Our developed device, named "B-GO", tows walker or wheelchair for severely disabled children to move on a voluntary basis. This paper shows outline of this device and development organization and background, and discuss the performance of this device and future problem and so on. "B-GO" was developed by working group consisting of various specialist that is mechanical and electrical engineer, physical therapist, academic researcher, industrial designer and public official. In development, the suggestions from Beppu Developmental Medicine and Habilitation Center were most key point. First prototype was used by children in there and beneficial effect was confirmed. "B-GO" was a commercial reality through addition of the attractive shape and minor improvements. This device is coupled to a walker or a wheelchair, and operated using joystick.
