Transoral robotic surgery vs open surgery in head and neck cancer: a systematic review of the literature
2020
Background TORS has become one of the latest surgical alternatives in the treatment of oropharynx squamous cell carcinomas (OPSCC) and has become increasingly accepted by surgeons as a treatment option. Surgical robots were designed for various purposes, such as allowing remote telesurgery, and eliminating human factors like trembling. The study aimed to compare systematic review of the available literature in order to evaluate the safety and efficacy of Transoral Robotic Surgery (TORS) compared with open surgery. Material and Methods We performed a systematic review of the available literature in order to evaluate the safety and effectiveness of TORS compared with open surgery. We compared…
Programación de microrrobots por bloques
2016
Material docente perteneciente a los cursos y talleres de difusión llevados a cabo en la ETSE-UV dentro de los programas del Servei d'Informació i Dinamització (SeDi) de la Universitat de València (Aprén Emprén, Ciència ARA, Talleres de Secundaria, Conèixer y NauJove). En los entornos tecnológicos educativos, se viene adoptando la práctica del uso de robots como incentivo a la programación y diseño de sistemas/automatismos. Debido al atractivo que éstos suscitan en los estudiantes, se genera un clima propicio para el aprendizaje. La programación y el montaje de robots no sólo tienen su aplicación en sí mismos, sino que permiten dar una idea global del funcionamiento de sistemas que se desar…
Koncepcje dotyczące osobowości prawnej robotów -zagadnienia wybrane
2019
The purpose of this article is to present the most characteristic positions of representatives of the doctrine (both representing the common law system and continental law system) whether, and if so, how to regulate legal status of robots, which might inspire a further discussion in the matter. The reason to start a discussion regarding this topic was a resolution of the European Parliament of 16.2.2017, which included a recommendation of the Commission regarding civil law regulations connected with robotics (2015/2103(INL))
Motions with Emotions? : A Phenomenological Approach to Understanding the Simulated Aliveness of a Robot Body
2019
This article examines how the interactive capabilities of companion robots, particularly their materiality and animate movements, appeal to human users and generate an image of aliveness. Building on Husserl’s phenomenological notion of a ‘double body’ and theories of emotions as affective responses, we develop a new understanding of the robots’ simulated aliveness. Analyzing empirical findings of a field study on the use of the robot Zora in care homes for older people, we suggest that the aliveness of companion robots is the result of a combination of four aspects: 1) material ingredients, 2) morphology, 3) animate movements guided by software programs and human operators as in Wizard of …
On the Stability of the Soft Pendulum With Affine Curvature: Open-Loop, Collocated Closed-Loop, and Switching Control
2022
This letter investigates the stability properties of the soft inverted pendulum with affine curvature - a template model for nonlinear control of underactuated soft robots. We look at how changes in physical parameters affect stability and equilibrium. We give conditions under which zero dynamics corresponding to a collocated choice of the output is (locally or globally) stable or unstable. We leverage these results to design a switching controller that stabilizes a class of nonlinear equilibria of the pendulum, which can drive the system from one equilibrium to another.
La utilización de robots para mitigar la soledad en las personas mayores: estado del arte
2013
La introducción en nuestra vida diaria de las tecnologías para la comunicación e internet (ICT) en el mundo actual es un hecho equiparable a la alfabetización y la introducción de la radio en los hogares en otros momentos de la historia. Paralelo a esa introducción y al desarrollo de los sistemas de información se está produciendo el desarrollo de sistemas autónomos o robots. El objetivo de este trabajo es la realización de un estado del arte sobre el uso de los robots como medio para mejorar su actividad social o mitigar los efectos de la soledad en las personas mayores o muy mayores. Metodología: se ha revisado publicaciones indexadas en las principales bases de datos consultadas por inve…
Elementos de resolución de problemas en primeras edades escolares con Bee-bot
2018
En este trabajo se presenta un estudio exploratorio sobre elementos de resolución de problemas puestos en juego por estudiantes de primeras edades escolares mientras resuelven tareas con el robot programable Bee-bot. En dichos problemas, los estudiantes deben secuenciar las instrucciones necesarias para que el robot recorra un camino desde un punto inicial a otro final. Se pretende observar y caracterizar actuaciones de tres parejas de estudiantes con el fin de determinar recursos heurísticos y procesos de gestión desarrollados durante la resolución de los problemas. Al ser un estudio exploratorio, se han seleccionado dos parejas de estudiantes del último curso de infantil y una pareja del …
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
Emergence of technostress among employees working with physical robots
2023
Despite the growing body of literature on technostress, there is limited knowledge about the emergence of technostress among people working with physical robots. In this paper, we aim to address this research gap by exploring how technostress emerges among employees working with physical robots. The study was based on qualitative online questionnaire responses from 197 present or previous users of robots at work. Based on our data, we identified several robot-related environmental conditions that contributed to perceived work-related stress. Our findings reveal that the emergence of technostress among employees working with physical robots has distinct characteristics and that the technostr…
Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).
2020
Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…
