Photos: Building an army of robots

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.
