Limelight
Vision wins matches. Without reliable vision, you will not compete effectively. In modern FRC gameplay, precise autonomous routines, consistent scoring, and accurate localization all depend heavily on your Limelight system functioning perfectly. It is a core part of your robot’s ability to understand the field.
Pre-Match Limelight Checklist (Must Do Every Match)
Before every match, perform a complete Limelight check to avoid catastrophic failures on the field:
Ensure Full Robot Connection Connect to the robot Wi-Fi and confirm the Limelight is detected in the network.
Check AdvantageScope Pose Estimation Open AdvantageScope and verify that your robot pose is being updated via the vision system (look for pose jumps when targets are visible).
Access the Limelight Web UI Navigate to the Limelight's web interface and visually inspect:
Live Camera Feed: Make sure the camera is pointed correctly and is not obstructed or blurry.
Target Lock: Verify the Limelight is correctly identifying.
Pipeline Selection: Confirm the correct pipeline is selected
Confirm Identification Accuracy The target box should be consistently locked on and stable. If it's flickering, jumping, or failing to detect, investigate lighting, focus, or exposure settings.
Failure to run this check can result in lost localization, missed shots, or an entire autonomous routine failing. Do not skip it.
