Vietnamese robot manufacturer Tosy Robotics - maker of the Ping Pong playing TOPIO - has a small slate of goods at CES this year, but both are pretty neat, if lacking in any practical utility. Take this clever dancing robot. It dances rhythmically, in time to whatever music you happen to play. In this case (though you'll have to strain your ears to hear it), it's Michael Jackson's "Billie Jean". Thankfully, they didn't demonstrate using Dubstep, but presumably it would find a way to locate a rhythm. Though the date is still TBD, this bot is due to become available in North America sometime in early Q2.
