A new open-source humanoid robot, the Berkeley Humanoid Lite, has been introduced by the University of California, Berkeley, offering an affordable and fully customizable solution for robotics research and experimentation. Designed to be accessible to educators, researchers, and hobbyists, this platform stands out for its modular design, use of low-cost materials, and emphasis on community-driven development.
Unlike traditional commercial humanoid robots, with prices that can often reach six figures, the Berkeley Humanoid Lite can be assembled for under $5,000 using standard components and a 3D printer. Nearly all of its structural elements are printable using a printer with a build volume of just 200 x 200 x 200 mm. The remaining non-printable parts, such as certain fasteners and electronics, are easily sourced from common online suppliers, according to the Paper.
The robot features motorized joints powered by 3D-printed cycloidal gearboxes—a type of high-efficiency drive system favored for its high torque output and compact form. Cycloidal drives are well-suited to the demands of dynamic humanoid motion and are commonly used in industrial automation and robotic arms. Berkeley’s researchers selected this design specifically to offset the mechanical limitations of plastic components, offering a balance of cost and durability, According to Techneblog.
Standing approximately 0.8 meters tall and weighing 16 kilograms, the robot is capable of basic locomotion, including walking and hopping. It also supports reinforcement learning-based motion control, enabling advanced experimentation in simulated and real-world environments.
All design files, source code, and training resources are publicly available via the project’s GitHub repository. The platform includes detailed documentation, CAD models, and ready-to-use control frameworks, enabling widespread adoption and adaptation.
Berkeley Humanoid Lite aspires to democratize humanoid robotics, reducing the barrier to entry for humanoid research and development. By opening up both hardware and software, the project invites global collaboration and aims to accelerate innovation in the robotics field.
