Robot arms & LeRobot

This is the first category we opened, not the only one, and the SO-101 vs SO-100 pair is not the only arm we'll cover. We're collecting what's public about low-cost arms and kits that run LeRobot, and writing it up with sources and dates.

More arms and kits will be added over time, once we've read the sources. There is no fixed list yet, and nothing below is written.

Follow-ups to the SO-101 guide, if we build one and can say what we did.
