In a world-first, humanoid robots traded swift punches and kicks in a live combat sporting event held in Hangzhou, eastern China, on Sunday marking a significant milestone in robotics and competitive sports, Samaa TV reported.
The event, part of the China Media Group (CMG) World Robot Contest, took place at the Olympic Sports Center and featured machines developed by Unitree Robotics, a Hangzhou-based technology firm.
The contest, dubbed the "Mech Combat Arena Competition," was streamed globally and showcased exhibition and competitive matches between the advanced humanoid fighters.
According to organisers, the participating robots were equipped with state-of-the-art motion control systems that enabled them to execute complex martial arts techniques, including straight punches, hooks, and sidekicks. The machines were also capable of swiftly regaining posture after falling -- a task that continues to test the limits of robotic balance and reaction time.
Sun Baoyan, marketing manager at Unitree Robotics, said executing a high-speed leg swing required instantaneous sensory processing and motor control.
“The motion control programme must process data from internal sensors in real-time and coordinate the joints in milliseconds. This is extremely demanding in terms of stability and endurance,” she said.
Developers noted that preparing humanoid robots for high-impact confrontations also poses significant engineering challenges, particularly in ensuring stability, managing heat dissipation, and prolonging battery life.
“We’ve had to optimise a large set of motion control algorithms specifically for fighting moves,” said Wang Qixin, a member of Unitree Robotics’ board.
“Anti-fall capability, for instance, required intensive development to ensure the robot could perform effectively under competitive conditions.”
All technologies used in the robots — including hardware components and software systems — were domestically developed, underscoring China’s rapid advancements in AI and robotics.
To complement the live competition, CMG introduced innovative broadcasting techniques, including AR, VR, and free-view camera systems. Jiang Hua, the event’s chief technical director, said the goal was to make each robot appear lifelike and engaging in livestreams.
The event also featured expert commentators and analysts, providing live breakdowns of the robots’ mechanics and strategy making it as much an educational experience as a spectacle of futuristic sport.
