In this project we will see how to make an ESP32 Mecanum Wheels Robot which is capable of moving in any direction. This unique mobility of the robot is achieved by using special type of wheels, called Mecanum Wheels. The robot can be controlled via bluetooth with an application that you can use on both iOS and Android smartphones. Also, this project shows a simple breadboard circuit for beginner readers, and a printed circuit board for those who want a more useful prototype. Check out the video to see how it works…
The main equipment of the project is mecanum wheels. So how do mecanum wheels work? A Mecanum wheel is a wheel with rollers attached to its circumference. These rollers are positioned at 45-degree angle to the axis of rotation of the wheel. This makes the wheel exert force in diagonal direction when moving forward of backward. So, by rotating the wheels in certain pattern, we utilize these diagonal forces and thus the robot can move in any direction.
We need two types of Mecanum wheels, often referred to as, left-handed and right-handed Mecanum wheels. In the source code step, I will explain how the robot will move depending on the direction of rotation of the wheels.”
