Overview
I designed and built a 6-axis robot arm that picks up coloured blocks and sorts them into zones. I use it to research PID control loops and machine learning for robotics.

Build
The arm is 3D printed and driven by servos through a custom controller. I developed it in stages, from a breadboard servo rig to a full arm on a test board, and fixed mechanical and electrical problems at each step.

Control & Vision
A machine-learning computer vision system finds each block and its colour. PID control drives each joint to its target, so the arm moves accurately and repeats its moves reliably.
