hello, Did you make any improvements compared to the RUclips tutorial? I see your Robot works very well. If I use 3D files on RUclips, will it be as good as your robot? -can you please provide more details about those 3 gears used, like diameter size, number of teeth and hole size., if you print it yourself can you share the 3d printing file Is that Okay ? - What 4 types of servo motors are there (180 degrees or 270 degrees or 360 degrees)? Thanks a lot 🥰🥰🥰🥰🥰
No improvements, just that I used esp32 instead of Arduino, and I asked Chet gpt how to smooth the ADC to reduce fluctuations in the value of the potentiometer. The gear was made using the GF GEAR GENERATOR from Fusion 360. It probably made the same gear ratio as the producer suggested, but I don't remember it very well. I looked up the gear file I created, but I couldn't find it. Instead, I'll write down the link to the picture of the gear. Sorry for not being helpful. I'm more foolish than I thought drive.google.com/file/d/1CbgmspCT43WojeAv_6dsY9LjwRB5jNNt/view?usp=drive_link
@@esp-el4do Really thank you very much. I have started printing the parts and will finish in 40 hours. I have 1 more question: -I think what range should the potentiometer be in before inserting and closing the controller and before loading the program. do i have to have potentiometer at a particular position when attaching to the controller body? Can you tell me how to position the potentiometer when assembling? Thanks a lot

love it, reminds me of the remote handling arms for nuclear fuel.
must be lots or uses like hand controlled manipulator for an rov.

Hii, I need help with the inverse kinematic solution to your robotic arm, can you help me with that
I just copied the project. I don't have the knowledge
What arm project is this?

저는 설명대로 하니까 모터가 덜덜 떨리던데 어떻게 해결하신거에요?
