Do you have a plan for controlling the claw? If you're adding another motor or other device to actuate it, do you think you can make it work quickly enough at the regional to be able to practice using your robot? Same with programming...sure, you can work on code without the electronics installed on the robot, but how will you make it work right once you put it all back together? Unless you have another whole robot to test the code with between ship and comp, you'll probably end up making it worse.

You might be better off finishing the robot as well as you can, and spend a few days practicing using it, and fixing any bugs you find in the code, and maybe getting it to do something in autonomous.
