## What it is
MAVROS is a MAVLink-to-ROS 2 gateway that exposes flight controller data (PX4, ArduPilot) as standard ROS 2 topics, services, and parameters. It also proxies between a ground control station, the flight controller, and multiple ROS processes over a single link.

## Use cases
- control a drone from ROS 2 without writing MAVLink code
- stream autopilot telemetry like IMU, GPS, and battery into ROS topics
- send arm, takeoff, land, and mode-change commands to a flight controller via ROS services
- upload waypoint missions and geofences to a UAV
- proxy MAVLink between a ground control station and multiple ROS nodes
- run software-in-the-loop drone simulations with PX4 or ArduPilot

## When to choose
- you build drone/UAV software on ROS 2 and need to talk to PX4 or ArduPilot
- you want standard ROS sensor_msgs instead of raw MAVLink
- you need to route one MAVLink link to a GCS and several ROS processes
- you want a plugin architecture to add custom MAVLink message handling

## When to avoid
- you are not using ROS or ROS 2 in your stack
- you need a lightweight MAVLink library without the ROS dependency
- your flight controller does not speak MAVLink
- you need ROS 1 support only (this targets ROS 2 Humble and newer)
