TankBot under your wing. Desk Pets' palm-sized four-wheeler first whirred into our hands earlier this year at the International Toy Fair, promising a variety of play modes and iOS control. Now, the team behind the roving gizmo has finally released it to retailers' shelves, tacking on a $25 price tag and adding Android compatibility. The mini-bot operates in a trio of configurations: an autonomous mode that makes use of its infrared sensors to navigate obstacles, a free-roaming option that'll have it wandering aimlessly and, most importantly, a free mobile app that puts dual joystick control on your Apple device's screen or universal remote (connected via headphone jack) for steering on an Android phone. Don't expect to squeeze hours of fun out of this little tchotchke, though, as its retractable USB port only gets you about 15 minutes of gee whizzery. Skip past the break to watch a video demo of the lil' guy en vivo.
