This completely changes how robots can learn in simulation. NVIDIA just launched SimReady Central with 3,500+ simulation ready OpenUSD assets free and ungated on Hugging Face. ➝ Robot arms grippers hospital equipment warehouse gear kitchens. Lightwheel is the largest contributor to the library. Its assets are physics validated with measured mass and inertia tuned collision geometry and joint limits that hold under contact. These are more than pretty meshes. ➝ A robot in simulation learns from how objects collide how heavy they are what moves and how far. If an object looks right but behaves wrong it teaches the policy the wrong lesson.

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.
