By discussing the drawbacks of a 2-dof robot arm remote control based on the point-to-point control, the continuous path control method is applied to the joint-coordinate-space-based serial robot remote control system. The condition needed to realize the continuous control is analyzed and the computation formula of the optimal synthesized velocity is given. The actual remote control experiment is implemented, and the continuous and smooth movement results are obtained within the desired time. It's verified that better accuracy in remote system can be obtained by means of continuous path control.
