hector slam on turtlebot, how to use?

edit

Hello,

I am using ros fuerte on ubuntu 12.04. I downloaded all required packages from hector repository and did a rosmake cleanly. I have a hokuyo lidar 04lx on my turtlebot1, with irobot create.

However, I do not understand how to use the hector slam on turtlebot. What parameters and launch file do I need to use to run and do mapping? Can I use the default launch files out of the box and get the it work. (so far not able to do it, I cannot see anything on the rviz)

Can some describe step by step procedure to follow and successfully implement hector slam to work, and any modification that needs to be done to the launch files. (Sorry, I am very new to ROS and have so far successfully run GMapping on turtlebot).

Thank you
