RoPod/Tutorials/ROS installation

Get familiar with ROS

The Robot Operating System (ROS) is a framework for writing robot software. ROS uses concepts like nodes, topics, messages, etc. Get familiar with them by searching on the web. You can start reading at: http://wiki.ros.org/ROS/Concepts

Install ROS

ROS have several distributions (versions). Install ROS kinetic distribution, which is the one compatible with ubuntu 16.04. Follow the instructions on this webpage.

(This is not valid/ to be checked)Then, install roslaunch, which will be useful when launching multiple ROS applications from packages.

sudo apt-get install python-roslaunch

To test the installation, run in a terminal the ROS core:

roscore

Then in another terminal you can type:

rostopic list

You should be able to see at least the following:

/rosout
/rosout_agg

You can get familiar with ROS using the tutorials for beginners available at http://wiki.ros.org/ROS/Tutorials.

Get familiar with catkin workspaces, which will allow you to build a ROS node in the future. Moreover, get familiar on how to run a ros node.

If you already cloned the ropod-project-software in your home directory, then you should be able to compile the software now:

cd ~/ropod-project-software/catkin_workspace
catkin_make

In the next part of the tutorial we are going to see how Matlab and ROS can communicate.
