On their website Marek Michalowski and Hideki Kozima write, "BeatBots is a project to develop technologies and methodologies for human-robot interaction that incorporate the rhythmic properties of human interactive behavior."
Translation: these guys have created a robot that dances to Spoon. Dances crazy-good, in fact.
(For your convenience here's the YouTube clip, though the dancing is slightly smoother at the above site. Also, these BeatBots should not be confused with Beatbots, an online zine produced by Baltimore & Washington-area pop culture enthusiasts.)
