I originally thought from reading that you were going to mass market your Experimental Robot Platform. That being the case, I think it would be good to have a selection of your one-part suspension for different weight ranges since this platform is expandable and the weight will always vary. For example, less than 1 pound, 2lbs, 3-5lbs, 5-7lbs, 7-10lbs, etc. Also make them height adjustable for robots with different ground clearances. I'd buy a set!
