Controller Signal Problem In The Competition

Right now we are in a VEX IQ competition. In the match both robots started to moving out of order. We are thinking 2 robots signal mixed. Can you help us? Why did this happen? How can we solve it?

Thank you

You pair each controller to the brain using the blue cable. Connect them, put them in driver mode and verify that they work.

We label our brains with the team number and name, 23T Technomage, and the same thing on the controller. That way things don’t get swapped around.

For what it’s worth we also label the battery, battery charger, and the box, and the tray inside, some of my teams build close to each other and that helps with the whos stuff is this.
