Method and device for correcting the position of industrial robot arms

摘要

The invention relates to a method for correcting the position of a free end of a robot arm, deflected from its desired position in particular by bending and/or torsion, by means of a position sensor, the robot arm having at least one connecting element as an extension of at least one joint or a corresponding base, and the deflection from the desired position being measured at the end of the connecting element with the aid of an energy beam emanating from an energy radiator arranged at the other end of the connecting element of the robot arm and being readjusted automatically to the desired position as a function of the measured deflection of the robot arm, in accordance with Patent ... (Patent Application P 3614122.4-32), the energy beam being guided by means of a substantially unloaded measurement drive on the basis of a preset desired value.
