Humanoid Robot Supply Chain
Component makers, precision manufacturers, and technology firms whose parts go into every joint, sensor array, and computing module.
137 suppliers · 15 component categories · 4 OEM networks documented · 7 countries of origin
The humanoid robot hardware ecosystem is concentrated in China, with documented suppliers headquartered across Ningbo, Shenzhen, Suzhou, Shanghai, Beijing, Changzhou, and Hangzhou. Key component categories include harmonic and planetary reducers (20 suppliers), sensors covering 6D force-torque, IMU, tactile, vision, and LiDAR systems (19 suppliers), precision screws and ball screws (15 suppliers), and coreless and servo motors (10 suppliers). Dexterous hand units and tactile sensor assemblies represent the least mature supply segment, with several key providers operating as private companies. The four documented OEM customer networks are Tesla Optimus (46 supplier relationships), AgiBot A2 and X1 (32 supplier relationships), Unitree G1 and H1 (22 supplier relationships), and Figure AI (9 supplier relationships).
