Last week, I got a visual prototype together of how a drumming robot should wield a stick. FROM THE WRIST! #BatmanMeme Most drumbots just pull the stick down to "deadhit" the skin. There's a lot of work to do on that part of this project, but meanwhile, there's also some basic electronics to prove the concept.

A drumbot needs a motor to flick the stick, then pull the stick quickly, but gently, back to rest and hold it there. It also needs to read MIDI note velocity and map that to the motor's useful powerband. Finally, the motor has to quickly and quietly restore the stick to its ready position.

All this requires complex motor control, Pulse Width Modulation (PWM) to be exact, and a microcontroller to read the MIDI Note-On data and have each part of drumbot respond appropriately.

Circuitry and basic code are proven. I'll probably end up blowing up 4, VERY expensive MOSFETs in my first attempt, but hey, we're on this earth to make mistakes, and thereby make the future. This is not a cheap project, either, and is third in my project queue, so it will take some time.
