Affordable, open-source humanoid robot for beginners unveiled in US

Berkeley engineers have introduced the Berkeley Humanoid Lite, an affordable, fully open-source humanoid robot aimed at beginners in robotics. Standing about one meter tall and weighing roughly 35 pounds (16 kilograms), the robot is constructed primarily from 3D-printed parts and off-the-shelf components, keeping the total cost under $5,000. Its modular design includes actuators with durable cycloidal gears that compensate for the lower strength of 3D-printed plastics, enhancing longevity and ease of maintenance. Users can easily source parts online or print replacements themselves, making the platform highly accessible for hobbyists, students, and educators without requiring specialized tools or equipment. The project addresses the common barriers in humanoid robotics, such as high costs and proprietary hardware/software that limit customization and repair. By providing full access to hardware designs, code, and training tools, Berkeley Humanoid Lite empowers users to build, modify, and improve humanoid systems from the ground up. Assembly typically takes about a week for
