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