How I Built a 3D Printed Robot Arm from Scratch (Arduino Based)

I made an Arduino based robotic arm with a unique control system for under $60! This video will take you through the design, assembly, and code process. My goal was to design an arm that was as compact as possible and didn’t have a mess of wires coming out of it. I think this arm turned out pretty well!

PLEASE NOTE: These designs and code are FAR from perfect. There are still many improvements that can be made to both. I am just sharing my work with the community as it is, and it may not work for you exactly as it does in the video. This arm will require a lot of soldering, especially for the controller. The arm also requires other small parts that were not mentioned in the video like a few small gears for the last rotational segment of the arm and some extra wires. At the time of designing and recording, I had not planned on making this arm open source. That is why the arm may be difficult to replicate and why it was not explained in great detail.
