Why Gazebo?

Robot simulation is an essential tool in every roboticist's toolbox. A well-designed simulator makes it possible to rapidly test algorithms, design robots, and perform regression testing using realistic scenarios. Gazebo offers the ability to accurately and efficiently simulate populations of robots in complex indoor and outdoor environments. At your fingertips is a robust physics engine, high-quality graphics, and convenient programmatic and graphical interfaces. Best of all, Gazebo is free with a vibrant community.

The Latest

Gazebo on Windows


After many long years, Gazebo has finally been ported to Windows. Communication between Windows, Linux, and Mac is also supported. The video below demonstrates Gazebo running in Windows on a virtual machine. An instance of gzclient running on the Linux host machine then connects to the Window's server. Objects can be inserted, moved, and deleted on either machine.

You can grab support for Windows on the default branch of Gazebo. Make sure to follow these install instructions. Or you can wait for the release of Gazebo6 on July 27th, 2015.

Gazebo uses semantic versioning, a package numbering scheme that specifies ABI/API compatibility between releases. A version consists of three numbers separated by decimal points: MAJOR.MINOR.PATCH:
  • MAJOR version changed when incompatible ABI/API changes are made
  • MINOR version changed when functionality has been added in a backwards-compatible manne
  • PATCH version changed when backwards-compatible bug fixes are released

Physics Engine Support

Gazebo 3.0+ supports the ODE, Bullet, Simbody and DART physics engines. By default Gazebo is compiled with support for ODE. In order to use the other engines, first make sure they are installed and then compile Gazebo from source.

Physics Engine Gazebo Version Availability Notes
ODE 1.9+ Binary,Source Default engine
Bullet 3.0+ Source Gazebo requires libbullet2.82, available in the OSRF repository and to be included in Ubuntu Utopic.
Simbody 3.0+ Source Simbody packages are hosted in the OSRF repository. Expected to appear in Ubuntu Utopic official repositories.
DART 3.0+ Source DART packages are hosted in dartsim PPA. DART is in the process of moving toward inclusion in Ubuntu.
We are developing a physics plugin framework to resolve dependency issues. Each physics engine will interface to Gazebo through a plugin, avoiding the need to compile Gazebo with support for each engine.



Gazebo development began in the fall of 2002 at the University of Southern California. The original creators were Dr. Andrew Howard and his student Nate Koenig. The concept of a high-fidelity simulator stemmed from the need to simulate robots in outdoor environments under various conditions. As a complementary simulator to Stage, the name Gazebo was chosen as the closest structure to an outdoor stage. The name has stuck despite the fact that most users of Gazebo simulate indoor environments.

Over the years, Nate continued development of Gazebo while completing his PhD. In 2009, John Hsu, a Senior Research Engineer at Willow, integrated ROS and the PR2 into Gazebo, which has since become one the primary tools used in the ROS community. A few years later in the Spring of 2011, Willow Garage started providing financial support for the development of Gazebo. In 2012, Open Source Robotics Foundation (OSRF) spun out of Willow Garage and became the steward of the Gazebo project. After significant development effort by a team of talented individuals, OSRF used Gazebo to run the Virtual Robotics Challenge, a component in the DARPA Robotics Challenge, in July of 2013.

OSRF continues development of Gazebo with support from a diverse and active community. Stay tuned for more exciting developments related to robot simulation.
