....In recent years an increasing number of studies have been done that investigate how a population of robots can develop a symbolic communication system. Although in most studies the communication system was given, e.g. 14] a few investigated how a communication system can emerge from scratch [10, 12, 13]. Each of these studies have had to tackle the anchoring problem [5] and the related symbol grounding problem [6] Both problems relate to the question how symbols relate to the real world. The anchoring problem mainly relates to the technical issue of how to construct and maintain a relation (or ....

....certain moments in time and when they developed bits of a language, they tended to use the language to select their target. The robots developed a lexicon from scratch using the guessing game model, which is based on Steels language game model and which has been implemented on real robots before [10, 12, 13]. The ideas were implemented in a mobile robot simulator in which an environment was designed containing four distinctively coloured landmarks. These landmarks functioned as charging stations where the robots could re ll their energy supplies by jointly visiting the vicinity of a station. The ....

....occupants [8, 17] This information retrieval system could seamlessly consider spatial context in the form of the models that we present. Several recent artificial intelligence approaches to representation attempt to learn meaning based on the cooccurrence of spoken words and physical objects [14, 18]. These techniques reinforce specific word sensor associations in an attempt to learn word meaning. The negotiated representation resides in the heads of the individual agents operating within the environment. In other words, the artificial intelligence community is interested in a vertical ....

....the evolutionary approach to agent communication research. Because the agents are autonomous, grounded, and situated, the possible words and possible meanings are not fixed but continuously change as the agents autonomously evolve their communication system and adapt it to novel situations [12]. Recently there has been a lot of research into evolutionary approaches to communication systems. 13] 14] 2 The Experiment The experiment consists of a World where Agents exist and the Agents themselves. The World has contained within it food cells, a nest and Agents. The World monitors the ....

....called DRAMA in the context of the imitation learning. Billard have shown that a mapping between a sequence of sensory data and its corresponding symbol can be learned. Steels and his colleagues have studied the evolution of language by conducting naming game experiments using physical robots [16]. It was demonstrated that diverse mappings between sensory states and names of objects can be self organized through the evolutional processes. Although both studies demonstrate the importance of the embodiment for the acquisition and usage of language, they have not been yet successful in ....

....about the world they lived in, i.e. the approach and avoidance of the mushrooms they encountered. Experiments on the development of language and meaning in groups of robotic agents through adaptive language games have been carried out by Steels (1998; see also Steels and Vogt 1997, Steels and Kaplan 1999). In the experimental setup used by Steels and Vogt (1997) a number of mobile robots moved around in a physical environment of limited size, containing some additional objects. The robots acquired a common vocabulary of word meaning pairs (where the meaning of a word is taken to be the sensory ....

....of the development and interaction of individual lexica of word meaning pairs in the course of the one to one language games performed by the robots. For a discussion of the semiotic dynamics resulting in this kind of experiment, e.g. the emergence and dampening of synonymy and polysemy, see also Steels and Kaplan (1999). Thus, in both these examples autonomous agents are not forced to learn a human language they could, due to their radically different physiology, not possibly understand. Instead they develop, in a process of self organization, their own language from the interaction with their environment and ....

....In particular, we have conducted a large scale experiment, called the Talking Heads , involving dioeerent robotic sites in dioeerent places of the world. This experiment has shown how a group of agents can build categories and words from scratch to name simple colored shapes on a white board (Steels and Kaplan (1999)) With the Talking AIBO project, we are investigating how these techniques could be applied to human machine interactions and in particular to interactions with autonomous robots. We have decided to keep the original autonomous behavior of the AIBO and build our system on top of it . The system ....

....non verbal features are present [Bre00] In Sony CSL Paris, we are currently working on a system enabling the AIBO to learn how to interact with humans using real words. This research relies on previous works showing how agents could build categories and words from scratch to name simple objects [SK99]. First experiments have been done showing how an enhanced AIBO could perform this task on top of its current autonomous behavior [Kap00] It is important for the design of learning artificial pets not to loose the features that have made the success of the more simple ones. That s why we argue ....

.... in the area of lexical semantics (Steels, 1996a; 1996b; 1997a) These results have been integrated in the Talking Heads experiment 1 , a large scale public experiment in which visually grounded and situated robotic agents autonomously develop a shared lexicon and ontology from scratch (Steels and Kaplan, 1999b) The agents use vision to make contact with the world. There are different physical installations (Paris, Tokyo, etc. connected through the Internet, and agents can teleport from one robot body to another thus experiencing different realities. The agents can also interact with humans so that ....
