Sanhua Intelligent Controls
Chinese thermal-management components maker developing electromechanical actuators for bionic robots.
- Inside Unitree Robotics, where humanoids now outsell robot dogs but nearly three-quarters go to labs and classrooms
Unitree Robotics, the Hangzhou maker of quadruped and humanoid robots that listed on Shanghai's STAR Market in August 2026, now earns more from humanoids than from robot dogs. Its filings show 73.6% of humanoid revenue in the first nine months of 2025 came from research and education buyers, the central question for a company worth about RMB61 billion at its issue price.
Mentioned - Who supplies humanoid robot joints? Japan's Harmonic Drive and Nabtesco, China's Leaderdrive and Germany's Schaeffler lead, while Tesla and Figure build their own
The joints of today's humanoid robots come from a short list of gear and actuator makers: Harmonic Drive Systems and Nabtesco in Japan, Leaderdrive, Tuopu and Sanhua in China, and Schaeffler in Germany, while Tesla, Figure and Unitree design key parts themselves. Filings show orders reaching the Japanese incumbents first, yet Tesla's stated Fremont capacity alone implies 25 million to 30 million joint actuators a year, about 22 times the 1.15 million precision reducers Nabtesco can make annually.
