Worlds

This topic provides imagery/information about the Gazebo Classic worlds supported by PX4.

The empty.world is spawned by default, though this may be overridden by a model specific world. Developers can also manually specify the world to load: Gazebo Classic > Loading a Specific World.

The source code for supported worlds can be found on GitHub here: PX4/PX4-SITL_gazebo/tree/main/worlds.

Model Specific Worlds

Some vehicle models rely on the physics / plugins of a specific world. The PX4 toolchain will automatically spawn a world that has the same name as the vehicle model if one exists (instead of the default empty.world):

The model specific worlds are:

• boat.world: Includes a surface to simulate buoyancy of the boat.

• uuv_hippocampus.world: An empty world used to simulate an underwater environment for the HippoCampus UUV.

• typhoon_h480.world: Used by Typhoon H480 (Hexrotor) vehicle model and includes a video widget to enable / disable video streaming. The world includes a gazebo plugin for a simulated camera.

• iris_irlock.world: Includes a IR beacon for testing precision landing.
