Abstract
An apparatus for calibration of an industrial robot, the apparatus comprising a body (7) having a first angle-measuring member (10) arranged for measuring an angle relative to the vertical ine about a first measuring axis (12) and mouting means (8, 9, 25) for mounting the body to the robot during the calibration. The apparatus comprises a second angle-measuring member (11) arranged for measuring an angle relative to the vertical line about a second measuring axis (13) differing from the first measuring axis. A method for calibration of an industrial robot having a plurality of sections movably connected to each for rotation about a plurality of axes, using an apparatus according to claim 1 or 2, the method comprising: attaching the body (7) to a section of the robot, reading an angle measurement from the first angle-measuring member (10), moving the robot about a first axis in dependence of said angle measurement for the first angle-measuring member (10), reading an angle measurement fro the second angle-measuring member (11), and moving the robot about a second axis in dependence of said angle measurement from the second angle-measuring member (11).
