Humanoid Robot Half Marathon Champions: Tiangong Ultra, Songyan Power N2, Walker 2

April 19th, 2025 Beijing YizhuangHumanoid Robothalf marathonThe results of the race are now official: "Tiangong Ultra" from Yizhuang, Beijing, crossed the line in 2 hours, 40 minutes and 42 seconds to win the world's first half-marathon for a humanoid robot. The 1.2 meter tallSongyan Power N2 Little Naughty Boysfinished second, with Shanghai'sWalker II Robotics TeamFinished third.

The 1AI summarizes the above battle profiles:

• Team Tiangong (Tiangong Ultra, height 180cm, weight 52kg):Measured average speed of up to 10km/h, the highest running speed has been raised to the world's leading 12km/h, and can move smoothly in a variety of terrain such as slopes, stairs, grass, gravel, sand, etc., with a visual sense of the generalization of the ability to move, can easily deal with the gullies, large height difference and other complex terrain, and has a strong anti-jamming ability, by the impact of the external forces can still maintain a steady state.
• Little Naughty Boys (Little Naughty Boys N2, height 1.2m, weight 30kg):With the core concept of "anthropomorphism and running", the robot focuses on mimicking the flexibility and coordination of human's natural gait, and through biomechanics-inspired design, the N2 robot is given a running posture closer to that of a human being. By combining joint elasticity drive and dynamic center of gravity adjustment technology, the team realizes efficient energy recovery and adaptive gait switching in complex terrains, enabling the robot to jump and sprint steadily at the same time.
• Team Walker II (Walker II, weight 28kg):The first footed robot in history to exceed 100 kilometers of walking distance, with a range of more than 6 hours, using high-strength, lightweight composite materials to reduce weight and ensure structural strength.
