Registry and build pipeline · sheet 01

From “I want this robot” to a robot standing on your desk.

Every open robot compiled into one build package: a parts cart for your region, a print plan for your bed, an assembly graph with a check at every step, and bring-up to a first policy. Each package carries a level. Levels are earned by evidence, never by an agent’s confidence.

How a build runs

6 stations · same order on every robot page

01Configure
Region, printer bed, budget, print or order the printed parts.
02Source
One cart across suppliers. Maker's own kit first. Unpriced lines flagged.
03Fabricate
Printed parts, material, grams, hours, plates for your bed.
04Assemble
A step graph with parts in, tools, torque and a check at every step.
05Bring-up
Flash firmware, calibrate, run a first policy from .training.
06Report
Photos and a bring-up log. Reports are what raise a robot's level.

Verification ladder

A wrong torque value strips a gear; a wrong battery step starts a fire. So the registry is grouped by what has been proven, not by popularity. Counts below are live from the registry.

L130
Compiled
Package validates against the spec; every fact has a source.
L222
Sim-verified
Loads in browser and GPU sim, mass within tolerance of the BOM, holds a stand. Unlocks .training.

Sourced
Every BOM line resolves to a live offer in at least two regions. Unlocks the one-click cart.

Built
At least one community build report with photos and bring-up logs. Unlocks Build it as the main action.
L50
Certified
The robot's maintainer signs the package. Unlocks certified teams and kit sales.

Your robot is not here?

Packages are drafted from public repos and published through the Open Robot Package spec. A maintainer can publish one with npx orp init and it appears here, on .training and on .systems.
