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.

[@bigrkei8896]

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

Great video for this calculation

[@kopisusu3781]

Can somebody tell me where I can find the full code?

[@alexsyaneyniiko3417]

The code you give just have to run on arduino uno right? Im using servo motor mg90 & mg996r, do u think it can move?

[@bigrkei8896]

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

Why the music, cannot even follow

[@lokeshwarrajm3686]

what is the starting positon of the arm

[@bigrkei8896]

Every starting point is a 90-degree point.

where can i get all the details and the URDF file of this arm?

[@bigrkei8896]

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.

hi do you have video on explanation on the code ?

[@bigrkei8896]

"I will soon create a video explaining the code and upload it." thank you.
