+## Mapping-based lidar-lidar
+
+We start with creating launch file four our vehicle like "Extrinsic Manual Calibration"
+process:
+
+```bash
+cd <YOUR-OWN-AUTOWARE-DIRECTORY>/src/autoware/calibration_tools/sensor
+cd extrinsic_calibration_manager/launch
+cd <YOUR-OWN-SENSOR-KIT-NAME> # i.e. for our guide, it will ve cd tutorial_vehicle_sensor_kit
+touch mapping_based.launch.xml mapping_based_sensor_kit.launch.xml
+```
+
+The created `mapping_based.launch.xml` and `mapping_based_sensor_kit.launch.xml` are version of sample sensor kit
+[aip_x1](https://github.com/tier4/CalibrationTools/tree/tier4/universe/sensor/extrinsic_calibration_manager/launch/aip_x1) provided from Tier IV.
+
+Then we will continue with adding vehicle_id and sensor model names to the `mapping_based.launch.xml`.
+(Optionally, values are not important. These parameters Overrode from launch argument)
+
+```diff
++ <?xml version="1.0" encoding="UTF-8"?>
++ <launch>
++   <arg name="vehicle_id" default="tutorial_vehicle"/> <!-- You can update with your own vehicle_id -->
++
++   <let name="sensor_model" value="tutorial_vehicle_sensor_kit"/> <!-- You can update with your own sensor_kit -->
+```
+
+After that, we will launch our sensor_kit for mapping-based lidar-lidar calibration,
+so we must add these lines on manual.launch.xml:
+
+```diff
++   <group>
++     <push-ros-namespace namespace="sensor_kit"/>
++     <include file="$(find-pkg-share extrinsic_calibration_manager)/launch/$(var sensor_model)/mapping_based_sensor_kit.launch.xml">
++       <arg name="vehicle_id" value="$(var vehicle_id)"/>
++     </include>
++   </group>
++
++ </launch>
+```
+
+The final version of the file (mapping_based.launch.xml) for tutorial_vehicle should be like this:
+
+??? note "Sample manual.launch.xml file for tutorial vehicle"
+
+    ```xml
+    <?xml version="1.0" encoding="UTF-8"?>

+    ```
+
+After the completing of mapping_based.launch.xml file,
+we will be ready to implement mapping_based_sensor_kit.launch.xml for the own sensor model:
+
+Optionally,
+you can modify sensor_kit and vehicle_id as `mapping_based.launch.xml`over this xml snippet:
+(You can change rviz_profile path after the saving rviz config as video
+which included at the end of the page)

++   <arg name="dst_yaml" default="$(env HOME)/sensor_kit_calibration.yaml"/>
+```
+
+We will not fill anything on camera parameters for calibrator
+because we will pair lidar-lidar for the calibration process:
+
+```diff

++   <let name="calibration_camera_frames" value="['']"/>

++   <let name="calibration_camera_info_topics" value="['']"/>
++   <let name="calibration_image_topics" value="['']"/>
+```
+
+We will add sensor kit frames for each lidar (except mapping lidar),
+we have one lidar for pairing to the main lidar sensor for tutorial vehicle, so it should be like:
+
+```diff
++   <let name="lidar_calibration_sensor_kit_frames" value="[sensor_kit_base_link]"/>
+```
+
+??? note "i.e., If you have three lidars (one main for mapping, two others)"

+    +  sensor_kit_base_link,
+    +  sensor_kit_base_link,
+    +  sensor_kit_base_link]"/>
+    ```
+
+We will add lidar_calibration_service_names,
+calibration_lidar_base_frames and calibration_lidar_frames for calibrator.
+At the tutorial_vehicle it should be like this snippet:
