I didn't think it would be possible to combine tank treads with actuated caster wheels (omni-wheels). I was impressed with this demo. See how they get the mechanical power into the treads without obstructing forward or sideways rotation? See how the axles have to come in from the back and the front? Conventional outward axels would work with omni-ball wheels, but not treads. And treads are so much more capable. I'm not sure they even need to use slick plastic (nylon or teflon) treads like they have. And they certainly don't need to limit themselves to slick hard surfaces (like most omni-bots do). I bet it would do well on carpet, gravel, grass, and inclines--it just needs some grippy/sticky rubber knobby offroad treads.
