Abstract: Automatic methods and robotic system for processing workpieces are provided. A method for locally re-shaping a moldable workpiece includes receiving data in an input module indicating a present form of the workpiece; providing a robot configured to pass the workpiece through a machine; determining, with a control module, a path of the robot based on the present form of the workpiece and a target form of the workpiece; and performing a finishing process by passing, with the robot, the workpiece through the machine along the path, wherein the machine re-shapes the workpiece with the target form.

Abstract: Robotic systems and methods are provided with an end effector having lockable compliance. A robotic system for manipulating a workpiece includes an arm having a pair of sections connected by a joint assembly, with a lock disposed in the joint assembly. A gripper is connected on the arm and is configured to alternately grip and release the workpiece. A controller operates the lock to alternately lock and unlock the joint assembly. The gripper holds the workpiece during a deformation of the workpiece, while the controller may unlock the lock to allow movement of the joint assembly to relieve forces on the arm arising during a deformation of the workpiece.

Abstract: A system for evaluating a rigidity of an angle bracket includes a test system having a first test fixture and a second test fixture. The system includes an angle bracket coupon including a first wall, a second wall coupled to the first wall at a bend to define an angle between the first wall and the second wall, and at least one three dimensional feature defined at the bend that extends between the first wall and the second wall. The angle bracket coupon is to be coupled to at least one of the first test fixture and the second test fixture to evaluate the rigidity of the angle bracket.
