In this paper, a path planning method based on GA is presented. Firstly, the model of the space robot is built to display the mapping of the end velocity and the joint velocity. Then the optimal algorithm based on genetic algorithm is presented to search the optimal solution which minimizes the disturbance of base attitude in the feasible solution space. Finally, an illustrative example is used to verify the feasibility of the algorithm.

基于GA研究机械臂运动对基座的姿态扰动问题，首先，建立空间机器人的运动学模型及空间机器人末端与关节速度之间的映射关系；接着，应用GA作为最优化算法，在空间机器人可行解空间中，寻找最优解得到最优路径，以达到对基座姿态干扰最小的目的；最后，通过数值仿真实验验证算法的实用性。
