-During the setup phase, the Robot hardware is inaccessible.
-For example, `R.motors` is unavailable since enumerations occurs in the `init` function.
-In this phase you can configure how the Robot finds and configures hardware.

+During the initialisation phase, all hardware is accessible.
 If you have any hardware which must be initialised before the start button is pressed,
  the initialisation phase is the time to do so.
