Gazebo Sim is an open source robotics simulator. Through Gazebo Sim, users have access to high fidelity physics, rendering, and sensor models. Additionally, users and developers have multiple points of entry to simulation including a graphical user interface, plugins, and asynchronous message passing and services.

Gazebo Sim is derived from Gazebo Classic and represents over 16 years of development and experience in robotics and simulation. This library is part of the Gazebo project.

Features

  • Dynamics simulation: Access multiple high-performance physics engines
    through
    Gazebo Physics.

  • Advanced 3D graphics: Through
    Gazebo Rendering,
    it's possible to use rendering engines such as OGRE v2 for realistic rendering
    of environments with high-quality lighting, shadows, and textures.

  • Sensors and noise models: Generate sensor data, optionally with noise,
    from laser range finders, 2D/3D cameras, Kinect style sensors, contact sensors,
    force-torque, IMU, GPS, and more, all powered by
    Gazebo Sensors

  • Plugins: Develop custom plugins for robot, sensor, and
    environment control.

  • Graphical interface: Create, introspect and interact with your simulations
    through plugin-based graphical interfaces powered by
    Gazebo GUI.

  • Simulation models: Access numerous robots including PR2, Pioneer2 DX,
    iRobot Create, and TurtleBot, and construct environments using other physically
    accurate models available through
    Gazebo Fuel. You can also build a
    new model using SDF.

  • TCP/IP Transport: Run simulation on remote servers and interface to
    Gazebo Sim through socket-based message passing using
    Gazebo Transport.

  • Command line tools: Extensive command line tools for increased simulation
    introspection and control.

Install

For installing Gazebo, see the getting started guide. If you want to use libgz-sim as a library, see the installation tutorial

Usage

Gazebo Sim can be run from the command line, once installed, using:

gz sim

For help, and command line options use:

gz sim -h

Known issue of command line tools

In the event that the installation is a mix of Debian and from source, command
line tools from gz-tools may not work correctly.

A workaround is to define the environment variable
GZ_CONFIG_PATH to point to the different locations of the Gazebo libraries installations,
where the YAML files for the packages are found, such as

export GZ_CONFIG_PATH=/usr/local/share/gz:$HOME/ws/install/share/gz

where $HOME/ws is an example colcon workspace used to build Gazebo.

On Windows, gz sim (i.e. running both server and GUI in one command) doesn't yet work.
To run Gazebo Sim on Windows, you need to run the server in one terminal (gz sim -s <other args>)
and the GUI in another terminal (gz sim -g <other args>). Remember this when reading through
all Gazebo Sim tutorials. Also remember that Conda and install\setup.bat need to be sourced
in both terminals (as well as any changes to GZ_PARTITION and other environment variables).
