How to Connect a V5 Competition Robot to the Competition Field

The Field Control System is the device that controls when all robots competing in a match start Autonomous Mode, and it also controls switching to Driver Control Mode.

Step 1: Connect the controller to the Field Control System 

  • Plug the Ethernet cord from the Field Control System into the V5 Controller.
  • Make sure that the controller and brain are both turned off when plugging in.

NOTE: The Ethernet cord should already be attached to the Match Controller. If it is not, ask one of the competition staff for assistance.

Step 2: Turn on the V5 Controller

  • Turn on the V5 Controller by pressing the power button.

Step 3: Turn on the V5 Robot Brain

  • Turn on the V5 Robot Brain by pressing the power button.

Step 4: Allow the V5 Controller and robot to establish a wireless connection

  • The look of the V5 Controller screen prior to syncing with the V5 Brain.

  • The radio signal icon will display in the top right corner of the screen while the V5 Brain and V5 Controller are connecting.
  • Once the V5 Brain and V5 Controller are connected, the radio signal icon will display signal strength in the top right corner of the screen.

NOTE: If needed, read the How to Pair the V5 Controller to the Robot Brain article from this knowledge base.

Step 5: Start the competition program

NOTE: If needed, read the How to Run a User Program through the V5 Controller article from this knowledge base.

NOTE: A program can also be selected via the screen on the V5 Robot Brain. If needed, read the How to Run a User Program through the V5 Robot Brain article from this knowledge base.


Additional Information: Troubleshooting

If you followed the steps above but your V5 Brain and V5 Controller still are not connecting, please try the following:


Additional Information: Competition Control Indicators

Disabled Mode:

  • A "pause" icon will appear when the V5 system is currently in Disabled mode.

Autonomous Mode: 

  • A "code" icon will appear when the V5 system is currently in Autonomous mode.

Driver Control Mode:

  • A "play" icon will appear when the V5 system is currently in Driver Control mode.


Optional: Utilize multiple controllers

  1. Plug the field control Ethernet cable into the primary controller (bottom photo).
  2. Plug one end of a smart cable into the primary controller (either port with the "#" icon will work).
  3. Plug the other end of the smart cable into the secondary controller (either port with the "#" icon will work).
  4. Power on the primary V5 Controller.
  5. Power on the secondary V5 Controller.
  6. Power on the V5 Brain.


Additional Information: Understanding the V5 Radio LED lights

  • Notice the color of the LED lights on the V5 Radio to gather information about the status of your robot.
    • A solid red LED indicates:
      • There is no radio connection between the V5 Brain and V5 Controller.

    • A flashing red LED indicates: 
      • An active connection between the V5 Brain and V5 Controller.
      • The V5 Controller is not plugged into a field control system or the V5 Brain is not running a user program.

    • A flashing green LED indicates:
      • An active connection between the V5 Brain and V5 Controller.
      • The V5 Controller is plugged into a field control system.
      • The V5 Brain is running a user program.
