The system is mainly composed of a PC module, a Bluetooth receiving and transmitting module, a single chip microcomputer module, a CAN bus module, a motion controller module, an optoelectronic isolation module and a joint motor driving chip module. The motion control system is good in real-time performance high in precision and low in economic cost, cost can be reduced, and besides a doctor can easily perform a surgery more precisely, and high reliability of the surgery is guaranteed. Because a slave hand of the minimally invasive robot is generally composed of multiple joints, if motion of all the joints can not be coordinated effectively, major secondary trauma can be generated for a patient, and even life safety of the patient is threatened. Therefore, meaning of research on the motion control system of the minimally invasive surgery robot is very significant.
