Re: Brownout Prevention?

There are plenty of good ways to prevent brown out.

On the electrical side, make sure the battery wire terminals are tight on the battery terminals. Use lock or star washers. The type of battery that come in the KOP have them included. Make sure that the screws holding the wire on the PDP are also tight. Any ability to turn them is bad. Also make sure the 6 gauge wire is crimped well. These loose connections will cause higher resistance in the whole circuit. I solved that problem on our robot and on other team's robots.

On the code side, if you're using TalonSRXs then you can use current limiting. The motors for drive will pull lots of current. So if you have the code write the motor output to 0 when the current is too high, the problem will go away and you won't notice the brown out symptoms.
