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.

When we started the ROS project back in 2007, our goal was to build an open robotics software platform for students, engineers, entrepreneurs, and anyone else to freely use and modify. In 2012, we took the next step by founding OSRF as an independent non-profit organization to pursue that mission, with responsibility for both Gazebo and ROS. Today, we see these tools used worldwide to teach concepts, solve problems, and build products in ways that we couldn’t have imagined at the beginning.
We couldn’t be happier with the size and breadth of the collaborative community that we’ve built together, and we’re grateful to everyone in the community for the roles that you’ve played.
You won’t be surprised to hear that it costs money to run OSRF. We employ a small team of amazing individuals, we operate an office in the Bay Area, and we run a suite of online services on which the community depends.
Since our founding, OSRF has enjoyed generous financial support from government agencies and private industry, for which we’re very grateful. We hope and anticipate that that support will continue in the future. But now, as we approach the end of OSRF’s third year, we’re trying something new: asking you, our users, for support.
If you rely on Gazebo and/or ROS in your lab, your startup company, your weekend projects, or elsewhere, please consider donating to OSRF. Your donation will support our people and infrastructure so that we can spend (even) more time developing and maintaining the software and services on which you depend.
As one example, if everyone who visits the ROS wiki between now and the end of the year donates just $2, we’ll have our costs covered for next year to manage, update, and host all of our online services, including the wiki. Donations in any amount are welcome. Give more, and we can do more.
Thank you for your support.

Utilizing OGRE, Gazebo provides realistic rendering of environments including high-quality lighting, shadows, and textures.
Generate sensor data, optionally with noise, from laser range finders, 2D/3D cameras, Kinect style sensors, contact sensors, force-torque, and more.
Develop custom plugins for robot, sensor, and environmental control. Plugins provide direct access to Gazebo's API.
Many robots are provided including PR2, Pioneer2 DX, iRobot Create, and TurtleBot. Or build your own using SDF.
Run simulation on remote servers, and interface to Gazebo through socket-based message passing using Google Protobufs.
Use CloudSim to run Gazebo on Amazon, Softlayer, or your own OpenStack instance.
Extensive command line tools facilitate simulation introspection and control.
A simple set of steps to get Gazebo up and running rapidly.
The best way to start using Gazebo is to run through the tutorials. These tutorials cover both basic and simple concepts through a series of exercises.

Gazebo will release a new major version every 6 months. Starting with Gazebo 4.0, releases will occur on the last week of January and July.
The following roadmap is a best guess at the available features for each version. At the time of release more or fewer features may be available.

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|
|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.
