China’s robotics firm Unitree has pushed humanoid mobility forward. In a public demo video, its full-size biped H1 reached a top speed of about 12 km/h, a mark that made it the fastest known humanoid robot at the time. The same video shows H1 walking quickly, climbing stairs, hopping, and recovering balance after pushes, which points to strong control of whole-body motion in real time.
H1 is built as a general-purpose platform, close to human size, with high-torque joints and 360 degree perception from a 3D LiDAR and a depth camera. These sensors let the robot understand its surroundings in real time, which supports stable foot placement and fast gait changes on varied ground.
The speed claim matters for more than races. Higher stable speed suggests better energy use, better balance control, and more headroom to handle real-world disruptions. It also shows that the same hardware can switch between agility demos and practical tasks like carrying objects or moving through industrial sites.
The humanoid field is crowded. Boston Dynamics and Agility Robotics lead on dynamic moves and logistics pilots. Oregon State University’s Cassie, a leg-only robot, holds the 100-meter biped record, but it is not a full humanoid. Unitree is targeting researchers and companies with pricing around the low six figures, which lowers the barrier to trial programs in labs and factories.
Since the H1 video, the pace has kept rising. In late 2024, China’s Robot Era showed a humanoid named STAR1 jogging at a slightly higher top speed on outdoor terrain, helped by sneakers. Even with that update, H1 remains a reference point for fast, stable motion in a human-sized package, and it illustrates how quickly humanoid locomotion is improving.
