Abstract: As the application of robot has been developed, mobile robot had been a very active branch of it. As an experimental platform for autonomous intelligent control, mobile robot is required more and more for its open control system. In this paper, we'll introduce the hardware system and relative software platform of the user oriented mobile robot that we'd designed by ourselves in detail and with emphasis on analyzing open software control system. It's appropriate for the system to be an open experimental platform and a robot for teaching.
