摘　　要：三自由度测量臂的测量对象为沿X、Y、Z三个坐标轴的平动,即仅对运动部件进行位置跟踪与测量。测量臂是通过安装在各关节上的传感器来测量各关节的相对运动,从而间接实现对末端执行器的位置测量。The measured object of the three degree-of-freedom measurement mechanism is moving along X, Y, Z three coor- dinate axis. That is only to trace and measure the position of the motion part. The measurement mechanism measures the relative motion of each joint through the sensor installing on each joint. So the position measurement of the end execute cell can be realized indirectly.
