Arduino Programmable Foldable Worm robot

My plan was to make a mini or micro size robot. But I still can't afford a 3D printer so I could not scale it to that mini size, still this robot looks cool and hels up understand worm behavior and creates interest in robotics.

Right now it can fold, unfold and walk by itself. My plan is to add sensors and give it the capability to go left right and backward.

This is a project I am still working on, here's a heads up of what I've been doing. Codes and Schematic will be uploaded soon.
