问题描述：

尝试使用plugin来控制场景的model来构建一个有动态障碍物场景，sdf文件如下： <?xml version="1.0" ?> <sdf version="1.7"> <world name="dynamic_world"> <physics name="1ms" type="ignored"> <max_step_size>0.001</max_step_size> <real_time_factor>1.0</real_time_factor> </physics> <!-- 插入天空环境 --> <atmosphere type="adiabatic"/> <!-- 插入一个光源 --> <light name="sun_light" type="directional"> <cast_shadows>true</cast_shadows> <pose>0 0 10 0 0 0</pose> <diffuse>1 1 1 1</diffuse> <specular>0.1 0.1 0.1 1</specular> <direction>-0.5 0.5 -1</direction> </light> <!-- 插入地面平面 --> <model name="ground_plane"> <static>true</static> <link name="link"> <collision name="collision"> <geometry> <plane> <normal>0 0 1</normal> <size>100 100</size> </plane> </geometry> </collision> <visual name="visual"> <geometry> <plane> <normal>0 0 1</normal> <size>100 100</size> </plane> </geometry> <material> <ambient>0.5 0.5 0.5 1</ambient> <diffuse>0.5 0.5 0.5 1</diffuse> </material> </visual> </link> </model> <model name="pedestrian_0"> <static>false</static> <link name="link_p0"> <pose>-4 7 0 0 0 0</pose> <inertial> <mass>55</mass> <inertia> <ixx>14.86</ixx><ixy>0</ixy><ixz>0</ixz> <iyy>16.23</iyy><iyz>0</iyz> <izz>2.36</izz> </inertia> </inertial> <collision name="box"> <pose>0 0 0.9 0 0 0</pose> <geometry> <cylinder> <radius>0.17</radius> <length>1.77</length> </cylinder> </geometry> </collision> <visual name="visual"> <geometry> <cylinder> <radius>0.17</radius> <length>1.77</length> </cylinder> </geometry> <material> <ambient>0.8 0.2 0.2 1</ambient> <diffuse>0.8 0.2 0.2 1</diffuse> </material> </visual> </link> <plugin filename="libignition-gazebo-velocity-control-system.so" name="ignition::gazebo::systems::VelocityControl"> <initial_linear>0.0 0.0 0.0</initial_linear> <initial_angular>0.0 0.0 0.0</initial_angular> <topic>/pedestrian_0/cmd_vel</topic> <link_name>link_p0</link_name> </plugin> <plugin filename="libignition-gazebo-pose-publisher-system.so" name="ignition::gazebo::systems::PosePublisher"> <publish_link_pose>true</publish_link_pose> <publish_model_pose>true</publish_model_pose> </plugin> </model> </world> </sdf> 但是ign topic -e -t /model/pedestrian_0/pose一直只输出model的初始位置，如下： ... header { stamp { sec: 20 nsec: 985000000 } data { key: "frame_id" value: "pedestrian_0" } data { key: "child_frame_id" value: "pedestrian_0::link_p0" } } name: "pedestrian_0::link_p0" position { x: -4 y: 7 } orientation { w: 1 } header { stamp { sec: 20 nsec: 986000000 } data { key: "frame_id" value: "pedestrian_0" } data { key: "child_frame_id" value: "pedestrian_0::link_p0" } } name: "pedestrian_0::link_p0" position { x: -4 y: 7 } orientation { w: 1 } header { stamp { sec: 20 nsec: 987000000 } data { key: "frame_id" value: "pedestrian_0" } data { key: "child_frame_id" value: "pedestrian_0::link_p0" } } name: "pedestrian_0::link_p0" position { x: -4 y: 7 } orientation { w: 1 } header { stamp { sec: 20 nsec: 988000000 } data { key: "frame_id" value: "pedestrian_0" } data { key: "child_frame_id" value: "pedestrian_0::link_p0" } } name: "pedestrian_0::link_p0" position { x: -4 y: 7 } orientation { w: 1 } ...

这个怎么解决呢，怎么实时输出场景中model的pose呢😧

系统是22.04

在wsl2，ubuntu22.04，ros2-humble中，输入rqt命令，提示：

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

终端运行指令

ros2 run v4l2_camera v4l2_camera_node

然后终端输出

当前用户是有操作摄像头的权限的，但依然还是出现这些问题，请各位大佬帮忙看看

a62806d8-b04f-4097-a0e2-0f028d309dc3-image.png 求大佬帮我看看，/tf发布了三个变换，/odom也正常发布了，/scan不知道什么原因没有在这里显示出来，但是使用echo可以打印发布的内容，内容频率什么的已经问过gpt了，tf树也可视化过了，都没什么问题。但是就/odom没法接收，一直报错。有试过将odom设置成base_frame，没报错了，但是/map不发布。求解😩

代码和书上的一样。

在《ROS2机器人开发 从入门到实践》中讲到了给机器人安装深度相机插件和激光雷达插件，但是在移动机器人导航时只用到了激光雷达的建图和导航，似乎深度相机并没有什么用处。在这里想要请教各位，现想要用深度相机进行移动机器人的建图和导航该如何做呢？以我学习到的知识来说似乎需要写一个配置文件，至于具体的操作并不是很清楚，请各位有这方面能力的大佬不吝赐教。

自定义通信接口例子，SystemStatus.msg 构建功能包时，命令行
colcon build --packages-select status_interfaces

为什么这里只对x方向速度做修正，不对y方向速度做修正。

为什么红色标注的地方不是减号，这里的坐标系变换的数学关系可以秒速一下吗？
