Title:
ROBOT SYSTEM POSITIONING ACCURACY MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2022/195938
Kind Code:
A1
Abstract:
According to the present invention, an identification figure (111) is disposed on one of a moving body (105) or a tip of a robot of a machine tool, and a camera is disposed on the other of the moving body (105) or the tip of the robot. The moving body (105) and the tip of the robot are positioned at a first position, the identification figure (111) is imaged by the camera, and on the basis of the image, the relative positions of the camera and the identification figure (111) at the first position are calculated. Next, at least one of the robot and an automatic guided vehicle is operated to position the tip of the robot at a predetermined second position and move the moving body (105) in the same direction by the same distance to image the identification figure (111). Next, on the basis of the obtained image, the relative positions of the camera and the identification figure (111) at the second position are calculated, and on the basis of the relative positions of the camera and the identification figure at the first position and the second position, the positioning accuracy of the tip of the robot is calculated.
