While we're at it, I think it's worth a mention that you are allowed up to 3 Additional VRM units on your robot according to R48 of the 2016 Manual. If you do have a processing unit on your robot that requires more than 2A (but less than 20 due to the fuse on the PDP), that is a possible option. As many others have mentioned, DC/DC converters may also be of interest.

Honestly, if you have a processing unit on your robot that is constantly drawing more than 2A, it might be a good idea to ask yourself "is this worth the trouble?". Something to keep in mind that electrical engineering, especially on a mobile robot, usually has the challenge of working with the power you're given. FRC Robots have a pretty big supply of power going to them as is, do we really need more?
