The SE01 is dedicated to being the most human-like general-purpose humanoid AI Hardware. It features a set of self-developed harmonic joint module and combines reinforcement learning with imitation learning, achieving unprecedented excellence in natural gait through end-to-end neural network models. The design of the SE01 narrows the gap between humanoid robotics and humans, making the robot more agile. With smooth, swift, and graceful walking, the SE01 leaves behind the stereotypical unnatural gait of past robots. Our relentless pursuit of technical excellence at EngineAI is set to establish new industry standards.
