From zero to a robot that learns

The complete path into robotics on a hobby budget: pick a cheap arm, drive it, record data, train it, and understand the space you just joined. Written in plain English, in order. No PhD, no lab.

1 · Get a robot

How to choose your first robot armThe honest buying guide: SO-101 vs the alternatives, real price bands, and what you actually need to start.
The SO-101 setup checklist: from box to moving armAssembly resources, the exact install commands, motor setup, and calibration, in order, from the current official docs.
Your first teleoperation sessionThe command that makes the follower copy your hand, what to expect in the first hour, and the failures everyone hits.

2 · Make data

How to record your first robot datasetThe exact record command, the settings that matter, and the data-collection habits that make your episodes worth training on.
How to share a robot dataset people can actually useLint it, license it, push it, and watch it show up with its own public scorecard.

3 · Train a brain

How to train your first robot policyFine-tune ACT or SmolVLA on your own episodes, on your GPU, a rented one, or a notebook, with the honest time expectations.
Why your policy fails, and what to record nextThe iterate loop: read the failures, record targeted episodes, retrain. This loop is the actual job.

4 · Understand the space
