I am trying to do a navigation stack as the first step is to create the robot_confi.launch file but the problems is I am not able to tell what are these nodes

<launch>

   <node pkg="sensor_node_pkg" type="sensor_node_type" name="sensor_node_name" output="screen">
    <param name="sensor_param" value="param_value" />
 </node>
 <node pkg="odom_node_pkg" type="odom_node_type" name="odom_node" output="screen">
    <param name="odom_param" value="param_value" />
 </node>
 <node pkg="transform_configuration_pkg" type="transform_configuration_type" name="transform_configuration_name" output="screen">
    <param name="transform_configuration_param" value="param_value" />
 </node>

</launch>

i don't know what is sensor_node_pgk, odom_pkg or tf_config

i am using head_hokuyo_sensor i have seen other questions but I got more confused.
