Smart camera system helps calibrate high-precision robotic drilling.
The F-22 Raptor is a Stealth fighter aircraft that requires extreme precision at all stages of manufacture to maintain the lowest possible radar signature. One fastener protruding above the surface of the aircraft skin by only the thickness of a piece of paper could expose the craft to enemy radar. There are thousands of fasteners that attach the composite skin to the airframe, and every one needs to be perfect.
