China hosts the first mechanical mixed martial arts tournament

The world's first robot MMA event amazed audiences with AI-trained bots showcasing martial arts skills in China.

: The world's inaugural humanoid robot kickboxing contest was held in Hangzhou, China, on May 25, 2025, featuring Unitree Robotics' bots. Resembling old Robot Wars shows, four G1 robots engaged in combat, each weighing 35 kilograms and standing 132 centimeters tall. These matches, aired on Chinese Central Television, demonstrated the combination of silicon and sinew, as the AI-trained robots performed skill showcases and three combat rounds. This tournament is seen as a leap in humanoid robotics, surpassing even Boston Dynamics' accomplishments, though concerns over robot safety persist.

On May 25, 2025, the history of martial arts and robotics converged in an extraordinary event in Hangzhou, Zhejiang province - the world’s first mechanical mixed martial arts tournament. The China Media Group World Robot Competition – Mecha Fighting Series, inaugurating this novel spectacle, showcased humanoid robots battling in a controlled environment reminiscent of entertainment from decades past like Robot Wars. However, unlike its predecessor, this event featured less violence and was broadcasted on the state-run Chinese Central Television, reaching a wide audience that marveled at human ingenuity and technological prowess.

Designed by Unitree Robotics, the star robots of the event were the G1 series, each approximately the size and weight of a petite adult human, measuring 132 centimeters tall and weighing 35 kilograms. These robots took part in a series of matches designed to test their capabilities in humanoid combat. Each bout was divided into two sections: an initial skill demonstration, showcasing their balance and coordination, followed by three rounds of actual combative interactions lasting two minutes each. In each fight, robots earned points for executing punches and kicks effectively, with higher points awarded for kicks.

Though the matches were conducted under the watchful eyes of human operators and referees, the true innovation lay behind the scenes, as articulated by Wang Qixin, the Director from Unitree. These robots were trained using Artificial Intelligence (AI) techniques. Initially, the movements of professional kickboxing athletes were captured and analyzed. Subsequently, these movements were introduced into a virtual training environment where robots learned and honed their martial arts skills.

This captivating event was not merely for entertainment; it represented a substantial advance in the field of humanoid robotics. Experts from Zhejiang University, such as Li Gaofeng, celebrated the technical achievement, noting the sophistication in full-body coordination required. Such developments have established Unitree Robotics as a leading competitor in the realm of robotic engineering, drawing comparisons with Boston Dynamics, known for its Atlas robots. While some contest Unitree's effectiveness over Boston Dynamics' precision, the growing competitive spirit between these companies promises further technological progress.

The tournament also served as a reminder of ongoing safety challenges with humanoid machines. Notably, a recent incident involving a Unitree H1 robot exhibited erratic behavior during a factory test, which heightened safety concerns. Offering a glimpse towards future ambitions, Shenzhen-based EngineAI announced plans for larger-scale robot combat events designed to escalate both AI and engineering innovation. Meanwhile, Unitree is intent on bringing kickboxing robots into consumer markets, advancing both the technology and the exciting prospect of personal robot trainers in the coming years.
