Abstract: It is possible to obtain an industrial robot which assures excellent reduction in maintenance. The industrial robot includes a robot body, a manipulator to control the operation of the robot body, a control device to control the manipulator, a first path disposed between the manipulator and the control device, and a second path between a commercial power source and the manipulator. Since the voltage supplied from the commercial power source in the second path is applied to the manipulator, the robot body becomes freely movable without being controlled by the manipulator.

The robot makes an operator pay attention to that the safety device is set in cancel mode, and is hence safer. In the robot, all input connectors of the safety device wired from the outside are identical connectors. The connector has a terminal for feeding a status aside from a terminal for connecting to the safety device. Depending on status input from the outside, a warning sign is displayed on a display device. The warning sign is displayed only when a controller is operated.
