This is a replacement for the wiki page http://wiki.ros.org/Robots as a portal for discovery of ROS robots and hardware components but should not replace either the technical documentation on the wiki, or the robots own website or homepage.
Are these drivers considered unstable/experimental and therefore not listed?
I'm glad you like it.
In our porting process we skipped any listing that had fewer than 3 sentences on their wiki page. As the Universal Robot page had a [broken link](http://wiki.ros.org/Robots/universal_robot) to a non-existant Portal page in the old Robots page so it was skipped when we ported. A contribution for that would be great.
When adding the robots to robots.ros.org it's also recommended that a standard developer entry point be added at `http://wiki.ros.org/Robots/<RobotName>` In this location for things like the Univeral Robot there could be references to the two different available drivers etc.
That would be great. Note that Pepper is [already there](http://robots.ros.org/pepper/) but I would encourage you to maybe add an embedded video or some more pictures and a fuller description to make the page more engaging as well as fill in some more tags. And the Romeo would also be a great addition as well.
And to anyone else who has a ROS robot that's not currently there. Please put together a PR for adding it as well. This is a site for community and by the community, we simply seeded it from the previous wiki content to bootstrap it.
