About PlanetaryDriver

The drive behind every joint.

PlanetaryDriver exists to make building quasi-direct-drive (QDD) and pancake robot actuators dramatically less painful. If you've tried to source a matched motor, FOC driver, encoder and the right magnet for an ODrive, SimpleFOC or moteus build, you know the parts are scattered across a dozen shops, specs are inconsistent, and half of what you buy doesn't actually play nicely together.

What we do

We curate a focused catalog of actuator parts — motors, FOC drivers, encoders, gearboxes, magnets, power and connectors — plus pre-matched, compatibility-checked kits so you can buy a whole actuator that's known to work, not a bag of maybes. Every product page lists the specs and compatibility notes that actually matter.

How orders work

We're honest about fulfillment: most items ship from our vetted supplier network, so typical delivery is around 2–3 weeks — see Shipping for details. Every order gets tracking, free US shipping, and is backed by our 30-day guarantee. If something arrives dead or wrong, we make it right.

More than a store

PlanetaryDriver is also a community for open-source robotics builders — share your builds, read and post guides, swap 3D-printable parts, and get help in the forum.
