Harvard researchers have developed a robotic fly with a three centimeter wingspan that weighs only 60 milligrams. Beyond that it actually flies. The real fly was used as a model for the robot's mechanical movements. In the future such micro fliers could be used as spies. So, if you think a room is bugged, pat down the flies and mosquitoes.
Implications - The project is being led by Professor Robert Wood who is a professor at the university's school of engineering and applied sciences. This is actually being funded by the U.S. Defense Advanced Research Projects Agency. They hope that the robotic fly will be used for surveillance purposes in the battlefield and urban environments.
