The Annin Robotics AR2 and AR3 are free open plan low cost robots anyone can make themselves. They can be made using aluminum components or you can 3D print the parts yourself.

The AR2 robot was the initial release of this robot and is the open loop version, The AR3 is the next generation and is identical to the AR2 with the exceptions of being closed loop (encoders) and having updated covers & spaces as well as an updated wiring harness.

The 3D print files, operating software and assembly manuals can all be found on our downloads page for free.

Aluminum parts and hardware kits are available

on our kits page.

The goal of the AR2 and AR3 was to create a low cost option so that anyone could build a 6 axis robot for fun, educational purposes or small production operations.

My goal is to continue improving the software and functionality and provide the lowest cost solution for a 6 axis robot that can actually be used for real tasks.
