Wheels for lunar rovers can't be made like normal wheels.
We need to account for the conditions of mars and the moon. We have to think about the dust storms and craters. 3D Wheels is the next generation of engineers designing wheels for lunar rovers.
There are many designs that can come out of these wheels, many students have designed different types of wheels. All sorts of shapes, sizes, and whatnot can work for the grousers. We are pround, young, and aspiring engineers working to create the future of lunar travel by rover.
