Zusammenfassung:	A robot calibration method which aligns the coordinate system of a gantry module with the coordinate system of a camera system is disclosed. The method includes using an alignment tool, which allows the operator to place workpieces in locations known by the gantry module. An image is then captured of these workpieces by the camera system. A controller uses the information from the gantry module and the camera system to determine the relationship between the two coordinate systems. It then determines a transformation equation to convert from one coordinate system to the other.
