PROCESS AND DEVICE FOR CORRECTING THE POSITION OF INDUSTRIAL ROBOT ARMS

摘要

The invention concerns a process for correcting by means of a position sensor the position of the free end of a robot arm which has deviated from its set position, in particular as a result of flexions and/or torsions. The robot arm comprises at least one connecting element which prolongs at least one joint or a corresponding base. The deviation from the position at the end of the connecting element is measured by an energy beam emitted by an energy emitter arranged at the other end of the connecting element and is corrected automatically by the process described in Patent...(Patent application P36 14 122.4-32) in function of the measured deviation of the robot arm, which is returned to the set position. The energy beam is directed by an essentially non-loaded measurement drive in function of a predetermined set value.
