description Microsoft AirSim Overview

Microsoft AirSim is an open-source, high-fidelity simulation platform originally developed by Microsoft Research to train artificial intelligence systems for autonomous vehicles and drones. The software operates as a plugin for the Unreal Engine, providing photorealistic 3D environments, realistic physics, and customizable weather conditions. By simulating real-world variables and sensor inputs, it allows researchers to safely test flight paths and driving algorithms before deploying physical hardware. The platform became a foundational tool in the robotics industry for validating machine learning models in controlled, virtual environments.

help Microsoft AirSim FAQ

What is Microsoft AirSim used for?

AirSim is an open-source simulator for drones, cars, and other autonomous vehicles, created by Microsoft AI and Research. It runs primarily as an Unreal Engine plugin and was designed for computer vision, deep learning, and reinforcement-learning research. [Microsoft AirSim repository](https://github.com/microsoft/AirSim)

Can AirSim work with PX4 and ArduPilot?

Yes. AirSim supports software-in-the-loop simulation with PX4 and ArduPilot, plus hardware-in-the-loop support with PX4. This lets researchers test flight-control software against simulated sensors and vehicles before using physical hardware. [AirSim documentation](https://github.com/microsoft/AirSim)

Which languages and operating systems does AirSim support?

Its APIs are available through C++, Python, C#, and Java, and the project provides Windows and Linux options. macOS users can build the simulator from source, while the repository also contains an experimental Unity integration. [AirSim repository](https://github.com/microsoft/AirSim)

Can I use AirSim inside my own Unreal Engine environment?

Yes. The AirSim Unreal plugin can be dropped into an Unreal environment and exposes vehicle control, cameras, sensors, weather, and world-object APIs. That makes it possible to test a drone or car in a custom 3D scene rather than only in a supplied demo world. [AirSim code structure](https://github.com/microsoft/AirSim/blob/main/ct_airsim.md)
