Smartphone-Controlled Desk Pet Tankbot
Come on -- who wouldn't want one of these things? The Tankbot from Desk Pets transforms your smartphone into a wireless command center for a tiny, feisty robot. All you do is plug an attachment into your phone's headphone jack, install a special Desk Pet control app and then drive, baby, drive.
If you don't feel like controlling the Tankbot yourself, you can activate autopilot with its touchless navigation or "autonomous personality" mode. The gizmo even includes "advanced optical navigation technology" to keep it from running into objects when left to its own devices.
