DARPA has approved a research contract with Iconsystems Corporation for the development of swarm intelligence software. As part of the contract the software will be tested using a real swarm of 120 autonomous mobile robots. It is hoped that useful complex behaviour will emerge in the swarm when simple rules are carried out by each robot; much like the complex behavior of ants emerges from simple actions of each individual ant.
