## What it is
Gazebo Sim is an open source robotics simulator providing high-fidelity physics, rendering, and sensor models. It offers a graphical interface, plugin system, and asynchronous message passing for simulating robots and environments.

## Use cases
- simulate robots before deploying to hardware
- generate synthetic sensor data like lidar and camera images
- test ROS and ROS2 navigation stacks in simulation
- build custom simulation environments with plugins
- train and validate autonomous robot behaviors safely

## When to choose
- you need a full-featured robotics simulator with physics, rendering, and sensors
- you work with ROS or ROS2 and want Gazebo integration
- you need a GUI plus plugin-based extensibility for simulation

## When to avoid
- you only need lightweight 2D physics without robotics features
- you need game-style simulation rather than robotics-focused modeling
- you cannot build or install C++ dependencies on your platform

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, gui, plugin-system
- domain: robotics, simulation, autonomous-vehicles, developer-tools
- platform: windows, cpp
- tags: robot-simulator, physics-engine, sensor-simulation, ros, ros2, 3d-rendering, ignition-gazebo, physics, linux, macos
