Build the Future
With Your Own Hands.
Learn Like an Engineer.
An open-source, 3D-printed robotic arm powered by Arduino ESP32 — designed for classrooms, universities, and maker spaces. Real kinematics, real code, real engineering.
Theory Without Practice
Doesn't Create Engineers
STEM education needs real tools. Our platform delivers them — affordably and openly.
The Problem in Education
Standard STEM curricula are too theoretical. Students write code on screens but never see a physical result. Industrial robots cost a fortune and educational kits are oversimplified toys.
- Students write code but never see it move a real mechanism
- Industrial robots cost $25,000–$150,000+
- Educational kits are simplified toys with no real engineering value
- No connection between mechanics, electronics, and software in class
- Fear of breaking things limits hands-on experience
The UMX Solution
A real kinematic robot that students assemble, wire, and program themselves. Break a part? Just 3D-print a new one.
- Affordable — a robot for every workstation is possible
- Broken part? 3D-print a replacement in hours, not weeks
- Program in C++ & MicroPython — real languages, not blocks
- Integrates mechanics, electronics, and software in one project
- WiFi control & open source — endless project possibilities
