Probably my version of steering, called AAAS Steering (Annularly Arranged Articulating Segments). It’s a wheel that kinda looks like pizza slices (from the sides) which can roll left and right as the whole wheel rolls forwards/backwards. By combining the different rollings, you can turn like a normal wheel, but with less tyre wear and also turn a tighter circle. I’ve raised funding, patented and tried commercialising the invention. If I win the funding, I intend to make a set of courses around my experiences to encourage students like yourself to try and invent themselves.
