They are careful to point out that it walks heel-to-toe like a human. Why did they design the robot to do this? Humans only walk heel-to-toe when they wear shoes. Does a heel-to-toe walking pattern give the robot any particular advantages? Did they just design it in to make the robot appear to have a more human gait? I find this very interesting.
Also, I noticed that the robot is wearing rock climbing shoes - the 5.10 coyote to be exact. I am guessing that this is for better traction on the tread mill. Rock climbing shoes have very thin soles with no cushioning whatsoever. No human would be able to walk with a heel-to-toe gait wearing those shoes on a hard surface without considerable heel pain after a few strides.
It explains it in the article -- the robot is designed to simulate the motion of real, human soldiers in order to test protective, anti-chemical gear for the military (both walking and crawling apparently). It'll also be able to regulate temperature and sweating.
