    Introducción: La cirugía mínimamente invasiva en urología avanza rápidamente y la cirugía laparo-endoscópica a través de puerto único (LESS) no es la excepción. Esta técnica por vía laparoscópica presenta mucha dificultad y requiere de un cirujano laparoscópico experimentado debido a la falta de triangulación y el cruce de los instrumentos. Los beneficios del sistema quirúrgico da Vinci® han sido introducidos recientemente en LESS. Presentamos dos casos de nefrectomía LESS asistida por robot....

    2014-01-01

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

  5. 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.

    2011-04-01

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

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

  1. Producción y tratamiento de películas de Si1-xGex mediante técnicas asistidas por láser de excímero

    Directory of Open Access Journals (Sweden)

    Castro, J.

    1998-04-01

    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.

    Full Text Available Se ha construido y caracterizado un foto-reactor tubular de sección circular para su aplicación al tratamiento de aguas subterráneas contaminadas con Arsénico, As(V, utilizando las técnica de la Remoción de Arsénico por Oxidación Solar (RAOS. El concentrador solar que posee una capacidad de radiación equivalente a 2,8 soles, fue construido reciclando materiales desechados: tubos de vidrio proveniente de lámparas de Ne y tubos de desagüe sanitario de 6” (PVC, recubiertos por láminas de aluminio. Pruebas simultáneas sin agitación,realizadas aplicando la radiación UV solar a aguas sintéticas, demostraron que la remoción de As(V en el foto-reactor es más rápida queen un tubo de vidrio sólo y en una botella PET de 2 litros, logrando remociones mayores al 98% en todos los casos. Los tiempos para la aparición de los flóculos de complejo Fe-citrato fueron de 40, 50 y 90 min respectivamente, para intensidades de radiación UVA integral (290-390 nm entre 50 y 70 Wm-2. Pruebas de irradiación seguidas de agitación controlada a 30-33 s-1 de gradiente de velocidad, demostraron que el foto-reactor acelera el proceso de formación de flóculos fácilmente sedimentables al cabo de 20-30 min de agitación. Los tiempos de irradiación óptimos para el foto-reactor, el tubo y la botella son de 15, 25 y 60 min, respectivamente. Pruebas en régimen de flujo continuo en un foto-reactor de aproximadamente 1 m2 de área, con un tiempo de residencia hidráulica (igual al tiempo de irradiación de 15 min, mostraron la formación inmediata de flóculos fácilmente sedimentables cuando se agitan a 33 s-1 durante 20-30 min, lográndose una remoción del 98,36% una concentración remanente de 16,5 mgL-1 de As(V en aguas decantadas. Esto significa que se pueden tratar aproximadamente 130 Lm-2 en una jornada de 6 horas de radiación UVA de 50-70 Wm-2 de intensidad.

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

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

    Ruisánchez, Esteban

    2014-06-01

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

Se usan como criterios de optimización, la minimización del desplazamiento angular de los eslabones con mayor consumo de energía y la minimización del valor absoluto máximo de la aceleración angular de los eslabones. En ambos casos se determinó una trayectoria que disminuye el consumo de energía en más de un 25% respecto de otros métodos planteados en la literatura, a la vez que se mejora el comportamiento dinámico del sistema evitando variaciones en la velocidad y la aceleración durante la fase de trasferencia, además de aumentar la precisión y exactitud de la posición del pie. Abstract: It presents a method of multi-objective optimization, applied to energy consumption of open kinematic chains, analyzing the case of the movement of an extremity of a walking electro- hydraulic robot. To demonstrate the effectiveness of the proposed method, it is applied in two cases of displacement. The first case shows the movement of the extremity without obstacles in its workspace and the second includes the evasion of an obstacle. The minimization of angular displacement of the links with higher energy consumption and the minimization of the maximum absolute value of the angular acceleration of the links are used as optimization criteria. In both cases a trajectory that reduces energy consumption by more than 25% over the other methods proposed in the literature, at the same time the dynamic behavior of the system by avoiding variations in the speed and the acceleration is improved

    Full Text Available OBJETIVO: Avaliar as vantagens da cirurgia com navegação na revisão cirúrgica de deformidades vertebrais, verificando a acurácia deste método. MÉTODO: Foram revisados cincos pacientes com deformidades vertebrais que tiveram intercorrências na primeira cirurgia. Esses pacientes foram submetidos a um estudo de tomografia computadorizada (TC com cortes de 2mm da coluna vertebral antes da segunda cirurgia. Nos cinco pacientes submetidos a reabordagem cirúrgica procedeu-se a instrumentação posterior com auxílio da navegação. Foram 84 parafusos pediculares implantados, sendo que 33 destes parafusos foram assistidos por computação. A navegação foi empregada nos níveis da deformidade vertebral onde a anatomia apresentava-se alterada inviabilizando o correto uso dos parâmetros anatômicos para inserção de parafusos pediculares. Nos demais níveis onde era possível a correta identificação desses parâmetros anatômicos foi utilizada a técnica padrão. A TC pós-operatória foi realizada para aferição do posicionamento dos parafusos pediculares. Avaliamos os resultados obtidos no posicionamento com e sem o uso da navegação. O tempo de fluoroscopia e o tempo da cirurgia também foram comparados com o padrão ouro da literatura. RESULTADOS: Dos 33 parafusos implantados com navegação observou-se uma acurácia de 94%, com uma taxa de violação pedicular de 6%. CONCLUSÕES: O uso da navegação é importante nas revisões cirúrgicas das deformidades vertebrais com anatomia alterada, influenciando no bom resultado final da cirurgia.OBJETIVO: Evaluar las ventajas de la cirugía con navegación en reoperación por deformidades vertebrales, verificando la precisión de este método.

    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.

    La antracnosis causada por Colletotrichum lindemuthianum puede llegar a generar pérdidas hasta del 95% de la producción en fríjol (Phaseolus vulgaris L., por eso es considerada una de las enfermedades más limitantes. Con el presente trabajo se inició un programa de mejoramiento utilizando selección asistida por marcadores. Se usó como parental resistente el cultivar Mesoamericano G2333, para incorporar a fríjoles volubles comerciales de Colombia los genes Co-5 y Co-42 , que confieren resistencia a C. lindemuthianum. Se obtuvieron progenies RC1F1 provenientes de cruces entre G2333 y siete parentales volubles tipo Bola roja y Rojo moteado cultivados en zonas productoras de fríjol de Cundinamarca y Boyacá. La selección de plantas RC1F1 se realizó con los marcadores moleculares SCAR SAB3 y SAS13, ligados a los genes Co-5 y Co-42 , respectivamente. En la evaluación genotípica de 1.271 plantas RC1F1, 608 amplificaron con SAB3 y 603 con SAS13. La segregación para cada marcador se ajustó a la razón 1:1 esperada en pruebas de chi-cuadrado (X2 = 2,38, P= 0,12 para SAB3 y X2 = 3,32, P= 0,07 para SAS13. Un total de 299 plantas RC1F1 amplificaron con ambos SCAR, ajustándose a la razón esperada (X2= 1,11, P= 0,78 y confirmando la segregación independiente. Estas plantas fueron seleccionadas para continuar el programa de mejoramiento, ya que se espera que porten los genes Co-5 y Co-42. Se logró implementar la selección asistida por marcadores para antracnosis, y acelerar la introducción y piramidación de genes de resistencia en fríjol de importancia económica en Colombia.

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

    Full Text Available 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.

    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.

  9. Imitation of gestures by robotic arms: a quality assessment approach; Imitacion de gestos por brazos roboticos: Una propuesta para evaluar su calidad

    Nope-Rodriguez, S.; Loaiza-Correa, H.; Caicedo-Bravo, E.

    2010-07-01

    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.

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

    Robotics education courses are rapidly spreading throughout the nation's colleges and universities. Engineering schools are offering robotics courses as part of their mechanical or manufacturing engineering degree program. Two year colleges are developing an Associate Degree in robotics. In addition to regular courses, colleges are offering seminars in robotics and related fields. These seminars draw excellent participation at costs running up to $200 per day for each participant. The last one drew 275 people from Texas to Virginia. Seminars are also offered by trade associations, private consulting firms, and robot vendors. IBM, for example, has the Robotic Assembly Institute in Boca Raton and charges about $1,000 per week for course. This is basically for owners of IBM robots. Education (and training) can be as short as one day or as long as two years. Here is the educational pattern that is developing now

    2018-04-09

    This description of "soft robotics" is not intended to be a conventional review, in the sense of a comprehensive technical summary of a developing field. Rather, its objective is to describe soft robotics as a new field-one that offers opportunities to chemists and materials scientists who like to make "things" and to work with macroscopic objects that move and exert force. It will give one (personal) view of what soft actuators and robots are, and how this class of soft devices fits into the more highly developed field of conventional "hard" robotics. It will also suggest how and why soft robotics is more than simply a minor technical "tweak" on hard robotics and propose a unique role for chemistry, and materials science, in this field. Soft robotics is, at its core, intellectually and technologically different from hard robotics, both because it has different objectives and uses and because it relies on the properties of materials to assume many of the roles played by sensors, actuators, and controllers in hard robotics. © 2018 Wiley-VCH Verlag GmbH & Co.

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

The lack of uptake may be (at least partly) because in many cases there is either no compelling economic benefit......, or there is a benefit but it is not recognized. The aim of this chapter is to quantify the economic benefits from the application of agricultural robots under a specific condition where such a benefit is assumed to exist, namely the case of early seeding and re-seeding in sugar beet.

    Directory of Open Access Journals (Sweden)

    Ana Mª Rivas

    2009-10-01

    Full Text Available This article studies the position of single mothers by choice ‒SMBC‒ in the stage of access to motherhood, that is, from the moment they decide to start their family projects until their sons/daughters are incorporated into their homes. The hypothesis maintained here is that the SMBC empowerment degree varies throughout time so that, for example, those who have opted for international adoption are, on its initial stage, in a situation of vulnerability that can subside when they finally manage to be mothers. We want to state here that in order to analyze the socio-political positions of these women we have to consider not only variables as age, education, income, etc., but also their different access channels to motherhood as well as the stage in the development of their family projects, that is, their temporal dimension.

En el desarrollo de la misma quedó demostrado, que una vez conocido el modelogeométrico tridimensional de un ensamble, la aplicación de criterios tecnológicos y geométricos alproceso inverso de desensamble y su posterior tratamiento con el método de algoritmosevolutivos, genera una planificación optimizada del su proceso de ensamble mecánico. Laintegración de la información permite disminuir el número de secuencias a evaluar y de elementosa procesar, con lo que se evita la generación y evaluación de todas las secuencias posibles con laconsecuente disminución del tiempo de procesamiento. Como resultado de la aplicación delmodelo integrado propuesto, se obtiene la planificación del proceso de ensamble mecánico conuna reducción del tiempo de ensamble debido a que en las secuencias de ensamble obtenidas sereduce el número de cambios de dirección de ensamble, los cambios de herramientas y de puestosde 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.Palabras claves: ensamble mecánico, algoritmos genéticos, optimización multiobjetivo.____________________________________________________________________________AbstractThis work deals with the combinatorial problem of generating and optimizing feasible assemblysequences and doing the process planning involving tools and work places. The assembly sequencesare obtained from a 3D model of the assembled parts based on mating conditions along with a setof technological criteria, which allows automatically analyzing and generating the sequences. Thegenerated assembly sequences are preprocessed and optimized for the assembly Process Planningusing Genetic Algorithms.

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

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

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

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

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

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

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

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 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.

    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

Luego, continuaron varios estudios realizados en diferentes países, Roy et al. (1956, Basirov (1964, Allahverdiev (1969 y Sahana y Roy (1972. Sin embargo, la ausencia de un procesamiento tecnológico adecuado del esperma en lo que se refiere a los diluyentes, el de tiempo de equilibración, concentración de glicerol, métodos de congelación y la falta de un estándar adecuado llevó a resultados pobres y variables.

    2009-11-17

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

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

    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.

    Full Text Available En este trabajo se presenta al robot paralelo PARALLIX LKF-2040 desarrollado en la Instituto Politécnico Nacional y actualmente comercializado en Instituciones de Educación Superior para fortalecer la enseñanza de la mecatrónica. Este mecanismo posee una plataforma fija y otra móvil. Los actuadores están montados en la plataforma fija, reduciendo el cableado y manteniéndolo fuera del espacio de trabajo. La plataforma móvil es el elemento efector y puede ser posicionada en un amplio espacio de trabajo. La estructura del manipulador es ligera, simplificando la dinámica y minimizando el peso a desplazar. Lo anterior, permite utilizar el par generado por los motores sólo para el desplazamiento de la carga. El robot PARALLIX LKF-2040 tiene sus orígenes en la configuración del robot tipo Delta pero tiene articulaciones rotacionales en lugar de esféricas, proporcionando un espacio de trabajo más amplio. Primeramente, se presenta el concepto de robot paralelo y sus ventajas respecto a los robots convencionales tipo serial. Se muestra la estructura geométrica de un robot paralelo tipo 3RSS y se encuentra la solución de su cinemática inversa. También, se presentan los resultados obtenidos del análisis del espacio de trabajo y el diseño de una arquitectura de control de tres ejes para servomotores con encoder incremental en cuadratura. Además, se proponen técnicas novedosas basadas en análisis de imágenes para determinar la precisión y la repetibilidad del robot, así como la rigidez bajo diferentes condiciones de carga.

    The foundation of surgical robotics is in the development of the robotic arm. This is a thorough review of the literature on the nature and development of this device with emphasis on surgical applications. We have reviewed the published literature and classified robotic arms by their application: show, industrial application, medical application, etc. There is a definite trend in the manufacture of robotic arms toward more dextrous devices, more degrees-of-freedom, and capabilities beyond the human arm. da Vinci designed the first sophisticated robotic arm in 1495 with four degrees-of-freedom and an analog on-board controller supplying power and programmability. von Kemplen's chess-playing automaton left arm was quite sophisticated. Unimate introduced the first industrial robotic arm in 1961, it has subsequently evolved into the PUMA arm. In 1963 the Rancho arm was designed; Minsky's Tentacle arm appeared in 1968, Scheinman's Stanford arm in 1969, and MIT's Silver arm in 1974. Aird became the first cyborg human with a robotic arm in 1993. In 2000 Miguel Nicolalis redefined possible man-machine capacity in his work on cerebral implantation in owl-monkeys directly interfacing with robotic arms both locally and at a distance. The robotic arm is the end-effector of robotic systems and currently is the hallmark feature of the da Vinci Surgical System making its entrance into surgical application. But, despite the potential advantages of this computer-controlled master-slave system, robotic arms have definite limitations. Ongoing work in robotics has many potential solutions to the drawbacks of current robotic surgical systems.

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

    1992-01-01

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

    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

    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.

    Klibansky, David; Rothstein, Richard I

    2012-09-01

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

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

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

    Robotic systems were introduced 15 years ago to support complex endoscopic procedures. The technology is increasingly used in gastro-intestinal surgery. In this article, literature on experimental- and clinical research is reviewed and ergonomic issues are discussed. literature review was based on Medline search using a large variety of search terms, including e.g. robot(ic), randomized, rectal, oesophageal, ergonomics. Review articles on relevant topics are discussed with preference. There is abundant evidence of supremacy in performing complex endoscopic surgery tasks when using the robot in an experimental setting. There is little high-level evidence so far on translation of these merits to clinical practice. Robotic systems may appear helpful in complex gastro-intestinal surgery. Moreover, dedicated computer based technology integrated in telepresence systems opens the way to integration of planning, diagnostics and therapy. The first high tech add-ons such as near infrared technology are under clinical evaluation. Copyright © 2014 Elsevier Ltd. All rights reserved.

  7. Toward cognitive robotics

    Science.gov (United States)

    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.

  8. Future of robotic surgery.

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

    2013-01-01

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

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

    The application of robots in the harsh environments in which TELEMAN equipment will have to operate has large benefits, but also some drawbacks. The main benefit is the ability gained to perform tasks where people cannot go, while there is a possibility of inflicting damage to the equipment handled by the robot, and the plant when mobile robots are involved. The paper describes the types of possible damage and the precautions to be taken in order to reduce the frequency of the damaging events. A literature study for the topic only gave some insight into examples, but no means for a systematic treatment of the topic. (au) 16 refs

  18. ROBOT LITERACY AN APPROACH FOR SHARING SOCIETY WITH INTELLIGENT ROBOTS

    Directory of Open Access Journals (Sweden)

    2013-12-01

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

    This thesis focuses on continuum robots based on pneumatic muscle technology. We introduce a novel approach to use these muscles as limbs of lightweight legged robots. The flexibility of the continuum legs of these robots offers the potential to perform some duties that are not possible with classical rigid-link robots. Potential applications are as space robots in low gravity, and as cave explorer robots. The thesis covers the fabrication process of continuum pneumatic muscles and limbs. It also provides some new experimental data on this technology. Afterwards, the designs of two different novel continuum robots - one tripod, one quadruped - are introduced. Experimental data from tests using the robots is provided. The experimental results are the first published example of locomotion with tripod and quadruped continuum legged robots. Finally, discussion of the results and how far this technology can go forward is presented.

    2015-01-01

    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.

    Full Text Available The application of robotics to Vascular surgery has not progressed as rapidly as of endovascular technology, but this is changing with the amalgamation of these two fields. The advent of Endovascular robotics is an exciting field which overcomes many of the limitations of endovascular therapy like vessel tortuosity and operator fatigue. This has much clinical appeal for the surgeon and hold significant promise of better patient outcomes. As with most newer technological advances, it is still limited by cost and availability. However, this field has seen some rapid progress in the last decade with the technology moving into the clinical realm. This review details the development of robotics, applications, outcomes, advantages, disadvantages and current advances focussing on Vascular and Endovascular robotics

    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.

    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.

  18. Robots in Elderly Care

    Full Text Available Low birth rate and the long life expectancy represent an explosive mixture, resulting in the rapid aging of population. The costs of healthcare in the grey society are increasing dramatically, and soon there will be not enough resources and people for care. This context requires conceptually new elderly care solutions progressively reducing the percentages of the human-based care. Research on robot-based solutions for elderly care and active ageing aims to answer these needs. From a general perspective, robotics has the power to completely reshape the landscape of healthcare both in its structure and its operation. In fact, the long-term sustainability of healthcare systems could be addressed by automation powered by digital health technologies, such as artificial intelligence, 3D-printing or robotics. The latter could take over monotonous work from healthcare workers, which would allow them to focus more on patients and to have lesser workload. Robots might be used in elder care with several different aims. (i Robots may act as caregivers, i.e. assist the elderly, (ii they can provide remainders and instructions for activities of daily life and safety, and/or assist their carers in daily tasks; (iii they can help monitor their behaviour and health; and (iv provide companionship, including entertainment and hobbies, reminiscence and social contact. The use of Robots with human subjects/patients raise several sensitive questions. First of all, robots may represent information hubs, and can collect an incredible amount of data about the subjects and their environment. In fact, they record habits such as sleeping, exercising, third persons entering in the house, appointments. Communications may be continuously recorded. Moreover, by connecting with medical devices, they can store medical data. On one hand, this represents a very powerful tool to collect information about the single subject (precision medicine, about disease (thus eventually finding

    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.

    This paper addresses the mutual visibility problem for a set of semi-synchronous, opaque robots occupying distinct positions in the Euclidean plane. Since robots are opaque, if three robots lie on a line, the middle robot obstructs the visions of the two other robots. The mutual visibility problem asks the robots to coordinate their movements to form a configuration, within finite time and without collision, in which no three robots are collinear. Robots are endowed with a constant bits of pe...

  5. Swarm robotics and minimalism

    Sharkey, Amanda J. C.

    2007-09-01

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

  6. Multi-robot caravanning

    Denny, Jory

    2013-11-01

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

    It 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...

    Parekattil, Sijo J; Gudeloglu, Ahmet

    2013-01-01

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

    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.

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

    Recently, boron neutron capture therapy (BNCT) has merged as an interesting option for the treatment of some kind of tumors where established therapies show no success. A molecular boronated species, enriched in {sup 10}B is administrated to the subject; it localizes in malignant tissues depending the kind of tumor and localization. Therefore, a very important fact in BNCT research is the detection of boron at trace or ultra trace levels precisely and accurately. This is extremely necessary as boronated species do localize in tumoral tissue and also localize in liver, kidney, spleen, skin, membranes. By this way, before testing a boronated species, it is mandatory to determine its biodistribution in a statistically meaning population, that is related with managing of a great number of samples. In the other hand, it is necessary to exactly predict when to begin the irradiation and to determine the magnitude of radiation to obtain the desired radiological dose for a specified mean boron concentration. This involves the determination of boron in whole blood, which is related with boron concentration in the tumor object of treatment. The methodology selected for the analysis of boron in whole blood and tissues must join certain characteristics: it must not be dependant of the chemical form of boron, it has to be fast and capable to determine boron accurately and precisely in a wide range of concentrations. The design and validation of experimental models involving animals in BNCT studies and the determination of boron in blood of animals and subjects upon treatment require reliable analytical procedures to determine boron quantitatively in those biologic materials. Inductively coupled plasma-atomic emission spectrometry (ICP-AES) using pneumatic nebulization is one of the most promising methods for boron analysis, but the sample must be liquid and have low solid concentration. In our case, biological tissues and blood, it is mandatory to mineralize and/or dilute samples. Digestion in open vessels may conduct to analyte losses due to vaporization of volatile compounds. The mineralization in closed vessels, at high pressure, does not allow this losses and increase the efficiency to destroy organic mater due to the combined action of pressure and temperature. This paper describes the development of analytical methodologies to determine boron at trace and ultra trace levels. (author)

    We have initially published our experience with the robotic transthoracic esophagectomy in 32 patients from a single institute. The present paper is the extension of our experience with robotic system and to best of our knowledge this represents the largest series of robotic transthoracic esophagectomy worldwide. The objective of this study was to investigate the feasibility of the robotic transthoracic esophagectomy for esophageal cancer in a series of patients from a single institute. A retrospective review of medical records was conducted for 83 esophageal cancer patients who underwent robotic esophagectomy at our institute from December 2009 to December 2012. All patients underwent a thorough clinical examination and pre-operative investigations. All patients underwent robotic esophageal mobilization. En-bloc dissection with lymphadenectomy was performed in all cases with preservation of Azygous vein. Relevant data were gathered from medical records. The study population comprised of 50 men and 33 women with mean age of 59.18 years. The mean operative time was 204.94 mins (range 180 to 300). The mean blood loss was 86.75 ml (range 50 to 200). The mean number of lymph node yield was 18. 36 (range 13 to 24). None of the patient required conversion. The mean ICU stay and hospital stay was 1 day (range 1 to 3) and 10.37 days (range 10 to 13), respectively. A total of 16 (19.28%) complication were reported in these patents. Commonly reported complication included dysphagia, pleural effusion and anastomotic leak. No treatment related mortality was observed. After a median follow-up period of 10 months, 66 patients (79.52%) survived with disease free stage. We found robot-assisted thoracoscopic esophagectomy feasible in cases of esophageal cancer. The procedure allowed precise en-bloc dissection with lymphadenectomy in mediastinum with reduced operative time, blood loss and complications.

    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.

However, it has become increasingly apparent that social and interactive skills are necessary requirements in many application areas and contexts where robots need to interact and collaborate with other robots or humans. Research on human-robot interaction (HRI) poses many challenges regarding the nature of interactivity and 'social behaviour' in robot and humans. The first part of this paper addresses dimensions of HRI, discussing requirements on social skills for robots and introducing the conceptual space of HRI studies. In order to illustrate these concepts, two examples of HRI research are presented. First, research is surveyed which investigates the development of a cognitive robot companion. The aim of this work is to develop social rules for robot behaviour (a 'robotiquette') that is comfortable and acceptable to humans. Second, robots are discussed as possible educational or therapeutic toys for children with autism. The concept of interactive emergence in human-child interactions is highlighted. Different types of play among children are discussed in the light of their potential investigation in human-robot experiments. The paper concludes by examining different paradigms regarding 'social relationships' of robots and people interacting with them.

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

    The purpose of this action research project was to investigate the impact a students' participation in educational robotics has on his or her performance in the STEM subjects. This study attempted to utilize educational robotics as a method for increasing student achievement and engagement in STEM subjects. Over the course of 12 weeks, an after-school robotics program was offered to students. Guided by the standards and principles of VEX IQ, a leading resource in educational robotics, students worked in collaboration on creating a design for their robot, building and testing their robot, and competing in the VEX IQ Crossover Challenge. Student data was gathered through a pre-participation survey, observations from the work they performed in robotics club, their performance in STEM subject classes, and the analysis of their end-of-the-year report card. Results suggest that the students who participate in robotics club experienced a positive impact on their performance in STEM subject classes.

    Optoelectric inspection may find applications in robotic system. In micro robotic system, smaller optoelectric inspection system is preferred. However, as miniaturizing the size of the robot, the number of the optoelectric detector becomes lack. And lack of the information makes the micro robot difficult to acquire its status. In our lab, a micro line trace robot has been designed, which autonomous acts based on its optoelectric detection. It has been programmed to follow a black line printed on the white colored ground. Besides the optoelectric inspection, logical algorithm in the microprocessor is also important. In this paper, we propose a simply logical algorithm to realize robot's intelligence. The robot's intelligence is based on a AT89C2051 microcontroller which controls its movement. The technical details of the micro robot are as follow: dimension: 30mm*25mm*35*mm; velocity: 60mm/s.

  18. 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.

  19. Salvage robotic radical prostatectomy

    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.

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

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

    An intelligent tracker capable of robotic applications requiring guidance and control of platforms, robotic arms, and end effectors has been developed. This packaged system capable of supervised autonomous robotic functions is partitioned into a multiple processor/parallel processing configuration. The system currently interfaces to cameras but has the capability to also use three-dimensional inputs from scanning laser rangers. The inputs are fed into an image processing and tracking section where the camera inputs are conditioned for the multiple tracker algorithms. An executive section monitors the image processing and tracker outputs and performs all the control and decision processes. The present architecture of the system is presented with discussion of its evolutionary growth for space applications. An autonomous rendezvous demonstration of this system was performed last year. More realistic demonstrations in planning are discussed.

    An ultrasonic decontamination robot removes radioactive contamination from the internal surface of the inlet and outlet headers, divider plate, tube sheet, and lower portions of tubes of a nuclear power plant steam generator. A programmable microprocessor controller guides the movement of a robotic arm mounted in the header manway. An ultrasonic transducer having a solvent delivery subsystem through which ultrasonic action is achieved is moved by the arm over the surfaces. A solvent recovery suction tube is positioned within the header to remove solvent therefrom while avoiding interference with the main robotic arm. The solvent composition, temperature, pressure, viscosity, and purity are controlled to optimize the ultrasonic scrubbing action. The ultrasonic transducer is controlled at a power density, frequency, and on-off mode cycle such as to optimize scrubbing action within the range of transducer-to-surface distance and solvent layer thickness selected for the particular conditions encountered. Both solvent and transducer control actions are optimized by the programmable microprocessor. (author)

    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.

The proposal is based on take advantage of the potential that these platforms currently have for solving the rigid body dynamics, which easily allows modeling the mechanical aspects of the manipulator. On the other hand, the possibility offered by these platforms of incorporate programming code in conventional languages allows to modeling the dynamic behavior of real physical systems, such as sensors and actuators, which allows implementing the development of the instrumentation and control stage of an industrial robot in the same way as a real one. Using these platforms allows the modeling from the bases of any manipulator robot. The modeling of a reconfigurable parallel robot is presented as a case study.

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

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

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

    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...

    For the conventional high-speed welding robot, the welding current was controlled mainly for reducing the spatters during short circuits and for stabilizing the beads by the periodic short circuits. However, an increase of deposition amount in response to the speed is required for the high-speed welding. Large-current low-spatter welding current region control was added. Units were integrated into a package by which the arc length is kept in short without dispersion of arc length for welding without defects such as undercut and unequal beads. In automobile industry, use of aluminum parts is extended for the light weight. The welding is very difficult, and automation is not so progressing in spite of the poor environment. Buckling of welding wire is easy to occur, and supply of wire is obstructed by the deposition of chipped powders on the torch cable, which stay within the contact chip resulting in the deposition. Dislocation of locus is easy to occur at the corner of rectangular pipe during the welding. By improving these troubles, an aluminum MIG welding robot package has been developed. 13 figs.

    Robotic assisted transanal polipectomy may have advantages compared with the conventional transanal minimally invasive surgery technique. We evaluate the safety, feasibility and advantages of this technique. Between February 2014 and October 2015, 9patients underwent robotic transanal polypectomy. We performed a retrospective study in which we analyse prospectively collected data regarding patient and tumor characteristics, perioperative outcomes, pathological report, morbidity and mortality. A total of 5 male and 4 female patients underwent robotic TAMIS. Lesions were 6,22cm from the anal verge. Mean size was 15,8cm 2 . All procedures were performed in the lithotomy position. Closure of the defect was performed in all cases. Mean blood loss was 39,8ml. Mean operative time was 71,9min. No severe postoperative complications or readmissions occured. Median hospital stay was 2,5 days. Robotic TAMIS is useful to treat complex rectal lesions. Our transanal platform allowed a wider range of movements of the robotic arms and to perform all procedures in the lithotomy position. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U.

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

    The Robotics Technology Development Program (RTDP) is a ''needs-driven'' effort. A lengthy series of presentations and discussions at DOE sites considered critical to DOE's Environmental Restoration and Waste Management (EM) Programs resulted in a clear understanding of needed robotics applications toward resolving definitive problems at the sites. A detailed analysis of the Tank Waste Retrieval (TWR), Contaminant Analysis Automation (CAA), Mixed Waste Operations (MWO), and Decontamination ampersand Dismantlement (D ampersand D). The RTDP Group realized that much of the technology development was common (Cross Cutting-CC) to each of these robotics application areas, for example, computer control and sensor interface protocols. Further, the OTD approach to the Research, Development, Demonstration, Testing, and Evaluation (RDDT ampersand E) process urged an additional organizational break-out between short-term (1--3 years) and long-term (3--5 years) efforts (Advanced Technology-AT). The RDTP is thus organized around these application areas -- TWR, CAA, MWO, D ampersand D and CC ampersand AT -- with the first four developing short-term applied robotics. An RTDP Five-Year Plan was developed for organizing the Program to meet the needs in these application areas

    Godfrey, Juleon Taylor

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

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

    In case of robot vision, most important problem is the processing speed of acquiring and analyzing images are less than the speed of execution of the robot. In an actual robot color vision system, it is considered that the system should be processed at real time. We guessed this problem might be solved using by the bicolor analysis technique. We have been testing a system which we hope will give us insight to the properties of bicolor vision. The experiment is used the red channel of a color CCD camera and an image from a monochromatic camera to duplicate McCann's theory. To mix the two signals together, the mono image is copied into each of the red, green and blue memory banks of the image processing board and then added the red image to the red bank. On the contrary, pure color images, red, green and blue components are obtained from the original bicolor images in the novel color system after the scaling factor is added to each RGB image. Our search for a bicolor robot vision system was entirely successful.

    1985-01-01

    A Space Robot Simulator Vehicle (SRSV) was constructed to model a free-flying robot capable of doing construction, manipulation and repair work in space. The SRSV is intended as a test bed for development of dynamic and static control methods for space robots. The vehicle is built around a two-foot-diameter air-cushion vehicle that carries batteries, power supplies, gas tanks, computer, reaction jets and radio equipment. It is fitted with one or two two-link manipulators, which may be of many possible designs, including flexible-link versions. Both the vehicle body and its first arm are nearly complete. Inverse dynamic control of the robot's manipulator has been successfully simulated using equations generated by the dynamic simulation package SDEXACT. In this mode, the position of the manipulator tip is controlled not by fixing the vehicle base through thruster operation, but by controlling the manipulator joint torques to achieve the desired tip motion, while allowing for the free motion of the vehicle base. One of the primary goals is to minimize use of the thrusters in favor of intelligent control of the manipulator. Ways to reduce the computational burden of control are described.

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

    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.

  14. 30 Years of Robotic Surgery.

    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.

    Full Text Available Robot is a device, which performs human task or behave like a human-being. It needs expertise skills and complex programming to design. For designing a fire fighter robot, many sensors and motors were used. User firstly send robot to an affected area, to get live image of the field with the help of mobile camera via Wi-Fi using IP camera application to laptop. If any signs of fire shown in image, user direct robot in that particular direction for confirmation. Fire sensor and temperature sensor detects and measures the reading, after confirmation robot sprinkle water on affected field. During extinguish process if any obstacle comes in between the prototype and the affected area the ultrasonic sensor detects the obstacle, in response the robotic arm moves to pick and place that obstacle to another location for clearing the path. Meanwhile if any poisonous gas is present, the gas sensor detects and indicates by making alarm.

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

    As robotics are becoming more integrated into the medical field, robotic training is becoming more crucial in order to overcome the lack of experienced robotic surgeons. However, there are several obstacles facing the development of robotic training programs like the high cost of training and the increased operative time during the initial period of the learning curve, which, in turn increase the operative cost. Robotic-assisted laparoscopic prostatectomy is the most commonly performed robotic surgery. Moreover, robotic surgery is becoming more popular among urologic oncologists and pediatric urologists. The need for a standardized and validated robotic training curriculum was growing along with the increased number of urologic centers and institutes adopting the robotic technology. Robotic training includes proctorship, mentorship or fellowship, telementoring, simulators and video training. In this chapter, we are going to discuss the different training methods, how to evaluate robotic skills, the available robotic training curriculum, and the future perspectives.

  1. Robot transparency, trust and utility

    Wortham, Robert H.; Theodorou, Andreas

    2017-07-01

    As robot reasoning becomes more complex, debugging becomes increasingly hard based solely on observable behaviour, even for robot designers and technical specialists. Similarly, non-specialist users have difficulty creating useful mental models of robot reasoning from observations of robot behaviour. The EPSRC Principles of Robotics mandate that our artefacts should be transparent, but what does this mean in practice, and how does transparency affect both trust and utility? We investigate this relationship in the literature and find it to be complex, particularly in nonindustrial environments where, depending on the application and purpose of the robot, transparency may have a wider range of effects on trust and utility. We outline our programme of research to support our assertion that it is nevertheless possible to create transparent agents that are emotionally engaging despite having a transparent machine nature.

  3. What makes a robot 'social'?

    Science.gov (United States)

    Jones, Raya A

    2017-08-01

    Rhetorical moves that construct humanoid robots as social agents disclose tensions at the intersection of science and technology studies (STS) and social robotics. The discourse of robotics often constructs robots that are like us (and therefore unlike dumb artefacts). In the discourse of STS, descriptions of how people assimilate robots into their activities are presented directly or indirectly against the backdrop of actor-network theory, which prompts attributing agency to mundane artefacts. In contradistinction to both social robotics and STS, it is suggested here that to view a capacity to partake in dialogical action (to have a 'voice') is necessary for regarding an artefact as authentically social. The theme is explored partly through a critical reinterpretation of an episode that Morana Alač reported and analysed towards demonstrating her bodies-in-interaction concept. This paper turns to 'body' with particular reference to Gibsonian affordances theory so as to identify the level of analysis at which dialogicality enters social interactions.

    A continuing need exists for automatic or remote-controlled machines or robots which can perform inspection and maintenance tasks in nuclear power plants. Toshiba has developed several types of monofunctional and multi- functional robots for such purposes over the past 20 years, some of which have already been used in actual plants. This paper describes new multifunctional robots for inspection and maintenance. An inspection robot has been applied in an actual plant for two years for performance testing. Maintenance robots for grinding tasks have also been developed, which can be easily teleoperated by the operator using automatic control. These new robots are expected to be applied to actual inspection and maintenance work in nuclear power plants. (author)

    This paper addresses the advent of mobile robotic systems into the earth sciences and environmental studies. It presents issues surrounding the rationale for employing stationary and mobile robots to assist in waste chemical site remediation and cleanup activities, missions that could be conducted, and the current availability status for these devices. This rationale is an extension of that being promoted by the US Department of Energy (DOE) to assist in resolving environmental restoration and waste management (ER and WM) issues associated with several DOE national laboratories, facilities, and other sites. DOE has also committed to restore the environment surrounding the existing storage facilities and sites to a safe state. Technologies that are expected to play a major role in these activities are stationary and mobile robotic devices, and in particular, mobile robots. Specific topics discussed in this article include: introduction to robotics: motivations for considering robots in HWM: incorporation of robotics into HWM methods--this subsection includes a rationale for performing a ''screening test'' to determine the advantages of using a robot; safety and performance factors; illustrations for robots in action and current and future trends

    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.

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

    A decade ago, the United States was creating about 75% of the world's technology. Today, it is something like 50%. A decade from now, the figure could be down to 30%. The deteriorating condition of the U.S. competitive position in the world marketplace has become painfully evident to our government, the business community, and to labor. As with the energy crisis of several years ago, there has been a rude awakening to the critical need for a turnaround in our efforts to improve both productivity and quality. Industrial robots represent one of the most promising approaches to achieving both objectives. Today's top buzzword is, indeed, ''robot.'' The attention is well deserved. These versatile forms of flexible automation can improve productivity and quality through their consistent performance under the most difficult of working conditions. They are building an excellent track record in terms of dependability and uptime. The robot population in the U.S. now stands at around 7000, with sales growing at an annual rate of about 30%. By 1990, the total number of these machines on the plant floor could reach 100,000

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

    2012-01-01

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

    1990-01-01

    Remote manual operations in radiation environments are typically performed very slowly. Sensor-based computer-controlled robots hold great promise for increasing the speed and safety of remote operations; however, the programming of robotic systems has proven to be expensive and difficult. Generalized approaches to robot programming that reuse available software modules and employ programming languages which are independent of the specific robotic and sensory devices being used are needed to speed software development and increase overall system reliability. This paper discusses the robot independent programming environment (RIPE) developed at Sandia National Laboratories (SNL). The RIPE is an object-oriented approach to robot system architectures; it is a software environment that facilitates rapid design and implementation of complex robot systems for diverse applications. An architecture based on hierarchies of distributed multiprocessors provides the computing platform for a layered programming structure that models applications using software objects. These objects are designed to support model-based automated programming of robotic and machining devices, real-time sensor-based control, error handling, and robust communication

  7. Robot Wars: US Empire and geopolitics in the robotic age

    Shaw, Ian GR

    2017-01-01

    How will the robot age transform warfare? What geopolitical futures are being imagined by the US military? This article constructs a robotic futurology to examine these crucial questions. Its central concern is how robots – driven by leaps in artificial intelligence and swarming – are rewiring the spaces and logics of US empire, warfare, and geopolitics. The article begins by building a more-than-human geopolitics to de-center the role of humans in conflict and foreground a worldly understanding of robots. The article then analyzes the idea of US empire, before speculating upon how and why robots are materializing new forms of proxy war. A three-part examination of the shifting spaces of US empire then follows: (1) Swarm Wars explores the implications of miniaturized drone swarming; (2) Roboworld investigates how robots are changing US military basing strategy and producing new topological spaces of violence; and (3) The Autogenic Battle-Site reveals how autonomous robots will produce emergent, technologically event-ful sites of security and violence – revolutionizing the battlespace. The conclusion reflects on the rise of a robotic US empire and its consequences for democracy. PMID:29081605

  8. Interactive Exploration Robots: Human-Robotic Collaboration and Interactions

    2017-01-01

    For decades, NASA has employed different operational approaches for human and robotic missions. Human spaceflight missions to the Moon and in low Earth orbit have relied upon near-continuous communication with minimal time delays. During these missions, astronauts and mission control communicate interactively to perform tasks and resolve problems in real-time. In contrast, deep-space robotic missions are designed for operations in the presence of significant communication delay - from tens of minutes to hours. Consequently, robotic missions typically employ meticulously scripted and validated command sequences that are intermittently uplinked to the robot for independent execution over long periods. Over the next few years, however, we will see increasing use of robots that blend these two operational approaches. These interactive exploration robots will be remotely operated by humans on Earth or from a spacecraft. These robots will be used to support astronauts on the International Space Station (ISS), to conduct new missions to the Moon, and potentially to enable remote exploration of planetary surfaces in real-time. In this talk, I will discuss the technical challenges associated with building and operating robots in this manner, along with lessons learned from research conducted with the ISS and in the field.

    Evolutionary algorithms have previously been applied to the design of morphology and control of robots. The design space for such tasks can be very complex, which can prevent evolution from efficiently discovering fit solutions. In this article we introduce an evolutionary-developmental (evo-devo) experiment with real-world robots. It allows robots to grow their leg size to simulate ontogenetic morphological changes, and this is the first time that such an experiment has been performed in the physical world. To test diverse robot morphologies, robot legs of variable shapes were generated during the evolutionary process and autonomously built using additive fabrication. We present two cases with evo-devo experiments and one with evolution, and we hypothesize that the addition of a developmental stage can be used within robotics to improve performance. Moreover, our results show that a nonlinear system-environment interaction exists, which explains the nontrivial locomotion patterns observed. In the future, robots will be present in our daily lives, and this work introduces for the first time physical robots that evolve and grow while interacting with the environment.

  14. Madres solteras por elección: entre el “engaño” y la solidaridad

    Directory of Open Access Journals (Sweden)

    María Isabel Jociles

    2010-05-01

    Full Text Available En este artículo se analizan los discursos sobre las motivaciones que las Madres Solteras por Elección (MSPE aducen para optar, o no, por las diferentes vías de acceso a la monoparentalidad electiva que ellas mismas distinguen: la que denominan “el engaño”, esto es, la fecundación sexual planificada pero no declarada, la fecundación sexual mediante “donante conocido”, la fecundación asistida y la adopción internacional. Estos discursos, producidos tanto en entrevistas cualitativas como en otros contextos de interacción (foros de Internet, kedadas, reuniones de amigas, etc., han sido objeto de observación en el contexto de una investigación etnográfica realizada en la Comunidad de Madrid (España durante el periodo 2008-2009. Dichos discursos ponen de manifiesto, en primer lugar, que las MSPE manejan una gran variedad de concepciones acerca de la maternidad y el vínculo materno-filial. Estas condiciones fundamentan las “motivaciones”, asimismo diversas, que alegan para justificar la opción que han escogido. En segundo lugar, que su toma de decisiones está mediada por la existencia de una jerarquía socio-moral entre las distintas vías de acceso a la maternidad en solitario, cuyas posiciones más bajas están ocupadas por “el engaño” y “el donante conocido”, y la más elevada, por la adopción internacional. Se concluye subrayando la idea de que los enunciados de valor en que se basa dicha jerarquía socio-moral explican la pervivencia de la “motivación de la solidaridad” en el discurso de las MSPE adoptantes, a pesar de la deslegitimación de que es objeto por parte del conocimiento experto sobre el tema.

    The fundamental technique of performing percutaneous cardiovascular (CV) interventions has remained unchanged and requires operators to wear heavy lead aprons to minimize exposure to ionizing radiation. Robotic technology is now being utilized in interventional cardiology partially as a direct result of the increasing appreciation of the long-term occupational hazards of the field. This review was undertaken to report the clinical outcomes of percutaneous robotic coronary and peripheral vascular interventions. Areas covered: A systematic literature review of percutaneous robotic CV interventions was undertaken. The safety and feasibility of percutaneous robotically-assisted CV interventions has been validated in simple to complex coronary disease, and iliofemoral disease. Studies have shown that robotically-assisted PCI significantly reduces operator exposure to harmful ionizing radiation without compromising procedural success or clinical efficacy. In addition to the operator benefits, robotically-assisted intervention has the potential for patient advantages by allowing more accurate lesion length measurement, precise stent placement and lower patient radiation exposure. However, further investigation is required to fully elucidate these potential benefits. Expert commentary: Incremental improvement in robotic technology and telecommunications would enable treatment of an even broader patient population, and potentially provide remote robotic PCI.

    1982-01-01

    A robot has been incorporated in a clean room operation in which vacuum tube parts are cleaned just prior to final assembly with a 60 lb/in 2 blast of argon gas. The robot is programmed to pick up the parts, manipulate/rotate them as necessary in the jet pattern and deposit them in a tray precleaned by the robot. A carefully studied implementation plan was followed in the procurement, installation, modification and programming of the robot facility. An unusual configuration of one tube part required a unique gripper design. A study indicated that the tube parts processed by the robot are 12% cleaner than those manually cleaned by an experienced operator

  7. [Robot-assisted pancreatic resection].

    2017-06-01

    Although robot-assisted pancreatic surgery has been considered critically in the past, it is nowadays an established standard technique in some centers, for distal pancreatectomy and pancreatic head resection. Compared with the laparoscopic approach, the use of robot-assisted surgery seems to be advantageous for acquiring the skills for pancreatic, bile duct and vascular anastomoses during pancreatic head resection and total pancreatectomy. On the other hand, the use of the robot is associated with increased costs and only highly effective and professional robotic programs in centers for pancreatic surgery will achieve top surgical and oncological quality, acceptable operation times and a reduction in duration of hospital stay. Moreover, new technologies, such as intraoperative fluorescence guidance and augmented reality will define additional indications for robot-assisted pancreatic surgery.

    Krause, Jens; Winfield, Alan F T; Deneubourg, Jean-Louis

    2011-07-01

    Interactive robots have the potential to revolutionise the study of social behaviour because they provide several methodological advances. In interactions with live animals, the behaviour of robots can be standardised, morphology and behaviour can be decoupled (so that different morphologies and behavioural strategies can be combined), behaviour can be manipulated in complex interaction sequences and models of behaviour can be embodied by the robot and thereby be tested. Furthermore, robots can be used as demonstrators in experiments on social learning. As we discuss here, the opportunities that robots create for new experimental approaches have far-reaching consequences for research in fields such as mate choice, cooperation, social learning, personality studies and collective behaviour.

    During the last decade the role of minimally invasive surgery has been increased, especially with the introduction of the robotic system in the surgical field. The most important advantages of robotic system are represented by the wristed instrumentation and the depth perception, which can overcome the limitation of traditional thoracoscopy. However, some data still exist in literature with regard to robotic lobectomy. The majority of papers are focused on its safety and feasibility, but further studies with long follow-ups are necessary in order to assess the oncologic outcomes. We reviewed the literature on robotic lobectomy, with the main aim to better define the role of robotic system in the clinical practice. PMID:25207216

  13. Robotic refueling machine

    International Nuclear Information System (INIS)

    Challberg, R.C.; Jones, C.R.

    1996-01-01

    One of the longest critical path operations performed during the outage is removing and replacing the fuel. A design is currently under development for a refueling machine which would allow faster, fully automated operation and would also allow the handling of two fuel assemblies at the same time. This design is different from current designs, (a) because of its lighter weight, making increased acceleration and speed possible, (b) because of its control system which makes locating the fuel assembly more dependable and faster, and (c) because of its dual handling system allowing simultaneous fuel movements. The new design uses two robotic arms to span a designated area of the vessel and the fuel storage area. Attached to the end of each robotic arm is a lightweight telescoping mast with a pendant attached to the end of each mast. The pendant acts as the base unit, allowing attachment of any number of end effectors depending on the servicing or inspection operation. Housed within the pendant are two television cameras used for the positioning control system. The control system is adapted from the robotics field using the technology known as machine vision, which provides both object and character recognition techniques to enable relative position control rather than absolute position control as in past designs. The pendant also contains thrusters that are used for fast, short distance, precise positioning. The new refueling machine system design is capable of a complete off load and reload of an 872 element core in about 5.3 days compared to 13 days for a conventional system

  15. Robot Control Overview: An Industrial Perspective

    Directory of Open Access Journals (Sweden)

    T. Brogårdh

    2009-07-01

    Full Text Available One key competence for robot manufacturers is robot control, defined as all the technologies needed to control the electromechanical system of an industrial robot. By means of modeling, identification, optimization, and model-based control it is possible to reduce robot cost, increase robot performance, and solve requirements from new automation concepts and new application processes. Model-based control, including kinematics error compensation, optimal servo reference- and feed-forward generation, and servo design, tuning, and scheduling, has meant a breakthrough for the use of robots in industry. Relying on this breakthrough, new automation concepts such as high performance multi robot collaboration and human robot collaboration can be introduced. Robot manufacturers can build robots with more compliant components and mechanical structures without loosing performance and robots can be used also in applications with very high performance requirements, e.g., in assembly, machining, and laser cutting. In the future it is expected that the importance of sensor control will increase, both with respect to sensors in the robot structure to increase the control performance of the robot itself and sensors outside the robot related to the applications and the automation systems. In this connection sensor fusion and learning functionalities will be needed together with the robot control for easy and intuitive installation, programming, and maintenance of industrial robots.
