It features full-stack proprietary actuator design with integrated joint modules delivering 145 N·m peak torque and 130 N·m/kg peak torque density. The waist rotates over 300 degrees, enabling complex movements including being the world’s first humanoid to perform a forward somersault. It walks at over 2 m/s with nearly 2 hours of battery life from a 10,000 mAh quick-release smart battery. Available in Business and Education editions, the latter adding an NVIDIA Jetson Orin NX, two depth cameras, and secondary development support. An interactive core display and signature star ring light provide multi-dimensional interaction. Open-source training and deployment code repositories support reinforcement learning and deep learning for research and generalist applications.
