I believe this conclusion is flawed. The author argues:
1) Unitree robots are largely made by hand.
2) Labor is approximately 8% of cost of manufacturing these robots. Because these costs are not prohibitive, there is little incentive to automate.
3) Labor costs are higher in America.
4) Therefore, American companies have higher incentive to automate.
5) Therefore, the West will capture most of the robotics opportunity.
Arguments 1-4 are reasonable, but 5 is a non-sequitur. Higher incentive to automate does not imply a better ability to automate & scale manufacturing.
I believe Unitree is currently assembling robots by hand for practical reasons:
1) Labor is still relatively cheap.
2) Humanoids and robots are evolving rapidly, changing every few months.
3) Custom assembly lines are expensive, and become obsolete when the product changes. It's difficult to maintain an assembly line when the product is rapidly evolving.
4) Tooling is inadequate. Some robotic parts are delicate, complicated, and difficult to automate manufacturing of. American companies have hit the exact same problem: Tesla is assembling the hand/forearm of Optimus by hand because it hasn't figured out how to automate manufacturing them. https://www.theverge.com/tech/1016492/tesla-optimus-robots-p... . Apparently, Tesla has hundreds of handless Optimus robots just standing around, waiting for hand manufacturing to catch up.
5) Demand is still relatively niche, these are not mass market products. Unitree only sold 5,500 robots last year. There is not enough demand to justify massive automated lines.
The author also ignores the biggest counterpoint: the Chinese have already demonstrated mastery in automated manufacturing, and have proven they can run dark factories (factories without humans) at a better scale than the west.
When humanoid robots become a mass market product (they are not ready today because the software side is majorly lacking), Chinese manufacturers are in an excellent position to rapidly automate.

Yes, the article doesn't really tell us much.
Motor winding is an amusing problem. Everybody making motors has a powered winder. It's handling the wire ends that can be either manual or automatic. If you look at videos of winders, automating the wire end handling is most of the machinery.
Here's an overview of winding automation:
Full auto, robotic transfer.[1]
Full auto, manual transfer [2].
Semi auto. [3].
Manual, powered. [4]
Manual, unpowered motor overhaul.[5] (Country girl in China who fixes motors and engines.)
Those winding machines are all from the same company, NIDE. You can buy as much automation as you want, depending on your labor costs. Option [4] is cost-effective if you can have one machine tender per machine.

China manufactures many things but that's not the key part of the value chain. iPhones are manufactured in China (and elsewhere in Asia but Apple in Cupertino is the trillion-dollar company, not the actual manufacturers.
The key parts are R&D, design, intellectual property, engineering talent. The question is, how well are Chinese organizations doing in those capacities in regard to robotics. My impression is that the answer is, quite well.
The focus on manufacturing is (in many cases) a twisted approach of economics. In the mid-20th century the West did very well with mass production. It was an innovative technology at the top of the value chain. But in early-to-mid 21st century, it's (often) an old, ~commodity technology and the ROI is poor. It's also physically not good for workers in many cases. When looking for economic growth you want to aim for top of the value change, for the future, not what was done 70 years ago - it won't work the same way economically anymore. In economics, you can't return to what worked before.

This was pretty much my conclusion while reading the article too.
Just to extend your point - chinese car manufacturers are not only producing more cars, they're innovating at a faster pace too. While I'm not an expert, there is enough and more on social media around this. Eg: https://x.com/dhh/status/2113500613082329576?a=fscIadYr4U1xm...
