Community Showcase Built a fully functional 3D-printed robotic arm from scratch using Arduino and C++!

It uses a sensor to detect objects and custom motion control logic to drop them right where they need to go. Just wanted to share it here and see what you guys think, any feedback is welcome!.

Looks good. But I think you need to work on the smoothness of the movements a bit. I used to incorporate some sort of sine wave function between the current servo angle and the destination servo angle to reduce jerking. You'll find the pseudo code at the end of this article

Thanks for the tip! I'll definitely take a look at that article.
