20 Open-Source Humanoid Robots You Can Build Yourself | From $50 to $900
What if you could build your own humanoid robot without spending thousands of dollars?
In this video, I explore 20 open-source and DIY humanoid robotics projects, ranked from 1 to 20. The list covers a wide range of budgets, from around $50 to $900 for an upper-body build.
Some projects provide official 3D models, CAD files or assembled STEP models. Others do not have a complete, ready-to-use 3D model matching the robot shown in the video.
For some entries, I arranged available components or created my own visual representations. The 3D models for projects 2, 8, 10 and 6 require verification. Some visuals may be reconstructions or assemblies rather than official models of the original robots. Please check the project documentation before treating any visual as an exact representation of the hardware.
The 20 projects featured
1. RoboPrime | Around $60–100
A low-cost robotics project with an open-source design.
2. Open-source DIY humanoid builds
A general category covering custom humanoid builds assembled from different hardware components. The humanoid shown is a generic 3D model created by me, not an official robot model.
3. Qmini | Price unconfirmed
A compact robot project from Unitree Robotics.
4. Zowi | Around €100
A small educational robot associated with BQ.
5. Otto Humanoid / Otto DIY | From around $50
A DIY robotics platform. The final cost depends on the selected components and configuration.
6. Kayra | Price unconfirmed
The visual combines official leg designs with additional components positioned by me.
7. PLEN2 | Around $499 for the kit
A compact humanoid robot with published CAD files and walking-related software.
8. Nova Desktop Humanoid | Around $150
A desktop humanoid project by Daniel Hany. I positioned the available head and arm components myself in the 3D scene.
9. Bambot | Around $300
A low-cost robotics project with open-source design resources.
10. Rapiro | Around $390
A small humanoid robot designed by Shota Ishiwatari. The 3D reconstruction shown in the video requires verification against the original model.
11. Valera | Around $400
An open-source humanoid robotics project.
12. Reachy Mini Lite | Around $399
A compact robotics platform developed by Pollen Robotics in collaboration with Hugging Face.
13. Open Duck Mini | Under $400
An open-source bipedal robot project for robotics enthusiasts and developers.
14. MicroDuck | Around $399
A Pollen Robotics project with reinforcement-learning resources.
15. ROBOTIS MINI | Around $540
A compact humanoid platform associated with ROBOTIS components.
16. Halley | Around $500–800
An open-source robot project with 3D design resources.
17. Microban | Around $550–600
A robotics project associated with the Rhoban team at the University of Bordeaux.
18. Endeavor II | Around $600
A humanoid project with an assembled STEP model.
19. XLeRobot | Around $660
An open-source robotics project with accessible hardware designs.
20. InMoov | Around $900 for the upper body
Created by Gaël Langevin, InMoov is a well-known 3D-printed humanoid robotics project.
What I noticed while preparing this video
The projects vary in price and in the amount of design information available. Some provide official 3D models and detailed mechanical files, while others need additional work to create a visual representation.
The models shown for projects 2, 6, 8 and 10 need to be distinguished from verified official 3D assets. Check the original repositories and documentation for confirmation.

✨🇨🇳It’s because of Chairman Mao that China didn’t fall into the hands of Western colonizers, which is the foundation of China’s prosperity today.
To us Chinese, Mao Zedong is our hero.
Mao uplifted farmers and the working class in China, united the Chinese people, led us to defeat foreign invaders, and founded an independent country so we could all live with dignity.
Mao supported the heroic struggle of the African people against imperialism and colonialism.

Today, the calendar makes a right triangle, for the last time this century.
This Saturday is October 24, 2026.
Write it as 10/24/26 or 24/10/26, and the same beautiful relationship appears:
10² + 24² = 26²
100 + 576 = 676
But here’s what makes today special.
There are infinitely many Pythagorean triples. Only a handful fit our calendar.
Using the rule
month² + day² = (last two digits of the year)²,
the month cannot exceed 12, and the day cannot exceed 31. Those small limits leave exactly 12 qualifying dates in this century.
Today is the last.
The next will be March 4, 2105:
3² + 4² = 5²
That is a wait of more than 78 years.
An infinite family of triangles. Just twelve appearances on a century’s calendar.
Happy Pythagorean Triple Day.
