Amazing drum machine robot

Submitted by on June 23, 2010 – 8:33 pm 2 Comments

I love drum machines – from the boooom of the tr808 to the snappy kick of the tr909, to all the weird an wonderful sounds from early analogue boxes. Well, here’s a completely different kind of drum machine, the little yellow drum machine.

As part of a project for a promotional contest to Audiofile Engineering, Frits Lyneborg from Copenhagen, Denmark created a DIY robot that runs around looking for things to drum on, then samples an plays back its beats.

The robot searches around it’s surroundings until it finds an object that is “worth playing on” (a single isolated object or a wide flat surface that it can find an angle onto).   It then  plays a beat on the object with it’s 2 drumsticks (and “bass drum” stick underneath) and records what it plays. If it decides that it sounds good, it’ll loop this sample and play along with it.

What was Frits’ inspiration for building this drummer robot? He says:

Well.. I was sitting thinking what I should do for my next robot, what it should do.. Listening to music.. making a rythm with some robot-parts.. Thought; “Hey, I will make a robot that drives around and plays on stuff”

Fair enough.

On the bottom is a speaker and a microphone. The speaker makes beeps from the controller chip, and also makes clicky-type sounds to the beat of the rhythm.

The microphone (located on the stick between the two motors) is used to sample sounds, measuring if the sticks are hitting anything or not while it’s playing.

Another cool feature is that it can detect when you are clapping your hands or stomping your feet, and play along in time to your beat. It’ll also sample your shouting or other noises and incorporate that into the beat as well.

At the top there is another speaker, which plays the loop, along with an LED that flashes to the beat when it’s recording.

How awesome is that? Here are some videos of version 2 in action:
