ABSTRACT:
A symmetry calibration method for calibrating multi-configuration robots is disclosed. Specific points in the robot envelope are selected and the robot is moved to each point twice using different configurations. A linear measurement is made from an arbitrary fixed surface to a selected point on the robot at each envelope point. The origin for an axis is determined when the measurements for both configurations at the envelope point are substantially equal.
