The key I see to the tri-wheel style obstacle crossing mechanism is that the distance from bottom of the wheel to the tri-wheel pivot, must be greater than the maximum height of the obstacles is has the cross(sort of obvious). Last year we asked to borrow a trolley from our school’s maintenance department/people and they gave us a 6-wheel trolley where each wheel was a very rugged 125mm Omni-wheel.
Why does school have to get in the way of more important things like FIRST? When would we ever need to know about the stuff there teaching in here? - Briansmithtown [more]
