"Notice how the robot first plays on the object it finds (or is forced to find by the angry cameraman), plays a small beat, and records the beat it plays on it. Then this recorded beat is played again, and it starts to play on the object (an belt tracks and everything else it has),and also playing this sampled beat," says Let's Make Robots!, introducing the Yellow Drum Machine build-it-yourself project.
Let's Make Robots! has videos.
