Agreed. But it doesn't go viral as much. Every cool robotics research goes with a comment that says "it could be useful for disaster response in a post-apocalyptic world where the conditions have changed in such a way that only my robot can save us".

It can hold a considerable amount of weight then that may have application for areas where sand, snow or even rocks may be a problem
