Robot Actuators & Joint Modules from China

Integrated joint modules — motor, gearbox, encoder and driver in one package — are the part of the humanoid supply chain where Chinese pricing is most aggressive: QDD modules start near $180 where Western equivalents run 5–10×. Below is every actuator line we track, with rated torque, gear type and encoder configuration compared in one table. Figures marked † are manufacturer-reported; we re-check quarterly.
