1P2-B02 Study of the front-wheel-drive type electric wheelchair for disabled children : A collision avoidance system by ultrasonic sensors(Welfare Robotics and Mechatronics (3))

Abstract

The child who had a handicap in the motor function is difficult to perform autonomous mobile. Motor dysfunction disturbs movement, and also, it becomes a disturbance for the mental development. In this study, we produce the electric wheelchair in order that a child with motor dysfunction can move independently. We aim that the disorder in development of handicapped children is restrained by actively approaching to the ambient environment and by getting various experiences. The collision avoidance system is needed, in order that a child operates it safely. This study builds the collision avoidance system which uses stop and avoidance properly by using ultrasonic sensors.
