The University of Tokyo has taught their PR2 to fetch a sandwich. If one is not available in the fridge, he goes to the Subway in another building. The bot is using "semantic search," the ability to use common sense when seeking an object. It can also add to the knowledge as it gains more experience. So, although he did have a bit of a bind at the elevator, we still call this a $5 footlong success.
