Abstract—Industrial robots were operated in an independent environment and did not expose humans to direct danger. However, since the operation environment of robots such as human care and collaboration has changed recently, safety and performance of this robot are inevitably important. Therefore, in this study, we studied the care robots among the service robots that collaborate with humans collectively. First, we presented the autonomy judgment index of robots as an indicator for human risk management. In addition, we presented a method to determine the accuracy of motion through food assist robots among care robots. In order to prove this experimentally, the impact level limit was set and suggested through the collision test of the human face region.

It is thought that this result can be provided as a valid indicator for developers and robot evaluators by identifying the degree of human injury in the development of care robot in the future.
