DETERMINING A CALIBRATION POSITION OF A ROBOT JOINT

摘要

An arrangement for determining the calibration position of a robot joint comprises the joint comprising a moveable joint element (54) and a stationary joint element (56), where one joint elements comprises a holding structure (60, 62) and the other a force providing protrusion (64), a robot controller, a motor (22) connected between the robot controller and the moveable joint element and a force receiving element (58) adapted to form a kinematic coupling with the holding structure (60, 62) and the force providing protrusion (64), where the kinematic coupling has at least two areas of contact between the structure and the force receiving element and one area of contact between the force providing protrusion and the force receiving element, the force receiving element (58) being fastenable to the holding structure for stretching out across a gap between the two robot joint elements for receiving a force from the force providing protrusion.
