Hector mapping turtlebot

I am trying to use hector mapping on turtlebot in ROS hydro. I choose `hector_quadrotor_demo/launch/indoor_slam_gazebo.launch` as a base file. Then I created following launch file. When I run this launch file, It didn't output any error. When I try to add Map to rviz it gives `No transform from [map] to [base_footprint]` error. I cheated from [SettingUpForYourRobot](http://wiki.ros.org/hector_slam/Tutorials/SettingUpForYourRobot) in section **Use in place of gmapping**. What should I change to make it working ?
