A new type of laborsaving electric wheelchair robot system for inside building use was developed. The electric wheelchair robot system has following three functions. Those are automatic movement, position detector, and fail-safe device. Not only patient but also carers can command this electric wheelchair robot by touch panel interface, and this interface is so easy to reduce their strain while operating the robot. In those 3 functions, automatic movement was already implemented by Line-Trace control with magnetic sensor system. In this study, position detector consists of laser device, CMOS camera and pattern marker sheet was developed. Users can set pattern marker sheet at any point on line trace track line easily, and the wheelchair robot system can detect it as new check point or new station point by position detector.
