Well, 166's pit is basically a miniature workshop - our crate opens up into a small section, a main section, and another small section. In the middle, we have a flip-up shelf with a vice on it, and a shelf for toolboxes and batteries underneath. Above it are some little cubbyholes that hold safety stuff, zip-ties, band-aids, etc. If it's hyphenated, we have it there. In the right side compartment, we have a list of our matches and the results, as well as hooks for tools and a stress reduction kit. On the left side, we have hooks for wrenches as well as a large toolbox with most of our tools. We store some coats behind the toolbox. All the crate's corners have pool noodles on them so nobody gets hurt.
In addition, on one side of our pits we set up a table. Stacking milk crates and plywood gives us room for plenty of things, including our USB printer and a monitor for displaying pictures, our safety glasses, the driver station and control board, our "silly argument of the year" (brownie edges vs center this year, center won, voted by visitors!), programming laptops, giveaways...and below it we store the KOP totes with even more tools and spare parts. Ironically, every time I can think of that we build this "wall", we end up helping the team behind it, and it makes it annoying to get from one pit to the other.
Basically, our pit's BA, easy to navigate, and wicked helpful. With all this stuff, we still have a wide area - I'd say maybe 6 ft^2 - to stand and work on the robot in.
You can kinda see it
here from last year at Atlanta. (177 was using it at the time)
