Artificial Arm – Build a Real Robotic Artificial Arm | Arctos Robotics

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.

Frequently Asked Questions About Artificial Arms

In robotics, an artificial arm is a programmable, multi-jointed mechanical device replicating the structure of a human arm. Motors drive each joint, and firmware plus software coordinate motion across multiple axes to achieve precise, repeatable 3D movement for automation, research, and education.
Yes. The Arctos is designed for home assembly. With a 3D printer, the hardware kit from $231, and 15–25 hours of build time, you’ll have a fully functional 6-axis artificial arm. The full assembly manual, wiring guides, and Discord community of 1,200+ builders support every step.
A prosthetic arm is a medical device worn by a person to replace a missing limb. A robotic artificial arm like the Arctos is an electromechanical system mounted on a fixture and controlled by software — designed for automation, research, and manufacturing rather than personal rehabilitation.
The v2 closed-loop kit uses magnetic encoders on every motor shaft for continuous position feedback and drift correction. Arctos Studio’s digital twin syncs with the physical arm at under 10ms latency, enabling accurate path programming for pick-and-place, welding simulation, and 3D printing automation.
Arctos Studio — a free professional robot simulation app — handles the arm. It includes AI object recognition, PLC programming, reinforcement learning, digital twin simulation, and offline programming for KUKA, ABB, FANUC, UR, and more. A Pro lifetime licence is €99. All firmware is open-source on GitHub with full ROS/ROS2 support.
The open-loop kit is beginner-rated (~15 hours). You need intermediate 3D printing skills, basic soldering, and patience for small mechanical assembly. The closed-loop kit is intermediate (~20 hours, encoder configuration required).
