Here’s an interesting concept from one of Japan’s leading telecommunication providers, the Polaris. KDDI, in corporation with Japan’s Flower Robotics, have built what very well might be Roomba meets cell phone meets Loopt…and then some. The phone itself doesn’t sound all that mind bendingly crazy, but toss it into the docking system, which includes a set of speakers, and the on board motor will fire up the wheels and drive it to its closest power source once its juice runs low.
Using what is probably a combination of GPS and NFC (near field communication) the phone tracks where you went and what you bought. Connect it to a near by TV or monitor and the data can be displayed in a somewhat digestible format.
They plan on having a commercial version of the Polaris by sometime next year.
