In human-robot collaborative operation applications, maintaining protective separation distance during robot operation is a safety requirement based on the associated safety standards ISO 10218 and ISO/TS 15066. In the study, we implement our proposal of potential runaway space in task space which was originally proposed by our research group on a vertical articulated robot and evaluate the distance from the robot end effector to the envelope of an additional potential runaway space. The purpose of this study is to consider the safety of workers when a robot runaway, which has not been discussed so far. As a result, the runaway distance of the robot varies depending on the direction, and the additional term to protective separation distance is sometimes too large to ignore. By using the results, optimal placement of robot and worker considered runaway of robot was possible, and the importance of adding runaway elements to protective separation distance was also shown.
