Already in action with human drivers, the U.S. Army's Stryker is being testing with robots at the wheel. Recently, over a 100 mile winding test course, a driverless Stryker averaged 22 mph and hit a top speed of 40 mph. The robot Stryker is expected to see action in 2010.
iRobot, the company that makes the Roomba and Scooba robotic floor cleaners, and John Deare teamed on R-Gator, which is designed to be a scout, perimeter guard, ammo carrier and more for soldiers in a combat zone.
The PackBot from iRobot can climb stairs and carry a camera on its arm. The robot is already being used in Iraq and Afghanistan.
