The photo above depicts the DARWIN Car which allows you to work with more advanced programming for DARWIN-op. The big picture problem is having DARWIN drive the car. Solving this partially or completely is important because it is an excellent method to train pledges how to work with DARWIN. This is a collection of the data for the car.

==== Information ====

This section gives important information and tips for working with the car along with photos and videos for further clarification. 
\\
\\
**Potentiometers**
\\
  *The two potentiometers on the handles are made for steering the car. Pushing the handles forward makes the car move forward and pulling them back causes the car to reverse.
  *The two free hanging potentiometers have another function. One affects the zero offset and the other one adjusts the sensitivity. They should be plugged into two analog channels on the controller.

**Wild Thumper Motor Controller**
\\
  *The motor controller that currently runs the car has been retired. The newest model the T'Rex controller has also been retired, however it can be found and bought. Sample code for the T'Rex and the Wild Thumper can be found here:

    *T'Rex: https://www.sparkfun.com/products/retired/12075

==== Final Words ====

This tutorial's objective was to provide insight into the workings of the DARWIN Car. The information provided should be optimal for the reader to gain an understanding of the car and results that should come out of the project.
\\
\\
Speculating future work derived from this tutorial, includes having DARWIN complete tasks in the car. In the big picture, the problem of having self-driving cars can be solved with this tutorial.
