Engineers at Northwestern University have developed nano-scale robots that scuttle like small peekytoe crab. The tiny crab-bots measure around half-millimeter wide. Like the decapod crustaceans, the bot can bend, twist, crawl, walk, turn and even jump. Not only the nano crab like devices, engineers have also created same sized robotic inchworms, crickets and beetles. Researchers envision that their technology will explore practical tasks inside tightly confined spaces.
