Researchers at Harvard's Wyss Institute have created what they're calling RoboBees - robots smaller than a penny that can fly.
Inspired by the biology of a fly, with submillimeter-scale anatomy and two wafer-thin wings that flap almost invisibly, 120 times per second, the tiny device not only represents the absolute cutting edge of micromanufacturing and control systems, but is an aspiration that has impelled innovation in these fields by dozens of researchers across Harvard for years.
