# Control System

## Control Hub

<figure><img src="/files/hQ0is5HyTX1pQrMk8btP" alt="" width="375"><figcaption><p>Control Hub</p></figcaption></figure>

The **Control Hub** is the brain of the robot. It runs what is know as the **Robot Controller Console**, which stores all programs, configurations, and log files.

Even when programming in the REV Hardware Client or a browser this is just acting as a tool to access the Control Hub's software!

## Driver Hub

The **Driver Hub** is how we communicate with the Control Hub when we're ready to run a program and control the robot. It functions similar to an Android phone and runs the **Driver Station Application** to allow communication.&#x20;

The Driver Hub connects to the Control Hub's Wi-Fi network to communicate.&#x20;

### Navigating the Driver Station Application

After setting the Driver Hub for the first time, you will have access to the Driver Station Application. There is a lot of information displayed by the Driver Hub so let's take a closer look.

While connected to a Control Hub, the application will appear similar to below:
