The incident occurred when the man, a robotics company employee in his 40s, was inspecting the robot.
The robotic arm, confusing the man for a box of vegetables, grabbed him and pushed his body against the conveyer belt, crushing his face and chest, South Korean news agency Yonhap said.
He was sent to hospital but later died.
Usually they do. Often right on the robot depending on the size. I seen many workers refuse to lock out a device because of the extra work.
