Humanoid Robot Half-Marathon Kicks Off in Beijing: A Historic Sprint into the Future

 Introduction

On April 19, 2025, Beijing’s Yizhuang District made history by hosting the world’s first humanoid robot half-marathon. In a groundbreaking fusion of technology and athletics, 12,000 human runners raced alongside 21 teams of humanoid robots, covering 21.0975 kilometers. This event not only showcased advancements in robotics but also redefined human-machine collaboration in sports.

Event Overview

The Human-Robot Half-Marathon marked a milestone in robotics and athletic innovation. Organized to test the endurance, agility, and real-world adaptability of humanoid robots, the race featured cutting-edge machines from universities, research institutes, and tech enterprises across China. Key highlights include:

• Mixed Participation: 12,000 human athletes and 21 robot teams shared the same course.

• Technical Benchmarking: A live testbed for robot mobility, battery efficiency, and AI-driven navigation.

• Global Attention: Streamed to millions, the event highlighted China’s leadership in robotics innovation.

Meet the Robotic Contenders

1. The Sole Female Robot: Huanhuan Developed by Zhikan Shenjian Technology, Huanhuan stood out as the only female-designated robot. Competing against 21 teams, her presence symbolized inclusivity in robotics.

2. Songyan Power N2: The Confident Contender Representing Team “Whirlwind Kid,” the Songyan Power N2 robot (1.2m tall, 30kg weight) debuted with breakthroughs in dynamic balance. Key features:

   • Adaptive Gait Control: Real-time adjustments to stride frequency, length, and foot angle ensured stability at high speeds.

   • Sportswear Flair: Donning Skechers sneakers and a red “Victory” headband, it blended tech with athletic culture.

Pre-Race Preparations: A Glimpse Behind the Scenes

Days before the race, teams scrambled to fine-tune their robots:

• Last-Minute Testing: On April 17, engineers sprinted alongside robots on temporary tracks, laptops in hand, optimizing algorithms.

• Logistical Hurdles: Due to battery-related air transport restrictions, many robots traveled to Beijing via road or high-speed rail—some tucked into oversized suitcases.

• Human Endurance: Technicians, navigators, and handlers trained to run the full 21km alongside their robots, balancing code tweaks with cardio.

Racecourse Innovation: Pit Stops for Robots

Mirroring traditional marathons, the course included dedicated pit stops for robots:

• Battery Swaps: Critical for maintaining power over long distances.

• Hardware Repairs: Teams could replace components or troubleshoot issues mid-race.

• Human-Robot Handoffs: A unique rule allowed substitutions between robot and human runners at stations.

Why This Event Matters

The marathon underscored the rapid evolution of humanoid robotics, emphasizing:

• Real-World Application: Testing mobility in unpredictable, crowd-filled environments.

• Collaborative Potential: Humans and robots sharing goals and overcoming challenges together.

• Public Engagement: Inspiring interest in robotics among spectators and young engineers.

Conclusion

Beijing’s Human-Robot Half-Marathon wasn’t just a race—it was a glimpse into a future where humans and intelligent machines coexist seamlessly. As robotics technology advances, events like this will continue to push boundaries, proving that innovation thrives where technology meets human ambition.
