Check each wire between a speed controller and a drive motor. One of them is likely shorted to the frame, and there is probably another frame connection elsewhere. The big things to worry about are the cRIO case and the Axis camera.
Your drive motors aren't the biggest BaneBots, are they? Those are notorious for developing internal shorts between the case and one of the terminals, apparently due to debris left over from manufacturing.
