If you replace the batteries before the battery failure alarm occurs, you can keep the robot on during the battery change to avoid losing the position of the encoders. But if the batteries have already failed, the encoder position is lost, and it no longer matters whether the robot is on or off during the battery change.
El segundo connector en el robot es para connectar la baterias nuevas antes de desconnectar la viejas, de este modo no hay necesidad de recalibrar el roboT
