The CARMAConfig repository stores the deployment-specific and vehicle-class specific configuration files (such as Docker Compose manifests, network configuration files, system parameters) for use with the different deployment environments (i.e. local development, real vehicle, simulation, etc.) that CARMA Platform supports. A detailed breakdown of how CARMA Platform treats vehicle configuration can be found on the Confluence page: https://usdot-carma.atlassian.net/wiki/spaces/CRMPLT/pages/886276097/Parameter+and+Launch+Design+for+Different+Vehicle+Configurations
Folders containing the name of a specific vehicle class (such as 'lexus_rx_450h_2019') contain vehicle configuration data that is specific to that class of vehicle and sensor suite (for example, the launch file for the sensors used on that vehicle). Additionally, folders containing the name of a specific simulation scenario contain configuration data that is specific to that simulation scenario. These folders also contain the Docker Compose files that will launch CARMA Platform with the appropriate configuration. These folders do not contain calibration information that is specific to an individual vehicle.
Some parameters are unique to individual vehicles such as precise sensor orientations or controller tunings. These values are stored separately from parameters that apply to classes of vehicles. A special folder structure is used for this purpose, an example of this structure can be seen in the example_calibration_folder directory. Calibration folders should be installed on the vehicle such that their vehicle folders can be found at /opt/carma/vehicle. It is recommended that this be done as a sym-link to a git repository so your vehicle calibration data can be version controlled.
The CARMA Platform requires that some files be located in the /opt/carma directory so they can be found at runtime. The example_opt_carma folder in this repository contains an example of this folder's structure though some files cannot be included in this repo due to size or license restrictions. Therefore, the installation instructions should be consulted for proper setup. The folder is presented here as a supporting reference and used by development setup scripts.
The current CARMA Platform system operates as a hybrid of ROS 1 Noetic and ROS 2 Foxy components. While all core CARMA Platform components related to connected and automated vehicle capabilities (communications, localization, routing, trajectory generation, etc.) and all real-world physical sensor drivers are built for ROS 2 Foxy, a small amount of ROS 1 Noetic content still exists within the system. To enable bi-directional communication between ROS 1 Noetic and ROS 2 Foxy portions of the software system, the ros1_bridge package is used. The ROS 1 Noetic content that still exists within the CARMA Platform system is described below.
With regards to the primary carma-platform repository, the following ROS 1 Noetic content still exists:
- The
rosbag_mock_driversandmock_lightbar_driverpackages, which serve as mock hardware drivers to support local integration testing. These are expected to be upgraded to ROS 2 Foxy in the near future. - The
carma_recordpackage, which enables ROS 1 rosbags to be recorded. This package is being preserved to enable legacy data analysis scripts to be used for system evaluation. Note that ROS 2 rosbag recording is also supported by the CARMA Platform system. - The ROS 1 rviz configuration in the
carmapackage, which enables rviz to be run natively when CARMA Platform is deployed on a PC with a ROS 1 Noetic installed to its desktop. This is planned be removed after all ROS 2 Foxy packages are upgraded to ROS 2 Humble. Note that the ROS 2 rviz2 is also supported by the CARMA Platform system.
Additionally, the carma-ssc-interface-wrapper repository contains the drive-by-wire driver and SSC packages that are used for CARMA Platform-supported vehicle classes. The packages for several vehicle classes (Chrysler Pacifica, Ford Fusion, and Freightliner Cascadia) are only available for ROS 1 Noetic. These packages are closed source, and the external company providing them does not plan to upgrade them to ROS 2.
Finally, the carma-carla-integration and carma-ns3-adapter repositories contain packages that are required for simulation deployments. These packages are all built for ROS 1 Noetic due to a dependency on on CARLA 0.9.10, which only exposes a networking bridge for ROS 1. In the future, when simulation-related repositories are upgraded to support a newer version of CARLA, these packages will be upgraded to ROS 2.
The table below helps visualize this described breakdown of ROS 1 Noetic and ROS 2 Foxy content across the entire CARMA Platform system for different deployment types.
The primary CARMA Platform repository can be found here and is part of the USDOT FHWA STOL github organization. Documentation on how the CARMA Platform functions, how it will evolve over time, and how you can contribute can be found at the above links as well.
