Guess how much it costs to build your own bipedal robot.
Hugging Face's LeRobot team has open sourced a two legged robot designed for locomotion research.
Here's what you get:
• 12 degrees of freedom, 6 per leg
• 75 3D-printed PLA+ parts
• Around 3.5 kg of filament
• Raspberry Pi 5 and an onboard IMU
• 12 RobStride actuators communicating over CAN FD
• Public CAD files, assembly guide and MuJoCo simulation tools
Estimated hardware cost: $2,600, excluding shipping, taxes and import duties. The actuators alone cost around $1,900.
I like that you can test walking policies in MuJoCo before printing and assembling the robot. That gives researchers a way to work on locomotion in simulation before moving to physical hardware.
It's a biped designed for locomotion research, not a complete humanoid with arms and a torso.
Would you build one for $2,600 or start by testing walking policies in simulation?
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.

뱀부랩의 AMS처럼 Prusa에는 여러 필라멘트를 한번에 보관하는 기기가 없나 했는데 공식도 비공식도 아닌 INBXX라는 게 있다. 능동 가열로 습도 유지하는 구성도 가능한데, 완제품이 아닌 키트 형태. printables.com/model/1411246…
