This article describes the launch system for ROS 2, and as the successor to the launch system in ROS 1 it makes sense to summarize the features and roles of roslaunch from ROS 1 and compare them to the goals of the launch system for ROS 2.. The node is now running, and your publisher has started publishing on the /counter topic. 4. This is probably one of the most useful ros2 topic command line tool, youll use it all the time. In this tutorial, the nodes will pass information in the form of string messages to each other over a topic.The example used here is a simple talker and listener system; one node publishes data and the other subscribes to the topic so it can receive that data. These parameters have to be in the hardware nodes namespace (see franka_combined_control_node.yaml as a reference) and look like this: johnconn ( Jun 19 '20 ) rclpy.shutdown() This is the first thing that gets executed after you request to kill the node from the outside.
