HONPINE has pioneered a micro harmonic drive specifically engineered for humanoid robot fingers, replacing bulky traditional ball screw designs. A single harmonic drive now powers each joint, enabling ultra-precise and agile finger movements.

Key Features of the CS Micro Harmonic Drive

• 1.2cm Breakthrough Size – Likely the world’s smallest harmonic drive, seamlessly embedded in bionic fingers.

• Independent Precision Control – Each joint operates autonomously with ≤0.1 arc-second repeatability—stable enough to grip a feather!

• 180° Ultra-Wide Motion Range – Eliminates robotic stiffness, achieving human-like fluid bending.

• Single-Joint Direct Drive – 1 harmonic drive = 1 finger joint, reducing transmission chains by 70%.

• Omnidirectional 180° Control – Full dexterity for complex tasks.

How HONPINE Achieved Millimeter-Scale Innovation

• World’s First Monolithic Harmonic Tech – Embeds drive units directly into each finger joint.

• Triple Micro-Bearing Design – Uses bevel gears to link dual-joint sections within one drive.

• Ultra-Fine ADI Material – Hollow-cast ductile iron, isothermally quenched for superior strength.

• Military-Grade Flexspline – Custom electroslag-remelted steel balances wear resistance and plasticity under high-frequency deformation.

• Triple-Stage Wave Generator – Precision-formed raceways, roller sorting, and preload assembly, validated via 3D metrology.

• CS Harmonic Drive vs. Ball Screws in Dexterous Hands

Cost-Efficiency

Despite its superior performance, the CS micro harmonic drive achieves cost parity with ball screws in mass production. Long-term, its maintenance-free design delivers higher value. HONPINE offers flexible procurement options—standalone drives or complete joint modules.
