I havn't read any of Luc Steels stuff for a long time, but he has been researching the evolution of language using robots or software agents since the early 1990s. This is really a symbol grounding problem where the communication in some way needs to represent things or situations which the agent can perceive with its sensors.
Some years ago I tried to do something similar to Pierre Oudeyers video using a humanoid robot - presenting objects and saying "this is a..." or "what is this?" or "Is this a...?". I didn't go very far down this route because I found that visual recognition of objects constitutes the major part of the problem. It is possible to use SIFT features and geometric hashes (which I think is what the AIBO robot is doing in this demo) but these 2D methods just aren't very good on objects with complicated 3D shapes. Since I'm interested in making machines which are genuinely intelligent, as opposed to appearing to be intelligent in a five minute demo, I've spent most of my efforts on the 3D object recognition problem. It turns out that other things are fundamentally related to this problem, such as mapping, navigation and SLAM.
