Robot To Explore Mysterious Pyramid Passage

a_timid_mouse writes "The National Geographic Society, using the same kind of robot used to search for survivors in the ruins of the World Trade Center, is trying to solve a mystery that lies deep in the bowels of the 4,500-year-old Great Pyramid of Giza. Up a tiny square tunnel is a stone hatch with copper handles that was discovered in 1872. No one knows the purpose of the shaft, and no one knows what lies behind the hatch. Enter the Pyramid Rover."
