The efficient handling of numerous in-vehicle sensors and their messages demands the use of multiple ROS2 nodes in a single vehicle. Additionally, in the cooperative perception paradigm, a significant number of ROS2 nodes can be required when a vehicle functions as a single ROS2 node. These ROS2 nodes cannot be part of a single domain due to DDS participant limitation; thus, different domain communication is unavoidable. Moreover, there are different vendor-specific implementations of DDS, and each vendor has their configurations, which is an inevitable communication catalyst between the ROS2 nodes. The communication between vehicles or robots or ROS2 nodes depends directly on the vendor-specific configuration, data type, data size, and the DDS implementation used as middleware; in our study, we evaluate and investigate the limitations, capabilities, and prospects of the different domain communication for various vendor-specific DDS implementations for diverse sensor data type., The inclusion of Data Distribution Service (DDS) as a communication middleware in ROS2 has proved its potential capability to be a reliable real-time distributed system. DDS comes with a scoping mechanism known as domain. Whenever a ROS2 process is initiated, it creates a DDS participant., Using ROS 2 to transfer large data over unreliable networks (e.g., Wi-Fi) can be a complex task that can lead to communication issues and packet loss and require a complex DDS configuration. At eProsima, we have worked hard to simplify configuration and enhance performance to address this challenge..
In the paper A Self-Driving Car Architecture in ROS2, researchers have presented the autonomous driving software architecture based on Robot Operating System 2 and evaluated the usability of a ROS2 node functioning as an autonomous vehicle during multiple automated driving scenarios., To address this problem, ROS1 will undergo a significant upgrade to ROS2 by utilizing the Data Distribution Service (DDS). DDS is suitable for real-time distributed embedded systems due to its various trans-port configurations (e.g., deadline and fault-tolerance) and scalability., Connext® DDS has been designed to provide throughput that both scales with payload size and delivers very low latency. But rather than talk about it, we wanted to show you how Connext performs in real-world conditions. This blog will walk you through recent tests on open-source ROS 2 benchmarks., The efficient handling of numerous in-vehicle sensors and their messages demands the use of multiple ROS2 nodes in a single vehicle. Additionally, in the cooperative perception paradigm, a significant number of ROS2 nodes can be required when a vehicle functions as a single ROS2 node., Camera images and regions of interest come from a rosbag recorded during a test drive with the Autoware simulation and Autoware AD software stack. Note: In a realistic scenario, the image publisher and the RoI publisher would not be located on the same node., As our main focus of the evaluation is how the latency characteristic behaves while communication happens through varieties of DDS implementations between diferent DDS domains, we assume the ROS2 system behaves similarly for the various DDS implementations..
