothoracic, general, and vascular surgery. Surgical assistance systems provide intelligent, versatile tools that augment the physician's ability to treat patients by eliminating hand tremor and enabling dexterous operation inside the patient's body. Surgical robotics systems have enabled surgeons to treat otherwise untreatable conditions while also reducing morbidity and error rates, shortening operative times, reducing radiation exposure, and improving overall workflow. These capabilities have begun to be realized in two important realms of aortic vascular surgery, namely, flexible robotics for exclusion of complex aortic aneurysms using branched endografts, and robot-assisted laparoscopic aortic surgery for occlusive and aneurysmal disease.

    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.

    Ultimately, neurosurgery performed via a robotic interface will serve to improve the standard of a neurosurgeon's skills, thus making a good surgeon a better surgeon. In fact, computer and robotic instrumentation will become allies to the neurosurgeon through the use of these technologies in training, diagnostic, and surgical events. Nonetheless, these technologies are still in an early stage of development, and each device developed will entail its own set of challenges and limitations for use in clinical settings. The future operating room should be regarded as an integrated information system incorporating robotic surgical navigators and telecontrolled micromanipulators, with the capabilities of all principal neurosurgical concepts, sharing information, and under the control of a single person, the neurosurgeon. The eventual integration of robotic technology into mainstream clinical neurosurgery offers the promise of a future of safer, more accurate, and less invasive surgery that will result in improved patient outcome.

  8. Quantum Robots Plus Environments

    CERN Document Server

    Benioff, P

    1998-01-01

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

    In 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.

    Jacob, Brian P; Gagner, Michel

    2003-12-01

    Robotics are now being used in all surgical fields, including general surgery. By increasing intra-abdominal articulations while operating through small incisions, robotics are increasingly being used for a large number of visceral and solid organ operations, including those for the gallbladder, esophagus, stomach, intestines, colon, and rectum, as well as for the endocrine organs. Robotics and general surgery are blending for the first time in history and as a specialty field should continue to grow for many years to come. We continuously demand solutions to questions and limitations that are experienced in our daily work. Laparoscopy is laden with limitations such as fixed axis points at the trocar insertion sites, two-dimensional video monitors, limited dexterity at the instrument tips, lack of haptic sensation, and in some cases poor ergonomics. The creation of a surgical robot system with 3D visual capacity seems to deal with most of these limitations. Although some in the surgical community continue to test the feasibility of these surgical robots and to question the necessity of such an expensive venture, others are already postulating how to improve the next generation of telemanipulators, and in so doing are looking beyond today's horizon to find simpler solutions. As the robotic era enters the world of the general surgeon, more and more complex procedures will be able to be approached through small incisions. As technology catches up with our imaginations, robotic instruments (as opposed to robots) and 3D monitoring will become routine and continue to improve patient care by providing surgeons with the most precise, least traumatic ways of treating surgical disease.

  17. 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.

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

    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.

    Lindemann, M.; Maass, R.; Sauter, G.

    2015-04-01

    The total luminous flux of a light source is the complete integration of its spectral radiance distribution weighted with the photopic observer and taken over all parts of its surface and over the full solid angle of emittance. The spatial distributions are measured with various types of goniophotometers and the PTB robot goniophotometer is a new type with many unique features. It is built as an arrangement of three robots with arms of more than 6 m in length and with 7 degrees of freedom each. The extreme flexibility of the robots allows computer controlled tracks with variable radii and speeds up to 3 m and 1 m s-1, respectively. One robot aligns the light source and the two other robots move photometers and array spectrometers in their hemispheres simultaneously measuring planar illuminance and the related relative spectral distribution. The robot goniophotometer is optimized for the realisation of the luminous flux unit, the lumen and it is completely characterized in this report. The relevant properties and correction factors are explained, as well as the implementation of techniques for synchronisation and stabilisation of spatially resolved or integrated photometric and colorimetric quantities. Finally, all contributions are combined in the model of evaluation for the (total) luminous flux value and the measurement uncertainty associated with that value is evaluated in the presented uncertainty budget. The goniophotometric determination of the values for colorimetric quantities is explained for the total luminous flux and the spatially distributed radiant power.

  1. Robotic surgery in gynecology

    2015-01-01

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

    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.

  20. Evolutionary robotics – A review

    Indian Academy of Sciences (India)

    Dilip Kumar Pratihar

    2003-12-01

    In evolutionary robotics, a suitable robot control system is developed automatically through evolution due to the interactions between the robot and its environment. It is a complicated task, as the robot and the environment constitute a highly dynamical system. Several methods have been tried by various investigators to solve this problem. This paper provides a survey on some of these important studies carried out in the recent past.

  1. An architecture for ethical robots

    OpenAIRE

    2016-01-01

    Robots are becoming ever more autonomous. This expanding ability to take unsupervised decisions renders it imperative that mechanisms are in place to guarantee the safety of behaviours executed by the robot. Moreover, smart autonomous robots should be more than safe; they should also be explicitly ethical -- able to both choose and justify actions that prevent harm. Indeed, as the cognitive, perceptual and motor capabilities of robots expand, they will be expected to have an improved capacity...

  2. 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.

  3. Quantum robots plus environments.

    Energy Technology Data Exchange (ETDEWEB)

    Benioff, P.

    1998-07-23

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

  4. Salvage robotic radical prostatectomy

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Failure of non-surgical primary treatment for localized prostate cancer is a common occurrence, with rates of disease recurrence ranging from 20% to 60%. In a large proportion of patients, disease recurrence is clinically localized and therefore potentially curable. Unfortunately, due to the complex and potentially morbid nature of salvage treatment, radical salvage surgery is uncommonly performed. In an attempt to decrease the morbidity of salvage therapy without sacrificing oncologic efficacy, a number of experienced centers have utilized robotic assistance to perform minimally invasive salvage radical prostatectomy. Herein, we critically evaluate the existing literature on salvage robotic radical prostatectomy with a focus on patient selection, perioperative complications and functional and early oncologic outcomes. These results are compared with contemporary and historical open salvage radical prostatectomy series and supplemented with insights we have gained from our experience with salvage robotic radical prostatectomy. The body of evidence by which conclusions regarding the efficacy and safety of robotic salvage radical prostatectomy can be drawn comprises fewer than 200 patients with limited follow-up. Preliminary results are promising and some outcomes have been favorable when compared with contemporary open salvage prostatectomy series. Advantages of the robotic platform in the performance of salvage radical prostatectomy include decreased blood loss, short length of stay and improved visualization. Greater experience is required to confirm the long-term oncologic efficacy and functional outcomes as well as the generalizability of results achieved at experienced centers.

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

    Our artifacts are getting smarter, and a loose parallel with the evolution of animal intelligence suggests one future course for them. Computerless industrial machinery exhibits the behavioral flexibility of single-celled organisms. Today's best computer-controlled robots are like the simpler invertebrates. A thousand-fold increase in computer power in the next decade should make possible machines with reptile-like sensory and motor competence. Properly configured, such robots could do in the physical world what personal computers now do in the world of data - act on our behalf as literal-minded slaves. Growing computer power over the next half-century will allow this reptile stage to be surpassed, in stages producing robots that learn like mammals, model their world like primates, and eventually reason like humans. Depending on your point of view, humanity will then have produced a worthy successor, or transcended some of its inherited limitations and so transformed itself into something quite new.

    2017-01-01

    Transoral robotic surgery (TORS) is a technique used to treat oral, throat, and skull base cancers using a minimally invasive robotic approach through the mouth and throat. The TORS procedure allows deeper access and dissection of suspicious lesions and neoplastic growths in the oral cavity and those that extend from the throat to the base of the skull. Robotic surgery allows the surgeon to operate in tight spaces without a large open incision. This article discusses symptoms and risk factors of oral, throat, and skull base cancers; types of procedures that can be performed using the TORS approach; specialized instrumentation; patient selection; surgical advantages and disadvantages; patient benefits; and the role of the surgical team in preparing to intraoperatively care for the TORS patient.

    We consider the problem faced by a mobile robot that has to reach a given target by traveling through an unmapped region in the plane containing oriented rectangular obstacles. We assume the robot has no prior knowledge about the positions or sizes of the obstacles, and acquires such knowledge only when obstacles are encountered. Our goal is to minimize the distance the robot must travel, using the competitive ratio as our measure. We give a new randomized algorithm for this problem whose competitive ratio is O(n4/9 log n), beating the deterministic {Omega}({radical}n) lower bound of [PY], and answering in the affirmative an open question of [BRS] (which presented an optimal deterministic algorithm). We believe the techniques introduced here may prove useful in other on-line situations in which information gathering is part of the on-line process.

    2012-10-01

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

The interest of computers in surgical research and development is lesser known. Two examples are given: computer aided conception and simulation of physiologic systems. Robotics has been introduced more recently. There are three types of robotics corresponding to three types of use: targetting used by neural surgeons to localize tumors or anatomical structures, visualization used by general surgeons to hold and mobilize laparoscopes, instrumentation introduced more recently by cardiac surgeons to perform totally endoscopic cardiac operations.

Highly skilled surgeons are trained to operate and adapt to difficult conditions. They are even capable of developing intelligent mechanisms to exploit a variety of tactile, visual, and other cues. The robotic systems, however, can enhance the surgeon's capability to perform a wide variety of tasks. They cannot replace the surgeon's problem-solving ability. Instead, they will redefine his role. They will significantly enhance the surgeon's skills and dexterity by providing their complementary capabilities and an ergonomically efficient and more user-friendly working environment.

    Vallery, Heike; Duschau-Wicke, Alexander; Riener, Robert

    2010-01-01

    To enable compliant training modes with a rehabilitation robot, an important prerequisite is that any undesired human-robot interaction forces caused by robot dynamics must be avoided, either by an appropriate mechanical design or by compensating control strategies. Our recently proposed control scheme of "Generalized Elasticities" employs potential fields to compensate for robot dynamics, including inertia, beyond what can be done using closed-loop force control. In this paper, we give a simple mechanical equivalent using the example of the gait rehabilitation robot Lokomat. The robot consists of an exoskeleton that is attached to a frame around the patient's pelvis. This frame is suspended by a springloaded parallelogram structure. The mechanism allows vertical displacement while providing almost constant robot gravity compensation. However, inertia of the device when the patient's pelvis moves up and down remains a source of large interaction forces, which are reflected in increased ground reaction forces. Here, we investigate an alternative suspension: To hide not only gravity, but also robot inertia during vertical pelvis motion, we suspend the robot frame by a stiff linear spring that allows the robot to oscillate vertically at an eigenfrequency close to the natural gait frequency. This mechanism reduces human-robot interaction forces, which is demonstrated in pilot experimental results.

    Bonatti, Johannes; Vetrovec, George; Riga, Celia; Wazni, Oussama; Stadler, Petr

    2014-05-01

    Robotic technology has been used in cardiovascular medicine since the late 1990s. Interventional cardiology, electrophysiology, endovascular surgery, minimally invasive cardiac surgery, and laparoscopic vascular surgery are all fields of application. Robotic devices enable endoscopic reconstructive surgery in narrow spaces and fast, very precise placement of catheters and devices in catheter-based interventions. In all robotic systems, the operator manipulates the robotic arms from a control station or console. In the field of cardiac surgery, mitral valve repair, CABG surgery, atrial septal defect repair, and myxoma resection can be achieved using robotic technology. Furthermore, vascular surgeons can perform a variety of robotically assisted operations to treat aortic, visceral, and peripheral artery disease. In electrophysiology, ablation procedures for atrial fibrillation can be carried out with robotic support. In the past few years, robotically assisted percutaneous coronary intervention and abdominal aortic endovascular surgery techniques have been developed. The basic feasibility and safety of robotic approaches in cardiovascular medicine has been demonstrated, but learning curves and the high costs associated with this technology have limited its widespread use. Nonetheless, increased procedural speed, accuracy, and reduced exposure to radiation and contrast agent in robotically assisted catheter-based interventions, as well as reduced surgical trauma and shortened patient recovery times after robotic cardiovascular surgery are promising achievements in the field.

    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.

  18. Probabilistic approaches to robotic perception

    Ferreira, João Filipe

    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...

  1. Fruit harvesting robots in Japan

    Science.gov (United States)

    Kondo, N.; Monta, M.; Fujiura, T.

    We have developed harvesting robots for tomato /1/, petty-tomato, cucumber /2/ and grape /3/ 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.

    Robotic telescopes are revolutionizing the way astronomers collect their dataand conduct sky surveys. This chapter begins with a discussion of principles thatguide the process of designing, constructing, and operating telescopes andobservatories that offer a varying degree of automation, from instruments remotelycontrolled by observers to fully autonomous systems requiring no humansupervision during their normal operations. Emphasis is placed on designtrade-offs involved in building end-to-end systems intended for a wide range ofscience applications. The second part of the chapter contains descriptions ofseveral projects and instruments, both existing and currently under development.It is an attempt to provide a representative selection of actual systems thatillustrates state of the art in technology, as well as important ideas and milestonesin the development of the field. The list of presented instruments spans the fullrange in size starting from small all-sky monitors, through midrange robotic andsurvey telescopes, and finishing with large robotic instruments and surveys.Explosive growth of telescope networking is enabling entirely new modesof interaction between the survey and follow-up observing. Increasingimportance of standardized communication protocols and software is stressed.These developments are driven by the fusion of robotic telescope hardware,massive storage and databases, real-time knowledge extraction, and datacross-correlation on a global scale. The chapter concludes with examplesof major science results enabled by these new technologies and futureprospects.

  10. 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.

    2010-01-01

    The three laws of Robotics first appeared together in Isaac Asimov's story 'Runaround' after being mentioned in some form or the other in previous works by Asimov. These three laws commonly known as the three laws of robotics are the earliest forms of depiction for the needs of ethics in Robotics. In simplistic language Isaac Asimov is able to explain what rules a robot must confine itself to in order to maintain societal sanctity. However, even though they are outdated they still represent some of our innate fears which are beginning to resurface in present day 21st Century. Our society is on the advent of a new revolution; a revolution led by advances in Computer Science, Artificial Intelligence & Nanotechnology. Some of our advances have been so phenomenal that we surpassed what was predicted by the Moore's law. With these advancements comes the fear that our future may be at the mercy of these androids. Humans today are scared that we, ourselves, might create something which we cannot control. We may ...

    Alkatout, Ibrahim; Mettler, Liselotte; Maass, Nicolai; Ackermann, Johannes

    2016-01-01

    Robotic surgery is the most dynamic development in the sector of minimally invasive operations currently. It should not be viewed as an alternative to laparoscopy, but as the next step in a process of technological evolution. The advancement of robotic surgery, in terms of the introduction of the Da Vinci Xi, permits the variable use of optical devices in all four trocars. Due to the new geometry of the "patient cart," an operation can be performed in all spatial directions without re-docking. Longer instruments and the markedly narrower mechanical elements of the "patient cart" provide greater flexibility as well as access similar to those of traditional laparoscopy. Currently, robotic surgery is used for a variety of indications in the treatment of benign gynecological diseases as well as malignant ones. Interdisciplinary cooperation and cooperation over large geographical distances have been rendered possible by telemedicine, and will ensure comprehensive patient care in the future by highly specialized surgery teams. In addition, the second operation console and the operation simulator constitute a new dimension in advanced surgical training. The disadvantages of robotic surgery remain the high costs of acquisition and maintenance as well as the laborious training of medical personnel before they are confident with using the technology.

  14. Toward Psycho-robots

    2007-01-01

    We try to perform geometrization of psychology by representing mental states, ideas, by points of a metric space, mental space. Evolution of ideas is described by dynamical systems in metric mental space. We apply the mental space approach for modeling of flows of unconscious and conscious information in the human brain. In a series of models, Models 1-4, we consider cognitive systems with increasing complexity of psychological behavior determined by structure of flows of ideas. Since our models are in fact models of the AI-type, one immediately recognizes that they can be used for creation of AI-systems, which we call psycho-robots, exhibiting important elements of human psyche. Creation of such psycho-robots may be useful improvement of domestic robots. At the moment domestic robots are merely simple working devices (e.g. vacuum cleaners or lawn mowers) . However, in future one can expect demand in systems which be able not only perform simple work tasks, but would have elements of human self-developing psy...

    2016-03-01

    Due to the improved economic situation in the high technology sectors, work on the creation of industrial robots and special mobile robotic systems are resumed. Despite this, the robotic control systems mostly remained unchanged. Hence one can see all advantages and disadvantages of these systems. This is due to lack of funds, which could greatly facilitate the work of the operator, and in some cases, completely replace it. The paper is concerned with the complex machine vision of robotic system for monitoring of underground pipelines, which collects and analyzes up to 90% of the necessary information. Vision Systems are used to identify obstacles to the process of movement on a trajectory to determine their origin, dimensions and character. The object is illuminated in a structured light, TV camera records projected structure. Distortions of the structure uniquely determine the shape of the object in view of the camera. The reference illumination is synchronized with the camera. The main parameters of the system are the basic distance between the generator and the lights and the camera parallax angle (the angle between the optical axes of the projection unit and camera).

  17. [Radical prostatectomy - pro robotic].

    Science.gov (United States)

    Gillitzer, R

    2012-05-01

    Anatomical radical prostatectomy was introduced in the early 1980s by Walsh and Donker. Elucidation of key anatomical structures led to a significant reduction in the morbidity of this procedure. The strive to achieve similar oncological and functional results to this gold standard open procedure but with further reduction of morbidity through a minimally invasive access led to the establishment of laparoscopic prostatectomy. However, this procedure is complex and difficult and is associated with a long learning curve. The technical advantages of robotically assisted surgery coupled with the intuitive handling of the device led to increased precision and shortening of the learning curve. These main advantages, together with a massive internet presence and aggressive marketing, have resulted in a rapid dissemination of robotic radical prostatectomy and an increasing patient demand. However, superiority of robotic radical prostatectomy in comparison to the other surgical therapeutic options has not yet been proven on a scientific basis. Currently robotic-assisted surgery is an established technique and future technical improvements will certainly further define its role in urological surgery. In the end this technical innovation will have to be balanced against the very high purchase and running costs, which remain the main limitation of this technology.

    The Soldier Universal Robot Controller (SURC) is a modular OCU designed for simultaneous control of heterogeneous unmanned vehicles. It has a well defined, published API., defined using XML schemas, that allows other potential users of the system to develop their own modules for rapid integration with SURC. The SURC architecture is broken down into three layers: User Interface, Core Functions, and Transport. The User Interface layer is the front end module which provides the human computer interface for user control of robots. The Core layer is further divided into the following modules: Capabilities, Tactical, Mobility, and World Model. The Capabilities module keeps track of the known robots and provides a list of specifications and services. The Mobility module provides path planning via D*, while the Tactical module provides higher level mission planning (multi-agent/multi-mission) capabilities for collaborative operations. The World Model module is a relational database which stores world model objects. Finally, a Transport module provides translation from the SURC architecture to the robot specific messaging protocols (such as JAUS). This allows fast integration of new robot protocols into an existing SURC implementation to enable a new system to rapidly leverage existing SURC capabilities. The communication between different modules within the SURC architecture is done via XML. This gives developers and users the flexibility to extend existing messages without breaking backwards compatibility. The modularity of SURC offers users and developers alike the capability to create custom modules and plug them into place, as long as they follow the pre defined messaging API for that module.

    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.

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

    Cooperation and competition among stand-alone swarm agents increase collective fitness of the whole system. A principally new kind of collective systems is demonstrated by some bacteria and fungi, when they build symbiotic organisms. Symbiotic life forms emerge new functional and self-developmental capabilities, which allow better survival of swarm agents in different environments. In this paper we consider energy foraging scenario for two robotic species, swarm robots and symbiotic robot organism.

    Mert Gürgen

    2016-09-01

    Full Text Available This article describes a sophisticated determination and presentation of a workspace volume for a delta robot, with consideration of its kinematic behavior. With the help of theoretical equations, optimization is performed with the aid of the stiffness and dexterity analysis. Theoretical substructure is coded in Matlab and three-dimensional (3D data for delta robot are developed in computer-aided design (CAD environment. In later stages of the project, both 3D and theoretical data are linked together and thus, with the changing design parameter of the robot itself, the Solidworks CAD output adapts and regenerates output with a new set of parameters. To achieve an optimum workspace volume with predefined parameters, a different set of robot parameters are iterated through design optimization in Matlab, and the delta robot design is finalized and illustrated in the 3D CAD environment, Solidworks. This study provides a technical solution to accomplish a generic delta robot with optimized workspace volume.

  13. Robotic Surgery in Gynecologic Oncology

    Directory of Open Access Journals (Sweden)

    Robert DeBernardo

    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.

    As surgical and anaesthetic procedures become more complex, operating theatres need to be larger and multi-purpose to accommodate specialist equipment such as the Da Vinci Robot. The Da Vinci theatre at The Royal Wolverhampton NHS trust (RWT) is a modern theatre equipped and designed specifically for robotic surgery. When we first began to perform robotic surgery at RWT we faced many challenges on how to maximise the space available to us, whilst striving to minimise the chance of desterilisation.

    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.

  13. Robotic systems in spine surgery.

    Science.gov (United States)

    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.

    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.

    1991-01-01

    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.

    2000-08-01

    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.

    The capacity through the use of robots with on board visual, NBC and HAZMAT sensors to rapidly and continuously screen convoys and staged exposed assets would be a force multiplier and measurably improve base and force protection at both inbound and outbound DOD and commercial facilities. This paper chronicles our experiment with the ODIS robot at the Ports of Los Angeles (POLA) and Long Beach (POLB) in July of 2003. POLA & POLB are responsible for moving over 30% of the United States trade goods. Queues of 54" container trucks routinely exceed 100 trucks, extending for over a mile from the port entrances. Spotted equipment and convoys at staging areas are a high visibility and value assets to a terrorist incident. The POLA/POLB scenario is also representative of TRANSCOM operations at the port of Basra during current operation in Iraq. The California Highway Patrol is responsible for physically inspecting these vehicles for roadworthiness and contraband, a dangerous and dirty job. We will also discuss the use of ODIS robots for this task.

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.

    Almost all robot navigation systems work indoors. Outdoor robot navigation systems offer the potential for new application areas. The biggest single obstacle to building effective robot navigation systems is the lack of accurate wide-area sensors for trackers that report the locations and orientations of objects in an environment. Active (sensor-emitter) tracking technologies require powered-device installation, limiting their use to prepared areas that are relative free of natural or man-made interference sources. The hybrid tracker combines rate gyros and accelerometers with compass and tilt orientation sensor and DGPS system. Sensor distortions, delays and drift required compensation to achieve good results. The measurements from sensors are fused together to compensate for each other's limitations. Analysis and experimental results demonstrate the system effectiveness. The paper presents a field experiment for a low-cost strapdown-IMU (Inertial Measurement Unit)/DGPS combination, with data processing for the determination of 2-D components of position (trajectory), velocity and heading. In the present approach we have neglected earth rotation and gravity variations, because of the poor gyroscope sensitivities of our low-cost ISA (Inertial Sensor Assembly) and because of the relatively small area of the trajectory. The scope of this experiment was to test the feasibility of an integrated DGPS/IMU system of this type and to develop a field evaluation procedure for such a combination.

    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.

    Full Text Available Dynamic Partial Reconfiguration (DPR of FPGAs presents many opportunities for application design flexibility, enabling tasks to dynamically swap in and out of the FPGA without entire system interruption. In this paper, we will implement a line follower robot for the white line as well as for black line; both these modules will be programmed in VHDL. The robot will dynamically reconfigure the FPGA in the run-time while the robot senses black line after white line or vice-versa. This design includes two modules one is static and the other is partially reconfigurable regions (PRR which is a dynamic region. The controllers are the static modules used for controlling the flow of data to and from the reconfigurable modules to the external world (host environment through busmacros. Whereas white line and black line modules are designed as dynamic modules. Different hardware modules will be used such as Sensors and actuators , all these modules will be interfaced using FPGA controller. The speed of motor is controlled using pulse width modulation (PWM using VHDL

    2003-12-01

    A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have been shown to decrease operative times significantly. It is expected that with further refinements and development of adjunct technologies, the technique of computer-enhanced endoscopic cardiac surgery will evolve and may prove to be beneficial for many patients. Robotic technology has provided benefits to cardiac surgery. With improved optics and instrumentation, incisions are smaller. The ergometric movements and simulated three-dimensional optics project hand-eye coordination for the surgeon. The placement of the wristlike articulations at the end of the instruments moves the pivoting action to the plane of the mitral annulus. This improves dexterity in tight spaces and allows for ambidextrous suture placement. Sutures can be placed more accurately because of tremor filtration and high-resolution video magnification. Furthermore, the robotic system may have potential as an educational tool. In the near future, surgical vision and training systems might be able to model most surgical procedures through immersive technology. Thus, a "flight simulator" concept emerges where surgeons may be able to practice and perform the operation without a patient. Already, effective curricula for training teams in robotic surgery exist. Nevertheless, certain constraints continue to limit the advancement to a totally endoscopic computer-enhanced mitral valve operation. The current size of the instruments, intrathoracic instrument collisions, and extrathoracic "elbow" conflicts still can limit dexterity. When smaller instruments are developed, these restraints may be resolved. Furthermore, a working port incision is still required for

  19. An Ultrasound Robotic System Using the Commercial Robot UR5

    2016-02-01

    Full Text Available The use of robots in health care has increased dramatically over the last decade. One area of research has been to use robots to conduct ultrasound examinations, either controlled by a physician or autonomously. This paper examines the possibility of using the commercial robot UR5 from Universal Robots to make a tele-operated robotic ultrasound system. Physicians diagnosing patients using ultrasound probes are prone to repetitive strain injuries, as they are required to hold the probe in uncomfortable positions and exert significant static force. The main application for the system is to relieve the physician of this strain by letting the them control a robot that holds the probe. A set of requirements for the system is derived from the state-of-the-art systems found in the research literature. The system is developed through a low-level interface for the robot, effectively building a new software framework for controlling it. Compliance force control and forward flow haptic control of the robot was implemented. Experiments are conducted to quantify the performance of the two control schemes. The force control is estimated to have a bandwidth of 16.6 Hz, while the haptic control is estimated to have a bandwidth of 65.4 Hz for the position control of the slave and 13.4 Hz for the force control of the master. Overall, the system meets the derived requirements and the main conclusion is that it is feasible to use the UR5 robot for robotic ultrasound applications.

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

    2002-07-01

    The aim of micro-robotics is to study, design, realize and control micro-robots. The underlying scientifical problems concern the miniaturization, the design and control of these micro-robots which requires a strongly pluri-disciplinary approach. In the micro-world, the classical laws of physics cannot be applied in the same way as in the macro-world: forces usually negligible, like the adhesion, electrostatic, Van der Waals forces etc.. have a considerable effect and influence at these scales and are not easily taken into consideration in models. Thus such models of micro-robots are difficult to build and are in general incomplete. The dynamical behaviour of all the components is strongly non-linear and requires adapted control laws. Thus the experimental approach is of prime importance in order to completely reanalyze the main functions of the robot: locomotion, gripping, manipulation. The scientifical problem comprises several aspects and refers to several scientific communities. Among these aspects, this book has retained the essential ones: the miniaturization, the design and the control. Content: 1 - the problems of micro-robotics; 2 - the state-of-the-art; 3 - micro-technologies; 4 - micro-actuators; 5 - micro-actuators in shape memory alloys for micro-robotics; 6 - piezoelectric micro-actuators; 7 - micro-gripping and micro-manipulation; 8 - distributed micro-robots based on silicon technology.

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

    Kazanzides, Peter

    2009-01-01

    The use of robots in medicine is increasing, leading to the call for specific safety standards. This is a challenging endeavor, however, because the patient must usually be placed in the robot's workspace and the medical staff must frequently interact with the robot. Although specific safety standards for medical robots do not yet exist, there are several medical device standards and well-established principles of risk analysis and safety design that can and should be applied. This paper presents a tutorial overview of safety design for medical robots, starting with a discussion of high-level safety requirements, followed by methods for risk assessment (or hazard analysis) and a brief discussion of some sample safety strategies.

    2012-07-01

    Robotic surgery is gaining widespread popularity due to advantages such as reduced blood loss, reduced postoperative pain, shorter hospital stay and better visualisation of fine structures. Robots are being used in urological, cardiac, thoracic, orthopaedic, gynaecological and general surgery. Robotic surgery received US Food and Drug Administration approval for use in gynaecological surgery in 2005. The various gynaecological robotic operations being performed are myomectomy, total and supracervical hysterectomy, ovarian cystectomy, sacral colpopexy, tubal reanastomosis, lymph node dissection, surgery of retroperitoneal ectopic pregnancy, Moskowitz procedure and endometriosis surgery. The anaesthetic considerations include difficult access to the patient intraoperatively, steep Trendelenburg position, long surgical duration and the impact of pneumoperitoneum. We highlight the complications encountered in these surgeries and methods to prevent these complications. Robotic gynaecological surgery can be safely performed after considering the physiological effects of the steep Trendelenburg position and of pneumoperitoneum. The benefits of the surgical procedure should be weighed against the risks in patients with underlying cardiorespiratory problems.

    2004-07-01

    This paper will present the concept of utilizing various mobile robotic platforms for homeland security. Highly specialized mobile robots equipped with the proper sensors and data processing capabilities have the ability to provide security and surveillance for a wide variety of applications. Large infrastructure components, such as bridges, pipelines, dams, and electrical power grids pose severe challenges for monitoring, surveillance, and protection against man-made and natural hazards. The structures are enormous, often with awkward and dangerous configurations that make it difficult, if not impossible, for continuous human surveillance. Properly outfitted robots have the potential to provide long-term surveillance without requiring continuous human supervision. Furthermore, these robotic platforms can have disaster mitigation capabilities such as evaluation of infrastructure integrity at the disaster site. The results presented will include proof-of-concept robotic platforms equipped with various sensor arrays, as well as discussion of design criteria for numerous homeland security applications.

  20. Teleautonomous guidance for mobile robots

    Science.gov (United States)

    Borenstein, J.; Koren, Y.

    1990-01-01

    Teleautonomous guidance (TG), a technique for the remote guidance of fast mobile robots, has been developed and implemented. With TG, the mobile robot follows the general direction prescribed by an operator. However, if the robot encounters an obstacle, it autonomously avoids collision with that obstacle while trying to match the prescribed direction as closely as possible. This type of shared control is completely transparent and transfers control between teleoperation and autonomous obstacle avoidance gradually. TG allows the operator to steer vehicles and robots at high speeds and in cluttered environments, even without visual contact. TG is based on the virtual force field (VFF) method, which was developed earlier for autonomous obstacle avoidance. The VFF method is especially suited to the accommodation of inaccurate sensor data (such as that produced by ultrasonic sensors) and sensor fusion, and allows the mobile robot to travel quickly without stopping for obstacles.
