Abstract/Summary A method in an industrial robot for increasing the accuracy in the movements of the robot, where a tool supported by the robot is brought to adopt a plurality of positions generated by the control system, which are each determined by a measuring system, whereby a deviation between the generated position and the position determined by the measuring system is introduced as a correction in the control system for adjusting the movement. The generated positions and the positions determined by the measuring system, respectively, are adapted to form a first path an a second path, respectively, whereby the correction is determined by a path deviation between geometrically calculated positions in the respective path.
