探讨了点位控制在二自由度机械臂网络远程控制中的问题，将连续轨迹控制应用到基于关节坐标空间的机器人控制系统中，分析了在远程操控环境中实现连续轨迹控制所需要满足的条件，给出了最佳合成速度的求法，并进行了实际系统的远程控制实验，在期望时间内实现了连续、平滑的运动效果，证实了在网络远程系统的控制中采用连续轨迹控制能够获得更高的精度。

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.
