Reign of the Robot Donkeys

WildCat is a four-legged robot being developed to run fast on all types of terrain. So far WildCat has run at about 16 mph on flat terrain using bounding and galloping gaits.

On a scarier note, WildCat is being developed with funding from DARPA's M3 program. Yes, those are the people who hope someday to bring you robot soldiers and robot armies.
