Dancing Robot Travis

Is this a robot or a moving speaker? Travis  is an better version of the Shimi. It is able to select songs from a library based on the rhythmic input.

This is not the only dancing robot around but another way to introduce robot technology to the real work through different mediums. Speakers docks are very popular given that most people own at least 1 smart phones. This reminds me a lot of the Sony Rolly.
