This is an example that shows how to use Rerun's C++ API to log and visualize ROS 2 messages (for the ROS 1 version, see here).
It works by subscribing to all topics with supported types, converting the messages, and logging the data to Rerun. It further allows to remap topic names to specific entity paths, specify additional timeless transforms, and pinhole parameters via an external config file. See the launch directory for usage examples.

This example is built for ROS 2. For more ROS examples, also check out the ROS 2 example, the URDF data-loader, and the ROS 1 bridge.
NOTE: Currently only
geometry_msgs/{PoseStamped,TransformStamped}
,nav_msgs/Odometry
,tf2_msgs/TFMessage
, andsensor_msgs/{Image,CameraInfo,Imu}
are supported. However, extending to other messages should be straightforward.
The easiest way to get started is to install pixi.
The pixi environment described in pixi.toml
contains all required dependencies, including the example data, and the Rerun viewer. To run the CARLA example use
pixi run carla_example
If you have an existing ROS workspace and would like to add the Rerun node to it, clone this repository into the workspace's src
directory and build the workspace.
To manually run the CARLA example, first download the CARLA bag and extract it to the share
directory of the rerun_bridge
package (typically located in {workspace_dir}/install/rerun_bridge/share/rerun_bridge
). Then, run the following command:
ros2 launch rerun_bridge carla_example.launch
Prior to opening a pull request, run pixi run lint-typos && pixi run cpp-fmt
to check for typos and format the C++ code.
