Perception of Safety Zone around an Industrial Robot

Abstract

Laboratory experiments were performed to investigate human perception of safe zone around an industrial robot. It was shown that an angle of approach toward the robot, the speed of robot motions and exposure to a simulated accident significantly affected the student subjects perception of the safe area around the MH33 robot. On the average, across all approach angles, the subjects selected distances of 49.2 and 70.0 cm from the robot's working envelope, for the accident and non-accident group, respectively.
