urdf_parser_py Exception with new transmission specification about urdfdom

[eacousineau]

Good find! I'll add a check when it's parsing the transmission object specifically. I will spend an hour on it tomorrow.
Can you post the URDF you're parsing so I have it to work off of?

And for a manual overlay, maybe you can run CMake such that it installs to your local site packages, something like:

cd urdfdom
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=~/.local
# Install all of urdfdom to local usr setup
make install

It looks like it might install it to dist-packages, though, so I can't speak to it working like that.

Thanks in advance!

We work with calvin[0].
I uploaded the fully generated urdf to [1].

Started work on it.
You can piggy back off of the devel or install-space for overlaying the install of the package, even though it does not use catkin:

cd urdfdom
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=$(dirname $(catkin_find --first-only))
make install

(This assumes that catkin_find --first-only will return a directory in your devel-space)

Tested it out with the following command:

python -c 'import urdf_parser_py; print urdf_parser_py.__file__'

Should print out to the directory you specified.

I've implemented the code, but it is not yet ready. I need to be test and debug it tomorrow: https://github.com/eacousineau/urdfdom/compare/feature;issue-22?expand=1
For the URDF you've posted, it looks like a straight dump from rosparam. Could you regenerate with the following comand?

python -c 'import rospy; open("/tmp/calvin.urdf", "w").write(rospy.get_param("robot_description"))'

Thanks!

[eacousineau]

I apologize, I was unable to work on it today. I will address it either tomorrow or Tuesday.

[v4hn]

I'm sorry for not answering in time.

At the moment I'm experiencing technical difficulties
much more severe than a failing python module (failing workstation).

I hope to get back to you soon!

I just uploaded the properly formatted patch to [0].
Thanks for your time.

Thank you! I finished up the tests and submitted the pull requests.

You can see the diff patch when it parses calvin and then spits it back out to a string: gen.patch
