Electronic control for a wheel-chair guided by oral commands and ultrasonic and infrared sensors

摘要

This paper describes a wheelchair for physically disable people. In this wheelchair, a dependent-user recognition voice system and ultrasonic and infrared sensor systems have been integrated. In this way, the wheelchair can be driven whit oral commands and with the possibility of obstacle avoidance and downstairs or hole detection. The wheelchair allows autonomous driving (for example following walls). This project has been develoed in the Electronic Department of the Alcala University and it has been financed by the ONCE Foundation.
