The "Yellow Drum Machine" is a snazzy little hand-made robot which putters around, casting its two-camera head franticly for obstacles, then raps out a short beat on whatever it can put its sticks to. It then records its own beat, loops it, and begins to play along with its own rhythm. It's a one man robot band. It will do great for itself busking in the robot subways, especially if it can hook itself up with a troupe of robot breakdancers.
