ROS also provides some language independence between communicating nodes. The publisher can be written in Python and the subscriber can be written in C , or vice versa. Nodes can communicate with each other across a network of machines. Nodes on all other machines find the Master using an environment variable containing the hostname of the machine which has the Master.For example, a Python publisher can gather sensor data while a C subscriber does the heavy-duty processing whenever there’s data available. When nodes request to publish or subscribe to a topic they give only the topic name.One is a publish-subscribe mechanism wherein one node publishes that it will have data available. In the example illustrated here, raspicam_node publishes compressed video to the topic, /raspicam_node/image/compressed.A node which wants that data, image_republisher in our example, then subscribes to that topic.Anything that makes sense to go together as a module would go in a package.
It’s difficult to explain what’s available for ROS without also going over how things are structured.
