Document Type and Number:
WIPO Patent Application WO/2021/075876
Kind Code:
A2
Abstract:
The disclosed invention relates to a method for correcting the precision of a multi-articulated robot arm. Provided is a method for correcting the precision of a multi-articulated robot arm, wherein: a reference object is fixed and installed around the multi-articulated robot arm, which is provided with N joints, and a dynamic object is installed at an arbitrary position past the N-th joint of the multi-articulated robot arm; and, after images of the reference object and the dynamic object are acquired using an image scanning device, the rotation axis of each of the joints aligned with respect to the image of the reference object can be determined by extracting a single circle from images of three different orientations of each of said joints.
