Here's a
couple of
random candid pictures, not from last year, but the idea of a pit still is the same.
Basically, you want ample table space, somewhere to put a tool box/tool chest, somewhere to put your driverstation while not in a match, and some method to display your team paraphernalia. Make sure you "design" enough space to fit your robot and robot cart - and keep a lot of space open too; it gets cramped fast! Structures are fine, but remember that you're limited to 10'x10'x10', at most, and most places will provide less than that. I see that you're a MI team, so I assume most of your competitions are districts, which mean you might have significantly less than that. Plan accordingly.
