Can you provide me the link of code? Your google drive link is not working.
Thank you for reaching out,,Here is the updated link to the code: drive.google.com/drive/folders/1rxOCbWO1x9Hs2toU3SBtMzucu82wSFMP?usp=drive_link Thank you..
I'm guessing if you put the first pivot arm on top and added ribs to it, it might be more sturdy. then add ribs on the lower part of the second pivot. Just super glue some more plastic pieces to brace it more. Pivot control looks great but i cant imagine Z axis bending so much would make for accurate positioning. Maybe within a 1/2" inch. Not bad though, this is probably how i would make my first one, except maybe more duct tape :) i've actually been wanting to make one but i know it would come out like this. so i've waited to figure out a more robust solution. The more sturdy i think about my design the more i think i need stronger stepper controls, which are costly. or high gear reduction for better accuracy.
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.
Why the music, cannot even follow
This is a well-known method of boosting the rpm of DC motors. The interesting fact is it works by decreasing the magnetic field that penetrates the rotor. Neodymium magnets are stronger, but the equivalent poles are much smaller and the air gap is much bigger than that of the original stator.
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

artistic wobbling lol
on that thread use a bearing, youll get less shake and greatly reduce the wear and tear
thank you.
How to get the components used in making it?
"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."
make it stable. it is shaking due to its poor structure.
"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.
what is the starting positon of the arm
Every starting point is a 90-degree point.
Hi..nice work. Would kindly share the code?
please refer to a link below simple-circuit.com/arduino-sensorless-bldc-motor-controller-esc/
@@bigrkei8896 Thankyou❤
❤wow!!! Nice video. Best of luck my friends
thank you
Very cool
Hi! Sorry what si the item between the motor and the sucker?
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)
The code you give just have to run on arduino uno right? Im using servo motor mg90 & mg996r, do u think it can move?
yes,, i used arduino uno and you can use mg90,mg996r ,, here(ruclips.net/video/to-BqdXs1zc/видео.html) is example
can you share the circuit schematic and program?
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.
Good great job Keep it up. Looking forward for more projects 🙏
thank you
where can i get all the details and the URDF file of this arm?
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.
Can somebody tell me where I can find the full code?
This is a 3 DOF robotic arm. The gripper/Tool isn't taken into account.
Exactly!
Nice video! I'd like to ask if it is possible for you to share the calculation of the inverse kinematics because the calculation done in the video was not clear enough.
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
