drawer / Sensors & Controls
Free, open-source vision software that runs on a coprocessor or Limelight for targeting and pose estimation.
where you actually meet PhotonVision
PhotonVision is free and runs on hardware you may already own — an Orange Pi, a Limelight, a spare laptop — which makes it the choice for teams with more time than budget. You spend that time on setup: camera calibration, exposure tuning, and getting the coprocessor to boot reliably on a robot that gets power-cycled twenty times a day.
Free and structured, and none of them need an account to read.

Sensors & Controls
A plug-and-play smart camera widely used for FRC vision targeting and AprilTag-based localization.
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.
