Vex Robotics Design System is designed to be usable in a competition
setting with multiple robots on the field together at the same time.
The transmitter's frequency module and the matching receiver crystal
determine the control frequency for a robot. 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.</font></p>
<p align="left"><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Each
Kit gives you a total of 8 crystals- 4 different channels, each one
with a crystal for the transmitter and one for the receiver. </font></p>
