But the question remains about filling it. I think we want a robot brain that can go above and beyond the basics. The basics include vision, obstacle avoidance, beeping, moving in some patterns, determining location and orientation, sumo, maze solving, wandering, not falling off a ledge, ranging, mapping, accepting input from sensors, recharge batteries when necessary, and other fundamental age proven activities. Therefore the purpose of a brain beyond the basics would include thinking, reasoning, and the ability to resolve problems and accept new challenges.
