But why windows? Realtime OS needed badly.
* you have Linux Kinix Python libs and drivers.
* You can use a very minimal Linux distro that starts little to nothing else up
It'd probably be better than running on Windows, but still not as nice as running real time, or close to real time (e.g. having a small C, Go or Rust program that runs on a custom Linux image where it runs as init)
Windows is not a real-time OS. There is no reasonable expectation for it to perform as one in places where one is required.
In this case, what is required is only a "soft-real-time" OS, which even Linux can manage. But for this sort of project it is more usual to use a microcontroller.
Programming microcontrollers is, incidentally, much more fun than programming a big'n'sloppy desk OS like windows ... or linux.

Put the robot backboard at one end and the curved one at the other end, hold some sort of tournament ¯\_(ツ)_/¯
It’s great to see, too, because his content is awesome!
I'm also really impressed at the way that he uses the tablet to quickly and interactively generate diagrams in (mostly) real time while speaking. Sure, he could make a "cleaner" animation but doing it this way is just as effective and probably saves a ton of time.
Leaving this other reference https://en.wikipedia.org/wiki/Parallel_manipulator Inverse kinematics of parallel manipulators for the general case can get really hairy
what a great workshop! And how did he get his hands on that CNC machine? Is it only for personal projects or also for freelancing?
Not accounted for: industrial plasma cutter, welder, sheet metal bender, 3D printer, CNC mill to cut ball joints...
It would be seriously cool to use the speed of motion of the backboard to get extra control and, e.g., need to move it less.
But that would take a hard real-time system, and be correspondingly more fun.
[edit]
At very end it says it doesn't account for spin.
Don't get me wrong, I would have never been able to create something like this, I completely lack the engineering background. But like many of you, too, I'm sure, I've got a backlog of cool ideas for fun projects that I just don't get around doing any more.
But stuff like this hoop is inspiring nevertheless.
Take a look at Tech Ingredients. He involves his son in all his projects/videos:

I would say he's a better father than most because of the fun experiments he does with his kids.
Of course but luckily the first two don't apply to me. And that any form of time drain leaves you with less time is kind of tautological.

That's good for him. But not everyone is the same. For instance, a father who has three children, say aged, 1, 2, and 3 years old should probably find it more difficult to involve all of them in his hobby projects.
I do agree, though, that as your kids get older and more and more independent, the amounts of free time you have start getting bigger again...
What is there to downvote?
I used to have much more spare time (family, d'uh!) and so had more time to spend on fun project. Don't get me wrong: I wouldn't treat my family for anything in the world but what's wrong with being nostalgic every now and then when you see someone else realizing a cool project like this for which I certainly would not find the time these days?
Was the perception that I was implying that this is a trivial project that anyone could realize, even me, if only had some more time? I can't imagine that, unless the downvoters stopped reading at the three dots - otherwise it would certainly have been clear that I find the project admirable.
So, I don't get it.
I do understand the run-away effect that someone sees a downvoted comment that has, say, 2 downvotes already and then feels the urge to be part of the club and downvote it a third time. I know the temptation.
At least some people express their thoughts in their answer but from reading the replies to my comment, even when someone disagrees what (what they think) I meant, I get the feeling that they wouldn't have downvoted necessarily because they're simply expressing a different viewpoint.
But again, I wasn't talking about other people who might be able to involve their family into their projects. That's completely besides the point. Of course, everyone is different. I was talking about myself. I find it hard to see how my remark could be construed as an alleged statement about life in general. And it wasn't even a negative statement either.
So, before I start repeating myself too much, I sometimes don't get HN'ers. Plus, anonymous downvotes suck. I guess that is a general statement about life.
