More than 300 humanoid robots competed in China's second robot half-marathon in Beijing on April 19, 2025 [1, 4].
The event serves as a critical benchmark for the robotics industry, testing the real-world viability of embodied AI and battery endurance over a long distance. By pushing machines through a 21-km course, developers can identify failures in autonomous navigation and physical stability that laboratory settings cannot replicate.
About 70 teams participated in the race [2], including entries from major technology firms such as Alibaba, Honor, and Unitree [1]. The competition focused on three primary technical pillars: autonomous navigation, battery life, and the integration of embodied AI [1, 2].
According to available data, nearly 40% of the participating robots utilized autonomous navigation systems [2]. This represents a significant shift toward independence from human remote-control operators, a necessary step for the deployment of robots in urban environments.
The race took place at the E-Town venue in Beijing [1, 3]. Organizers said the event was designed to showcase the latest technical leaps in the field and demonstrate how humanoid forms can handle the stresses of sustained movement [1, 2].
While some reports initially suggested a smaller field of over 100 robots, the final count exceeded 300 machines [1]. The event highlights China's aggressive push to lead the global humanoid robotics market through large-scale public demonstrations of hardware and software synergy [1, 2].
“More than 300 humanoid robots competed in China's second robot half-marathon.”
The transition from controlled laboratory environments to a 21-km public course indicates that humanoid robotics is moving from the proof-of-concept stage to endurance testing. The high participation of corporate giants like Alibaba and Unitree suggests that these companies are pivoting toward 'embodied AI,' where intelligence is integrated into physical forms capable of navigating complex, real-world terrains.
