OZOBOT at CES
Of all the robots featured this year at CES, the smallest I saw was the OZOBOT. Launched as "the intelligent game piece for digital and physical play", the OZOBOT comes with a variety of features for on tablet and off tablet play. It is able to follow lines, distinguish colors, vary its speed along a path, communicate with you and make descisions for the ultimate robotic game action. If you want to see more of the OZOBOT in motion, CNN has great video coverage of it here.
