RC Excavator Controls

I’m curious how much of a full-size excavator’s controls could carry over to a small RC machine.

Idea
A side-view concept drawing of a tracked excavator with its boom and bucket labeled.
A concept sketch for naming the moving parts before assigning inputs.

What should each joystick movement do?

The part that interests me is the mapping between the operator’s hands and the machine. I want to work that out before picking hardware or building a prototype.

Open questions

  • How should the joysticks map to the boom, stick, and bucket?
  • Which actuators could produce the movements at this scale?
  • How could I test one motion safely before combining the controls?
