Force reflective feedback control for intelligent wheelchairs

Abstract

A force reflective feedback control system for the operation of intelligent wheelchairs is presented. A multisensor based differential-driver intelligent wheelchair "Luoson III" has been developed to conduct the experiments. We have used a Microsoft Force Feedback Pro joystick which has the force feedback and programmable capability. The joystick not only can receive the use input but also can simulate the effects of wall, shake, constant force and reflect back to the user. We have demonstrated the success of this system through the prototype wheelchair operated in an open office environment.
