Get a drivetrain up and running, period. Set a goal. Since you are behind the best goal to set at this point is to have a drivetrain up and running by mid-meeting Friday period. If you don't already meet on saturdays plan on meeting this saturday, perhaps even sunday. But no matter what get that drivetrain done. because if worse comes to worst you have somehting to ship in two weeks.

After the drovetrain is complete set a goal of 3-4 days to have some mechanism/function of your robot complete. Meet extra days/hours whatever is necessary to complete that goal. that way when February 24 rolls around you can put a functioning robot in a shipping crate. Best policy is generally (for your team) one system at a time.
