Re: How are bellypans made?
12 mm birch plywood. Cuts nice with a table saw. Screw the electronics parts down with wood screws. Quick and easy. If you need to drill a hole, the shavings are non-conductive. We used it even back when we used to make the rest of the robot out of metal. We do sometimes do some cutouts or partial cutout/rib patterns with a router.
We like to have a solid surface on the bottom of the robot when there is any chance it could be tipped over and another robot could run into the bottom, like this year. I'm toying with the possibility of cutting a set of ribs out next year on a CNC router (if I can find access to one) and then fiberglassing it. It will depend on the game and on what the weight / cost / hassle trade-off analysis ends up saying.
