Justin Bieber teamed up with Vietnamese electronics company TOSY to help it unveil its latest product, the mRobo Ultra Bass, at CES 2012.

As expected, The Biebs drew a huge crowd, and despite some technical difficulties, the 17-year-old successfully showed off the mRobo, a portable speaker that transforms into a robot and can dance to the beat of your music.

Justin graciously took photos with fans for an hour, and was all smiles at the event, wearing a Louis Vuitton leather-and-denim jacket. The amount of money Bieber earned from the appearance has not yet been disclosed.

According to Slash Gear, the mRobo can store 2GB of music or around 500 songs, but the dance moves are pre-programmed and operated by remote. The robot speaker will be available for purchase for $199 this fall, but we have a hunch Justin already has one at his home.
