## What it is
RotorS is a Gazebo-based simulator for micro aerial vehicles (MAVs/UAVs) built on ROS, providing multirotor models like the AscTec Hummingbird, Pelican, and Firefly. It includes simulated sensors (IMU, odometry, VI-Sensor), example controllers, worlds, and a joystick interface.

## Use cases
- simulate quadcopter drones in gazebo
- test drone control algorithms before flying
- simulate IMU and camera sensors on a UAV
- research multirotor state estimation
- develop and validate MAV controllers in ROS

## When to choose
- you need a ROS/Gazebo simulator for multirotor research
- you want simulated UAV sensors like IMU and VI-Sensor for SLAM or visual-inertial work
- you are testing control or planning algorithms for quadcopters

## When to avoid
- you need a modern, actively maintained simulator (targets older ROS versions like Kinetic)
- you simulate fixed-wing aircraft or ground robots
- you want a simulator without ROS dependencies

## Facets
- artifact type: library
- maturity: maintenance
- function: simulation, robotics
- domain: robotics, simulation, autonomous-vehicles
- platform: cpp
- tags: uav, gazebo, quadcopter, mav, ros, drone-simulation, linux
