Teeny, tiny little remote-control robot with AI

In case you missed this over at BoingBoing.net the other day, you've got to check out this teeny, tiny little remote-control robot!

From the product description:

The World Smallest RC Robot with Artificial Intelligence (AI)!
The all-around control, you may never experience it! The 6 directions control plus 3 speed levels. Also the Robot can be controlled via Artificial Intelligence (AI) after you press the AUTO button, then the Robot can detect-and-escape from the barriers. What's more, after you press the AUTO button and Direction button, the Robot can detect-and-trace the objects. In the Trace mode, the Robot can be charged and run to the controller automatically! The controller as a Robot Station can be stored a Robot inside.

Here's a link to the product page with more images, varieties, and a somewhat hyper-active video of The World Smallest RC Robot with Artificial Intelligence.
