Hi Rosen,
in
http://openrave-users-list.185357.n3.nabble.com/Storing-custom-data-in-robot-XML-files-td4026227.html you've mentioned that it is possible to set Key-Value parameter pairs in Joints. Unfortunately I was only able to set them in COLLADA or directly in Python but not in the XML Format.
As I am currently changing my robot file very often, I was wondering, if it is possible to specify the parameters directly in the XML file.
Greetings,
