That is precisely why FIRST/IFI added the 7.2V Nicad battery. It keeps the controller running even if an external short or load brings the 12V down to zero.

You should do this experiment. power up your robot with both a 12V and the 7.2V battery installed. Now disconnect the 12V. Your controller will continue to operate until you either disconnect the 7.2V battery OR press the RC reset button.

You do not need a regulator.
