Hi if you want to have map only with laser I suggest you to use hector_slam. if you want to use hector_slam you need a launch file that you can find it in this link but if you want to use a sensor more than the laser scanner you can use http://wiki.ros.org/gmapping</a">gmapping that uses odometry.

I do the instruction in the Link and finally i can create a map but when i run slam.launch( modify of tutorial.launch) below error caused, what's a problem? [ERROR] [1390736724.097883974]: Trajectory Server: Transform from /map to scanmatcher_frame failed: Frame id /map does not exist! Frames (3): Frame /laser exists with parent /base_link. Frame /base_link exists with parent NO_PARENT.
