Boston Dynamics' "Big Dog" All-Terrain Robot Videos for Engineers
This clip looks like something from an alien invasion movie, but it is a real automaton design and built by Boston Dynamics. "Big Dog," as it has been dubbed, was created in a DARPA research and development contract to provide a vehicle for lugging soldiers' battle gear across rough terrain in order to unburden the soldiers.
There is more computing power hardware and software in that thing than in any of the Apollo moon shots. Amazing.
