An industrial robot device in which deviation between an offline-teaching instruction and an actual movement of a robot according to the instruction can be eliminated. The elimination of deviation is accomplished by adjusting absolute X, Y and Z axes of software for driving the robot with respect to those of a processing machine which operates together with the robot.

A method for operating an industrial robot device, comprising the steps of: providing a robot having a base having at least two nonparallel robot installation reference surfaces formed thereon and movable arm means supported by said base; positioning said robot so that said robot installation reference surfaces abut corresponding installation reference surfaces of a processing machine; positioning optical detecting means in at least first and second planes on said processing machine separated from but having a predetermined spatial relationship with respect to said installation reference surfaces of said processing machine; positioning an end of said movable arm means at a first reference position designated by a software instruction in accordance with a set of software absolute coordinate axes in a vicinity of said optical detecting means; projecting at least two beams of light from said end of said movable arm means in a direction of said optical detecting means; detecting a position of said beams of light on said optical detecting means; determining an amount of deviation of said first reference position from a second reference position fixed with respect to said installation reference surfaces of said processing machine; and modifying said software absolute coordinate axes in accordance with said amount of deviation.
