PROBLEM TO BE SOLVED: To record the state of an excessive load and look into the cause thereof when the excessive load is applied to a robot, and to issue a warning to a person going into mischief in the case of the mischief. SOLUTION: The system judges whether or not motors that drive movable arms 3, traveling sections 1 or the like become overloaded while the robot is allowed to perform a normal operation. If these motors become overloaded, current of overloaded motors is blocked. Subsequently, a camera 5 takes pictures of the ambient conditions, the robot is stopped, an operator in charge is informed of the situations. The images taken by the camera are stored in the robot or are transferred to a server through a radio LAN and are stored there. The conditions that the robot becomes overloaded can be confirmed by these image, whether or not a trouble is caused by mischief by a person, a collision with an obstacle or a mechanical fault can be analyzed. In addition, a warning voice can be also issued to a person going into mischief by allowing the camera to be oriented to the direction to which an excessive load is applied.
