“…In order to benefit the end users who have lost control of their upper extremities due to injury, illness or disability, a speech recognition system is designed to be one of the steering control components of the MWA [4]. The user can communicate with this type of system by giving voice command.…”

ResumoEste artigo aborda a construção de um veículo acionado por motores elétricos inspirado nos artigos (MAZO, 1995;FONSECA SOBRINHO, 2000) e que seja automatizado, ou seja, possa locomover-se dentro de qualquer ambiente sem que seja necessária a intervenção humana. O controle foi feito utilizando o software Labview, com aquisição de dados e geração de sinais de controle. O veículo possui um sistema de sensores infravermelhos que indicam a existência de um obstáculo à frente do veículo, informando que o mesmo deve parar e contorná-lo. O programa implementado é o responsável pelo comando dos motores que fazem o protótipo andar e contornar os objetos. Poder ter o controle de um veículo à distância é importante em situações nas quais seria perigoso para um ser humano. A principal vantagem deste sistema é que pode-se ter total maleabilidade para que se façam alterações no software de comando, sem que seja necessário tocar a parte física do protótipo. Pode-se concluir deste trabalho que o sistema é eficiente, sendo capaz de se movimentar em uma sala com objetos sem tocá-los. Palavras Chave: Labview, Veículo Autônomo, Motores Elétricos. AbstractThis article deals with the construction of a vehicle driven by electric motors and that is automated, that is, that can move anywhere without human intervention. The control was done using the software Labview, with data acquisition and generation of control signs. The vehicle has an infrared sensors system that indicates the existence of an obstacle ahead the vehicle, informing it that it should stop and bypass the obstacle. The program is the responsible for the engine control, making it possible for the prototype to run and bypass the objects that block its way. The possibility of remote-controlling a vehicle is very important is risky situations for human beings, for example in radioactive places. The main advantage of this system is the total flexibility for making alterations in the control software, without being necessary to touch the physical part of the prototype. The conclusion of this work is that the system is efficient and able to move in a room with objects without touching them.

“…the use of one or another of these is basically conditioned by aspects such as: the degree of autonomy that the robot should have, the environment in which it has to move, the number of sensors necessary and the final price of the system. Ultrasonic or infrared sensors (Mazo et al, 1994b;Urefia et al, 1995) have been chosen for use as external sensors in the UMIDAM. The location of the sensors in the wheelchair is shown in Fig.…”

Abstract. This paper describes a wheelchair for physically disabled people developed within the UMIDAM I Project. A dependent-user recognition voice system and ultrasonic and infrared sensor systems has been integrated in this wheelchair. In this way we have obtained a wheelchair which can be driven with using voice commands and with the possibility of avoiding obstacles and downstairs or hole detection. The wheelchair has also been developed to allow autonomous driving (for example, following walls). The project, in which two prototypes have been produced, has been carried out totally in the Electronics Department of the University of Alcalfi (Spain). It has been financed by the ONCE 2. Electronic system configuration, a sensor system, a mechanical model, control (low level control, control by voice commands), voice recognition and autonomous control are considered. The results of the experiments carried out on the two prototypes are also given.
