The Robot Millennium A&D application is owned by Autodesk Inc. Full product details can be found on the Robot Millennium web site.
This application is suitable for basic interoperability, and it can export and import cis/2 files.
If you install Tekla Structures and Robot Millennium on the same computer, then a direct link can be used.
Currently only the EC3, LRFD, CM66, E32 and ANS design codes are available in Robot when using the direct link.
If you are upgrading to Robot 2012, you will need to uninstall Robot 2011 along with the Autodesk Robot Structural Analysis link. Then install Robot 2012 and the link again. This way you make Tekla Structures point to the Robot 2012 application.
