26 gauge sheet steel (available at most building supply stores) weighs about half as much as 1/4" polycarbonate per unit area, and weighs just a tad more than 0.1" thick polycarbonate (this thinner polycarbonate is also available at most building supply stores).
We prefer plywood, it's inexpensive, relatively light, rigid, insulating, and easy to work with. And you can screw wood screws into it.
And there isn't really much need to save weight on the bottom of a tall robot--one trick is to make the bottom as heavy as you want, which forces you to make the top of the robot lighter, and thus you have a more stable robot. Robots tipping over might be an issue this year, even without defense being played.
