Scientists at Work on Robobugs

Washington Post : A number of U.S. government and private entities are trying to develop insect-size spy drones. Some federally funded teams are even growing live insects with computer chips in them, with the goal of mounting spyware on their bodies and controlling their flight muscles remotely.

The robobugs could follow suspects, guide missiles to targets or navigate the crannies of collapsed buildings to find survivors.

The technical challenges of creating robotic insects are daunting, and most experts doubt that fully working models exist yet says Washington Post correspondent Rick West .
