How about a robot that would tune your guitar for you?
Basically here's how it could maybe work:
1: strike string 1
2: listen to (Hz of) note with a mic
3: move the turning pegs with another robot
4: repeat step 3 until string is in tune
5: repeat all for string 2, then 3, etc etc
just an idea I had when tuning my guitar and noticed the little Hz indicator on the bottom of the tuner i use. I think it'd be pretty cool :3
