We change it up based on the robot's functionality. In 2015, our robot was simple so we only used one driver, since the only mechanism on our bot needed to work well as the driver moved around the field. This year, we used two, since our shooter mechanism worked independently of our driving.

Basically, if a feature or mechanism needs to work at specific times while moving (intake or A-defense manipulation for example), our base driver gets control of it. If it works independently (e.g. shooter or hanger), it's given to our copilot.
