What is the official surface that the robots will be driving on? For instance, My team bought some foam tiles, but they came two sided. One side was flat and smooth, and the other side was rough. Which is it?
Thanks,

The official field surface can be found here. These official tiles are similar to many of the common foam tiles that can be found at retail stores.
