Abstract
The majority of electric wheelchair users are able to operate a joystick to control the chair, however many more quadriplegic users need some other means of controlling the wheelchair. This paper describes an electronic PWM DC drive unit designed for operation by standard joystick, ultrasonic noncontact head control, and by command from a limited speech vocabulary
