There is no special integration between BFL and ROS, we just pull the BFL source code and compile it as a library. You can find a nice getting started guide on the BFL homepage . To use BFL from another ROS package, simply add 'bfl' to your manifest, and you can include the BFL headers you need. Wim -- -- Wim Meeussen Willow Garage Inc.
