drawer / Sensors & Controls
A plug-and-play smart camera widely used for FRC vision targeting and AprilTag-based localization.
where you actually meet Limelight
Limelight is the fastest path from no vision to working vision: power it, point it, configure a pipeline in a browser, and read the results over NetworkTables. Teams pick it when programming time is the scarce resource. The trade-offs you feel later are cost, a fixed hardware platform, and less freedom than a general coprocessor when you want custom processing.
Free and structured, and none of them need an account to read.

Sensors & Controls
Free, open-source vision software that runs on a coprocessor or Limelight for targeting and pose estimation.
read the entrySensors & Controls
A fiducial marker (like a simple QR code) placed on the field that cameras use to estimate the robot's pose.
read the entrySoftware
Tracking the robot's position on the field over time using encoder and gyro data (often fused with vision).
read the entrySensors & Controls
A sensor that measures rotation/position of a shaft, essential for closed-loop control and odometry.
