Hmm, when you say exactly like those do you mean the same general ideal, a turreted tank with wheeled, hover, and a tracked version or an exact copy of the model?
For future UGVs, we'd want whatever is required by the concept, really. This can vary, but so far the only UGV concepts we've got are reconnaissance and weapons platform.
Speaking of, we still need a small and light human reconnaissance drone. Very basic and cheap, no armour or anything. Just some cameras, a battery pack, a small radio antenna and a bunch of exposed wiring. Maybe different versions with different modes of locomotion -- i.e. a wheeled version and one with helicopter blades.
Quick question -- do you also UV/texture or just model? And do you animate at all?
