That's what I got when I did the math on Saturday. Note that the robot does not need quite this much ground clearance to get on top of the rampart, because it is running up the ramp; this is similar to the front clearance needing to be less than 15" to get under the 16" low bar. Just how much is needed is a function of your wheelbase and how far your chassis extends ahead of the front wheel axle.
While we're designing with enough ground clearance to cross the ramparts on-center, we'll probably make our robot narrow enough to drive up the left side, and only have to worry about the steep drop on exiting.
