Products
Both ship assembled and tested — motor, reducer and output bearing in one housing, without a driver board.

P5 · Compact
20:1 single-stage reduction at 220 rpm, 220 g. For grippers, wrists and pan-tilt heads.
P10 photo · images/p10.jpg
P10 · Fast
20:1 single-stage reduction, 700 g. For arm joints, legs and mobile bases.
Inside
Motor, reducer and output bearing share one housing. High ratio from a handful of parts, shock-tolerant, low backlash — and nothing in the bill of materials you can't source.
Specifications
Measured on final-design units. Anything still in final validation is marked, not guessed.

Disclaimer. Final testing is still in progress, so these are not the final parameters — they come from our latest test runs and may change before the first batch ships. Datasheet and CAD published before shipping. Prices exclude shipping and taxes.
Driver
P5 and P10 ship with zero electronics: motor, reducer, bearing. Pair them with the FOC board and encoder you already use.
Roadmap
Small team, built in batches. Pre-booking tells us how many to build.
Design complete. Torque, thermal and endurance runs on final-design units; the datasheet locks before shipping.
A limited number of samples go to early users first, then the batch ships in sign-up order. Pay only when your unit is ready.
Bolt-on FOC board with encoder first; more actuator families and robotics components after.
Why $60
Imported joints in this class cost several times more. We took the price out of the design, not the build.
High ratio from a handful of parts, no exotic components, tolerances where they matter.
Engineered and machined by us, close to where you are. No import margin, no distributor stack.
We build to pre-book demand and bench-test every unit. Small batches keep the price where it is.
FAQ
No. It's a free reservation. When your unit is ready we email final specs and shipping cost; you decide then.
An assembled, bench-tested actuator: BLDC motor, reducer, output bearing. No driver board, no encoder — add your own, or wait for our integrated driver.
Any 3-phase FOC board rated for 12–24 V — SimpleFOC, ODrive, Moteus class. Motor constants are published before shipping. Add the custom mount ($30) to bolt your board on.
Nearly. The design is complete; torque, speed, size and mass are measured on final-design units. Peak torque and backlash are in final validation, and the datasheet locks before shipping.
Yes, for a limited number of users. Tick the sample box in the pre-book form and we’ll try to get a unit to you before shipping starts, subject to availability.
First batch Q4 2026, in sign-up order. Worldwide; shipping cost confirmed before any payment.
Possibly. Describe it in the pre-book form and we'll say what's realistic.
