I had a quick search for firmware and Robots. I think you might find some interests with people who own Sony Robot Dog: Artificially Intelligent roBOt - AIBO. It seems you can store the firmware which contains what the bot has learned, and hence his behaviour, on memory sticks. I am sure that some of these people would be interested to discuss there bot's behaviour and may be exchange there firmware...
I also think that some hackers like to play with bios and other firmware of old game consoles and old computers. They may be interested in finding discussion forums for this, although these may already exist.
Also check LEGO, the toy company, they have some kind of bots (http://mindstorms.lego.com/
) with which you can play with firmware.
New Subtopics could be "Bots firmware" with Lego Mindstorms bots and Sony aibo firmware as first subtopic, and "Old consoles firmware".
What do you think?
