In a historic first, humanoid robots exchanged rapid punches and kicks during a live combat sports event in Hangzhou, eastern China, on Sunday, marking a groundbreaking moment for both robotics and competitive athletics.
This unique event was part of the China Media Group’s (CMG) World Robot Contest and was held at the Olympic Sports Center. It featured humanoid robots engineered by Unitree Robotics, a tech company based in Hangzhou.

Titled the “Mech Combat Arena Competition,” the event was broadcast internationally and included both demonstration bouts and competitive matches between cutting-edge robotic fighters.
Organizers explained that the robots were outfitted with highly advanced motion control systems, enabling them to perform intricate martial arts maneuvers — from jabs and hooks to powerful sidekicks. The robots also demonstrated the ability to quickly recover after falls, highlighting significant progress in balance and reflexive movement for humanoid machines.
Unitree Robotics’ marketing manager, Sun Baoyan, noted that delivering high-speed leg movements demanded extremely fast sensory feedback and motor coordination. “The control system must interpret data from internal sensors in real-time and synchronize joint movements within milliseconds, which is a serious challenge in terms of durability and precision,” she said.
Developers acknowledged that preparing these robots for physical confrontation required solving several engineering hurdles — including maintaining stability, preventing overheating, and extending battery performance during intense activity.
Wang Qixin, a board member at Unitree Robotics, added that a significant amount of development went into optimizing motion algorithms for combat efficiency. “Designing anti-fall systems alone demanded a great deal of effort to ensure the robots could remain competitive in the arena,” he explained.
All components — both hardware and software — were produced domestically, showcasing China’s rapid progress in artificial intelligence and robotics development.
To enhance the viewer experience, CMG deployed cutting-edge broadcast innovations, including augmented reality (AR), virtual reality (VR), and dynamic 360-degree camera systems. Jiang Hua, the chief technical director of the event, shared that these tools were designed to make the robots appear more lifelike and captivating to online audiences. “This isn’t just a competition — it’s a showcase of visual and technological excellence,” he said.
The event also featured expert commentary that analyzed the robots’ techniques and functions in real-time, making the experience both educational and entertaining for viewers.
