提出了衡量并联机器人操作精确程度的指标———误差敏感系数 ,并给出了其在工作空间中的分布情况 ,这样不需知道每一结构参数的制造误差及输入参数的误差 ,就可以了解机器人在工作空间中哪些区域工作时操作精度高 .
The paper puts forward an index of measuring the precision of parallel manipulators --- error sensitivity coefficient and gives its distribution in work space so as to know the manufacturing error of each structural parameter and the error of input parameters Robot in the work space in which areas work high precision.
