Hopefully Wikileaks will survive so I might know the wedding parties and whatnot that this thing wiped out "accidently" in the "war on terror". Otherwise, cool technology.
I have to disagree with you here. Look again at the rocky steps the robot walks down (0:19 and 0:50), and the slope of the hill it's climbing. It's hard to make a wheeled robot that can climb (400 lb. payload -- 1200 lb. unloaded) a hill of that slope in loose/rocky dirt.
