Real-time control in ROS and ROS 2. An image of Robot Operating System (ROS) running in Antarctica. The ROS ecosystem has its own recording service called Rosbag, but as of this writing, Rosbag had only recently been released for ROS2. We supported the ROS2 betas via the ament plugin, but that was before Open Robotics had a ROS2 package repository setup, which meant that the ament plugin built the ROS2 underlay from source, and it was predictably dreadfully slow. This example uses a virtual machine available for download at Virtual Machine with ROS 2 Melodic and Gazebo. The ros1_bridge package is installed on this virtual machine. summary: ROS2 Talker/Listener Example description: | This example launches a ROS2 talker and listener.
