Same here.
We're weak on mentors- very little mech Eng, very little programming... great machinists though! This year we were going to experiment with a 4 bar- team put it to a vote and it won- and then the design headaches started.
I guess (from today's build session) we've scrapped the 4 bar and now have a simple arm that just goes up.
Oh, and square holes are easy:
