PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
This is a 3D Printable Robot Arm. It may need a bit more time to build one, than your normal weekend Project. But the build process is one thing, the application environment the other. And that is what it is all about. Learning, combining and developing custom applications.

=========
There are a few community driven derivations and projects around, so check them out!
* Some useful derivations such as end switches and a belt drive can improve your RobotArm build.
* 20sffactory has created a support group on Facebook https://www.facebook.com/groups/828749637471209
* 20sffactory has also a python voice control Project, check it out on Github https://github.com/20sffactory/voicebot_opensource
* Aaron Huang pointed out some errors in the inverse kinematics: https://github.com/AaronHuang1228/Question-for-RobotArm Code and Documentation updated accordingly

Hardware
========
The design goal for me was to build a Robot, which is stiff and strong, but still small and easy to handle. I used the common NEMA17 Step Motors, which provide enough power for fast movements and high precision.
Almost every moveable joint has at least one ball bearing to reduce friction, overall stability and accuracy. The robot is designed to have a low center of mass.
The robot is powered over a Computer Power Supply (12V).
The gripper is…
