Abstract: A shear pin for calibrating an industrial robot, the shear pin including an elongated body including a weakening defining a break location in case of overload. The shear pin is configured to be mounted to a calibration pin holder on the robot. A maximum force that the calibration pin can exert on the robot during calibration can be easily limited by dimensioning the weakening appropriately.

Abstract: An arrangement for determining the calibration position of a robot joint where the joint has a moveable joint element and a stationary joint element, where one of the joint elements has a holding structure and the other a force providing protrusion, a robot controller, a motor connected between the robot controller and the moveable joint element and a force receiving element adapted to form a kinematic coupling with the holding structure and the force providing protrusion, 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 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.
