Here’s a concise summary of the news article:

Researchers at Berkeley have developed “Berkley Humanoid Lite,” an open-source, 3D-printed humanoid robot designed to democratize the field of humanoid robotics. The robot, costing under $5,000 thanks to readily available parts and a cycloidal gear design, emphasizes accessibility and customization. Researchers validated its performance through experiments like solving a Rubik’s Cube and developing a locomotion controller using reinforcement learning, demonstrating zero-shot policy transfer. They’ve introduced a performance metric – the “performance factor per dollar” – to quantify its cost-effectiveness, highlighting its impressive capabilities relative to its low price. The project is supported by an open-source community and readily available resources.
