Be aware that you have a 45lb withholding allowance (normally this is 30lbs, but was increased to cut some slack to teams that lost a lot of time to weather).

What this means is that you can bring 45lbs of pre-fabricated/assembled stuff
to a competition, and simply bolt it on to your robot (anything that comes assembled does not count, like motors, or assembled gear boxes, but anything that is not assembled when you buy it counts towards the 45 lbs).

If your still working on your shooter, you can attempt to take advantage of this by removing your shooter and working on it apart from the robot, or by building parts to put on to the shooter when you arrive at the competition.
