These Robots Are Getting Pretty Good

You have to admit that there is some pretty cool technology here in Boston.

Take this for example. A couple of years ago I had seen these protypes from Boston Dynamics that look like a robotic mule a couple of years ago but then they were always tethered and on relatively tame terrain.  Now seeing these more advanced versions I'm amazed.  They are navigating some serious terrain (steep hills, snow, ice, water, etc.).  The commercial applications aren't obvious to me but the military ones sure are (and judging from their website, that's what Boston Dynamics is focused on).  The video is long (the Terminator sound track doesn't help) and shows the mule-thing for the first 6 minutes followed by short snippets of various prototypes.
