<!-- Now we can start using the macros included above to define the actual HyQ -->
<!-- The first use of a macro. This one was defined in trunk.urdf.xacro above.
A macro like this will expand to a set of link and joint definitions, and to additional
Gazebo-related extensions (sensor plugins, etc). The macro takes an argument, name,
that equals "base", and uses it to generate names for its component links and joints
(e.g., base_link). The included origin block is also an argument to the macro. By convention,
the origin block defines where the component is w.r.t its parent (in this case the parent
is the world frame). For more, see http://ros.org/wiki/xacro -->
