Worlds Vex IQ Game Challenge Field Setup

Will the VEX IQ Challenge Fields be elevated or on the floor or a combination of the two at Worlds? If elevated, how high will it be? We currently practice with the field on the floor and competed the same way at all our tournaments in our state. Today, we began practicing on our knees, just in case.

At World Championship, the VEX IQ Challenge game fields will be elevated on risers that are 18" high.
