"MAVs" or Micro Aerial Vehicles

In this photo taken from computer animation video Friday, Nov. 21, 2008, and released by the U.S. Air Force, shows the next generation of drones, called Micro Aerial Vehicles, or MAVs.

The MAVs could be as tiny as bumblebees and capable of flying undetected into buildings, where they could photograph, record, and even attack insurgents and terrorists.

U.S. military engineers are trying to design flying robots disguised as insects that could one day spy on enemies and conduct dangerous missions without risking lives.
