The other things you could do are:
1-Get a good programmer that doesnt need testing! Testing is only for those who cant get it right the first time! (little programmer joke there, ignore if you dont get it).
2-Have your programmer make the adjustments necessary (as the difference between the shipping day and competiton day are hopefully not huge), and test on the practice day!
3-Do all your programming in the 6 weeks! My team is having myself and one other person do all the programming, just using a multimeter, the controller/IO, some speed controllers, and a laptop computer. We think that we can get 75% of the job done by the end of today, with only things like arms and alternative mechanisms left. It also did help that our EDU bot was used exclusively from the day we recieved it by the programming team to get a final version of the drive system complete. (complete gradient 1 stick control!).
