Dexterous hands and micro drives
A dexterous hand packs reducers, micro motors, transmissions and sensing into a palm, with degrees of freedom from six to more than twenty.
The difficulty is the triangle of volume, weight and cost: at the same degree of freedom, weight can differ by a factor of two and price by several times.
Delivery is mostly low volume today, with consistency resting on manual assembly and per-unit calibration.
Basis: Industry-structure assessment (Tier C, our own judgement); contains no hard numbers.
Where the barrier sits
- Micro-drive efficiency and backlash across the three routes: screw, tendon, linkage
- Fingertip force control and tactile feedback
- Whole-hand weight to degrees-of-freedom ratio
- Per-unit calibration and consistency
Price and lead time
Price band pending. Must state: number of active degrees of freedom, whole-hand weight, whether tactile sensing and controller are included, and order quantity band.
| Data sheet | Status | What the basis must cover |
|---|---|---|
| DOF and weight comparison | Pending | Active DOF / whole-hand weight / fingertip force |
| Cost breakdown | Pending | Micro motor / reducer / transmission / sensing / assembly |
| Lead-time distribution | Pending | Prototype and batch reported separately |
