In this video and the next one, we will apply what we have learned about FlexBE states to program a state that controls the conveyor belt in our factory simulation.

Before programming a FlexBE state implementation, think carefully about its design:

• • •  What should happen when our state becomes active?
    •  What interface should my state have to be used in a state machine?
    • What outcomes can result from our state?
    • What parameters should it have to be configured for a behavior?
    • What data does it need to execute, and what data does it produce? This defines the input and output keys

A FlexBE state is implemented as a Python class that implements the state Lifecycle:

• • • It is important to properly document your state.
    • You have to implement the different functions in the state Lifecycle.
