About the Inspire LAF10 Linear Servo Actuator
The Inspire LAF10 linear servo actuator is a micro force-controlled actuator with a 10 mm stroke — a coreless motor, precision planetary reducer, lead screw and closed-loop controller integrated in a 29 g body, with a built-in force sensor that reads push and pull force in real time. This listing is the LAF10-024D, the 70 N variant that drives the fingers of Inspire's dexterous hands.
Buyers come to the Inspire LAF10 linear servo actuator for two reasons: as a replacement finger actuator for an Inspire dexterous hand — including the hands fitted on Unitree humanoids — or as an off-the-shelf force-controlled linear drive for their own gripper or precision automation build. The sections below cover both.
What the F Adds: a Force Sensor in the Loop
The Inspire LAF10 linear servo actuator builds a high-precision force sensor into the push rod path, reading push and pull force across a −100 N to +100 N range at 1 N resolution — so a controller can close the loop on force, not just position. A gripper can press until it feels a set force and hold it there, instead of driving to a position and hoping.
Position is handled by a built-in absolute encoder: the actuator knows where the rod is at power-on, with no homing move and no position loss after a power cut. Motor, planetary reducer, lead screw, sensors and controller all ship inside one 77 mm-class body — there is no external driver to wire.
- Built-in force sensor — real-time push/pull force detection and closed-loop force control
- Absolute position encoder — no homing, no position loss on power-off
- Fully integrated: motor, reducer, screw, sensors and controller in one body
LA, LAF or LASF? Picking from the Same Family
Inspire's 10 mm-stroke micro actuators come in three flavors of the same family. The LA10 is the base position-controlled actuator. The LAF10 — this page — adds the built-in force sensor for push-pull force closed-loop control. The LASF10 is the higher-force sibling of the same idea, built for jobs like driving the thumb of a dexterous hand.
If your mechanism needs to feel how hard it is pushing — gripping, pressing, compliant motion — you want the Inspire LAF10 linear servo actuator, not the LA10. If you need clearly more force than the LAF10 offers, look at the LASF10 instead.
Where the LAF10-024D Sits: Speed Level 02 vs 07
The Inspire LAF10 linear servo actuator family comes in speed levels built from the same body, sensor package and 10 mm stroke — what changes is the gearing. This listing is the LAF10-024D, the level-02 variant that trades speed for force; level 07 does the opposite.
| Speed 02 — LAF10-024D (this listing) | Speed 07 | |
|---|---|---|
| Max force | 70 N | 42 N |
| Locked-rotor force | 100 N | 60 N |
| Max self-locking force | 100 N | 50 N |
| No-load speed | 18 mm/s | 50 mm/s |
| Full-load speed | 8 mm/s | 21 mm/s |
| No-load current | 0.23 A | 0.53 A |
| Typical use | Dexterous-hand fingers, high-force pressing | Faster motion at lighter loads |
The Finger Actuator of Inspire's Dexterous Hands
Every Inspire RH56-series dexterous hand is driven by six micro linear servo actuators: the four fingers each run an Inspire LAF10 linear servo actuator — the 70 N LAF10-024D sold here — while the thumb's two drives use the higher-force LASF10-024D. A hand that has lost a finger usually needs exactly one of these, sold per unit.
Those hands are the dexterous-hand option on Unitree humanoids — the RH56DFQ on the G1 EDU higher tiers and H2-D, the tactile RH56DFTP on the G1 EDU Ultimate, H1 and H2 — so the LAF10-024D is also the finger-level spare for the Inspire hands on those robots.
