Support launching gazebo sim to visualize vehicle

[Ryanf55]

• Works with ROS2 Humble
• Works with Gazebo Garden
• If you launch sitl with copter, a copter shows up in gazebo
• If you launch sitl with a plane, a plane shows up in gazebo
• If you move the vehicle in sitl, it moves in gazebo
• Each vehicle has an attached camera output with a corresponding ros2 camera topic

[srmainwaring]

There is an initial version of a bring-up package for an ArduPilot / microROS DDS / ROS 2 / Gazebo system here:

• https://github.com/srmainwaring/ardupilot_ros2/tree/wip/ardupilot-gz

The system can be brought up by a single launch file:

ros2 launch ardupilot_gz_bringup bringup_iris.launch.py

Run a interactive MAVProxy session:

mavproxy.py --console --map

The topics published by ArduPilot may be inspected with:

ros2 topic list
/ROS2_BatteryState0
/ROS2_NavSatFix0
/ROS2_Time
/clicked_point
/clock
/goal_pose
/initialpose
/iris/odometry
/joint_states
/parameter_events
/robot_description
/rosout
/tf
/tf_static

Docker image

Notes for running the ardupilot_gz packages on the docker image Dockerfile_dev-ros.

The image is configured for CI and requires additional packages to be used with Gazebo (in server only mode).

Summary

• Install Gazebo Garden.
• Install libsdformat12-dev.
• Install rapidjson-dev.
• Install libgflags-dev, ros-humble-ament-cmake-mypy, ros-humble-image-transport, ros-humble-image-transport-plugins.

The fact that the GZ rosdep keys will never resolve is actually pretty annoying. If we want to run this in CI, we could add the --skip-keys arguments, and then remove -r to enfoce our package.xml's work here.

Closing: we have not added a plane, but the two copter examples demonstrate the procedure for adding further vehicles.
