Abstract
A method for automatically calibrating an external force measuring device of an industrial robot. The industrial robot has a multi-axis robot arm, the robot arm has, for each joint axis, an electric actuator (M1, . . . M6) and a position sensor (C1, . . . C6) able to measure the joint position of the corresponding joint. The robot has a force measuring device. The force measuring device has at least one measuring sensor capable of measuring the forces applied to the robot arm. The method updates an applied force correction coefficient by incrementing it with a value proportional to the average force of the external forces exerted if certain conditions are met.
