CANController Area Network — the wiring/protocol that lets motor controllers, sensors, and the roboRIO communicate on one daisy-chained bus.

where you actually meet CAN
CAN is one daisy chain, and one bad crimp anywhere on it takes out everything downstream. You meet it when the driver station starts logging missing devices, when two motor controllers were flashed with the same ID, or when the terminating resistors at the ends went missing. Most “the robot randomly died” stories turn out, on inspection, to be CAN stories.
Free and structured, and none of them need an account to read.
