- Worth noticing
- The robot uses a homing sensor, belt-driven carriage, and solenoid striker; the piano-light guide is still shown as a render.
Field notes
The build notes describe how the carriage finds position zero with an inductive sensor, then uses counted stepper movements to line the striker up with each bottle. The page names specific components, including an ESP32 and a JF-1039B push-pull solenoid. Its pianist-side light guide is not yet shown as physical hardware: the author labels the images as sketches or renders.
