OP:
You would benefit from some of the knowledge gained at the Championship Workshops, particularly those by
Karthik Kangasabapathy and
JVN. WPI ThinkTank also has MANY other great presentations, yet John and Karthik both stress two things:
1.) Design within your team's capabilities
2.) Do ONE thing well rather than trying to "do it all"
Building your team up for success takes a LONG time in some cases due to student & mentor capability. In our case, it took 5 seasons; finally we were worthy of a #1 seed just this year. Finally, our robot moved every match. Finally, we were able to make our practice matches without major elements missing on Thursday. We still had our own set of issues to work through (no team has a maintenance-free robot), yet it was our drive and passion that got us through them.
You'll get there, keep at it!
And never forget -- sometimes, you DO need some luck on your side.
