Video: China's humanoid robot Robotera L7 performs stunning sword dance

China’s Robotera has released a video featuring its humanoid robot, the L7, performing a traditional Chinese sword dance to celebrate the Chinese New Year of the Fire Horse. Developed with Tsinghua University, the L7 stands 5.6 feet tall, weighs about 143 pounds, and is constructed from titanium and carbon fiber for strength and lightness. It boasts 55 independently moving joints, including 7 per arm and 12 in the hands, enabling complex motions such as arm rotation, wrist flipping, and grip adjustments. The sword dance demonstration highlights the robot’s advanced full-body control, precise timing, and high-speed directional changes, requiring stable landings and careful coordination to avoid self-injury with the blade. The L7’s performance is powered by an embedded AI control system that manages whole-body dynamic coordination, real-time motion planning, torque control, and multi-axis balance during rapid movements. This sophisticated control allows the robot to maintain stability and fluidity even during jumps and spins,
