The purpose of this paper is to clarify the underlying hazards of human‐mimic human‐collaborative industrial robots.
Preliminary hazard analysis is applied to a new industrial upper‐body‐humanoid under development. The result of the analysis is summarized by Fishbone diagram analysis.
Six hazard categories involving a four‐class physical human robot interaction hazard classification are derived from the analysis.
The method of analyzing hazards presented here and the hazard theory derived from the analysis can be used in other developmental projects.
