Main Control Board Assembly
Error 31 indicates a 'Permanent Internal Error' where the main processor loses the ability to handshake with the robot's sensor array or drive controllers. This is a hardware-level logic failure on the Printed Circuit Assembly (PCA), often caused by a failed voltage regulator or a degraded flash memory chip that prevents the boot sequence from completing. Replacing the main board restores the central processing logic and communication pathways required for the robot to initialize.
