Applying vision-based pose estimation in a telerehabilitation application

In this paper, an augmented reality mirror application using vision-based human pose detection based on vision-based pose detection called ExerCam is presented. ExerCam does not need any special controllers or sensors for its operation, as it works with a simple RGB camera (webcam type), which makes the application totally accessible and low cost. This application also has a system for managing patients, tasks and games via the web, with which a therapist can manage their patients in a ubiquitous and totally remote way. As a final conclusion of the article, it can be inferred that the application developed is viable as a telerehabilitation tool, as it has the resource of a task mode for the calculation of the range of motion (ROM) and, on the other hand, a game mode to encourage patients to improve their performance during the therapy, with positive results obtained in this aspect.This work has been partially supported by the Spanish State Research Agency, under project grant AriSe2: FINe (Ref.

An implemetation of a teleoperated robot control architecture on a PLC and field-bus based plarform

Teleoperated robots are used to perform hazardous tasks that human operators cannot carry out. The purpose of this paper is to present a new architecture (ACROSET) for the development of these systems that takes into account the current advances in robotic architectures while adopting the component-oriented approach. ACROSET provides a common framework for developing this kind of robotized systems and for integrating intelligent components. The architecture is currently being used, tested and improved in the development of a family of robots, teleoperated cranes and vehicles which perform environmentally friendly cleaning of ship-hull surfaces (the EFTCoR project). This paper summarises the features of this project and describes the implementation of ACROSET on a hardware platform based on a PLC (Programmed Logic Controller) SIEMENS SIMATIC S7-300 and the Field-Bus PROFIBUS DP

MDE para el desarrollo de redes de sensores inalámbricas siguiendo un enfoque de líneas de producto

Las redes de sensores inalámbricas constituyen una tecnología de creciente interés para la adquisición de datos del entorno. El desarrollo de aplicaciones basadas en dicha tecnología sigue un proceso tradicional excesivamente dependiente de la infraestructura empleada para su implementación, limitando en consecuencia la reutilización de los recursos desarrollados para aplicaciones similares. Un enfoque de Líneas de Producto permite mejorar dicha reutilización, sin embargo adolece de falta de automatización. La combinación de este enfoque con la ingeniería dirigida por modelos permite la obtención de un método de desarrollo de aplicaciones en el dominio referido que combina reuso y automatización tal y como se muestra en este trabajo.La CICYT (TIC2006-15175-C05-02) y la Fundación Séneca (02998-PI-05)

Automatic ada code generation using a model-driven engineering approach

Currently, Model-Driven Engineering (MDE) is considered one of the most promising approaches for software development. In this paper, a simple but complete example based on state-machines will be used to demonstrate the benefits of this approach. After defining a modelling language (meta-model) for state-machines, a graphical tool will be presented which is aimed at easing the description and validation of state-machine models. These models will then be used as inputs for another tool which will automatically generate the corresponding Ada code, including a simulation program to test the correctness and performance of the implemented application.Proyecto MEDWSA (TIN2006-15175-C05-02)de CICYT y PMPDI-UPCT-2006 programa de la Universidad Politécnica de Cartagena

Using artificial vision for measuring the range of motion

Measurement of joint range of motion is a common measure in the functional evaluation of a patient. This clinical measurement is performed through the use of mechanical goniometry, currently presenting various problems mainly of a human nature. This article introduces ROMCam, an alternative system for measuring joint range of motion, based on estimating the human pose in 2D. For this, use is made of artificial vision libraries and the use of an RGB webcam type camera. The results obtained corroborate the validity of the use of ROMCam as a low cost, accessible tool that can even be used as a resource in telerehabilitation treatments.Este trabajo ha sido financiado por el proyecto MINECO/FEDER con identificador TEC2016-76465-C2-1-R (AIM) y por el “Research Program for Groups of Scientific Excellence in the Region of Murcia" de la Fundación Seneca (Agency for Science and Technology in the Region of Murcia – 19895/GERM/15), España

Una familia de robots para la limpieza de cascos de buques

Actualmente, la mayoría de las operaciones de reparación que se llevan a cabo en astilleros no están automatizadas. Un ejemplo es la limpieza de cascos de buques. Este trabajo describe una solución: el sistema EFTCoR. Se trata de un conjunto de robots cuya misión es la realización de diferentes operaciones de mantenimiento en los cascos de buques como granallado, pintura, etc. respetando el medio ambiente. Para ello, se combinan técnicas de diferentes disciplinas con la experiencia en el desarrollo de sistemas teleoperados.Los trabajos aquí presentados han sido desarrollados dentro del V Programa Marco (GROWTH G3RD-CT-00794), y parcialmente financiados por el Ministerio de Ciencia y Tecnología (CICYT DPI2002-11583-EEscuela Técnica Superior de Ingeniería de Telecomunicació

Simulador electromagnético de estructuras mixtas conductoras de hilo grueso y superficies planas

This paper presents a recently developed electromagnetic simulator which overcomes some of the traditional limitations of commercial software packages that analyze wire antennas combined with surface patches. A full Galerkin approach of the Method of Moments using subdomain triangle functions is employed to solve the frequency domain Electric Field Integral Equation (EFIE) for wire conducting structures. The full kernel of the EFIE is numerically computed using a suitable integration scheme. By doing so, it is possible to properly analyze moderately thick wire antennas. The analysis of the flattened surface patches is performed using rooftop basis and testing functions defined in triangular or rectangular cells. The junction of the wire and surface patches is modeled by using a new attachment mode which allows the wire to be placed everywhere inside the mesh cells. The new attachment mode has shown to be specially well suited for working in conjunction with rooftop basis functions.Los autores quieren agradecer la financiación recibida para la realización de este trabajo por parte de IZAR-CARENAS S.A.

Redes de sensores y actuadores (WSAN) en domótica

La domótica, definida como la automatización de viviendas y edificios, es uno de los campos más atractivos para la aplicación de las redes de sensores inalámbricas, siendo todavía un área de estudio poco desarrollada. El presente artículo recoge nuestras primeras experiencias en la integración de estas tecnologías. Para ello se ha realizado una maqueta de una vivienda unifamiliar de tamaño medio, y se han implementado un conjunto de actuadores y sensores domóticos inalámbricos basándonos en la tecnología actual disponible para el desarrollo de redes de sensores.Fundación Séneca de la Región de Murcia y a la CICYT del Ministerio de Educación y Ciencia de Españ
