Once you have flashed a microSD card and you are connected to Erle-Brain you will be able to work with ROS! As simple as this! (Those steps are described on the Getting Started section of Erle-Brain)
Fortunately for you, an Indigo release of ROS is already installed in a trusty chroot.
The following ones are the sections you will find in this page:
You will find ROS installed in
/opt/ros/indigo/ but you will need to source the
setup.bash(You will need to run this command on every new shell unless you add this line to your .bashrc)
So the first thing you need to know is that there is a working space named
catkin_ws to work with ROS, there you will find a
src directory, if not create one:
cd ~/catkin_ws/ mkdir src cd src
There you are going to build your new packages! See how to manage the environment.
For a package to be considered a catkin package it must meet a few requirements:
The package must contain a catkin compliant package.xml file.
That package.xml file provides meta information about the package.
The simplest possible package might look like this:
my_package/ CMakeLists.txt package.xml
