Don't know anything about compasses, but you may be able to use mercury
switches to determine if your compass is horizontal. The 'bot can't be
moving when you try to read the switches, of course.
I once built a gravity sensor that triggered when something was no longer
horizontal (conducting pendulum inside conducting cylinder), but they
generally don't provide any info on what direction to move the platform to
make it horizontal again.
You could assume that whatever motion your robot just made was the one that
made it go off horizontal and then reverse it....
