The robotic system forms a curved bumper from a straight bumper bar and includes a hydraulic press with a die set therein for placing curved surfaces on bumper bars. A gravity feed magazine loader is located on one side of the press and an electronic checking apparatus is located at the other side of the press for measuring the surfaces on curved bumper bars. A robot is located in the space between the loader and the checking apparatus. The robot has an end effecter having a frame and carrying first and second pairs of spaced apart grippers, with the first pair of grippers being closer together than the second pair of grippers. The first pair of grippers picks up and hold a straight bumper bar and it is delivered by the robot from the loader to the hydraulic press and die set. The second pair of grippers picks up and holds the curved bumper after it has been removed by the robot from said hydraulic press and die set and delivered it to the checking apparatus where the bumper surfaces are measured and the data fed to a PLC.
