- 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.
