The U.S. military is researching a future generation of flying robots that can hunt, photograph, record and even attack enemy insurgents and terrorists.
Researchers at Wright-Patterson Air Force Base in Dayton say the new robots will be as tiny as a bumblebee and disguised to look like one. They say the flying robots could slip into buildings and spy on enemy soldiers.
Unmanned Aerial Vehicles are being used in Iraq and Afghanistan so the military can conduct dangerous missions without putting pilots and expensive aircraft in harm's way.
The tiny versions probably won't be ready until 2030. But by 2015, the military hopes to have bird-sized robots ready to deploy.
