Humanoid robots are usually discussed as a demand story about a future market. The companies that will supply them are already listed, already reporting, and already being valued on today’s numbers, which makes the control layer one of the more useful places to look at what the industry actually earns.
Where the value sits
The upstream layer supplies control chips, compute boards, servo drives, encoders, inertial and force and vision sensors, alongside software including real-time operating systems, motion control libraries, gait and balance algorithms and embodied models. This is where sensing, compute and low-level actuation live.
The midstream holds control system vendors and body manufacturers, integrating the cognitive and motor layers, closing the perception to decision to motion loop and adapting the whole stack to a specific machine. The downstream is deployment in industrial, commercial service, home care and hazardous work.
The technical barriers remain in high-end chips, high-precision sensing and core control algorithms, and domestic suppliers are substituting across hardware and software together. What the financials show is that substitution is not evenly profitable.

Reading the table
Three things fall out. First, the component franchise is the best business in the stack. Sanrui’s 44 per cent return on equity at a 60 per cent gross margin is not a humanoid story at all, it is a precision actuator story that happens to have a humanoid customer base, and it will survive a humanoid slowdown.
Second, the cognitive layer is being paid like systems integration. The company ranked first as a brain supplier ran a 1.3 per cent revenue compound growth rate and a 20 per cent gross margin. Ranking first here is a statement about relative durability, not about pricing power. Whoever assembles the compute and software for a customer’s brain is doing integration work, and integration work compresses.
Third, cash flow quality varies more than profit does. Estun’s operating cash flow grew nearly eightfold against revenue growth of 22 per cent, which is the signature of a working capital release rather than a demand surge. Veichi and Xinje both converted decent gross margins into negative cash flow growth. Gross margin is a claim about pricing. Cash flow is what happened.
The screen is a static, historical exercise and says nothing about the next twelve months. But it does establish a baseline that the humanoid narrative tends to skip: in the quarter when shipments began to scale, the suppliers with the strongest economics were selling joints, not judgement.
