Frostpunk Automaton Rigging

Hey! This is my latest rigging project, I've wanted to rig a mechanical prop for a long time so here is my try on Frostpunk automaton. My goal was to create a simple yet complete rig with intuitive controls for each piece, and learn new things like motion path constraints or spring IKs. Hope you enjoy it!
The 3D model (mesh and textures) was made by one ear on Sketchfab, here is the link to it: https://sketchfab.com/3d-models/frostpunk-automatic-machine-3fa4c3363903429fb88627995cb1bb29
