Udacity recently made its self-driving car simulator source code available on their GitHub which was originally built to teach their Self-Driving Car Engineer Nanodegree students.

Now, anybody can take advantage of the useful tool to train your machine learning models to clone driving behavior.

In this article, I’ll explain:

  • What you can do with it
  • How to set up the simulator
  • Deep Learning driver example

What You Can Do with it?

You can manually drive a car to generate training data, or your machine learning model can autonomously drive for testing.

In the main screen of the simulator, you can choose a scene and a mode.

First, you choose a scene by clicking one of the scene pictures. In the above, the lake side scene (the left) is selected.

Next, you choose a mode: Training Mode or Autonomous Mode. As soon as you click one of the mode buttons, a car appears at the start position.
