## Overview

MeddyBuddy combines operator-facing health-check prompts with autonomous MAVLink flight control and a return-flight handoff. The README describes Gazebo, ArduPilot SITL, and QGroundControl integrations; sampled scripts show the control and GUI subprocess calls, but not simulator configuration or live sensor acquisition. The GUI records completion markers, not measured health values. The STL and media assets support the physical payload and demonstration, rather than runtime processing.

Main entry points: [`scripts/gui.py`](https://github.com/lakhmanisahil/medical_drone/blob/main/scripts/gui.py) (MedResQ GUI), [`scripts/takeoff_waypoints.py`](https://github.com/lakhmanisahil/medical_drone/blob/main/scripts/takeoff_waypoints.py) (Waypoint mission), [`scripts/rtl.py`](https://github.com/lakhmanisahil/medical_drone/blob/main/scripts/rtl.py) (Return mission)
