China's L7 humanoid hits 9 mph to become 'fastest bipedal robot'

China’s L7 humanoid robot has set a new benchmark as the fastest bipedal robot, capable of sprinting at speeds up to 14.4 km/h (9 mph). Standing 5.7 feet tall, the L7 combines impressive mobility with advanced dexterity, featuring 55 degrees of freedom and delivering up to 400 Nm of torque. This enables it to perform a wide range of tasks, from industrial operations like sorting, scanning, and using power tools, to athletic feats such as 360-degree spins and breakdancing. It can lift loads up to 44 pounds with both arms and demonstrates sophisticated visual recognition and manipulation skills, highlighting its potential for real-world applications in manufacturing, logistics, and service environments. The L7 represents a significant engineering advancement by integrating a unified “body plus brain” architecture that addresses the complexity challenges associated with scaling humanoid robots. This design allows it to execute both large-scale movements and fine motor tasks with remarkable coordination and control. A demonstration
