I respectfully disagree, Don. The Model T suspension is not what we would consider optimum for handling on today's roads, but it was great for the conditions of the time. It has a lot of travel, and it's a simple, reliable design.
As for a 4wd robot needing suspension....as far as I can tell, a simple 4wd skid steer robot is the best design for NOT needing suspension! it keeps at least 3 of it's four wheels on the in contact with the carpet when going over the bump, unlike 6wd and 8wd designs which have at least two wheels off in the air.
Also you might have the possibility of the bumpers dipping below the BUMPER ZONE during rough pushing play, which might not be wise.
