Thank you for reaching out,,Here is the updated link to the code: drive.google.com/drive/folders/1rxOCbWO1x9Hs2toU3SBtMzucu82wSFMP?usp=drive_link Thank you..

The center of gravity is not in the middle but rather too far back, which affects the precision of the Z-axis due to the weight of the two pivot arms in the front. The materials used in this video are mostly recycled, so there are many lacking elements. Thank you.

In this video, I removed the existing permanent magnet and discovered a neodymium magnet. I was curious to see if it would induce rotation when placed in the electromagnet state, which is the principle of a DC motor. Indeed, as you mentioned, there appears to be no magnetic field around the rotor, but despite minimal movement in the stator, it rotates slowly during the initial phase. However, as it gains momentum, it seems to accelerate significantly due to the powerful magnetic field of the neodymium magnet.thank you

@@bigrkei8896 may i ask the coding from the google drive is for which motion ?for the first or second motion ?

"Please refer to the link below for the code." I just set up a blog site for the first time, "This channel is about trying out basic things that I might not fully understand myself. It's a channel where I attempt to follow and understand various things blindly and try them out. If you have any questions, I'll do my best to answer within my knowledge limit and look up anything I'm unsure about." thank you.. code site => bit.ly/3PvgGPH

thank you fpr the code @@bigrkei8896

"I apologize for any difficulty I may have with speaking English. I will make an effort to improve. Thank you for your suggestion, and I'll consider uploading another video with speaking."

@@bigrkei8896 You don't have to speak English. Speak in the language you want. Then with the subtitles it will be better understood. Ps: Motors are not the problem, but belts.

thank you.

"The ball screw [3-meter-long] and 6mm guide were salvaged from items lying around the house, while the acrylic sheet was leftover from making an infinite mirror. The Arduino and CNC shield were used based on tutorials from RUclips. The stepper motors were given by my friend for testing purposes. The motivation behind this project was receiving 10 stepper motors and realizing I had enough leftover materials to put something together. Most of the materials used were recycled from existing items. Thank you."

"Yes, that's correct. There is no bearing on one side, so it's not smooth, and also, it's shaky due to weak fixation. Thank you for your interest."

you didn't get it - it's an artistic touch...

감사합니다.

Every starting point is a 90-degree point.

​@@bigrkei8896 Thankyou❤

thank you

it is a solenoid valve(electronic valve). picking up(when the air pump starts to suck up an item, pressure in suction cup can be lower than atmospheric pressure, so the item be stopped,, putting down( after valve is opened ,air enters the vacuum tube and the suction cup is seperated from the suctioned object)

yes,, i used arduino uno and you can use mg90,mg996r ,, here(ruclips.net/video/to-BqdXs1zc/видео.html) is example

I used free code on the internet, please refer to the link below. You need to modify some conditions to operate each motor, for example 1) initial motor forced drive times, 2) bemf debounce times, 3) pwm_min_duty, and minimize noise if possible. Here are the 3-item conditions for each motor applied in the video, old dvd bldc [ 1) i=9000, while(i>8500); i=i-30; 2) 60, 3)15 ] , hdd bldc [ 1)i=50,000, while(i<35,000); i=i-150; 3) 15 ],, it is most important you need to minimize noise, eg solder directly to the board, i hope you make it, feel free to ask me if you have any questions.simple-circuit.com/arduino-sensorless-bldc-motor-controller-esc/

@@bigrkei8896 can you show me the code that you modified, because I don't really understand the arduino program, in advance I thank you very much for responding to me

@@SSCchannel the code modified by me is almost same code that is on the internet, anyway if you give me your email address, i will email you it as an attached file.

thank you

After learning the basic principles of servo motors, I just applied the 2D inverse kinematics principle to the program (arm and wrist JOINT). All I did was convert pulses into angles and angles into positions to easily code the desired position. I don't have a URDF file. I collected all of this from books and the Internet bit by bit, understood it, and implemented it. All I have is the uploaded code and video.

Exactly!

yes, x=5,y=5 coordinates are inaccurate and Some other coordinates were also inaccurate in distant coordinates.I think calculation(just elbow and wrist) is right,, but I presume that the response speed of the servomotor is the problem or code is not optimized, i will test it again and i will share the test result with you.

@@bigrkei8896 I am looking forward to that. Thank you for the response

ruclips.net/video/RH3iAmMsolo/видео.html Great video for this calculation

please refer to the following link , i also learned the code from the link, embeddedthoughts.com/2016/04/19/scrolling-text-on-the-8x8-led-matrix-with-max7219-drivers/
