2013-05-27 17:17:53 -0500 | answered a question | new to open source First, I'd say you'll want to spend a LOT of time setting up and using the software so you know its operation very well. Once you feel you are really ready to contribute via testing, bug fixes etc you might want to look at these resources, http://www.ros.org/wiki/Get%20Involved http://www.ros.org/wiki/Get%20Involved/Handoff%20List While for some of the newest happenings in the ROS community have a look here, Hope that helps. |

2013-05-26 06:17:52 -0500 | commented answer | What is the difference between a topic and a message? Ah, it's the fact that different topics can share the same message type I was missing. Thanks. |

2013-05-26 03:23:50 -0500 | asked a question | What is the difference between a topic and a message? A very newbie question for sure, but I'm having a little trouble distinguishing between topics and messages. I understand that topics are the named "channels" published and subscribed by nodes and messages are the details of the data carried on the topics so they seem like pretty much the same thing. Can you ever have multiple message types sent across one topic? If not then why the distinction between the two? |
