No, we don't have any maximum dimensions, but we realize that in some microprocessors you can't allocate memory dynamically so you would need to set a maxsize in the code. This is OK and not considered premapping.
I would say 20x20 would be a reasonable max size. We will most probably not do any maze bigger than this since the robots should manage it in less than 8 minutes.
We don't have any max number of areas either, but maybe 5 is a reasonable maximum value here?
