I think at very least, the diagrams are AI generated too.

The rest of the website seems filled with just as much slop too...
Right. I'd noticed that the first image, of the harmonic drive, was wrong. The flexible ring gear can't have a disc closely attached; that would kill the flexibility that makes the whole thing go. In some designs, the flexible ring gear is just a ring. The inside of the ring has to be smooth. The elliptical plug is way too small; it has to fit the ring gear.
Harmonic drives are confusing enough. It's amazing that they back-drive at all.
Anything wrong in the text? I'm out of date in this area, and I was reading this as a nice catch-up. What else did they get wrong?

I wouldn't be surprised if article is actually AI generated summary from several sources.Guided by human.
It's a new phenomena. Recently got a book on agentic AI which looks like OpenAI docs with added generated water.
