It looks more like R2D2 or a Dalek than Wall-E to me. The part that I find especially interesting is how they get different behavioral patterns – personalities if you will – from each of the several different brain units that they use with the robot. It’s hardly surprising given the biological nature of the neuron-brain units, but I still find it interesting.
I don’t suppose little rat-brained robots would make practical pets yet. 😦
