Robust active disturbance rejection

Now, very rarely do I ever post here about happenings unrelated to one the Z ongoing projects I have at any instant in time. However, this video, forwarded to me by a few of my peers, is simply too good to pass up.

It takes effort and generally alot of math and simulation to design a robust control system these days. As averse to math and simulation as I am, I generally haven’t embarked on any very control-theory heavy projects (I wouldn’t count Segfault as theory-heavy since the build has been more experimental in nature). The majority of my projects feature some kind of iterative design cycle – make once, break it, make again, and so on.

I suppose nothing can beat four billion years of practicing this methodology.


What do we see here? Essentially zero error, perfect damping, ultra-high bandwidth actuators, and what must be ultra low noise and accurate feedback.

Random Site Updates, Once Again

Every once in a while, I remember that other parts of my site exist besides the build posts. I’m going around and cleaning up the post categories and making sub-pages for more projects. I’ve also reorganized the project categories themselves, to better reflect what is in them.

You’ll notice the “Not Robots” section is gone. I’ve split off the vehicles into their own index page since I’ve built so many things that aren’t robots.

Pretty soon, I should have a more updated About page too. After all, if I keep directing people to it, I should actually consider putting something there….

Update: Hey, guess what’s live now? The About page.
