Please make a tutorial on this. Help the students who are eager to learn this, please. It is an earnest request.

Howdy.
Flippin' awesome.
In trade school we rigged an electro magnet to pull on the end of a steel 15 inch ruler. We connected a sturdy mosfet to drive the electro magnet. Finally we used an Omron PID controller to excite the mosfet. The ruler bending was sensed with a reflecting opto-diode-transistor unit. LTH-209-01.
The task was to get the ruler to bend as close as 1 mm from the magnet without snapping on to the magnet.
Really tricky. I seem to remember having reached about 2 mm but not closer. If I remember correctly I used only integration with a very large time parameter.
The setup was inherently very escalating. One could see the ruler sway getting closer to the magnet. And monitoring the controller output one could observe it swinging violently using derivation too.
Regards.

Can you add which sensor pad you use in this in the description please?

[JoseRodriguez-tocd]

que buen poyecto!!!  podria saber que usastes aparte de un arduino. usastes labview??

[elena]

how does it know the position, velocity, and acceleration of the ball?

Working on a similar project using a touchscreen for input, a Teensy 4.0 for CPU and Fuzzy Logic for the control algorithm.

Thumbs up but I wonder if the PID gains were calculated or determined by trial and error. Is there a model?

[jahirulislammonir]

What is stand name which is used in the middle of the board.... TIA

[abdallaomer]

Good project. .I also want to do the same one can you tell what the components that you used and the controller

[KatanaFlare]

Hey fellow cal poly bronco. I am also working on the same project for my controls class. Do you think you can help me with some of the coding? I'm having trouble transferring the numbers (that relate to the balls relative position) from the pixy CMUcam5 to the Arduino uno board. Would appreciate any help you can give and if you can get back to me at your earliest convenience. Thanks!

[alexandrosiii]

Can you share with me the documentation about this product?

[ankitbasera]

Sir i want to learn how to make it
Could you please guide me through

[MrsGamer]

Looks great! What kind of filter did you use? My program is already working, however, the program/servos are really "nervous" and I don´t know which filter to use.

[speedbuggyv]

OK, very cool, I assume the camera was on the arm above the plate tracking the ball?

[abdelrahimmaidat]

hi bro, i wanna do the same one in my final project please tell me all what i have to buy first

[omersar]

Haw can I find this system cod ? Can you say it, please ?

[Azarias]

what is the name of the thing on the center of the plate?

[patrice]

hello how is called the joint in the middle under the plate ?

For all you guys asking for details on this, can't you tell that the author is too busy showboating with all those fancy graphics? He'll never give up his secret sauce.

[ghislainmoreau]

What is the model of your servomotor? thanks
