AttributeError: 'Robot' object has no attribute 'version'

Hello, i'm trying to run the leg mechanism example using this command:

simmechanics_to_urdf LEGS_MECHANISM.xml --output xml

but i get an error about the attribute version from the robot. I could't find nothing similar in the `issues.

Traceback (most recent call last): File "/usr/local/bin/simmechanics_to_urdf", line 11, in <module> load_entry_point('simmechanics-to-urdf==0.2', 'console_scripts', 'simmechanics_to_urdf')() File "build/bdist.linux-x86_64/egg/simmechanics_to_urdf/firstgen.py", line 1871, in main File "build/bdist.linux-x86_64/egg/simmechanics_to_urdf/firstgen.py", line 175, in convert File "build/bdist.linux-x86_64/egg/simmechanics_to_urdf/firstgen.py", line 202, in generateXML File "/opt/ros/melodic/lib/python2.7/dist-packages/urdf_parser_py/xml_reflection/core.py", line 584, in to_xml self.write_xml(doc) File "/opt/ros/melodic/lib/python2.7/dist-packages/urdf_parser_py/xml_reflection/core.py", line 577, in write_xml self.XML_REFL.add_to_xml(self, node) File "/opt/ros/melodic/lib/python2.7/dist-packages/urdf_parser_py/xml_reflection/core.py", line 550, in add_to_xml attribute.add_to_xml(obj, node) File "/opt/ros/melodic/lib/python2.7/dist-packages/urdf_parser_py/xml_reflection/core.py", line 332, in add_to_xml value = getattr(obj, self.var) AttributeError: 'Robot' object has no attribute 'version'

I believe this is related to ros/urdf_parser_py#59

Hi @GiovanniBorre and @daniel-dsouza , sorry for the late reply. As @daniel-dsouza mentioned, this is an upstream urdf_parser_py issue. I will leave the issue open until it is fully solved by urdf_parser_py, in the meanwhile if you want to have a reference for a checkout of urdf_parser_py that is working correctly, you can refer to https://github.com/robotology/icub-model-generator/blob/3d61348ded9390e7d0e31057ebd09f8f439f7357/.travis.yml#L57 that is the checkout we actually use for generation of iCub robot models.

Btw the CI is failing for the same reason https://travis-ci.org/github/robotology/simmechanics-to-urdf/jobs/741344160
