Conference Paper
In this work we present a software tool that permits the design of several types of controllers and the simulation of the final controlled system. This software can be used both in classical and in modern control theory subjects. The tool used to generate this graphical interface is Easy Java Simulations, which allows us to implement interactive si...
Article
Frequently, road traffic accidents are modelled as discrete and independent random and rare events, which possess a low probability of occurrence through time. Nevertheless, in order to study each accident individually it is necessary to obtain details of a number of characteristics that surround it, which may be correlated with each other. In this...

Nowadays, the design of fully autonomous mobile robots is a key discipline. Building a robust model of the unknown environment is an important ability the robot must develop. Using this model, this robot must be able to estimate its current position and to navigate to the target points. The use of omnidirectional vision sensors is usual to solve th...
Article
This study focuses on an approach to the multi-robot simultaneous localisation and mapping (SLAM) problem. The authors consider that a team of robots start the map building process from known initial poses and move through the environment observing a set of landmarks. In particular, the authors consider that the robots are equipped with vision sens...

This paper focusses on an approach to the multi-robot SLAM problem. We consider that a team of robots start the map building process from known initial poses and move through the environment observing a set of landmarks. In particular, we consider that the robots are equipped with vision sensors and are capable to compute the relative distance to n...
Chapter
In this chapter the authors approach the problem that hand-on experiments may present in engineering studies and how Internet has become a powerful tool to improve the students' motivation, interaction and degree of learning. Also, the authors address some challenges that must be taken into account in order to improve the effectiveness of the remot...
Patent
La vela electrónica de la invención tiene como característica fundamental el hecho de simular el comportamiento de una vela real, tanto en el efecto llama de la parte luminosa, como el movimiento descendente que lleva acabo la llama con el transcurso del tiempo propio del consumo de la vela. El sistema está formado por un cuerpo opaco (2) en cuya...
Patent
Se trata de un dispositivo electrónico basado en un microcontrolador que permite actuar de forma local y remota sobre electroválvulas o relés. El dispositivo electrónico está compuesto por un modulo microcontrolador conectado a un módulo de comunicaciones inalámbricas IEEE 802.15.4 capaz de transmitir tramas de datos que incorporan lecturas de dife...
Patent
Se describen un mecanismo y un módulo de posicionamiento que permite alcanzar una posición y orientación determinada del plano móvil respecto al extremo de referencia fijo (plano fijo). Este módulo mecánico puede utilizarse en aquellas aplicaciones en las que sea necesario mover o posicionar materiales, herramientas de manufactura, mantenimiento o...
Patent
El producto desarrollado e implementado se compone de un terminal inteligente que provee al usuario una interfaz de acceso (tanto desde el punto de vista visual, como a través de una pantalla táctil, o bien mediante señales acústicas), de manera que puede interaccionar con las personas en múltiples ambientes: - Como terminal de punto de venta - Co...

El objetivo de este artí?culo es encontrar un extractor de características visuales que pueda ser utilizado en un proceso de SLAM (Simultaneous Localization and Mapping). Este extractor de características consiste en la combinación de un detector que extrae puntos significativos del entorno, y un descriptor local que caracteriza dichos puntos. Este...

Full-text available
The visual information captured by omnidirectional systems is very rich and it may be very useful for a robot to create a map of an environment. This map could be composed of several panoramic images taken from different points of view in the environment, and some geometric relationships between them. To carry out any task, the robot must be able t...

In this Chapter a solution to SLAM based on a Rao-Blackwellized particle filter has been presented. This filter uses visual information extracted from cameras. We have used natural landmarks as features for the construction of the map. The method is able to build 3D maps of a particular environment using relative measurements extracted from a stere...
