Here is a repository we'll be keeping up to date for collada robots:
https://openrave.svn.sourceforge.net/sv ... ta/robots/
These robots are all publicly available in one format or another from the official websites.
The extensions used to define robot-specific information are defined here:
http://openrave.programmingvision.com/i ... ed:COLLADA
They are still in development, so there is no version number yet.
