AF: Meet Spot, the robot dog that can run, hop, and open doors

I can't post this video directly, so just use this link.  

The robots that kind of freak me out are the ones that look and move like big snakes that are designed to worm their way through rubble to find survivors in case of an earthquake or other catastrophic building collapse.  Don't get me wrong:  I want to be found if I'm ever alive under thousands of tons of rubble, but I know when that snake shows up and works its way over to me, I'm going to be crying in fear and relief.
