Robotic Pack Mule
Take a look at this robotic pack mule being developed by the military. Named BigDog it can carry 120 lbs and is able to traverse any terrain ranging from loose rocks, mud, snow and hills.
The best part about this video is watching what happens when one of the staff gives it a healthy kick. Instead of toppling over like one would expect, the robot positions its legs in order to regain its balance just like an animal might. The fluidity of motion starts to get a little creepy actually.
