Command Module Question

[EndGamer]

My team is in its first year, and we are wondering about the command module, or, if that is not what it is called, the thing that you control your robot from at competitions. I would like to know how to make it, such as what needs to be on it, what cannot be on it, and any other helpful tips. All advice will be helpful. Thanks in advance!

Edit: i think that i worded this completely wrong. See my below post for clarification.
