Webots Tutorial: Line Follower Robot using epuck // Controller code in Python

In today's webots tutorial video, we are doing a fun project of line follower robot. A line following robot is a great way to get started with robotics and only requires level 1 coding skills.

We will start by setting up our environment in webots. Next we will add a robot from the webots library which is e puck and add IR sensors. Then we will write our code which is controller in webots in python. I will go over how to detect the line using IR sensors and use those values to make a line following robot in Webots.
