"how do I program it" is the first step. You have to install the preferred environment on your Programming Computer (which can also be your Driver's Station). Write the Code. Compile it.

At that point, you are ready to attempt communicating with the Robot.

Do the basic robot setup (battery, pdp, crio). Also attache a motor controller, and put a Volt Meter on the output. Alternatively, you can setup the pneumatic system (compressor, pressure sensor).

Program and setup the radio. Update the cRio firmware.

Establish communications with the robot (I suggested tethered for the first time until you are sure it works).
Deploy the code.
Enable the robot.

What you want to do with your code is energize the Motor Controller (without the motor attached), or enable the pneumatic system and hear the compressor start up. Have it cycle on and off (1 second on, 1 second off).

At that point, you have gotten code to run on your robot.

With Ethernet from your picture, it looks like your robot is running fine.
Does it not respond to your joystick?

Check the USB tab in the Driver Station (on the left-the tab with a USB symbol) to see where your joystick has been connected. For the basic LabVIEW project it should be in the USB 0 position, it should be green, and it should brighten whenever a button is pushed.

Yes, the bot is not responding to the joystick. The joystick comes up in USB 0, and I can see the xyz axis things. Do we need to write code in order for this to connect, or should the robotmain file work?

Check that your motor controllers for the left side are connected with a PWM cable to the roboRIO PWM 0 port, while the right side motor controller is connected to PWM 1. If you have two motors per side then use a PWM splitter on each side.
The default code assumes one motor per side and the left side motor controller connected to PWM 0 on the roboRIO, the right side motor controller connected to PWM 1.

The default project described in screensteps should just work.
The joystick will be in arcade mode y-axis is forward and back, x-axis causes turns.

P.S.
I should have asked what the status lights are doing on your motor controllers (and which model motor controllers you are using-white Spark ones?)?

I have imaged the roboRIO and set up the radio, but do I need to image or setup anything else?

Also, how would I write a basic code in labview so that I can use the joystick in the KOP?

LabVIEW for FRC and the FRC Driver Station

Have you done this yet:

IMHO: Make sure you can deploy code and have it run ("hello world" type program). Then you can figure out how to get input (joystick) and drive motors. I don't know Labview, but I assume you need to define the USB Joystick before you can start using it in your code. I believe there is a default joystick type drive that you can use to connect the joystick to your drive motors (which you also may need to define).
