Satellite imagery of giant robot under construction at Area 51

Enter the coordinates for Area 51 into Google Earth and the satellite image reveals either a shadow or, more likely, a massive robot under construction. Scott C. Waring of UFO Sightings Daily writes:

When I checked through the past photos of that location, I notice that the figure actually moves onto its side, then changes its poses each photo! It actually moves. Now, perhaps some USAF soldier is playing around for years doing this, or perhaps Area 51 is experimenting with 16 meter tall robots that could one day be used in combat missions.
