This is AI slop and the article contains some of the worst illustrations I have ever seen. Most do not make any sense mechanically. Here are the worst ones:

- The "orbiting threaded rollers" in figure 6 are not meshing with anything (not that they could, since they are orientated in the wrong direction).

- The ball of the ball screw in figure 7 deforms the screw and the roller screw "meshes" with a flat surface.

- The guy on the pogo stick in figure 14 is jumping himself rather than putting his feet on the stands of the pogo stick.

- In figure 16, a key penetrates the elastomer skin of the optical tactile sensor, destroying it.

- The gears in figure 20 touch perpendicularly.

Really, it is hilarious. This will teach me a lesson or two.

Is it? Now I feel bad for having posted it. I mean, I know some stuff but not enough to judge over all the content in this article. It's unfortunate but from glancing over I thought it was a comprehensive and useful resource. I guess I will just give up on the Internet or something like that.

		« Rotary Actuators (The "Reflected Inertia" Trap) », « Quasi-Direct Drive (QDD) — The "Cheetah" Approach « The pattern ‘something — The « metaphor » <qualifier> ‘ screams Gemini. Gemini seem completely unable to generate a section title that doesn’t follow this annoying pattern.

- Figure 3 has "elboly actuators" for the elbow joints (zero hits on Google for the term).

Could it be just the illustrations? I'm not knowledgeable enough to judge the text contents.

		Now that you mention it ... apart from the typo the style of the illustration has all marks of AI.

The YouTube channel linked is more of the same. Just the absolute worst slop

		Actually, most videos seem to be real, run-of-the-mill showcases of various actuators the company sells. However, the owner seems to have added quite stupid AI-generated preview images lately.
