Re: Safe Method for Purposeful Brown-out
If you're doing it as a bench setup (or can put the robot up on blocks), and are wanting to just check brownout response of the roboRio, you can use a variable bench supply to power just the roboRio while powering the rest of the robot with the normal battery. The main thing to be careful to do is tie the negative side of the power supply to the negative side of the battery to get a common ground reference (no need to go to the battery directly, you can get this from wiring to any black terminal of the PDP). The advantage of this approach is you only need a small (e.g. 20W) bench supply as all you are powering is the roboRio.
What this looks like:
RoboRio (+) -- Power Supply (+)
RoboRio (-) -- Power Supply (-)
PDP any spare (-) terminal -- Power Supply (-)
