Harvard Scientists Demonstrate First "Flight of the Robobee"
Description:It's called Robobee. It's half the size of a paper clip and weighs less than a tenth of a gram. Robobee's evolution began ten years ago in a laboratory at the Harvard School of Engineering. But last year, its developers finally got their insect-inspired robot to fly. Robobee's anatomy is built on a submillimetre scale. It's kept aloft with ceramic wings that can be controlled independently, expanding and contracting at 120 beats per second when exposed to an electric field.(1:10)
