    First to build any machine you need to write specifications. What will it do, how will it be powered, etc.? Then make a conceptual design to verify that no laws of physics are to be violated. Then satisfy that the specs. can be satisfied. You may have to repeat some of these steps. Examine the interfaces to satisfy the intended use.
