This post is about how to build an AWS Step Functions state machine and how you can use it to interact with IoT edge devices. In this case, we are sending a smoothie order to a "robot" and waiting for it to make that smoothie.

The state machine works by chaining together a series of Lambda functions and defining how data should be passed between them (if you're not sure about Lambda function, take a look at this blog post!). There's also a step where the state machine needs to wait for the smoothie to be made, which is slightly more complicated - we'll cover that later in this post.

This post shows how to build two simple functions, running in the cloud, using AWS Lambda. The purpose of these functions is the same - to update the status of a given robot name in a database, allowing us to view the current statuses in the database or build tools on top of it. This is one way we could coordinate robots in one or more fleets - using the cloud to store the state and run the logic to co-ordinate those robots.
