If my understanding of what you want is correct, having both plugged in would fry just about every circuit on the robot, and the battery and charger. I'm not sure if the charger plugged directly to the robot would work or not, but I know i have used a power covertor before to power the robot from a wall socket. Don't know if its legal in the pits or not though, and having two anderson connections seems not needed to me, since you would never want to have both plugged in at once.
