Remote control of electric wheelchair

Abstract

This paper describes modifications and completion of the control system of electric wheelchair in order to serve as a platform for remote-controlled mobile robot. The main task was to provide remote control of this mobile robot, because the existing control system works only with a wired controller. Due to the unavailability of appropriate documentation, it was necessary to analyze the original control system and to determine the possibility of its connection to a superior control system on the operator’s station. It was also needed to design and make an electronic module, which would implement the found solution. Through this module it is possible to send movement commands to the robot chassis via wireless links and thus to ensure the remote control at distance of up to several kilometers.
