Abstract:
1. An apparatus for calibration of an industrial robot, the apparatus comprising a body having a first angle-measuring member arranged for measuring an angle relative to the vertical line about a first measuring axis, mounting means for mounting the body to the robot during the calibration, and a second angle-measuring member arranged for measuring an angle relative to the vertical line about a second measuring axis differing from the first measuring axis, wherein said mounting means comprises a first mounting arrangement for mounting the body to a plane of reference of the robot, the mounting arrangement comprising three protruding contact elements being arranged so that the body is in contact with the plane of reference through said contact elements during the calibration, wherein said mounting means further comprises a second mounting arrangement for mounting the body to a second plane of reference on the robot, wherein said second mounting arrangement is arranged in an angle relative to the first mounting arrangement, and wherein said angle essentially corresponds to the angle between two planes of reference of the robot when the robot is in its calibration configuration.
