DAGstronaut

DAGstronaut is an Apache Airflow 3.3 project with two physical behaviors. Its emote DAGs turn task outcomes into happy and sad rover reactions through success and failure callbacks. Its exploration DAG drives a micro:bit rover that detects obstacles with ultrasound, captures a photograph, and uses local Gemma 3 Vision to classify what it sees, explain the evidence, and recommend a response. Airflow then pauses at a human-in-the-loop decision, where a five-inch Flight Director Console lets a person authorize the rover's next movement.
