I want one! Super O would have a blast with this!
Marek Michalowski of Carnegie Mellon University in Pittsburgh, US, and Hideki Kozima of the National Institute of Communications Technology (NICT) in Kyoto, Japan, programmed the squishy, yellow robot, called "Keepon", to pick out the beat in a piece of music and move along in time. It can also track the rhythmic motion of a person or another object and move in time to that. For more info, see Infanoid Project.
(I've never embedded a YouTube! video before. I hope this works!)
