The KnowRob code has moved to its own repository at GitHub as part of an effort to make the development more open to the community. Several packages that have previously been part of the tum-ros-pkg repository or other private repositories have been made available in the knowrob_addons and knowrob_human repositories.
If you use the KnowRob binary packages, you do not have to change anything. If you use the source installation, check out the new repository using
git clone git@github.com:knowrob/knowrob.git
If you would like to stay up to date with recent developments of KnowRob, please subscribe to the knowrob-users mailing list that is used for important announcements around the KnowRob system.
