There has to be a reason why the sheets are polycarb and clear. As has been mentioned, they are too thin to be used w/o significant reinforcement. They could be used to lower the coefficent of friction, but I dont think so since it isnt really that slippery. They can bend, but as has been pointed out, other cheaper things can be used for this. But you can see through them. That has to be a key point!

My first thought was a large wall (perhaps 8-10' tall) that you have to reach over, and while looking thru it, pick up something with a "shovel" bucket.

Then another idea hit (and I notice that some others here have had this thought too) that there may be a raised center area / ramp that bots have to drive under as well as up, makes a lot of sense. You would have to be ble to see the bot underneath it to reasonably drive it.

But suppose you have to get up to the top of the raised area / ramp where maybe only 5 bots fit, and in the top there is a sort of pit. It could be made of a piece of something rolled into a large tube (ie 2' diameter) and filled with "stuff/pasta" that you have to dig a game piece out of? This pit would reach "down" to the ground (they cant really make a pit in the arena floor, right?)

So you have to dig (ie shovel) a game piece out of the "pasta" and lift it up to the top of the ramp/raised platform or perhaps then lift it even higher onto a support or post or such.

Anyway, just some thoughts and frankly Im not sure I can see how this totally meets the clue. But maybe it gives others even more ideas (not like we really seem to be lacking actually).

PS the local Longmont Home Depot claimed on the phone to no longer carry treadplate. Also, the price for a 1 x 2' piece shown elsewhere is pretty much prohibitive! $28 for 2 sq feet, and we need 32 sq ft?
