Week 16. Checking ROS topics

I already could raise the RADI container and I knew how to use Selenium to raise a test server. So a few steps of the integration were already done.

There were a few more things I needed to know. For example, ROS topics, the ones who were going to give me the robot position.

The problem is, I initially have no idea what a “topic” is. So this week my main task was getting to know a little about ros.

I learned quite a few things about these topics, for example:

1. They are unidirectional, and one or various nodes can publish messages in them. (publishers)
2. Other nodes may subscribe to them. (subscribers)
3. Each topic has a message format asociated
4. Topics have to be unique

This seems interesting, hope I can make some progress soon.
