hello, would you mind explaining how you determined the coordinates of the other two joints? what plane did you use to solve them. would you mind walking me through?

is the narrator AI voice?

robot drank a lot of coffee

Thx, very nice tutorial. New subscriber

if the camera detects when to move the platform based on how small it looks ( this is to bounce it) I assume u did it like that then would it be that the height change isn't big enough to accurately detect when to bounce the ball you would need an extra camera to detect distance well enough

Importance of Mathematics explained!

Your video deserves more like and view

The vidro is straightforward, simple and smooth, very well edited and the calculations are accurate. Also I love cats. New subscriber.

The build quality is amazinggg!!!

Thank you for video but at 8:20 the functions of [X,Y,Z] than before period at x,z plane when Y=0 , are different and how are derived and the angle theta not clear to get the rotation angle of two motors we would use as function of [d,f] or [X,Y,Z, L3].

Amazing work!

To bounce the ball wouldn't you need to code it in a way that identifies the changes in the pink ball size (moving closer or farther) and maybe put some marks on the glass platform to have the camera also identify the location and the altitude of that?

A great project, thanks for sharing.

Hi, I have recently created something similar, this video has been very helpful in understanding the maths behind how it works, much appreciated. My only comment was that at 5:26 you showed the maths for one of the other arms, I tried to calculate this myself and ended up with something very similar but had L(-sqrt(3)*b + a) on the numerator of the fraction instead (the alpha and beta are swapped). I was just wounding if this was a mistake or have I gone wrong somewhere? Thanks again

Incredible project, with a high technical level. Congratulations on your work, Greetings from Spain

How about using ML to train the control - w/o explicit "math" - by learning from sucesses and failures?

Japanese?

Impressive!

Why i am seeing PID in all electronic projects this is insane.

You can get FPS up to 120fps by playing with resolutions. Make sure 4 lane is enabled for faster transfer. Cool video and project!

Hi there, Thanks for the tutorial, Is there any book or source to recommend to learn inverse kinematics in general?

I wonder how you can resolve the delay of camera and fix it into the code. :D

use ping pong ball to slow dow ...your is hevy. Nice!

Awesome work my friend👍👏 Thank you for sharing🌟 Cheers 🕊️

It is terrific awesome

Good video if you would ditch stupid clips added with annoying audio, it's totally unnecessary and adds nothing to video if anything it makes it worse

jumping may be hard because of the camera position, it hard to determine height

Great topic, thanks 👍

I love that you're using Blender

That's cool!

Super cool! I wonder how much more difficult this task would be if a second ball was introduced. I'm guessing it would be exponentially more difficult. Just guessing.

You need to adjust the vertical position of the ball by knowing the difference in its size. 60 FPS seems more than what is needed. This way, you can determine the vertical speed and also control the overshoot.

Very interesting and simple explanation with all the elements needed. Loved it and subscribed!

This is awespmeee

Great work! Good way of learning PID indeed.

Great stuff

Could you also post calculations?

Awesome work! Can you talk through your control algorithm next! You’re the man

Great video, excellent explanation of PID control. Beautiful design too.

At 3:40 you say that the center of the platform is in [0,0,h]. How do you know that the center will lie in the z axis? Is this an approximation for small tilt values of the platform or is it always true?

Hi! great video but I wondered if you could make all of your calculations available on your github because I am trying to find all of the platforms coordinates, but can't manage to find how.

Genius 😊

hello but that's a strange question, I became aware of your TH-cam channel a long time ago and wanted to ask if you already have a Discord server or if you would be interested in a Discord server? if you already own a discord server I would offer to support you

Oh, the robot butlers are close, I can feel it! LOL

Thank God, or rather, robotics. Now, all my life's problems can be solved by a ball balancing automaton.

This is what every bachelor robotics needs for his or her thesis. This was a pain to get my head around at the time. Thank you so much!

This is why the internet is a good thing

Do you have recommended orientations for printing the parts? I printed them all last night on my FFF printer but now I think I should redo them on the resin printer. I’ve ordered some engineering resin that should do well for these parts.
