Thanks to all of your help, we're getting close to the official release of Diamondback. Eigen 2/3 rollout is complete and we have received many patches to improve compatibility on various platforms. How you can help: 1) We want to make it easier for new users to figure out what the common ROS tools are. We've put up a new "Tools" [1] page as a start, but feedback and contributions are welcome. We would also appreciate feedback on our "APIs" [2] page. In other words, "What do you wish the wiki helped you find out about better, and how?" 2) We are creating new robot 'portals' to help users of particular robot platforms. We would appreciate feedback on the current pages as well as your own contributed portals. Examples: [3], [4], [5] 3) Patches, bug reports, etc...
