General evaluation method of safety for human-care robots

摘要

This paper proposes the world's first general evaluation method of safety for human-care and medical robots. The safety values chosen are impact force and impact stress. The danger index and safety index are defined to make quantitative evaluation of the effectiveness of each safety strategy. Moreover, this proposed method enables us to know the contribution of each safety strategy to the overall safety performance of human-care robots. As a result, design optimization of safe robots is discussed successfully.
