LAS VEGAS -- In the video above, we go hands-on with the Sphero 2B -- a quirky phone-controlled robot. Hit play now to check it out.

2B or not 2B

The 2B is the sequel to the Sphero -- a basic remote-control sphere that hurls itself around your floor. The follow-up adds bulky customisable wheels, and communicates with your smartphone via an iOS or Android app, plus the power of Bluetooth 4.0.

If you get two 2Bs together, maker Orbotix says you'll be able to make them fight -- shooting virtual lasers from the glowing logo on the front. Orbotix says to expect the 2B to be on shop shelves this holiday season, priced at $99.

Would you be happy to see the 2B rolling around your living-room floor? Let me know in the comments.
