Abstract
Disclosed is a calibration method for compensating an offset occurring when parts in an industrial robot are exchanged with now 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.
Claims1
A calibration method of an industrial robot, the robot being normally operable to carry out an industrial job, the method comprising the steps of:
- A. providing a signal generation part attached on a movable part of the robot for providing a signal about a position of the movable part, and a signal detection part for detecting the signal from the signal generation part;
- B. acting on the movable part for producing an offset thereof from a desired initial position;
- C. performing a calibration operation separate from the normal operation by moving the offset movable part;
- D. generating calibration data on the basis of the position of the offset movable part detected by the signal detection part;
- E. calculating a difference between the generated calibration data and preset calibration data;
- and
- F. amending the preset calibration data on the basis of the difference so that the offset is compensated.
