New Robots Clone Themselves: "Mimicking reproduction in living organisms, researchers have built a simple self-replicating robot out of automated blocks.
Machines that can copy themselves have been built before, but the earlier experiments were limited to two dimensions or confined to a track. Hod Lipson and his collaborators at Cornell University have designed modular cubes, called molecubes, that can assume a range of three-dimensional shapes."
This is cool! I want a kit of my own!
