When I try to lunch hyq example with: $ roslaunch xpp_examples hyq_ex.launch

I got the error:

xacro: Traditional processing is deprecated. Switch to --inorder processing! To check for compatibility of your document, use option --check-order. For more infos, see http://wiki.ros.org/xacro#Processing_Order deprecated: xacro tags should be prepended with 'xacro' xml namespace.

Thanks for pointing this out. This has now been fixed in #3, specifically here: https://github.com/leggedrobotics/xpp/pull/3/commits/12d074a22182111d0f3292295c3d769c350373f6 .

To use this fix, either clone the repo from master (git clone git@github.com:leggedrobotics/xpp.git) or wait until version 1.0.4 has made it into the ros-kinetic debians (could take a few days).
