PROFILE CONTROLLER FOR ROBOT

PURPOSE: To automatically generate a copying operation locus, by mounting a control part for operating a relative position and an attitude angle of a sensor of an image pick-up means and a work on the basis of an image information signal relating to a slit image projected on a work surface, and moving a head part at every predetermined specific pitch. CONSTITUTION: The slit images 20a, 20b on a work 9 are picked up by an image pick-up means 17 of a hand head part 5, and the condition of the slit images is detected by an image detecting means 19. The position between a sensor 15 of the image pick-up means 17 and the work 9, and the attitude are operated by an operating means 13 on the basis of the detected data. Simultaneously, an interval between a start point and an end point of the work 9 is divided according to a predetermined pitch interval which is variably programmable, and a partial surface shape of the work on each divided reference point, is automatically measured by a measuring means 13. The relative position between the sensor 15 and the work 9, and the attitude angle operated in advance, is corrected by a correcting means on the basis of these measurement data to obtain a desired value. Whereby the copying shape locus of a hard head part 5 between the start point and the end point of the work can be automatically generated.
