The finite-state machine is a Python/Flask web service running on Heroku. When initialized, the drone automatically connects with the smart contract and begins autonomous operations. The bot code communicates with the FedEx APIs usign HTTP.
We wrote a finite-state machine that extends the artificial intelligence of the FedEx SameDay bot. It turns the drone into self-owning infrastructure that earns FeX tokens by making deliveries and using those tokens to pay for its maintenance. The drone AI depends on the FedEx APIs to validate delivery jobs sent by users of the marketplace. The drone is programmed to manage its own repairs. The drone determines when it needs maintenance, and can decide to hire a technician from the FedEx Economy. The drone uses the FedEx APIs to locate a nearby FedEx office and arrange to meet the technician for repairs.
