13.APP mapping navigation

APP mapping navigation

1. Content Description

This course explains how to use the ROS Robot app to control a robot for mapping and navigation.

This section requires entering commands in the terminal. The appropriate terminal depends on your motherboard type. This lesson uses the Raspberry Pi 5 as an example. For Raspberry Pi and Jetson Nano boards, you need to open a terminal on the host computer and enter the command to enter the Docker container. Once inside the Docker container, enter the commands mentioned in this lesson in the terminal. For instructions on entering the Docker container from the host computer, refer to [01. Robot Configuration and Operation Guide] -- [5.Enter Docker (For JETSON Nano and RPi 5)].

For Orin and RDK boards, simply open the terminal and enter the commands mentioned in this lesson.

1.1. Preparation

You must first download the ROS Rotbot app on your phone. Android/iOS phone users, please scan the QR code to download the remote control software. iOS users can also search and download the ROSRobot map navigation app from the App Store.

image-20250702142850792

The robot and phone must be on the same local area network, which can be achieved by connecting to the same Wi-Fi network.

2. App Map Creation

2.1. Program Startup

For PI5/JETSON NANO controllers, you need to enter a Docker container first; for RDK X5 and Orin boards, this is not required.

Entering a Docker container (see the Docker course for steps: 4. Docker Startup Script).

All commands below must be executed within the same Docker container (see the Docker course for steps: 3. Docker Commit and Multi-Terminal Entry).

Enter the following command on the Car terminal to start the Car app map creation.

#Start the camera
#nuwa
ros2 launch yahboomcar_depth camera_app.launch.py
#usb
ros2 launch usb_cam camera.launch.py

image-20250813194939451

xxxxxxxxxx
#Choose one of the two mapping algorithms
ros2 launch yahboomcar_nav map_gmapping_app_launch.xml
ros2 launch yahboomcar_nav map_cartographer_app_launch.xml

image-20250813195002105

The mobile app displays the following image. Enter the car's IP address, using [zh] for Chinese and [en] for English. Select ROS2. In the Video Target area below, select /camera/rgb/image_raw/compressed. Finally, click [Connect].

image-20250813195203593

After successfully connecting, the following display appears:

image-20250813195 223841

Use the wheel to slowly move the car around the area you want to map. Then click Save Map, enter a map name, and click Submit to save the map.

image-20250813195455386

The map is saved in:

xxxxxxxxxx
~/yahboomcar_ros2_ws/yahboomcar_ws/src/yahboomcar_nav/maps

image-20250813195543903

2.2. Launch Command Analysis

Code Path:

xxxxxxxxxx
~/yahboomcar_ros2_ws/yahboomcar_ws/src/yahboomcar_nav/launch/map_gmapping_app_launch.xml

Using the map_gmapping_app_launch.xml file as an example, we will explain which launch files are launched. The map_gmapping_app_launch.xml file is as follows:

xxxxxxxxxx
<launch>
    <arg name="use_rviz" default="false" />
    <include file="$(find-pkg-share rosbridge_server)/launch/rosbridge_websocket_launch.xml"/>
    <node name="laserscan_to_point_publisher" pkg="laserscan_to_point_publisher" exec="laserscan_to_point_publish"/>
    <include file="$(find-pkg-share yahboomcar_nav)/launch/map_gmapping_launch.py">
        <arg name="use_rviz" value="$(var use_rviz)"/>
    </include>
    <include file="$(find-pkg-share robot_pose_publisher_ros2)/launch/robot_pose_publisher_launch.py"/>
    <include file="$(find-pkg-share yahboomcar_app_save_map)/yahboom_app_save_map.launch.py"/>
</launch>

rosbridge_websocket_launch.xml: Launches the rosbridge WebSocket server for ROS (Robot Operating System)

laserscan_to_point_publisher: Publishes radar point cloud data to the app

map_gmapping_launch: Gmapping mapping-related nodes

robot_pose_publisher_launch.py: Publishes vehicle position information

yahboom_app_save_map.launch.py: Saves the map node

3. App Navigation

3.1. Program Startup

Enter the following command on the car terminal to start the car chassis and radar.

xxxxxxxxxx
ros2 launch yahboomcar_nav laser_bringup_launch.py

image-20250813200354626

Enter the following command on the car terminal to start the camera.

xxxxxxxxxx
#Start the camera
#nuwa
ros2 launch yahboomcar_depth camera_app.launch.py
#usb
ros2 launch usb_cam camera.launch.py

image-20250813200416155

Enter the following command on the car terminal to launch the app navigation.

If you want to use fast relocalization navigation, you must first follow the tutorials [6. LiDAR - 7. Cartographer Mapping] to save a map in pbstream format and a map in yaml format.

​x
# Navigation: Choose one of the two options
#1. Normal positioning and navigation
ros2 launch yahboomcar_nav navigation_teb_app_launch.xml
​
#2. Fast relocalization and navigation
#2.1 Positioning
ros2 launch yahboomcar_nav localization_imu_odom.launch.py ••use_rviz:=false load_state_filename:=/root/yahboomcar_ros2_ws/yahboomcar_ws/src/yahboomcar_nav/maps/yahboomcar.pbstream
#2.2Navigation
ros2 launch yahboomcar_nav navigation_cartodwb_app_launch.xml maps:=/root/yahboomcar_ros2_ws/yahboomcar_ws/src/yahboomcar_nav/maps/yahboomcar.yaml

Take standard positioning navigation as an example.

image-20250813200727226

The mobile app will display the following image. Enter the car's IP address, using [zh] for Chinese and [en] for English. Select ROS2 and select /camera/rgb in the VideoTpoic field at the bottom. Finally, click [Connect].

image-20250813200744781

After successfully connecting, select the navigation interface, as shown below.

image-20250813200855868

Then, based on the actual position of the robot, click [Set Initialization Point] to set an initial target point for the robot. If the radar scan area roughly overlaps with the actual obstacle, the position is accurate. As shown in the image below,

image-20250813200921679

Then, click [Set Navigation Point] and give the car a destination. The car will then map a route and follow it to the destination. As shown in the image below,

image-20250813200952887

3.2. Instruction Analysis

Code Path:

xxxxxxxxxx
~/yahboomcar_ros2_ws/yahboomcar_ws/src/yahboomcar_nav/launch/navigation_teb_app_launch.xml

Using the navigation_teb_app_launch.xml file as an example, we will explain which launch files are launched. The navigation_teb_app_launch.xml file is as follows:

xxxxxxxxxx
<launch>
    <include file="$(find-pkg-share rosbridge_server)/launch/rosbridge_websocket_launch.xml"/>
    <node name="laserscan_to_point_publisher" pkg="laserscan_to_point_publisher" exec="laserscan_to_point_publish"/>
    <include file="$(find-pkg-share yahboomcar_nav)/launch/navigation_teb_launch.py"/>
    <include file="$(find-pkg-share robot_pose_publisher_ros2)/launch/robot_pose_publisher_launch.py"/>
</launch>

rosbridge_websocket_launch.xml: Launches the rosbridge WebSocket server for ROS (Robot Operating System)

laserscan_to_point_publisher: Publishes radar point cloud data to the app

robot_pose_publisher_launch.py: Publishes vehicle position information

app_send_goal: Publishes navigation target topic to the app
