Hello everyone, I have put together a tutorial on Stage Controllers here - http://www.ros.org/wiki/stage/Tutorials/Introduction%20to%20Stage%20Controllers. I have tested it on diamondback, I would guess that it will work on electric too - can someone please test it and confirm ? Any issues or suggestion to improve the tutorial etc is welcome.
