When this is the right choice
- Passive joints are the feature. Ten of the twenty joints conform mechanically, so a grasp wraps an irregular object instead of fighting it.
- 800 g and 80 N. More grip than the O6 at twice the mass, with far better object conformance.
- Cheapest route to a 20-joint hand. The value model in the high-DOF half of the range.
- Same SDK as every other Linker hand — a lab can start here and move up without retraining.
When it is the wrong choice
- Precise in-hand manipulation. The ten passive joints are compliant, not controllable.
- Fast cycles. 1.2 s full close is the slowest in the range; a pick cell needs L6 or O20.
- Datasets that must distinguish every joint — a passive joint cannot report its own state.
Alternatives at a similar level
- Linker Hand L20 — 16+5 DOF, 100 N grip, 1.2 kg — full articulation
- Linker Hand O6 — 6+5 DOF, 360 g, 50 kg grip, the cheap work hand
- Linker Hand L6 — 6+5 DOF, 607 g, 201°/s, built for cycle life
- Linker Hand O30 — 20 direct-drive joints with tactile options

Linker Hand L20 Lite FAQ
What do the 10 passive joints actually do?
They let each finger conform to the object: when it closes on an irregular part, the passive joints follow it instead of stopping at a programmed shape. That is why a 10-active hand can out-grasp a 16-active one on awkward objects.
Can I record the passive joints for a dataset?
They are not actuated or sensed as independent DOF in the control model, so the dataset sees the commanded joints. If per-joint ground truth matters, that is L20.
Is it good enough for a teaching lab?
That is what it is designed for: 20 joints, 800 g, SDK with ROS and URDF, at a price point that lets a lab buy two hands instead of one.
How long does it take to ship?
Confirmed per order at quotation.
