I made this wheel so it wouldn't break like the other rovers so I thought and then I thought I can make an engine on the wheel and then whenever it needed to go somewhere it can just lift off the ground to its destination, but you might be asking right now how do you keep that much fuel? Well, I thought of an idea to melt the rocks of mars into lava, and then the engine has a covering so the lava builds pressure and then... BOOM! the rover lifts off the ground to its destination. The covering explodes but the rover automatically puts a new one on really fast and the rover can go to wherever the rover controllers want it to go.
