Fly Robot X220
Little bugs… for bugging people –

A life-size, robotic fly has taken flight at Harvard University. Weighing only 60 milligrams, with a wingspan of three centimeters, the tiny robot’s movements are modeled on those of a real fly. While much work remains to be done on the mechanical insect, the researchers say that such small flying machines could one day be used as spies, or for detecting harmful chemicals.

“Nature makes the world’s best fliers,” says Robert Wood, leader of Harvard’s robotic-fly project and a professor at the university’s school of engineering and applied sciences.
