hector_mapping set-up
From the tutorial (http://www.ros.org/wiki/hector_slam/Tutorials/SettingUpForYourRobot) which launch file is to be edited?
hector_slam/hector_mapping/launch/mapping_default.launch
or other?
Also, from the tutorial the parameters are listed as value="base_frame", value="odom", etc.; but in the launch file (mapping_default.launch) the parameters are listed as value="$(arg base_frame)" and value="$(arg odom_frame)"...
Am I in the wrong file or is setting arguments and calling them vs. the examples published in the tutorial a change from ROS electric to ROS fuerte?
