This off season we are most likely going to work on team skill building. Things like programming, tool use, 6 wheel drive, etc. One project that we did a few years ago was a farming robot. It would drive around, dig a small trench, dispense seeds, and cover it back up with dirt. We live in a pretty rural area and there is an annual county fair which we displayed it at.
Also, you can look here for ideas:
