Tendon-driven linkage

# Simple Robot tendon-driven linkage

A low-friction, easily printable joint designed for robot arm applications.

## Overview
This joint provides a simple, robust solution for robotic movement. It is designed to be easily 3D printed and assembled with minimal hardware.

## Parts Needed
* **1x** 3D printed joint assembly
* **1x** 30mm M3 bolt
* **1x** M3 nut
* **2mm** Kevlar string

## Printing & Assembly
* **Material:** Printed using PLA, though most rigid materials (PETG, ABS, etc.) should work well.
* **Assembly:** Simply align the joint pieces, secure with the M3 bolt and nut, and thread the 2mm Kevlar string through the designated channels to facilitate movement.
