Crazy drum robot
This is what you get when you add two drumsticks to your robot - one crazy machine that drivers around the house, plays drums and dances around.
All jokes aside, if that is possible, this robot has some sort of brain. It is capable of learning a rythm and reproducing it. Also at the end of the video there is a single-drumstick robot that plays on it's first obstacle. Don't miss the end of the video because that part is the funniest.
