ABSTRACT:
Apparatus for acquiring individual workpieces from a supply of randomly oriented workpieces in a storage bin or the like. The apparatus includes a movably mounted head assembly having a gripper connected thereto by an intermediate flexible support. A sensor generates a control signal responsive to a contact force exerted by the gripper on a workpiece. The gripper operates to grip the workpiece contacted thereby. The flexible support is then retracted to lock the gripper against an abutment surface fixed relative to the head assembly. Operation of the gripper and/or movement of the head assembly may be controlled in response to said control signal.
