This is just meant to be informative, I doubt that this setup makes sense yet!!

Oh, and i should add that it doesn't need to be connected at all times. Just use it when calculating your power consumption.
It'll show how many amps the whole robot is drawing. And then you can do quick math on your battery to identify estimated time remaining.
Also, good idea to throw a voltage divider on the battery positive wire. And connect that to your ADC of the robot controller to monitor the battery voltage in ARC. You can use the "shutdown" command in ARC to shut'r down.
