Navy and Air Force have recently warmed up to a new robotic friend, a number of military bots-to-be showed their stuff at DARPATech 2007. Among the standouts were a camera-guided Little Dog, the resilient Big Dog, a backpack-portable, fully autonomous Micro Air Vehicle, and a beefed-up version of the MAV (dubbed the Organic Air Vehicle) that can reportedly hover around for two hours. The latter creation was designed to "designate ground targets from the sky and paint targets up to 15-kilometers away with its laser designator," while the MAV can monitor a 10-kilometer radius "with infrared or visible cameras in hover-and-stare mode." The aforementioned canines seem to be terrain navigators, which could potentially be studied to improve the locomotion of walking machines in general. Go on, click through for a few glimpses of these friendly fellows -- they aren't armed, yet.
