For those who are still interested in Robotics I'm happy to announce that the Robotics Stack Exchange site went into public beta on the 7th November 2012.
Although many Area 51 proposals related to Robotics have failed in the past, the latest combined Robotics proposal was created in April, completed the new 40 question definition phase in September, reached full commitment in October. The private beta site was created in late October and after an extension to help get it into shape, went public.
The final push for committers was completed with support from a dozen or so people here on Electronics, so hopefully the site will be of interested to other EE regulars. Robotics certainly appreciates the contribution already made by EE regulars.
If you are interested in Robotics and think you could contribute towards making the beta a success, we would love to see you over on Robotics. Whether you are an expert willing to lend your expertise or a hobbyist with questions to ask, I think the new Robotics site will be a great resource and I look forward to seeing people there.
