Rolls-Royce is building cockroach-like robots to fix plane engines

Typically, engineers want to get bugs out of their creations. Not so for the U.K. engineering firm (not the famed carmaker) Rolls-Royce -- it's looking for a way to get bugs into the aircraft engines it builds. They're tiny robots modeled after the cockroach. On Tuesday, Rolls-Royce shared the latest developments in its research into cockroach-like robots at the Farnborough International Airshow. Rolls-Royce believes these tiny insect-inspired robots will save engineers time by serving as their eyes and hands within the tight confines of an airplane's engine.
