Had I looked further on this authoritative site I would have found http://www.flatwoodsmonster.com/ and realized that the "authorities" have already probably reverse-engineered such a robot as far back as 1952. "One of the strange objects crash-landed on a rural hilltop in Flatwoods, West Virginia. A group of schoolboys saw the object maneuver across the sky and seemingly fall to Earth.... Soon a twelve-foot tall being [robot] from the downed craft terrified these innocent people. This being became known as “The Flatwoods Monster,” or “The Braxton County Monster.” Whoa... why should we be worrying about globabl warming with this kind of thing going on in West-by-god Virginee....
