Sony UK has an interesting article about Aibo Mind 3 software. There's also a mention of Aibo's new location memory that allows it to remember where it has been and where important items, such as it's charging station and toys, are located.
Another benefit of the location memory is that Aibo can quickly and accurately move from location to location. And I do mean quickly - if the Aibos I saw scuttling around the Sony offices in Brussels earlier this week are anything to go by.
