ABSTRACT:
Disclosed is a calibration method for compensating an offset occurring when parts in an industrial robot are exchanged with new ones. A signal generation part is attached to a moving part of the robot. While the moving part is moving, a signal detection part detects the movement of the signal generation part with a sensor therein, and calibration data are generated on the basis of the detected signals. Preset calibration data are amended using a difference between the generated calibration data and the preset calibration data, so that the offset is compensated.
