Gazebo is an open-source 2D/3D robotics simulator that began development in 2002. In 2017, development forked into two versions: "Gazebo", the original monolithic architecture, and "Ignition", which had evolved into a modernized collection of loosely coupled libraries. Following a trademark obstacle in 2022 regarding their use of the name "Ignition", Open Robotics took the opportunity to switch the version names, dubbing the original fork "Gazebo Classic" and the new, modern fork "Gazebo". Gazebo Classic integrated the ODE physics engine, OpenGL rendering, and support code for sensor simulation and actuator control. In 2025, Gazebo Classic was discontinued and replaced with the modern fork "Gazebo".
The default physics engine Gazebo Classic uses is ODE, though other engines, such as Bullet, can also be used. It provides a realistic rendering of environments, including high-quality lighting, shadows, and textures. It can model sensors that "see" the simulated environment, such as laser range finders, cameras (including wide-angle), Kinect style sensors, etc. For 3D rendering, Gazebo Classic uses the OGRE engine.
