The event is part of a series of robot challenges co-hosted by China Media Group and other institutions.
In one recent session, two robots built by Hangzhou startup Unitree Robotics sparred in the ring, showing off moves like aerial spin kicks and quick recoveries after falls.
Engineers say the robots have been systematically upgraded, with improved algorithms and resilience to withstand heavy blows.
The boxing bots have been trained using a vast database of combat movements, refined frame by frame.
