By adding the stops low down on the wedges. If you have the stop just high enough on the ramp that the front wheels lose contact with the floor, it will acheive the same thing as having no stops at all, but reduce the chance that it will tip. The stops couldnt possibly stop 100% of the tippings, but they would reduce them. There will never be a way that you can eliminate all tipping.

Perhaps I should have worded that differently. What I meant was so that when a wedges gets under another robot, and the robot is travelling up it in some manner (either robot driving) it wont allow the robot to travel up the full incline of the ramp, therefore reducing the angle an which the robot is tilted, which reduces the chance its CG will extend beyond its supported area.
And beyond all that, most of claims to support wedges from a defensive point show them as a defense against "Bricks". Well, if its a brick it probably doesnt have an arm or a high CG, so if it tips, its definately not its own fault. The bots that do tip usually are ones with large arms or very high arms. Well if these bots are on a wedge, either the wedge is trying to force them out of position or a "brick" isnt the problem playing defence against the wedge. If its got a massive tetra carrying arm, its not a pure defensive bot, and if theres interaction between you and it, it is often the wedge bot trying to play last minute defense, not the armed bot. And in that situation it would most definately be the wedged bot's fault.
