I hear they've discontinued that Robo dog, and also the Robo dinosaur that replaced it.

The hot item now is the self-propelled computor-controlled vacuum cleaner. So many people have "hacked" it, that the maker is now providing a "port" on new models so you can connect it to your laptop, and is giving "free guts" to university robotics classes so they can experiment without having to build the drive and steering systems.
