I agree that we probally have some sort of ramp, but the plywood numbers dont quite make sense to me.. the 1/2" plywoold should work as decking of a ramp, but why include the 3/4" ?
unless there is another structure that must be stronger than the 1/2"
Like others have said the luan is not structural, but neither is 1/4" plywood... robots could easily break that if contacted.
But also keep in mind these materials usually include some sort of half wall for the operators to stand behind as well as supports for it, so all of this most likely will not be going on the field... maby one of the 1/2" sheets is used for that. Also the pratice field they spec out usually is only half if that of the field.
