Actually, guard rails are over-rated. In 2001 we had guard rails and we were 4 ft wide. Some robots could still manage to climb over the guard rail and get stuck. Others that had low clearance could catch their frame on the rail and it would lift their wheels off the ramp so they were no longer making contact and then they would get stuck also. So, the only way to have fool-proof guard rails is to make them taller than any robot's clearance. Even then, if they do not line up properly to start up the ramp, they can ride up the guard rail and really get stuck.

Like I said to begin with, drivers need to practice driving their robot straight up a ramp.
