Using virtual potential fields for electric wheelchair guidance
(IEEE Computer Society, 2002)
TetraNauta is an electric wheelchair guidance system intended for people with heavy motion impairments (such as persons with tetraplegia). It is specially useful when impairments also affect wheelchair steering as it is ...

TetraNauta: a intelligent wheelchair for users with very severe mobility restrictions
(IEEE Computer Society, 2002)
The TetraNauta project is a low cost, fully open steering system to allow people with heavy motor impairments to move in a known environments (hospitals, schools, home, etc.). It minimizes the steering effort, especially ...

A generalization of path following for mobile robots
(IEEE Computer Society, 1999)
Several authors have proposed some methods for applying path following in specific cases to mobile robots. When we try to extend the path following approach to the general problem several difficulties arise. We present a ...

A Two-Level Dynamic Chrono-Scheduling Algorithm
(IEEE Computer Society, 2009)
We propose a dynamic instruction scheduler that does not need any kind of wakeup logic, as all the instructions are “programmed” on issue stage to be executed in pre-calculated cycles. The scheduler is composed of two ...

SIRIUS: Improving the maneuverability of powered wheelchairs
(IEEE Computer Society, 2002)
The indoor maneuverability of powered wheelchairs may be difficult or bothersome in several circumstances. In this paper, we describe an experimental powered wheelchair named SIRIUS, developed at the University of Seville, ...

The shared control dynamic window approach for non-holonomic semi-autonomous robots
(IEEE Computer Society, 2014)
A shared control method, called Shared Control Dynamic Window Approach, is presented. It is inspired in the Dynamic Window Approach (DWA) for autonomous mobile robots. It takes user commands by means of the control interface ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...

Análisis a Bajo Nivel de Procesadores Superescalares Reales
(Universidad de Alcalá de Henares. Servicio de Publicaciones, 2000)
En esta ponencia-demo se presenta una práctica donde se analiza la influencia en el tiempo de ejecución de algunas optimizaciones sobre el código máquina para procesadores reales (familia Intel Pentium). Se propone el ...

A Real-Time Wireless Sensor Network for Wheelchair Navigation
(IEEE Computer Society, 2009)
Today, the availability of inexpensive, low power hardware including CMOS cameras and wireless devices make it possible to deploy a wireless sensor network (WSN) with nodes equipped with cameras for a variety of ...
