Arduino Based 4DOF Robotic Arm Control

Updated: Jul 2, 2021

In this tutorial we are going to do is a simple design an Arduino Uno based 4DOF Robotic Arm control using potentiometer. This project will be helpful for beginners who want to learn to develop a Simple Robot (Me arm) in low cost or just want to learn working with Arduino and servo motors.

This Arduino Robotic Me Arm can be controlled by four Potentiometer attached to it, each potentiometer is used to control each servo. You can move these servos by rotating the pots to pick some object, with some practice you can easily pick and move the object from one place to another. We have used low torque servos with metal gear here but you can use more powerful servos to pick heavy objects.
