Artificial Arm. Built By You.
The most complete DIY artificial arm ever made. 3D-printed, open-source, AI-powered — and running on your desk for as little as $231.
A robotic artificial arm — the closest thing to a human arm, engineered from scratch.
“The same architecture powering factory robots — now printable and buildable at your desk for $231.”
An artificial arm in robotics is a programmable, multi-jointed mechanical system that replicates the kinematic structure of a human arm. Each joint is driven by a motor, giving the arm precise, repeatable movement across multiple axes — enabling it to reach, rotate, pick, place, weld, or trace almost any spatial path.
Unlike fixed automation machinery, an artificial arm is inherently flexible. The same arm can sort components off a conveyor belt one day and follow a complex welding path the next — without changing hardware. This adaptability is why robotic artificial arms sit at the heart of modern industrial automation, academic research, and maker projects.
The Arctos artificial arm brings this technology to your desktop. Built from 168 3D-printed PLA parts, off-the-shelf hardware, and open-source firmware, it delivers genuine 6-axis motion — the same fundamental architecture as industrial arms costing tens of thousands of dollars — at a fraction of the price. Arctos Studio, the included free AI software, lets you program and simulate the arm exactly the way a professional robotics engineer would.
Whether you’re a student, a maker, or an engineer prototyping automation concepts, the Arctos artificial arm gives you a real, capable platform to build on.
