Abstract
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 ine about a first measuring axis () and mouting means () for mounting the body to the robot during the calibration. The apparatus comprises 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. 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 claimorthe method comprising: attaching the body () to a section of the robot, reading an angle measurement from the first angle-measuring member (), moving the robot about a first axis in dependence of said angle measurement for the first angle-measuring member (), reading an angle measurement fro the second angle-measuring member (), and moving the robot about a second axis in dependence of said angle measurement from the second angle-measuring member ().
