A quick introduction to ROS programming

This section is devoted to explaining an easy ROS example with GoPiGo3. By doing this, we can put our robot to work quickly so that, in later sections, we can deal with ROS commands and tools in a practical way, applying such commands and understanding what they do.

This very simple example is based on the distance sensor in GoPiGo3. It consists of publishing sensor readings and accessing them from other ROS nodes.

Setting up the workspace

To start using contributed ROS packages or to create your own, you will need to have a workspace in which to put the code. The step-by-step procedure to accomplish such a task is as follows:

1. From a bash terminal, create a folder and initialize the...
