In this study, we develope a wheel chair robot system based on a electric wheel chair. Line trace system and visible light communication system are attached to the electric wheel chair to improve its user-friendliness. Line trace system is a simple and reliable control method. It is robust when its wheels slip, because it uses traveling rail. Visible light communication is a communication technology which using visible light blinking. In this system, LED illumination lamp is used to send data by high frequency blinking. And the blinking frequency is so high that human can not recognize the blinking, and it can do illuminate and send data simultaneously. Visible light communication system is used to get current robot position by communicating with landmark (i.e., LED illumination lump). The wheel chair robot system can travel to the destination automatically by selecting the route with these system.
