Abstract We describe mobile robots engaged in a cooperative task that requires communication. The robots are initially given a fixed but uninterpreted vocabulary for communication. In attempting to perform their task, the robots learn a private communication lan­ guage. Different meanings for vocabulary elements are learned in different runs of the experiment. As circumstances change, the robots adapt their lan­ guage to allow continued success at their task.
1 Introduction In this paper, we investigate the evolution of simple com­ munication protocols among nonverbal subjects engaged in cooperative tasks. Gregarious animals, small children, and even adult humans lacking common language engage in such activity routinely. Grunts, gestures, and other nonverbal signals take on mutually agreed­upon mean­ ings in the context of cooperative tasks. ``Follow me,'' ``Look out!'' and ``Raise your end of the table higher'' can all be conveyed without previously agreed­upon lan­ guage. Satisfactory completion of cooperative tasks such as table­carrying, hunting, or tribal survival often de­ pends on making effective use of such communications. This paper describes an example of a cooperative task---coordinated movement---achieved by a troupe of mobile robots. Depending on circumstances, different \Lambda This report describes research done at the Artificial In­ telligence Laboratory of the Massachusetts Institute of Tech­ nology.
