Identifying Safety Conditions of Human-Robot Collision based on Skin Injury Analysis

Abstract

Over the last few years, the robotics technology has rapidly evolved in terms of the safety enhancement. With the improvement the collaborative operation between the industrial robot and the human is now an appealing viable option. As the collaboration between the human and robot becomes more frequent, the requirement for the safety of the human in the case of collision with the robot draws much more attention. From this point of view, lot of research about the collision safety of the human has been reported recently. Most of them, however, are focused on the severe collision cases of the fatal injury. Which is mainly due to the lack of the analysis data for the minor injury. In this paper, the skin injury that is defined as a minor injury is analyzed with experimental data. Based on the analysis result, the acceptable impact (collision) condition for the robot is estimated.
