Overview

Small and light enough to fall safely indoors, and it ships with Isaac Gym → MuJoCo sim2sim code and low-level torque access. It's a research kit, not a finished product. Buy direct from HighTorque's store at $5,500 rather than the ~$7.9k reseller price, but confirm stock and which compute (RK3588 vs Orin NX Pro) the $5,500 covers before ordering.

Best walking quality per dollar among small humanoids, with brushless joints at $5,500 direct.
