摘要: 就三臂空间机器人的一臂与航天器固抓、一臂操作、第三臂作平衡协调操作的问题进行了理论研究,取得了在线动量和角动量守衡意义上的平衡操作结论。对一个在气浮平台上运动的简单的三臂空间机器人的实例进行了仿真计算,证明该方法是可行的。为三臂多关节空间机器人的平衡协调操作提供了一种实用的方法。

Abstract: The balance problem of athree-arm space robot has been discussed during its manipulation. The first arm of the space robot is used to keep connection with the spacecraft (shuttle orspace station), the second arm to balances the whole system, and the third arm to manipulate a job. The linear momentum and angular momentum equations and an optimization function have been advanced. An optimization solution of the angles and the angular velocities of those joints of the second arm (the balance arm) according to conservation of the linear momentum and angle momentum of all systemhave been gotten respectively. One example of a simple three-arm space robot onan air-bearing table has been simulated and the results simulated have been given out with two pictures.

Key words: robots, three-arm space robot, balances, manipulation
