 Power from the battery goes through the master breaker and into a Power Distribution Panel (PDP).  The PDP distributes the battery power to the various circuits in the robot.  Each circuit should be provided with a snap breaker that is appropriately sized (5, 10, 20, 30, or 40A) for the circuit it will be powering.  The PDP monitors the current flowing through it so the robot computer can monitor the current drawn by each circuit.

+The voltage regulator module (VR or VRM) contains circuitry that takes the battery voltage (which varies according to how much current is being drawn at any given moment) and generates well controlled 12V and 5V outputs.  These outputs are used to power sensitive electronic devices such as computers and radios whose voltage must remain stable at all times.  The regulator uses a SEPIC switching circuit to step up the voltage if it is below the target (5v or 12v) and step down the voltage if it is above the target.  The step up/down function takes place so quickly that any variations in the battery voltage are not seen by the output device.
