New info on a few Darpa projects

DARPA also developed the Wasp, a small unmanned aerial vehicle that weighs two-thirds of a pound, can be carried in a backpack and can fly reconnaissance missions for as long as two hours. Its sensors provide imagery to small military units on the ground, operating in urban areas.

The operator throws the battery-powered device into the air after the propeller is spinning and controls it with a hand-held device that has a seven-inch color screen. It provides real-time pictures for U.S. Marine units, which have been testing it since last October. Hundreds are now in use in Iraq.
