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. - Th…

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.
The pattern ‘something — The « metaphor » ‘ 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.

Really, it is hilarious. This will teach me a lesson or two.
From what I can understand this is the Robbie Dickson in question: https://www.huffpost.com/entry/lessons-from-a-serial-ent_b_9...
Nobody has a problem with companies using AI to edit articles, create images. But when even the writer is an AI persona, the trust factor gets destroyed.
I simply do not understand why you would ever prefer a fully humanoid robot as opposed to a humanoid torso on some other locomotion system.
Legged robots overall have more implementation complexity, spend energy just to idle standing up, but can go over much more varied terrain provided the controller is good enough. There are ways to adapt wheeled bases to different terrains (eg. larger wheels, whegs, RHex, rocker-bogies) but we know how to use legs to locomote over many terrains from personal experience, while the perfect wheeled/non-legged locomotion system perhaps remains to be designed.
There's also the way robotics is going toward data-driven methods, which in some forms (ie. imitation learning) require human teleoperation data. Here having the robot mimic the human form makes the mapping from human joints to robot joints easier (compared to other morphologies where you'd need to figure out how to best approximate a human motion with the joints/joint limits your robot has, though this is not impossible).
- I wonder, is it possible to give a reason to the flag?
- Is flagging the submission without comments the right way to go?
For me, it is important that slowly but surely it goes through that AI slop is not what is accepted here on HN. Yes to have whatever LLM helping with grammar, spelling, etc. but the content should not be the output of a one shot "write me a blog post about humanoid robot actuators" prompt.

Why not make a robotic chair? Why not build our environment out of specialized robots instead of using a hammer for everything?
> The "Zero RPM" Problem
> When a robot bends its knees to stand, the motor must constantly fight gravity. There is no skeletal structure to lock against. To an electric motor, holding a static load—known as stall torque—is the most punishing state possible.
Why not just add some kind of brake that can fully or partially lock the joint?

Right, but: 1. Asimov wrote that because he needed robots to be indistinguishable from humans for plot reasons. 2. We do 99% of our tool use with our arms and hands. We are already very good at building robot arms. We are getting better at robot hands. We can build robot legs, but they're very expensive and they pose a major safety risk for the robot itself and surrounding humans (because the robot can fall if there…
We can have optimized automation in warehouses/logistics, but if you talk to any site manager you learn very quickly that no one wants any downtime or impact to their operation to introduce new machinery or optimize traffic, etc. If it is not built with that from the start it's very hard to introduce it later on unless there is a very clear deployment path and cost structure.
And boy, robotics currently has any of those today. Sure, move those billions in to R&D. Time will tell.
