It’s a sad state of affairs when a company creates a commercial with a human competing for a top dance spot with a robotic device. Remember Miuro? Sony has devised its own dancing bot to be released in the States sometime this spring. Palm-size, Rolly uses the reflection of the floor to create an acoustical image, with speakers at 180º angles. Considering how identically the two bots operate, it might be a better alternative to pit them against each other.
