We're attaching the HDPE over the wood for a couple of reasons.
Firstly, we've got the extra weight to spare, so we thought why not.

Secondly, extra armour never hurts, especially when we don't have to worry about an active weapon, we want to keep maintenance costs down considering it's our first competing robot.

Thirdly, Bolts may often be lent out to young family members who want to get involved, so we think it's best it can survive multiple matches with as little damage as possible, so they get more enjoyment out of it

Fourth, we didn't think about the HDPE until after we built the wooden chassis.
