I feel like it wouldn’t be as effective as you might hope, since all of the defenses are above ground rather than divots in the ground. A tri-star wheel would probably be stopped dead by things like the 4.5" bar or one of the 3" blocks.
That being said, see if you’re team can prototype one, possibly to scale and see how it goes.
That’s not really true. Teams have utilized tri-wheel designs in order to climb objects in the past. 1218 reached Einstein in 2004 with a tri-wheel designed to climb the center step.
