Short summary

This paper proposes a synthesis method for compliant bistable mechanism based on pole similarity transformation. The rigid components in the synthesis results can self-maintain at two specified positions assigned by the motion task, which are the two stable states of the mechanism. Even if the mechanism deviates from these positions under external forces, it can rely on its own internal forces to return to the stable-state positions.
