Yes this field uses substantially less material than the
2004 BOM required.
I can see the caps acting as almost a ladder rung retainer (if the pipe were penetrating wood on both ends, then capped on the outsides)
I'll bet the box will house a battery powered portable and durable beacon for field use - or have something to do with the magnet trigger
I'll bet that 12x12 lexan is a pressure plate, possibly a base as in "baseball"
and the magnet will be used in a triggering device on that plate, wired up to something that would trip a feature?
those (2) 3x? 8' long boards seem like a pedestal thats capped with the 4x8 plywood and layered with the 1/4" to brace the penetrated PVC.
One bold prediction is the lack of large field objects might mean an abundance of game pieces. Man I hope the people who said baseballs weren't right.
I think were making some sort of basket or ladder thing on top of the very low (2 1/2" high maybe) pedestal to collect said game pieces.
this clear field is also a good indicator of 6 bots at a time, to give more playing room.
Although it's safe to assume this is enough equipment for you to build test features and not necessarily full playing field objects.
I think the chain link is just to throw us off.
BTW I just happen to have a purple piece of clear film, which I looked through at the BEHR yellow sample color on the white background, and it made no difference, it just gave everything a purple hue but i still saw yellow and white and everything else
