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.
Claims18
An industrial robot, comprising:
- (a) a robot body;
- (b) a manipulator to control an operation of said robot body;
- (c) a control device to control said manipulator;
- (d) a first path disposed between said manipulator and said control device;
- and
- (e) a second path disposed between a commercial power source and said manipulator,
- wherein when a voltage supplied from said commercial power source in said second path is applied to said manipulator, said robot body becomes freely movable without being controlled by said manipulator.
A method of operating an industrial robot having a robot system comprising a robot body;
- a manipulator to control the operation of said robot body;
- a control device to control said manipulator;
- a first path disposed between said manipulator and said control device, and a second path disposed between a commercial power source and said manipulator;
- said method comprising the steps of:
- (a) operating said manipulator by controlling said control device by said first path, thereby controlling the operation of said robot body;
- and
- (b) freely moving said robot body without being controlled by said manipulator by applying a voltage from said commercial power source to said manipulator via said second path when said manipulator is unable to be controlled by said control device via said first path.
