Welcome to AirSim, a fork of AirSim which was abandon by MicroSoft and ported to UE 5 by Colosseum

Build Status

Ubuntu BuildMacOS BuildWindows Build

Looking for more performance?

The company managing this repo created the SWARM Developer System to help build, simulate and deploy single and multi-agent autonomous systems. Check it out here: SWARM Developer System

IMPORTANT ANNOUNCEMENT

Moving forward, we are now using Unreal Engine 5 versions but if you need to use not latest version please use the available branches: UE 5.3, UE 5.4 or newer if exist! If you want to use UE4.27, you can use the original AirSim.

Unreal Engine Version for Main Branch

The main branch of this repository only supports Unreal Engine 5.4 and 5.5 for now!

Currently Supported Operating Systems

Below is the list of officially supported Operating Systems, with full Unreal Engine support:

Windows

  • Windows 10 (Latest)
  • Windows 11

Linux

  • Ubuntu 18.04 (NO LONGER SUPPORTED. 18.04 is EOL so we will not be checking this anymore and GitHub doesn't support CI builds)
  • Ubuntu 20.04

NOTE Ubuntu 22.04 is not currently supported due to Vulkan support. If this changes, we will notify you here. If you want to use Colosseum on 22.04, we highly recommend that you use Docker.

MacOS

  • MacOS Sequoia (15)
  • MacOS Monterey (12)
  • MacOS (11)

NOTE MacOS support is highly experimental and may be dropped in future releases. This is because Apple continually changes their build tools and doesn't like 3rd party developers in general. There are ongoing discussions to remove this support.

Introduction

Colosseum is a simulator for robotic, autonomous systems, built on Unreal Engine (we now also have an experimental Unity release). It is open-source, cross platform, and supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. It is developed as an Unreal plugin that can simply be dropped into any Unreal environment. Similarly, we have an experimental release for a Unity plugin.

This is a fork of the AirSim repository, which Microsoft decided to shut down in July of 2022. This fork serves as a waypoint to building a new and better simulation platform. The creator and maintainer of this fork is Codex Laboratories LLC (our website is here). Colosseum is one of the underlying simulation systems that we use in our product, the SWARM Simulation Platform. This platform exists to provide pre-built tools and low-code/no-code autonomy solutions. Please feel free to check this platform out and reach out if interested.

  • Ubuntu 18.04 (NO LONGER SUPPORTED. 18.04 is EOL so we will not be checking this anymore and GitHub doesn't support CI builds)
  • Ubuntu 20.04

NOTE Ubuntu 22.04 is not currently supported due to Vulkan support. If this changes, we will notify you here. If you want to use Colosseum on 22.04, we highly recommend that you use Docker.

MacOS

  • MacOS Sequoia (15)
  • MacOS Monterey (12)
  • MacOS (11)

NOTE MacOS support is highly experimental and may be dropped in future releases. This is because Apple continually changes their build tools and doesn't like 3rd party developers in general. There are ongoing discussions to remove this support.

Introduction

Colosseum is a simulator for robotic, autonomous systems, built on Unreal Engine (we now also have an experimental Unity release). It is open-source, cross platform, and supports software-in-the-loop simulation with popular flight controllers such as PX4 & ArduPilot and hardware-in-loop with PX4 for physically and visually realistic simulations. It is developed as an Unreal plugin that can simply be dropped into any Unreal environment. Similarly, we have an experimental release for a Unity plugin.

This is a fork of the AirSim repository, which Microsoft decided to shut down in July of 2022. This fork serves as a waypoint to building a new and better simulation platform. The creator and maintainer of this fork is Codex Laboratories LLC (our website is here). Colosseum is one of the underlying simulation systems that we use in our product, the SWARM Simulation Platform. This platform exists to provide pre-built tools and low-code/no-code autonomy solutions. Please feel free to check this platform out and reach out if interested.

This project is archived, better to use https://github.com/iamaisim/ProjectAirSim which has better support.

Welcome to AirSim, a fork of AirSim which was abandon by MicroSoft and ported to UE 5 by Colosseum

Looking for more performance?

The company managing this repo created the SWARM Developer System to help build, simulate and deploy single and multi-agent autonomous systems. Check it out here: SWARM Developer System

IMPORTANT ANNOUNCEMENT

Moving forward, we are now using Unreal Engine 5 versions but if you need to use not latest version please use the available branches: UE 5.3, UE 5.4 or newer if exist! If you want to use UE4.27, you can use the original AirSim.

Unreal Engine Version for Main Branch

The main branch of this repository only supports Unreal Engine 5.4 and 5.5 for now!

Currently Supported Operating Systems

Below is the list of officially supported Operating Systems, with full Unreal Engine support:
