【How to build your own Arduino-based Scara robot】

In this tutorial, we will learn how to build an Arduino based SCARA robot. I'll show you the whole process of building it, from designing the robot to developing our own GUI to control it.

1 Overview

The robot has 4 degrees of freedom and is driven by 4 NEMA 17 stepper motors. Also, it has a small servo motor for controlling the end effector or robotic gripper in this case. The brain of this SCARA robot is an Arduino UNO board paired with a CNC shield and four A4988 stepper drivers to control the stepper motors.
