中文摘要：

文章基于实验室打乒乓球的实际情况，对目标点即击球点姿态进行了降维处理，并在此基础上，成功地将广义加权最小二乘法应用到移动机械手上。在应用过程中，对阻尼系数进行了研究，并在最后，对这种方法进行了仿真和分析。

英文摘要：

The paper is based on the actual situation of playing ping-pang in our laboratory, and reduces the posture dimensions of the target point, that is the hitting point. And on this basis the general-weighted least-norm method is successfully applied in mobile manipulator. During application, the damping coefficient is studied, and then the method is analyzed and simulated.
