Self Replication

Self Replication is a process in which devices whose diameters are of atomic scale, on the order of nanometers, create copies of themselves. Self-replication in robotics has been an area of research and a subject of interest in science fiction. It is a tiling pattern in which several congruent tiles may be joined together to form a larger tile that is similar to the original. Most self-replicating systems, including biological life, and is simpler in that it does not require the program to contain a complete description of itself.
