I've recently added a forum section dedicated to hacking the Roomba vaccum cleaner (and it's competitors once they start to appear). Please visit the Roomba & Competition forum section and share your hacks. My current hack will be a custom modification of the Bluetooth control hack recently covered in Make Magazine's blog. This is the hack that adds a wireless interface to the (newer) Roomba's serial interface, as seen on the Make Magazine blog.
Here's the link to the main Robots.net forum .
