One phone is mounted onto the robot and is called the _Robot Controller_. The Robot Controller acts as the “brains” of the robot. It does all of the thinking for the robot and tells the robot what to do. It consists of an Android device running the FTC Robot Controller app.

A second phone sits with the team drivers and has one or two gamepads connected. This second phone is known as the _Driver Station_. The Driver Station is sort of like a remote control that you might use to control your television. The Driver Station allows a team to communicate remotely (using a secure, wireless connection) to the Robot Controller and to issue commands to the Robot Controller. The Driver Station consists of an Android device running the FTC Driver Station app.

### REV Robotics Expansion Hub
The REV Robotics Expansion Hub is the electronic input/output (or “I/O”) module that lets the Robot Controller talk to the robot’s motors, servos, and sensors. The Robot Controller communicates with the Expansion Hub through a USB connection. The Expansion Hub is connected to a 12V battery which is used to power the Expansion Hub, the motors, the servos and sensors. The Robot Controller typically has its own internal battery, which can also be charged through the USB cable connected to the Expansion Hub.

### What's an Op Mode?
During a typical FIRST Tech Challenge match, a team’s robot has to perform a variety of tasks in an effort to score points. For example, a team might want their robot to follow a white line on the competition floor and then score a game element into a goal autonomously during a match. Teams write “op modes” (which stand for “operational modes”) to specify the behavior for their robot.
During a typical FIRST Tech Challenge match, a team’s robot has to perform a variety of tasks in an effort to score points. For example, a team might want their robot to follow a white line on the competition floor and then score a game element (such as a ball) into a goal autonomously during a match. Teams write “op modes” (which stand for “operational modes”) to specify the behavior for their robot.
_Op modes_ are computer programs that are used to customize the behavior of a competition robot. The Robot Controller can _execute_ a selected op mode to perform certain tasks during a match.
