The best-documented humanoid maker — find independent technicians who know Unitree hardware.
Unitree Robotics of Hangzhou built its name on quadrupeds — the Go1, Go2, and industrial B2 — before launching the full-size H1 humanoid in 2023 and the compact G1 after it. That lineage matters for service: years of shipping legged robots produced a mature actuator supply chain and, unusually for the industry, a genuine public documentation culture at support.unitree.com.
Technicians experienced with Unitree hardware know the G1 (1.27 m, ~35 kg, 23 degrees of freedom), the H1 (1.80 m), and the Go2 quadruped. Common service work includes actuator replacement, battery swaps, and SDK/firmware updates — all well covered by official docs, which makes Unitree the friendliest brand in the industry to service.
