In the autonomous phase of a match the robot operates without any human input or control. In the driver-controlled phase, the robot can receive input from up to two human drivers. ### Point-to-Point Control System -The _FIRST_ Tech Challenge uses Android phones to control its robots.

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. +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.

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.
