This paper gives a brief overview of our experimental work using groups of robots using simple forms of communication to perform cooperative tasks. We describe three sets of robot experiments using simple cmnmunication strategies to augment fimited sensing and effectors. Ill the first set, a group of robots used connnunication to learn social rules. In the second set, communication was used to compensate for limited sensing on individual robots in order to cooperate on pushing a large box. Finally, in the third set, of experiments, the same two robots learned a simple communication protocol that enables them to push the box. In all three cases the communication strategies are implemented as simple behaviors easily incorporated into the robots’ behavior-based controllers.
