Changes to how ROS 2 and Gazebo integrate

Starting with Jazzy Jalisco, we are streamlining how ROS 2 and Gazebo integrate. For every ROS 2 release, there will be a recommended, supported Gazebo release that goes along with that release. For Jazzy Jalisco, the recommended Gazebo release will be Harmonic.

To make it easier for ROS 2 packages to consume Gazebo packages, there are now gz_*_vendor packages. Those packages are:

ROS 2 packages can use the functionality in these packages by adding dependencies in package.xml, e.g.:

<depend>gz_math_vendor</depend>

And then using them in CMakeLists.txt, e.g.:

find_package(gz_math_vendor REQUIRED)
find_package(gz-math)

add_executable(my_executable src/exe.cpp)
target_link_libraries(my_executable gz-math::core)

Note

It will still be possible to use alternate Gazebo versions with Jazzy Jalisco. But those will not be as well tested or integrated with ROS 2. See https://gazebosim.org/docs/harmonic/ros_installation for more information.

New features in this ROS 2 release

common_interfaces

New VelocityStamped message

Added a new message with all fields needed to define a velocity and transform it.

See https://github.com/ros2/common_interfaces/pull/240 for more details.

Adds ARROW_STRIP to Marker.msg

Added new type of Marker, ARROW_STRIP, to Marker.msg.

See https://github.com/ros2/common_interfaces/pull/242 for more details.

image_transport

Support lazy subscribers

See https://github.com/ros-perception/image_common/issues/272 for more details.

Expose option to set callback groups

See https://github.com/ros-perception/image_common/issues/274 for more details.

Enable allow list

Added parameter so users can selectively disable image_transport plugins at runtime.

See https://github.com/ros-perception/image_common/issues/264 for more details.

Added rclcpp component to Republish

Users can now start the image_transport republisher node as an rclcpp_component.

See https://github.com/ros-perception/image_common/issues/275 for more details.

message_filters

TypeAdapters support

Allows users to use Type Adaptation within message_filters.

See https://github.com/ros2/message_filters/pull/96 for more information.

rclcpp

Type support helper for services

New type support helper for services rclcpp::get_service_typesupport_handle is added to extract service type support handle.

See https://github.com/ros2/rclcpp/pull/2209 for more details.

ros2cli

Added a --log-file-name command line argument

It is now possible to use --log-file-name command line argument to specify the log file name prefix.

ros2 run demo_nodes_cpp talker --ros-args --log-file-name filename

See https://github.com/ros2/ros2cli/issues/856 for more information.

ros2action

type sub-command supported

It is now possible to use the type sub-command to check the action type.

ros2 action type /fibonacci
action_tutorials_interfaces/action/Fibonacci

See https://github.com/ros2/ros2cli/pull/894 for more information.

rosbag2

Service recording and playback

It is now possible to record and play service data with the ros2bag command line interface.

This features builds on Service Introspection, which has been available since Iron Irwini. Service recording and display adds the ability to record service data into a bag file. And Service playback can play that service data from the bag file.

Record all services data:

ros2 bag record --all-services

Record all services data with all topic data:

ros2 bag record --all

Play service data from bag file:

ros2 bag play --publish-service-requests bag_path

See the design document for more information.

New filter modes

It is now possible to filter by topic type.

ros2 bag record --topic_types sensor_msgs/msg/Image sensor_msgs/msg/CameraInfo

ros2 bag record --topic_types sensor_msgs/msg/Image

See more details https://github.com/ros2/rosbag2/pull/1577 and https://github.com/ros2/rosbag2/pull/1582.

Added introspection QoS methods to Python bindings

It is now possible to instrospect QoS setting from Python bindings.

See https://github.com/ros2/rosbag2/pull/1648 for more details.

rosidl

Added interfaces to support key annotation

The key annotation allows indicating that a data member is part of the key, which can have zero or more key fields and can be applied to structure fields of various types.

See https://github.com/ros2/rosidl/pull/796 and https://github.com/ros2/rosidl_typesupport_fastrtps/pull/116 for more details.

rviz2

Added regex filter field for TF display

When there are many frames on /tf it can be hard to properly visualize them in RViz, especially if frames overlap. The usual solution to this is to enable and disable desired frames in Frames field of the TF display. Now it is possible to filter frames using regular expressions.

See https://github.com/ros2/rviz/pull/1032 for more details.

Append measured subscription frequency to topic status

It is possible to visualize Hz in the topic status widget.

See https://github.com/ros2/rviz/issues/1113 for more details.

Reset functionality

It is possible to reset Time using a new service or using the shorcut R.

See https://github.com/ros2/rviz/issues/1109 and https://github.com/ros2/rviz/issues/1088 for more details.

Added support for point_cloud_transport

It is possible to subscribe to point clouds using the point_cloud_transport package.

See https://github.com/ros2/rviz/pull/1008 for more details.

Feature parity with RViz for ROS

It is possible to use the same plugins available in the ROS 1 version.

  • DepthCloud

  • AccelStamped

  • TwistStamped

  • WrenchStamped

  • Effort

Camera info display

It is possible to visualize CameraInfo messages in the 3D scene.

See https://github.com/ros2/rviz/pull/1166 for more details.

Changes since the Iron release

common_interfaces

Added IDs to geometry_msgs/Polygon and PolygonStamped

Polygons are often used to represent specific objects but are difficult to rectify currently without any kind of specific identification. This feature adds an ID field to disambiguate polygons.

See https://github.com/ros2/common_interfaces/pull/232 for more details.

geometry2

Removed deprecated headers

In Humble, the headers: tf2_bullet/tf2_bullet.h, tf2_eigen/tf2_eigen.h, tf2_geometry_msgs/tf2_geometry_msgs.h, tf2_kdl/tf2_kdl.h, tf2_sensor_msgs/tf2_sensor_msgs.h were deprecated in favor of: tf2_bullet/tf2_bullet.hpp, tf2_eigen/tf2_eigen.hpp, tf2_geometry_msgs/tf2_geometry_msgs.hpp, tf2_kdl/tf2_kdl.hpp, tf2_sensor_msgs/tf2_sensor_msgs.hpp In Jazzy, the tf2_bullet/tf2_bullet.h, tf2_eigen/tf2_eigen.h, tf2_geometry_msgs/tf2_geometry_msgs.h, tf2_kdl/tf2_kdl.h, tf2_sensor_msgs/tf2_sensor_msgs.h headers have been completely removed.

Changed return types of wait_for_transform_async and wait_for_transform_full_async

Previously wait_for_transform_async and wait_for_transform_full_async of the Buffer class returned a future containing true or false In Jazzy, the future will contain the information of the transform being waited on.

Enabled Twist interpolator

Included new API to lookup the velocity of the moving frame in the reference frame.

See https://github.com/ros2/geometry2/pull/646 for more information.

rclcpp

rclcpp::get_typesupport_handle is deprecated

The rclcpp::get_typesupport_handle that extracts message type support handle is deprecated, and will be removed in a future release. Instead, rclcpp::get_message_typesupport_handle should be used.

See https://github.com/ros2/rclcpp/pull/2209 for more details.

Deprecated rclcpp/qos_event.hpp header was removed

In Iron, the header rclcpp/qos_event.hpp was deprecated in favor of rclcpp/event_handler.hpp. In Jazzy, the rclcpp/qos_event.hpp header has been completely removed.

Deprecated subscription callback signatures were removed

Back in Humble, subscription signatures of the form void callback(std::shared_ptr<MessageT>) and void callback(std::shared_ptr<MessageT>, const rclcpp::MessageInfo &) were deprecated.

In Jazzy, these subscription signatures have been removed. Users should switch to using void callback(std::shared_ptr<const MessageT>) or void callback(std::shared_ptr<const MessageT>, const rclcpp MessageInfo &).

rclpy

rclpy.node.Node.declare_parameter

The rclpy.node.Node.declare_parameter does not allow statically typing parameter without a default value.

See https://github.com/ros2/rclpy/pull/1216 for more details.

rqt_bag

Improved performance and updated rosbag API

There are some breaking changes in the rosbag2 API and Ubuntu Nobel libraries versions that required some changes to use rqt_bag.

See https://github.com/ros-visualization/rqt_bag/pull/156 for more details.
