2d pose estimation in navigation with amcl

edit

Hi! I launch these files:

$ roscore
$ roslaunch frontier_exploration robot.launch
$ roslaunch modeling display.launch model:="modeling/urdf/myrobot.urdf"
$ roslaunch frontier_exploration move_base_staticmap.launch
$ roslaunch frontier_exploration global_map.launch

in robot.launch I have the commands to start the lidar and tf transformations (scanmatcher -> base_link -> neato_laser); in move_base_staticmap.launch I have this:

<launch>
<!-- Run the map server -->
<node name="map_server" pkg="map_server" type="map_server" args="$(find robot_setup_tf)/mymaps/map.yaml" output="screen"/>
<include file="$(find frontier_exploration)/launch/amcl_diff.launch">
</include>

<node pkg="move_base" type="move_base" respawn="false" name="move_base" output="screen">
<rosparam file="$(find frontier_exploration)/launch/costmap_common_params.yaml" command="load" ns="global_costmap" />
<rosparam file="$(find frontier_exploration)/launch/costmap_common_params.yaml" command="load" ns="local_costmap" />
<rosparam file="$(find frontier_exploration)/launch/local_costmap_params.yaml" command="load" />
<rosparam file="$(find frontier_exploration)/launch/global_costmap_params.yaml" command="load" />
<rosparam file="$(find frontier_exploration)/launch/base_local_planner_params.yaml" command="load" />
</node>

</launch>

Is it normal that I have to give the 2d pose estimate in rviz and it is not automatically done by amcl? Because if I move the laser, the points move but the robot model remains stationary in the map? Can I use hector_slam instead of amcl_diff.launch? If I can do, what I have to replace this file? Please if you have at least one answer to all these questions, you give me a big help! Thank you! :)
