Thank you for watching this video, please leave a like or a comment. I do appreciate constructive feedback, positive and negative.

Disclaimer: I am a firm believer in “Betteridge's Law of Headlines” and I do know that this robot is not better than humans ;-) because right now, the sound is harsh and the servos are annoying. Also, since the notes are always played with the same loudness, a lot of finesse gets lost that a human player could bring to the table. But I still think this is a pretty cool proof of concept for what it is, some 3D printed parts, electronics and a few thousand lines of code….

On another note, tell me which song these robots should play next. I'll produce a few YouTube shorts with more music and less talking.
