Abstract: The twowheel inverted mobile pendulum in lab was studied. The application of CANopen protocol in control system was introduced and analyzed. A new improved control system based on CANopen protocol was proposed and analyzed detailedly. The problem of the rapidity and veracity in control system was solved. By testing experiment, the reliability of communication, the veracity and real time feature of motion control system were verified. Experimental results on the twowheel inverted mobile pendulum indicate that the system realizes the longterm control and the function of carrying person.
