The VEX Robotics Design System is designed to be usable in a competition setting with multiple robots on the field together at the same time. Each robot operating at the same time should be on a different control frequency. There are 2 different kits, A and B, giving you a total of 8 more possible control frequencies.

Run multiple robots simultaneously.
A "must" for competitions.
Crystals come in pairs, one for the Tx, one for the Rx.

Overview

The transmitter’s frequency module and the matching receiver crystal determine the control frequency for a robot. The receiver will hear only commands sent by transmitters using the same frequency. However, a robot will also hear commands sent by every other transmitter using the same frequency, so you’ll need to make sure that nobody else uses the same frequency as you.
