Abstract:

Firstly, in order to assess the stability of the camera robots, a stability performance index with combination of force and position is proposed based on the determinations of the cable tensions for a camera robot. Furthermore, the stability performance index is described using the weighted average method, and meanwhile,the stability workspace is designed with the stability performance index. Secondly, a robust workspace with the external wrench is selected to compare with the stable workspace above for the camera robots. Finally, simulation results show that it is suitable to employ the stable performance to evaluate the stability of the camera robots.

Key words: cable-based parallel robots, camera robot, stability, workspace, hybrid force-position approac
