It's really not. Try replicating the behavior of the GADDS in DOOM. It's not as straightforward as you think, because they stop whenever an actor intersects them vertically or horizontally. Horizontally makes some sense (though it should be up to the mapper), ROTT's don't. They carry any corpses, ammo, or weapons ontop of them and still keep moving, IIRC.

Pic related, It's one of three different examples in the wad. They have to be really small too, as actors will try to wander outside of their normal radius and appear to be "floating" on air. Which isn't what you want.
