Abstract

Vision systems have been widely used to provide adjustment to robot positioning in order to compensate for variation in work position. This paper presents a calibration procedure for determining location for a vision camera mounted on the distal link of a SCARA-type assembly robot. The calibration procedure considers robot's discrete addressability, camera misalignment, and transmission imperfection.
