Abstract: To realize the quantitative analysis of reachability of on-orbit maintenance#br# technology, maintenance mission can be broken down by stratification first. Based on that,#br# maintenance mission can be proceeded of kinematic control. Remote-control command and#br# autonomic command are emulated through PID emulator, and are transformed into kinematic#br# performers? displacement locus curve. Then the ideal maintenance kinematic emulation locus can#br# be reached. After that, the model of the robot arm?s manufacture and control variations is built. At#br# last, the reliability and validity of maintenance emulation are increased by using virtual kinematic#br# controller to add the variations into the maintenance emulations.#br# Key words: dynamics analysis; robot arm; reachability; RecurDyn
