How to build a robotic arm yourself. In this tutorial you'll get full detailed instructions on the build. I did this completely myself in order to learn something new and explore places I haven't been. I hope that you'll enjoy building it as much as I did.

I made a step-by-step assembly manual and CAD files available all in one website. Also there is a forum and other tutorials at this link:

Schematics, diagrams and documents


Made by easyeda showing microporcessor, shields and drivers connected to the stepper motors

CAD, enclosures and custom parts

CAD files

Rough cad files showing just the outter body, used mostly for simulation. Full CAD files available here


Arctos GRBL firmware

Heavily modified grbl firmware compatible for this custom kinematics
