I have written about DARPA several times in this blog…for those that do not know they are a government agency that is tasked with doing research to find the impossible. Most of their projects fail, but the ones that do not are pretty useful, for instance: the internet, GPS, and stealth technology. Anyway, their latest project seems pretty cool: Human Robots.
I know they are a work in progress and far away from being useful, but these will someday be our soldiers. They may even be more than that: Think sci-fi here.
Here is an article on the topic: http://www.engadget.com/2012/04/06/darpas-next-grand-challenge-to-focus-on-humanoid-robots/
