Cut and fold a paper Snailbot, make it crawl by hand, then give it a brain and a muscle. An Obo Play (ESP32) tells an SG90 servo what to do, and a few lines of code make the snail crawl by itself.

This project demonstrates a simple cardboard robotic hand that mimics finger movement using straws and strings. The cardboard forms the hand structure, the straws guide the strings, and pulling the strings bends the fingers like tendons in a real hand. It is a simple way to learn about robotics, joints, and human hand movement.
