Hi I'm a biginner and learning about ROS with Turtlebot2.
I tried SLAM by reading tutorials, http://wiki.ros.org/turtlebot_navigation/Tutorials/indigo/Build%20a%20map%20with%20SLAM and http://wiki.ros.org/turtlebot_navigation/Tutorials/indigo/Autonomously%20navigate%20in%20a%20known%20map .
These tutorials told me how to make a map and do autonomous running with it.

When I tried tutorials, I controled Turtlebot2 by using a keyboard. It was hard.
I think that can I make a map with Turtlebot2 automatically running.
Is it difficult plobrem? Please give me reference literatures or information. Thank you.
