This thing is absolutely insane. It's a remote controlled robot that looks like some kind of crazy spider dog with 4 human legs. Big Dog jumps, can carry loads, walk on snow, ice, rocks, up hills, etc. The St. Bernard is in for a challenge on the ski-lifts. Among other applications, of course.
This could also signify the end of the world or that we are getting closer to some Space Odyssey 2001 Robocop Terminator land. Regardless that is one crazy remarkable robot. Check out the official link to the Boston Dynamics site here. Props to Dart for the link, I hope I didn't scoop Hellyup.
