China's Robotera L7 Performs Sword Dance
A video of China's Robotera L7 humanoid robot performing a traditional sword dance has been showcased, demonstrating highly precise movement and balance. The performance highlights the advancing capabilities of full-sized humanoid robots in mimicking complex human actions.
- The Robotera L7 was developed by Robotera, a company spun out of China's prestigious Tsinghua University. The sword dance demonstration was staged for the 2026 Chinese New Year, with Chinese media nicknaming the robot "Linghu Chong" after a famous fictional swordsman. - The robot stands 1.71 meters tall, weighs 65 kg, and is built from lightweight materials like aerospace-grade aluminum and carbon fiber composites. Its movements are driven by a system with 55 degrees of freedom, including highly dexterous 12-DoF hands that enable fine manipulation of objects. - Its proprietary "Body and Brain" AI architecture, known as ERA-42, processes data from a 360-degree sensor suite that includes panoramic cameras and 3D LiDAR to achieve real-time environmental perception and balance. - Beyond the dance, the L7 is one of the fastest full-sized humanoid robots, capable of running at speeds up to 14.4 km/h (9 mph) and carrying a dual-arm payload of 20 kg, demonstrating its potential for logistics and industrial work. - The L7 features a modular design that allows its upper body to be used independently in industrial settings where a full bipedal form is unnecessary, such as on an assembly line. - Robotera has already seen commercial traction, reporting the delivery of over 200 units by July 2025, with customers that include nine of the world's ten largest technology companies. - The demonstration occurs within a rapidly expanding Chinese robotics sector; by 2025, the country had more than 140 domestic humanoid robot manufacturers, which dominated global market share for the year.
