There were rumors on the Rolly crawling the internet for a while now, and today Sony finally unveils the truth about this new robotic toy, the ROLLY.

Essentially the ROLLY is a kind of wireless speaker/audio player with 1GB of internal memory, you can interact with it and select the tracks you want to listen to. The Rolly is an autonomous audio player which can playing MP3, ATRAC, or AAC tunes and has a battery life of 5h when it plays music from its internal memory and 4h 30m if the music it streamed to the ROLLY via Bluetooth computer connection.
