    • A method for calibration of an industrial robot having a plurality of sections movably connected to each other for rotation about a plurality of movement axes, wherein an angle measuring member (7) is mounted on the robot so that it measures angular changes of the axis or axes to be calibrated, relative to a vertical line. The method comprises measuring a reference direction, selecting at least one of said axes as a calibration axis (10) and another of said axes as a measuring axis (14), moving the robot between at least two calibration positions, wherein the moving includes rotating the robot about the measuring axis, and the calibration positions are selected such that the direction of the calibration axis differs from the vertical line, reading angular values from the angle measuring member in said calibration positions, and calibrating the calibration axis based on said angular values and the measured reference direction.
    • 一种用于校准具有多个部分的工业机器人的方法,所述多个部分彼此可移动地连接以围绕多个运动轴线旋转,其中角度测量部件(7)安装在机器人上,使得其测量轴的角度变化或 要校准的轴相对于垂直线。 该方法包括测量参考方向,选择所述轴中的至少一个作为校准轴(10),将另一个所述轴作为测量轴(14),在至少两个校准位置之间移动机器人,其中移动包括旋转 选择关于测量轴的机器人和校准位置,使得校准轴的方向与垂直线不同,在所述校准位置读取角度测量构件的角度值,并且基于所述角度值校准校准轴 和测量的参考方向。
