Is that the *initial* dimensions - or the *maximum* dimensions?
If it's just one of those things like "the robot must start off in a
box no bigger than 30x60x30" - then it can just fold itself up into
that space when they are doing the measuring - and stretch it's
legs outwards after the start.
Climbing a standard step (which is about 20cm) with a 30cm tall robot
seems pretty tricky to me.
Something like the "Shrimp" might do it...but the requirement to move
along a surface that's higher on one side than the other would be hard
for a Shrimp to manage.
I think the idea of a long legged robot would be the answer...especially
if the rules allow it to start off folded up into the 30cm height limit
and then stretch out to (say) twice that size to give it a chance to
climb a 20cm step.

So that's about US$620...that's quite a generous limit!
That'll buy quite a bit of Lego (at US prices) - so you could certainly
consider a dual-RCX design with a butt-load of Pneumatics (unless Lego
is vastly expensive in your part of the planet).
