* If the robot wakes up to a MAKE ABS DATA error it's probably having trouble communicating with some of the position encoders on the motors. The ABSolute position encoders are backed up by a battery and they can get into a state where they don't work right, that's what's described in the previous links is to get them to cooperate. | * If the robot wakes up to a MAKE ABS DATA error it's probably having trouble communicating with some of the position encoders on the motors.

Six are on the six motors of the robot, the 7th is the giant heavy motor/gearbox assembly on the floor, and the 8th is simulated by an arduino hanging by the wires from the circuitboard inside the cabinet. I really need to clean up that wiring, and replace the 7th motor with the dual-encoder emulator arduino code branch | ||
