How China Made Humanoid Robots So Cheap

A humanoid robot got 72% cheaper in two years — Unitree's average price fell from about $85,000 to $25,000 — while the maker's gross margin went UP, from ~44% to ~60%. Falling prices are supposed to crush margins. This one expanded them. The answer is in the title: the cheap part isn't the robot — it's the country it's built in. A humanoid is a bag of expensive joints wrapped in cheap plastic, and Unitree makes those joints itself, riding the same motor-battery-sensor supply chain China mastered building electric cars. McKinsey estimates rebuilding Tesla's Optimus without Chinese suppliers would roughly triple the parts bill — from about $46,000 to $131,000. The body is Chinese. But we build it through the hard question: do these cheap robots actually do any work? Mostly — not yet. About three-quarters of its sales go to research labs and schools ("dancing, not working"), and even Elon Musk admits Optimus is "still in the R&D phase… not in usage in our factories in a material way." A lot of what looks autonomous is a human in another room with a controller. So which is it — a breakthrough, or an expensive parlor trick? Both. China built the cheapest body in the world; the brain — the AI — isn't ready. Unitree's Wang Xingxing and Figure's Brett Adcock reconcile it, and we close on three dated predictions. Not investment advice — one read of the public record, as of June 2026.
