Abstract This paper presents a new experiment that has been carried out in the context of the research on the origins of language that is going on at the Free University of Brussels. Two mobile robots ground time series of motor commands into cate­ gories. The categorization is based on the theory of phase space reconstruction and learning by gen­ eration and selection. Besides the categories, the robots try to develop a lexicon. Lexicon forma­ tion occurs within the concept of language games in which agents can communicate about a topic and try to develop a coherent communication sys­ tem. Again this is learned by generation and se­ lection. The paper concludes that although the categorization works fine, the success of the lexi­ con formation is still unsatisfying.
1. Introduction How does a communication system develop? This is a question that interests researchers already for many centuries. Recently the question can be investigated empirically by using robots. This paper presents one of these recent investigations. Before the above ques­ tion is discussed, it should be clear what communica­ tion system the robots try to develop and how. The communication system they might construct could be tactile (as in (Barnes et al., 1997)), but a language­ like lexicon may be more useful if the robots need to work with generic tasks. Such communication systems have already been developed (Billard and Hayes, 1997, Yanco and Stein, 1993). But in the work of Billard and Hayes a part of the lexicon has been preprogrammed. The work of Yanco and Stein heavily depends on a hu­ man instructor. From a scientific point of view it would be more interesting if the robots could ground the lan­ guage system themselves. This paper reports a new experiment in which two robots try to develop a ...
