Unlike the ROS-1 community, the ROS-2 community has begun to have some insights. There are good contributions from several research institutes and industries. Since ROS-2 only started its development in 2014, there is lots more information regarding ROS-2 research and tools to watch out for since implementing real-time systems—especially in an open source community—is one huge mountain to climb.

OSRF has been communicating really well with vendors that offer DDS implementation and contribute to the community. While ROS-1 has around 2,000+ packages in its repository, ROS-2 has around 100+ packages. The latest ROS-2 page is https://index.ros.org/doc/ros2/.
