CONTROL METHOD FOR AN INDUSTRIAL ROBOT

摘要

The invention relates to a method for controlling an industrial robot and, more particularly, to a method for reducing thermal influencing variables, whereby reference measuring points are arranged in the working area of the robot, which are traversed by the robot. The actual data of the reference measuring points is processed by a computer with the purpose of obtaining correction data that is fed to the control electronics of the robot. According to the invention, an error model is configured that corrects thermal positioning and/or orientation errors without having to determine the actual temperature on the robot.
