5DOF Robotic Arm with Arduino and SG90 Servos

This is a simple 5-DOF robotic arm I designed as a quick demo project for school. Despite being developed rapidly, it works reliably and is great for learning, demonstrations, or small experiments in robotics.
 

The arm is designed to run entirely on an Arduino R3 or newer, using SG90 micro servos (standard or continuous rotation versions). Assembly is straightforward and uses M3 and M2 screws, with a bit of super glue where needed.
 

Cable management was not modeled in this version, as the focus was on functionality and speed of design rather than a polished final product. That said, I’ve included the Fusion 360 source files, so you’re free to modify, improve, or adapt the design however you like.
 

Visually, the design is loosely inspired by a video by FABRI_CREATOR, though all modeling and implementation were done from scratch.

If you have any questions, suggestions, or ideas for improvements, feel free to leave a comment — I’ll be happy to help!
