I have done it, but I don't remember the instructions. I do remember that the switch statement goes within the scope of the "func move { the switch statement goes in here}" because that move function is telling the Machine where to "go."

First, you need to create a Robot class (subclass of Machine). Then inside your new class you will create a move method. The switch (which is optional) would go in that move method.

You can also pass the challenge using only conditional (if) statements and no switch.
