Can nodes on different machines, with different ROS distributions communicate over the network when using message types in std_msgs or common_msgs? I am working to testing this, but if someone knows and gives the answer, I might save much time :) Thanks!

This has been discussed many times here on ROS Answers.

I'll search some duplicates, but to give you an answer already: yes, as long as the contents of messages has not changed, different versions of ROS 1 can exchange data.

In the meantime, could you update your question with the Q&As you'd already found regarding this topic?

I'm going to close this as a duplicate of (for instance): #q315600, #q104086, #q76279, #q364122, #q280349 and #q252109.

Note: I'm not posting this comment to be snarky or mean. It's just this is a well discussed topic, it has multiple accepted answers, they all state the same thing and using a search engine they are easily findable (I used Google, with appended to my query string: different ros versions communicate).

With over 58000 questions already, we should really try to avoid posting duplicates, as it will just lead to repeated discussions and duplication of effort.
