AI Sapiens K0

The AI Sapiens K0 by ROBOTIS is an open-source humanoid platform optimized for physical AI research, standing 1.3 meters tall with 23 degrees of freedom for full-body dynamic motion. Powered by advanced DYNAMIXEL-Q quasi-direct drive actuators like QM-060 and QM-080, it excels in bipedal locomotion, precise manipulation, and real-world interaction, bridging simulation-to-reality gaps via imitation and reinforcement learning. Each arm supports up to 3 kg payloads, enabling tasks like object grasping and handling in contact-rich environments. Its lightweight 34 kg frame enhances safety for human-robot collaboration, while fully open hardware and software stacks—including simulation tools and training artifacts—empower researchers, educators, and developers to customize, train policies, and deploy adaptive behaviors for locomotion, manipulation, and human-robot interaction in research settings.
