Ways in / 01Makers, students, labs

Robot parts that arrive finished.

Motor nodes with the driver, encoder, controller and gearbox built in. Plug in a USB-C charger, open the app in a browser, move. They’re the units our commercial leader arm is built from.

01Why nodes

It’s found, named and ready when you plug it in.

No wiring puzzle

No driver, encoder, microcontroller and supply to match up. One calibrated unit.

One app

Calibration, limits, jogging and live plots in the browser. The same app runs one node or a full station.

Python when ready

Script one node or a dozen over CAN, from Python, ROS 2 or LeRobot.

Test card in the box

Each unit’s measured numbers, printed and stored on the node.

02Planned prices

Every node, in one list.

Planned list prices. Nothing is on sale yet; registered interest sets the order of the first batch.

03Upgrade path

Board, then node, then geared node.

Start with a board on your own motor, add our motor and housing later, then a reducer. The node keeps its identity and calibration history as it grows.

04Who it’s for

For people who build.

Printer and CNC upgraders

Closed-loop axes that report a stall instead of shifting a layer, on STEP/DIR from Klipper, Marlin or GRBL.

Robot-arm builders

Joints that know their position, on one cable, without a pile of separate electronics.

LeRobot and SO-101

Quiet, backdrivable joints with calibration that lives on the node, for leaders, wrists and grippers.

FOC tinkerers

Field-oriented control on gimbal motors without assembling a driver, encoder, MCU and supply.

Camera and astro rigs

Silent, repeatable moves for sliders, pan heads and turntables.

University labs

Documented parts for courses and research rigs.
