How Fast Do Robots Think? #robot #coding #p5js #simulation

So Terramushi asks, "How often? " So for an actual physical robot, are the controls being pulled, updated, sent each second. Obviously, in an animated simulation, we have this concept of a frame rate. We could think about time in different ways. How does that work in physical reality? — Great question. So in physical reality, the standard for a humanoid robot now is that if you want a quote unquote good control, you want to update at a kilohertz. Now, I have my own opinions about that. That is definitely practically true with the methods that we're using. At the same time, some methods have been able to push it down to a few hundred hertz. But that's because the way that we're doing the calculations are probably like they're really tight. But if you compare contrast that to people, if you pricked my foot, I would not be able to react to that for about a 100 milliseconds. And yet I run just fine. So that's one of the things that I look at as a researcher. I'm like, oh, there's definitely better ways to do it. But a kilohz is like the standard. That's for modern controllers. for the Rayboard controller because it's so simple and you only have to push off at the right time and you make sort of smart decisions. I mean, you're probably talking on the order of 10 hertz range and you get away with it.
