Abstract: A mobile robot or automatic guided vehicle having a multijointed robot arm. The robot arm has a gripper and charge coupled device camera mounted at the free end of the arm. The gripper is for engaging, holding and releasing workpieces. The robot arm transfers workpieces to and from process machines or storage areas. The robot arm finds the workpiece or the place to set it down by looking at two light emitting diodes placed a known distance and orientation away from the workpiece or set down place. The robot arm and camera are controlled by a computer on board the vehicle. The automatic guided vehicle and robot arm are used to transfer workpieces from place to place in an automated manufacturing environment.

Abstract: A robot assembly for acquiring unorientated workpieces from a bin. A sensing system views the bin and collects data. A computer analyzes the data to determine candidate holdsites on the workpiece. The hand of the robot assembly then engages a workpiece at a selected holdsite. The workpiece is moved to a pose where the position and orientation of the workpiece are determined. After this determination, the workpiece may be disengaged, or moved to an intermediate or final goalsite. The method is applicable to workpieces that have six continuous unknown degrees of freedom. Furthermore, partial occlusion of the workpiece by the robot hand is allowed.
