Abstract

PURPOSE:To enable always performing of an accurate coordinate conversion regardless of any positional deviation in any or both of a robot and a camera, by mounting a template having a mark for coordinate conversion at a mobile part of the robot. CONSTITUTION:A robot controller 2 of a robot 1 is connected to a visual controller 3 and a console 10 is connected to the controller 3 to output an instruction of coordinate conversion while a template 5 having a mark 6 is mounted at the tip of a mobile part 9 of the robot 1. Then, a coordinate conversion formula is calculated with a camera 4 for taking the mobile part 9 form coordinates of the mark 6 in a robot coordinate system and those of the mark 6 in a visual coordinate system at respective working points to match both the coordinate systems. This enables accurate coordinate conversion regardless of any positional deviation in any or both of the robot 1 and the camera 4.
