Remember Sphero? You will after you watch this awesome video showing it being used with the Sphero Golf app. Sphero is a robotic, smartphone-controlled orb. We first saw Sphero back in December, and then got to see it in action at CES 2011. Measuring in at 2.9 inches in diameter, this omni-directional spherical roller-bot is Bluetooth-controlled, induction-charged, and compatible with both iOS and Android devices. Also cool: there’s an open API so developers can write their own apps that work with the nifty gadget. It’s a little difficult to actually see Sphero Golf in action in the video since it’s shot at night, but the plethora of glow bracelets, glow glasses, and glow hats, paired with some seriously dance upbeat tunes, make it exciting nonetheless. Sphero is set to be priced at $130, and a purchase will include the Sphero orb, Sphero Golf, and two other apps. A handful of other Sphero-based games will also be available at launch on the Apple App Store and Android Market. Although it won’t be available for purchase until late 2011, if you already know you definitely want one of these Bluetooth-controlled balls, you can reserve one today.
