in what cases nodelets be used?
I am working on a ros project in which my publisher node (say x) collects data from camera processes it and sends 7 commands according to the result and my subscriber(say y) receives these seven commands , processes it and gives me the result Could this process be done using nodelets. The important thing is to note that there are only 7 commands but they change according to camera image, so the publisher is sending these 7 commands repetitively but not in any sequence.
