Reducers & Harmonic Drives Suppliers for Humanoid Robots
About This Category
Gear reduction units that lower motor speed while multiplying torque for joint actuation. Harmonic (strain-wave) reducers are the dominant type in humanoid robots due to zero backlash, high reduction ratios, and compact form factor.
Every humanoid joint typically requires 6–20 reducers. Zero-backlash precision is non-negotiable for dexterous motion. No joint movement is possible without them.
