Investigating one particularly crowded booth today at 2012 International CES revealed that some were there for Tosy Robotics JSC’s new dancing robot, while the squealing others were there to see pop sensation Justin Bieber. Judging by their behavior, you’d never know everyone was at a trade-only show.

To his credit, Bieber had added the hashtag #gadgetNERD when he tweeted his CES visit to his millions of fans.

The robot is Tosy’s mRobo Ultra Bass, which sits looking like a regular portable speaker until it hears music. Then it unfolds as though growing a head, legs and arms, and begins dancing its pre-programmed routine of dance moves in time with the tunes. Alternatively, it can store 2 GB of music for playback through its integrated speaker. Its belly bass only goes down to 40 Hz, but that’s too not bad for a $199 transforming, dancing robot that comes with a remote control. Weighing approximately 3.3 pounds, mRobo stands slightly under 18 inches tall when dancing.

Ho Vinh Hoang, founder and chief executive officer, Tosy Robotics JSC, was thrilled to share a stage with Bieber and the mRobo. “It gives music and dance lovers the ability to enjoy their passions in a whole new way. Not only do they have a great new way to listen to their favorite songs but they also have a new partner to dance to their favorite music with,” he said, referring to mRobo.
