As the first rays of dawn break over Beijing’s Yizhuang Economic Development Zone this Saturday, a historic event will unfold: the world’s first humanoid intelligent robot half-marathon. Scheduled to start at 7:30 a.m., the race will gather nearly 20 teams from across China, each fielding humanoid robots of diverse designs, sizes, and technical specifications. These mechanical contenders will tackle a 21.0975-kilometer course, a test not just of their physical capabilities but of the cutting-edge technology that powers them. For reporters on the ground, the scene promises to blend technological marvel with the thrill of competitive sport, offering a unique glimpse into the future of intelligent robotics.
A Historic Milestone in Robotics: The Race Takes Shape
The roots of this pioneering event trace back to a vision with dual purpose: to showcase the advancements in humanoid robot technology and to push its limits in real-world conditions. Since April 9, teams from cities like Beijing, Shanghai, Guangdong, and Jiangsu have been arriving in Yizhuang, unloading their robotic athletes and fine-tuning their systems. Unlike traditional robotics exhibitions confined to laboratories, this marathon thrusts intelligent robots into an environment as dynamic as a bustling city street—complete with changing weather, uneven terrain, and the presence of human runners.
“This isn’t just a race; it’s a comprehensive test of durability, reliability, and adaptability,” notes Liang Liang, Deputy Director of the Beijing Economic-Technological Development Area Development Area Administration Committee. “For too long, humanoid robots have operated in controlled environments. Here, they’ll face the unpredictable—wind, crowd noise, even signal interference. It’s a true baptism by fire for these intelligent machines.”
The Course: A Journey Through Scenery and Innovation
The half-marathon route has been meticulously designed to balance natural beauty with technological prowess. Starting at Nanhaizi Park, a sanctuary for Pere David’s deer and rare birds, the course weaves through Yizhuang’s iconic landmarks: the Paulownia Flower Avenue, a 网红打卡地 (online sensation) ablaze with purple blooms in spring, and the Wenbo Bridge, known for its architectural elegance. But the route is more than a scenic tour; it’s a testament to China’s technological rise.
En route, robots will pass by headquarters of giants like JD and BOE, Chinese companies at the forefront of e-commerce and display technology, as well as international firms like Coca-Cola. The finish line lies at the National Information Technology Application Innovation Industrial Park, a hub for breakthroughs in domestic operating systems and other core technologies. This deliberate path underscores the race’s dual identity: a celebration of both intelligent robotics and the industrial ecosystem that nurtures it.
To ensure safety and fairness, the course is divided. Human runners and intelligent robots will share the same general route but are separated by barriers, much like in a Formula 1 race where different classes of vehicles coexist yet compete independently. “The robot marathon is a team sport in every sense,” Liang explains. “Behind each robot is a crew of engineers, operators, and team leaders, all working together to optimize performance. It’s not just about the machine itself but the human intellect guiding it.”
Technical Hurdles: The Marathon as a Stress Test
For intelligent robots, a half-marathon presents unprecedented challenges—far beyond the short sprints or static displays they typically engage in. The primary concerns revolve around energy efficiency, mechanical durability, and environmental adaptability.
Battery Endurance: Perhaps the most critical factor is power. A robot running 21 kilometers must maintain a consistent pace without draining its battery prematurely. “In a lab, a robot might run for 30 minutes, but here, it needs to sustain performance for hours,” says Guo Yijie, technical lead of the “Tiangong” team. His team’s robot, the 1.8-meter-tall Tiangong Ultra, has undergone rigorous simulations to optimize energy use. “We’ve fine-tuned joint torque and rotation speed limits to find the sweet spot between speed and efficiency,” Guo notes. The robot now boasts a stable running speed of 10 km/h, with a peak of 12 km/h—speeds that demand careful battery management.
Mechanical Stamina: Long-distance running subjects robot joints to constant stress. Overheating is a major risk, so teams have integrated innovative cooling solutions. The Tiangong Ultra, for example, uses air-cooling technology in its joints to dissipate heat generated by continuous movement. Additionally, its leg design is optimized to reduce impact from high-frequency ground vibrations, enhancing stability over rough terrain. “Every joint is a potential point of failure,” Guo explains. “We’ve reinforced critical components and added sensors to monitor wear in real time.”
Environmental Adaptability: Unlike lab settings, the outdoor course introduces variables like wind, rain, and uneven surfaces. The “Whirlwind Kids” team from Songyan Dynamics, fielding the 1.2-meter-tall robot N2, has leveraged its smaller size to its advantage. “A shorter robot is less affected by crosswinds,” explains algorithm engineer Qin Bangyu. To compensate for its shorter stride, the team has optimized N2’s 步频 (stride frequency) through hardware and software adjustments, aiming for a consistent speed of at least 2 m/s. During testing, the team also addressed practical issues like foot wear and loose screws, equipping their robot with specialized shoes and planning mid-race maintenance at 补给站 (supply stations).
Star Contenders: Meet the Intelligent Robots of the Marathon
The field of intelligent robots is as diverse as the teams behind them, each showcasing unique design philosophies and technological innovations.
Tiangong Ultra: The Giant Strider
Standing at 1.8 meters, the Tiangong Ultra is one of the tallest competitors. Its designers at Beijing-based research teams focused on balancing speed and stability. “We incorporated human movement data into our training algorithms,” Guo says, “so Tiangong’s running posture is as natural as a human’s.” The robot’s lightweight frame, achieved by omitting non-essential components like dexterous hands, allows it to move more efficiently. During tests, it navigated turns and slopes with remarkable agility, a testament to its advanced environmental perception systems.
N2: The Compact Dynamo
In stark contrast, the 1.2-meter N2, nicknamed “the Little One,” proves that size isn’t everything. Songyan Dynamics’ team, composed largely of post-1995 and post-2000 engineers, emphasizes adaptability. “Our strategy is to use agility to overcome physical limitations,” Qin explains. N2’s smaller stature makes it more resistant to wind, and its optimized algorithms enable quick adjustments to terrain changes. The team’s innovative solution to foot wear—attaching specialized shoes—highlights the practical engineering needed for real-world robotics.
Race Logistics: How an Intelligent Robot Marathon Works
Organizing a race for intelligent robots comes with unique challenges, from technical support to rule-setting.
Supply Stations: Pit Stops for Robots
Just as human runners need water and nutrition, intelligent robots have their own supply needs. The race features designated supply stations stocked with spare batteries, tools, and replacement parts. “Think of battery changes like tire changes in Formula 1,” Liang says. While teams are encouraged to complete the race with a single robot and no battery swaps, practicality allows for adjustments. “If a robot encounters unexpected power drain, it can stop for a battery change. The key is to balance speed with reliability.”
Backup Robots: Plan B for Technical Glitches
Despite rigorous testing, technical issues can arise. Teams are permitted to switch to a backup robot if faced with severe malfunctions, such as the impact of strong winds or unforeseen signal interference. “This isn’t a flaw but a reality of pushing technology to its limits,” Liang notes. “The goal is to see how far robots can go, not to penalize teams for unforeseen challenges.”
Control Modes: Autonomy vs. Remote Operation
The race allows multiple control methods. Some robots will rely on autonomous navigation, using cameras and sensors to map their path. Others will be followed by human operators, while a few may even be remotely controlled. “This diversity showcases the different paths in intelligent robot development,” Liang says. “Some teams prioritize full autonomy, while others see human-robot collaboration as the way forward.”
Awards: Celebrating Innovation Beyond Speed
The marathon’s award structure reflects its mission to promote technological diversity, not just raw performance. In addition to traditional first, second, and third places based on finish time, the race will honor:
- The Best Endurance Award: Recognizing robots that demonstrate exceptional energy efficiency and reliability.
- The Popularity Award: Voted on by the public, celebrating robots that captivate audiences with their design or functionality.
- The Most Elegant Gait Award: A nod to robots that achieve natural, human-like movement.
“Performance is important, but we don’t want to limit the definition of ‘success’,” Liang explains. “An intelligent robot that interacts smoothly with humans or adapts brilliantly to obstacles is just as valuable as one that runs the fastest. This race is about showcasing the full spectrum of robotic innovation.”
Public Engagement: Bringing the Race to the World
While the course will host both human and robotic runners, organizers encourage the public to watch online. The event will be livestreamed across multiple media platforms, allowing viewers to follow the action in real time. “The combination of human athletes and intelligent robots on the same route is a visual spectacle,” says a race spokesperson. “Through live broadcasts, we hope to share this historic moment with as many people as possible.”
Viewers will also have the chance to engage through interactive polls, voting for their favorite robots in categories like “Most Aesthetic Design” or “Most Innovative Technology.” This public participation aims to bridge the gap between cutting-edge robotics and the general public, fostering understanding and excitement about intelligent robot advancements.
