Awake the inner child in your dad with Sphero 2.0 ($99.99), a remote-controlled robot the likes of which your dad never saw while raising you. (Not that he’d have had time for a robot anyway.) The robotic sphere pairs with your iOS or Android device via Bluetooth and careens around at speeds of up to 7 feet per second, with a 100-foot range. The Sphero 2.0 is waterproof, and is recharged by an included induction charger. Since its release, the catalog of Sphero-compatible games and apps have grown to some 30 titles and counting, allowing for many more hours of fun.
