Self-replicating Robots (video)

Google video of the self-replicating robots at Cornell – “One of the dreams of both science fiction writers and practical robot builders has been realized, at least on a simple level: Cornell University researchers have created a machine that can build copies of itself. Admittedly the machine is just a proof of concept — it performs no useful function except to self-replicate — but the basic principle could be extended to create robots that could replicate or at least repair themselves while working in space or in hazardous environments” Link.
