Self-replicating robots are no longer the stuff of science fiction.

Scientists at the Cornell University in Ithaca, New York have created small robots that can build copies of themselves.

Each robot consists of several 10-cm (4 inch) cubes which have identical machinery, electromagnets to attach and detach to each other and a computer program for replication. The robots can bend and pick up and stack the cubes.
