ABSTRACT:
A position error correcting method and apparatus suitable for operating an industrial robot with high accuracy, in which, after the industrial robot disposed on a working site is moved according to position command values, the moved position of a measurement point on the industrial robot is measured three-dimensionally, and a position error of the industrial robot between the robot coordinate system relating to the operation of the industrial robot and the absolute coordinate system of the industrial robot on its working site is computed by comparing the measured position values of the measurement point with the position command values. The work program prepared for the operation of the industrial robot is modified on the basis of the computed position error so that the industrial robot can be operated in accordance with the work program from which the source of the position error has been eliminated.
