I would buy one of this if they were in the market, as a security droid. a burglar finding such a thing would soil his pants to death! if that doesn't work, well, try a 40 watt range plasma rifle. seriously, this robot could handle stairs and climb on trucks, ASIMO does the same on a much more complicated way, like a human, why didn't we got this things crawling all arround back then? at least in places where no human would want to be.
