Documentation
Start with the Quickstart: from a robot file to a policy running on a robot, in the browser. Each page says what runs where, and what costs money, as plainly as what it does; the paid backends — cloud GPUs and the Coach’s model — run only where this deployment has them, and say so when it does not.
Guides
In the order a stranger walks them: the path first, then why it is safe, then each surface.
- QuickstartIn the browser: add your robot from a zip, train its first policy, gate it in sim, connect a robot with a code, deploy and stop it — and the one terminal step, for jobs on your own machine.
- How it worksThe three claims the hub rests on, what a person approves before a policy reaches a robot, what an agent's key can do, the Coach, and Laika.
- Add your robotFrom an MJCF or a URDF to a validated robot page — a zip dropped in the browser, or three commands: what is derived, what you must declare, and what gets refused.
- Connect your robotPair a robot from its page with a code, and write a lucen-device adapter for your own robot: the plugin entry point, the protocols, and the fail-safe the driver insists on.
- From a terminalThe CLI path: install lucen, sign in with a key, pull and push a dataset, import a run, train on a runner you start and gate it in sim — every command run verbatim.
- From Pythonfrom lucen import Hub — the CLI's own push, pull, train, follow and sim-gate engine as a small typed Python API for scripts and notebooks; every example on the page is run against a hub by a test.
- MCP setupInstall and configure the lucen-mcp server, every tool it exposes with the scope it needs, and which of them wait on a worker you start.
- Dataset formatThe LeRobotDataset layout the hub reads, which versions the episode viewer supports, and what it does with the rest.
- Self-hostBoot the whole hub on one machine from a checkout — Postgres, S3, API and web — and what a local stack does not have.
- GlossaryEvery hub word the pages explain on hover — policy, reflex, sim gate, fingerprint, endpoint, scope — in one sentence each, with the page where you first meet it.
