Overview

Best ready-made pick around $6k, with an open SDK and open RL pipeline on every tier.

The best small ready-made humanoid for simulation-focused developers. It is kid-sized and light enough to catch, and Booster publishes the whole train → sim2sim → deploy stack, with the SDK open even on the cheapest tier. Get the 5 Ah battery (the Geek's 2 Ah pack lasts ~30 min). It's slow and the arms are mostly for show, but for locomotion experiments it's the one to beat. Faraday Future's $9,990 Master Mini (September 2026) lists Booster SDKs and a K1-matching size and 22 DOF, so it appears to be a rebadged K1 (unconfirmed).
