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.
