Paper Abstract

This paper describes an integral approach to the acquisition of randomly moving objects with a robot. The acquisition problem is phrased as a feedback control problem that explicitly models the target dynamics but justifiably excludes the robot dynamics. The target's position deviation with respect to the robot is sensed by a camera mounted within the end-effector and used to servo the robot governed by controller-observer pairs. Acquisition takes place once the system is sufficiently certain about the target's motion pattern. A good balance is found for the trade- off in this phase between a decreasing field of view for the camera and the need to get close for acquisition. The approach was tested on a PUMA-560 robot with a gripper mounted camera. The experimental system can acquire objects that are moving randomly on a table; an early version was integrated in a kitting robot cell.
