Humanoid Robot Kuafu Advances China's 15th National Games Torch Relay

China's 15th National Games featured a historic torch relay with a humanoid robot named Kuafu (also referred to as Kuavo) as a special torchbearer, marking a significant advancement in robotics and AI technology. Developed by Leju Robotics and supported by institutions like China Mobile and the Harbin Institute of Technology, Kuafu carried a 1.6-kilogram torch over about 100 meters with lifelike running motions, showcasing dynamic motion control, load-bearing stability, and 5G-Advanced connectivity. This robot is recognized as the world's first 5G-A humanoid torchbearer, capable of autonomous and precise execution without human assistance, symbolizing technological ambition and endurance. The relay event, held simultaneously across multiple Chinese regions, highlighted a fusion of sport and high technology, and Kuafu's role was a key highlight distinct from previous robotics displays at international games, which lacked Kuafu's autonomy and stability. While Kuafu did not light the main cauldron, its participation underscored China's leadership in embodied intelligence and smart technology integration in public events. The torch relay also featured a unique source flame ignited by combustible ice from the South China Sea, adding to the symbolic significance of the event.
