You have a set of components. So write a simple program just to check if your IRF540 MOSFETs will successfully run your motors from your battery.
If they all work together then you can make something with them. Unfortunately those motors run far too fast to be used to drive the wheels on a bot without some gearing. Perhaps you could do something more interesting like making a bot driven by a propeller or two (Google "airboats" then add wheels). That's if the combination does work.
