F-22 (Raptor) Large Painting Robot The two pictures (on the left and below) are of a large robot that I designed and built as part of the core team at Pratt & Whitney. The 40 feet tall robot shown here was an offshoot of the Large Aircraft Robotic Paint Stripping (LARPS) system that was initially developed under the Air Force's Manufacturing Technology (MANTECH) program for the Oklahoma City Air Logistics Center. The large robot has a 28-foot horizontal reach and the spray head can be raised as high as 26 feet. The aircraft's exterior is painted with a standard six-axis spray head mounted on a hydraulically-operated arm that can be raised and lowered and is, itself, attached to a movable platform. This wire-guided platform, called an Automated Guided Vehicle (AGV), features electric drive wheels and hydraulic stabilizing jacks and is positioned at several points around the aircraft as it is being painted. |

The large robot allows for precise application of the aircraft's paint. Unlike many other aircraft, where a base coat is applied over the entire aircraft, and then the camouflage coat is added on top of that, the F-22's two-tone camouflage scheme of dark gray on a light gray is actually applied separately. The robot first paints the light gray surrounding what will be a camouflage area, but leaves a hole where the dark gray will go. It then goes back and adds the dark gray. This saves paint, but more importantly, doesn't add additional weight anywhere on the aircraft. |
