Boston Dynamics' LS3, better known 'round these parts as AlphaDog, has already wowed us with a display of its stability, power and mobility. Thing is, that little clip we caught back in October took place entirely within the safe and purposefully laid out confines of a laboratory. So, the question is, what happens when you take the rather noisy quadruped outside and strap a bunch of weight to it? Well, pretty much the same thing that happened while it was nice and cozy inside -- the beast powered through the reasonably rugged terrain with nary a hitch. By the end of the tests DARPA hopes to have a mighty robotic porter capable of carrying 400 pounds of gear up to 20 miles without refueling. Though, the trek is expected to be slow and arduous as a full 24 hours is target time frame for such a journey. For full PR and to see the bot in action head on after the break.
