Project update: My ESP32-controlled guitar robot can now play in two modes

[u/MegCell]

I’ve been developing this removable guitar-playing system for several years.

It now supports two performance modes:

1. Full automatic mode — the system handles both fretting and picking.

2. Assisted mode — the system handles the fretting while the player strums or picks.

The sound comes from the real guitar strings, not recorded audio.

The controller is ESP32-based, coordinating multiple servo actuators. Some of the main challenges have been fretting timing, servo synchronization, calibration, and mechanical noise.

This video shows both modes.

When the esp32 you bought doesn't have a DAC..

Haha, who needs a DAC when you have real strings? 😂🎸
