Development of One Hand Drive Wheelchair System : 2nd report : Evaluation of the designed hand rim

Abstract

The purpose of this research is to develop the wheelchair system for hemiplegic users. The proposed system is configured by the front wheel with active steering and hand rim for detecting user’s driving force. The user’s operational intention is distinguished by the sign and amplitude of force along the rotational axis of the hand rim. The steering angle of the front wheel is controlled by an actuator based on extracted intention from the hand rim. By proposed system, user can operate the wheelchair by using only single side hand rim. In particular, in this paper, we evaluate the designed hand rim by conducting some experiments.
