The US Defense Department wanted to design the biggest and baddest high tech assistant for our military, and decided to copy a dog. Big Dog is the size of a Great Dane, can run about 4 mph, and can carry heavy equipment. I'm glad they have dog robots now, I didn't really want to go to Iraq anyway.
Big Dog can walk, run, and climb with it's tough aluminum legs on all kinds of rocky terrain. They say this is just the beginning, and plan on building more advanced models with optical sensors and a higher level of artificial intelligence.
