回复: 动手学ros 10.3.2 配置使用IMU后，出错同样的问题，我用的是虚拟的imu，启用imu'数据后也报错!截图 2025-06-05 17-24-58.png cartographer_node节点直接不见了

目前可以通过Rviz2中手动标记目标点实现导航，但是我想用Nav2的API simple_commander实现导航，gotoPose和followPath方法都尝试了，分别有不同的报错：
gotoPose：开始导航后显示距离目标点的距离是0，机器人也开始转圈，转了几秒之后就显示导航失败。Rviz中的机器人模型也在一直旋转

followPath:无法生成正常的路径

位置初始化我订阅了/initialpose话题，通过rivz2的2D pose Estimation给定位置。 调用API的代码如下图：

《多协议传输控制器》使用以太网直连方式接入 ROS 系统

开始前准备：

硬件：

传输控制板*1 Type-B电源线*1 网线*1 带网口的电脑或者USB网卡*1 9~28V电源

软件：

安装Ubuntu的系统*1 安装好ROS2 Humble以上版本ROS系统 1. micro-ROS Agent 和 消息接口下载与构建

在主目录下创建，ros2_transmission_ws 目录及子目录src（其他目录也可以）

mkdir -p ~/ros2_transmission_ws/src

下载源码

cd ~/ros2_transmission_ws/src git clone http://github.fishros.org/https://github.com/fishros/micro-ROS-Agent -b humble git clone http://github.fishros.org/https://github.com/fishros/robot_interfaces git clone http://github.fishros.org/https://github.com/micro-ROS/micro_ros_msgs.git -b humble

构建工作空间

cd ~/ros2_transmission_ws/ colcon build --- Starting >>> micro_ros_agent Starting >>> robot_interfaces Finished <<< robot_interfaces [6.76s] [Processing: micro_ros_agent] --- stderr: micro_ros_agent 正克隆到 'xrceagent'... 切换到一个新分支 'ros2' HEAD 目前位于 c25243c Enable Domain Override on Reference and XML Participant (#351) CMake Warning (dev) at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message): The package name passed to `find_package_handle_standard_args` (tinyxml2) does not match the name of the calling package (TinyXML2). This can lead to problems in calling code that expects `find_package` result variables (e.g., `_FOUND`) to follow a certain pattern. Call Stack (most recent call first): cmake/modules/FindTinyXML2.cmake:40 (find_package_handle_standard_args) /opt/ros/humble/share/fastrtps/cmake/fastrtps-config.cmake:51 (find_package) CMakeLists.txt:153 (find_package) This warning is for project developers. Use -Wno-dev to suppress it. --- Finished <<< micro_ros_agent [56.9s] Summary: 2 packages finished [58.9s] 1 package had stderr output: micro_ros_agent

看到：Summary: 2 packages finished [58.9s] 就表示构建成功了，中间的警告请忽略。

2.完成硬件连接

这种连接方式的特点是，通过网线将雷达和电脑(控制卡)直连，优点是稳定。

连接方式：

电脑<----Type-B|USB线----->控制板USB口
电脑<----网线----->控制板网口
电源---->控制板电源口

3.使用配置助手修改配置

打开配置助手，扫描配置，确认如下选项的值，若不是，请手动修改。

配置项 描述 默认值 transport_mode 传输模式（例如以太网静态IP配置协议） eth_static server_ip 服务器的IP地址 192.168.168.5 eth_ip 设备的以太网IP地址 192.168.168.250 server_port 服务器的端口号 8888

传输模式我们这里采用 eth_static ，静态IP模式，并设置控制板的IP地址为 192.168.168.250 ，你也可以自己根据情况设定，但需要保证，服务IP,以太网IP在同一个子网下。

设置完成后请手动或者点击配置助手的重启设备进行重启。

4. 设置电脑IP地址

为了调试方便，我们手动来修改电脑中对应接口的网卡IP地址为配置中的server_ip，在Linux中使用 ifconfig可以临时设置对应网卡的IP地址。（注意只是临时，调试阶段建议使用，正式使用请文末方法）

使用ifconfig查看所有网卡

ifconfig --- enx4ce173422378: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::915b:c170:f24c:844c prefixlen 64 scopeid 0x20<link> ether 4c:e1:73:42:23:78 txqueuelen 1000 (以太网) RX packets 22 bytes 7392 (7.3 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 136 bytes 15185 (15.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (本地环回) RX packets 879222 bytes 758350473 (758.3 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 879222 bytes 758350473 (758.3 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

可以看到我这里有一个USB网卡：enx4ce173422378 是以太网（你的可能不是这个名字，请仔细辨别）

接着我们用ifconfig来设置IP地址，

sudo ifconfig enx4ce173422378 192.168.168.5 netmask 255.255.255.0

设置完成后再次查看这个网卡的IP地址。

ifconfig enx4ce173422378 enx4ce173422378: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.168.5 netmask 255.255.255.0 broadcast 192.168.168.255 inet6 fe80::915b:c170:f24c:844c prefixlen 64 scopeid 0x20<link> ether 4c:e1:73:42:23:78 txqueuelen 1000 (以太网) RX packets 8 bytes 2688 (2.6 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 38 bytes 6858 (6.8 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

可以看到这里的地址，inet 192.168.168.5 netmask 255.255.255.0 broadcast 192.168.168.255， 已经被成功设置了。

5.运行agent,接收消息

进入到工作空间，运行agent

cd ~/ros2_transmission_ws/ source install/setup.bash ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888 -v4 --- [1718247114.695455] info | UDPv4AgentLinux.cpp | init | running... | port: 8888 [1718247114.695599] info | Root.cpp | set_verbose_level | logger setup | verbose_level: 4 [1718247213.629429] info | Root.cpp | create_client | create | client_key: 0x17679F09, session_id: 0x81 [1718247213.629612] info | SessionManager.hpp | establish_session | session established | client_key: 0x17679F09, address: 192.168.168.250:47138 [1718247213.661143] info | ProxyClient.cpp | create_participant | participant created | client_key: 0x17679F09, participant_id: 0x000(1) [1718247213.663314] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x000(2), participant_id: 0x000(1) [1718247213.664917] info | ProxyClient.cpp | create_publisher | publisher created | client_key: 0x17679F09, publisher_id: 0x000(3), participant_id: 0x000(1) [1718247213.666583] info | ProxyClient.cpp | create_datawriter | datawriter created | client_key: 0x17679F09, datawriter_id: 0x000(5), publisher_id: 0x000(3) [1718247213.668377] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x001(2), participant_id: 0x000(1) [1718247213.669829] info | ProxyClient.cpp | create_subscriber | subscriber created | client_key: 0x17679F09, subscriber_id: 0x000(4), participant_id: 0x000(1) [1718247213.671514] info | ProxyClient.cpp | create_datareader | datareader created | client_key: 0x17679F09, datareader_id: 0x000(6), subscriber_id: 0x000(4) [1718247213.673291] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x002(2), participant_id: 0x000(1) [1718247213.674897] info | ProxyClient.cpp | create_publisher | publisher created | client_key: 0x17679F09, publisher_id: 0x001(3), participant_id: 0x000(1) [1718247213.676535] info | ProxyClient.cpp | create_datawriter | datawriter created | client_key: 0x17679F09, datawriter_id: 0x001(5), publisher_id: 0x001(3) [1718247213.678195] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x003(2), participant_id: 0x000(1) [1718247213.679745] info | ProxyClient.cpp | create_subscriber | subscriber created | client_key: 0x17679F09, subscriber_id: 0x001(4), participant_id: 0x000(1) [1718247213.681438] info | ProxyClient.cpp | create_datareader | datareader created | client_key: 0x17679F09, datareader_id: 0x001(6), subscriber_id: 0x001(4) [1718247213.683368] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x004(2), participant_id: 0x000(1) [1718247213.685201] info | ProxyClient.cpp | create_publisher | publisher created | client_key: 0x17679F09, publisher_id: 0x002(3), participant_id: 0x000(1) [1718247213.686799] info | ProxyClient.cpp | create_datawriter | datawriter created | client_key: 0x17679F09, datawriter_id: 0x002(5), publisher_id: 0x002(3) [1718247213.688641] info | ProxyClient.cpp | create_topic | topic created | client_key: 0x17679F09, topic_id: 0x005(2), participant_id: 0x000(1) [1718247213.690344] info | ProxyClient.cpp | create_subscriber | subscriber created | client_key: 0x17679F09, subscriber_id: 0x002(4), participant_id: 0x000(1) [1718247213.692013] info | ProxyClient.cpp | create_datareader | datareader created | client_key: 0x17679F09, datareader_id: 0x002(6), subscriber_id: 0x002(4)

看到上面的日志就表示连接成功了，接着就可以尝试订阅IO状态话题，打开新的终端，输入如下命令：

cd ~/ros2_transmission_ws/ source install/setup.bash ros2 topic echo /read_io --- analog: [] digital: - 1 - 1 - 1 - 1 --- analog: [] digital: - 1 - 1 - 1 - 1 --- ...

可以看到这里每帧输出了四个数据，是四个输入IO的状态，这个话题默认以10Hz进行发布，发布频率可以修改。

使用 ros2 topic list 可以查看控制器节点可以支持的话题。

话题名称 消息接口 订阅/发布 /write_485 robot_interfaces/msg/RawUInt8 订阅 /write_can robot_interfaces/msg/CanFrame 订阅 /write_io robot_interfaces/msg/WriteIO 订阅 /read_485 robot_interfaces/msg/RawUInt8 发布 /read_can robot_interfaces/msg/CanFrame 发布 /read_io robot_interfaces/msg/ReadIO 发布

关于每个话题如何使用，可以参考例程篇介绍。

6. 永久设置静态IP地址 方法1

在 Ubuntu/Debian 系统终端中输入如下命令：

编辑/etc/network/interfaces文件：

sudo nano /etc/network/interfaces

添加或修改以下内容：

auto enx4ce173422378 iface enx4ce173422378 inet static address 192.168.168.5 netmask 255.255.255.0 gateway 192.168.168.1

保存后重启即可永久设置。

方法2

查看网络接口名称：
使用以下命令查看你的网络接口名称：

ip link

找到你要设置静态 IP 的接口名称（例如 ens33 或 enx4ce173422378）。

编辑 netplan 配置文件：
打开 netplan 配置文件，例如：

sudo nano /etc/netplan/00-installer-config.yaml

在 ethernets 部分添加以下内容（根据你的实际情况进行调整）：

network: version: 2 renderer: networkd ethernets: enx4ce173422378: addresses: [192.168.168.5/24] routes: - to: 0.0.0.0/0 via: 192.168.168.1 nameservers: addresses: [8.8.8.8, 8.8.4.4]

设置文件权限

sudo chmod 600 /etc/netplan/00-installer-config.yaml

保存并应用更改：
保存文件并应用更改：

sudo netplan apply

验证设置：
使用以下命令验证你的设置：

ip addr show enx4ce173422378 ip route show

小车可以旋转和前后移动，但无法左右平移
一下是相关代码：
包括小车底盘模型，ros2 control控制以及配置文件，和启动文件
我有点担心启动文件是否正确

按照视频中的教学，解压安装，导致在烧录的时候；
打开图片文件时出错.png

具体细节和上下文：

U盘下载过两次，两次都是同样的结果，都是烧录失败；

尝试过的解决方法：

①U盘下载过两次，两次都是同样的结果，都是烧录失败；
②最后我在社区找到了3月份的一个帖子，也是同样的问题，但是我觉得用处不大，因为我想要能够安装双系统的问题没有解决；
我觉得问题的点;可能在安装包本身，①因为有其他的人有同样的结果；②在进行选择移动硬盘的时候，显示的路径感觉不太对（当时没有截），但是因为只有一个选项可以选择

    机械臂，遥操作+加力反馈，如何实现？

    遥操作：通过手柄，手机，或者任何形式的“遥控器”遥控机械臂的运动。最简单的形式就是以一个机械臂（主臂）遥控另一个机械臂（从臂）。

    力反馈：当从臂碰到障碍物时，主臂可以以力的形式感受到这个障碍物，所谓“感受”就是操作者感受到主臂的力。

    代码：https://gitee.com/qingqing-gaq/feel_force.git

    视频：https://www.bilibili.com/video/BV1KoEqzyEFR/?vd_source=36451ca805358187c4a0efa1c5694b35

    我的实现思路：
    软件：rso2
    硬件：双通道usb转can模块，六个达妙4310电机。

    六个电机，组成两个三自由度机械臂。一个can通道控制一个机械臂。

    大体逻辑：
    主臂时重力补偿模式，因为只有重力补偿才能任意拖动。主臂把实时的关节位置，发送给从臂，因此从臂必然是位置控制模式，这样才能跟踪主臂的位置。
    那么主臂如何感受从臂的力呢？这里就需要电机有力矩接口了（达妙电机的mit模式），当从臂电机受到阻力时，pid控制力就会变大，电机反馈会的力也会变大，这个变大的值就是阻力了。把这个力反馈给主臂即可。
    程序运行逻辑：
    23467808-ec76-44af-b4b5-f339ae8f85d4.png
    操作逻辑的代码：

    std::cout << "JointPositionControl::execute..............." << std::endl; //从对应的can接收线程中读取电机状态，并更新到机械臂类储存关节状态的变量（下面会用到）中 arm->update_current_joint_states();//一定要在get_current_joint_states()之前执行 arm2->update_current_joint_states();//一定要在get_current_joint_states()之前执行 //从机械臂类里返回储存关节状态的变量 const auto &curret_joint_states = arm->get_current_joint_states(); const auto &curret_joint_states2 = arm2->get_current_joint_states(); //根据当前的关节状态，计算逆动力学，进行重力补偿。 arm->computeInverseDynamics(arm->current_joint_positions, arm->current_joint_velocities, arm->current_joint_acceleration, arm->gravity_joint_tauqes); arm2->computeInverseDynamics(arm2->current_joint_positions, arm2->current_joint_velocities, arm2->current_joint_acceleration, arm2->gravity_joint_tauqes); std::vector<float> pos1(arm->getDof(), 0.0f); std::vector<float> pos2(arm->getDof(), 0.0f); std::vector<float> vel(arm->getDof(), 0.0f); std::vector<float> vel2(arm->getDof(), 0.0f); std::vector<float> tor(arm->getDof(), 0.0f); std::vector<float> tor2(arm2->getDof(), 0.0f); for (size_t i = 0; i < arm->getDof(); i++) { if(i==2) {//三号电机转向和模型相反，所以要单独加一个负号 tor[i] = -arm->gravity_joint_tauqes(i);//发送给主臂的重力补偿力矩 tor2[i] = -arm2->gravity_joint_tauqes(i);//发送给从臂的重力补偿力矩 } else { tor[i] = arm->gravity_joint_tauqes(i);//发送给主臂的重力补偿力矩 tor2[i] = arm2->gravity_joint_tauqes(i);//发送给主臂的重力补偿力矩 } //主臂的关节速度，发送给从臂 vel2[i] = 0.10 * curret_joint_states.at(i).velocity; // 系数越大手感越硬。 //主臂的关节位置，发送给从臂 pos2[i] = curret_joint_states.at(i).position; } float torque_threshold = 0.04f; // 设置阈值 //从臂受到的阻力，返回给主臂 for (size_t i = 0; i < arm->getDof(); i++) { if (std::abs(curret_joint_states2.at(i).torque) > torque_threshold) { tor[i] += -0.5 * (curret_joint_states2.at(i).torque - tor2[i]); // 如果超过阈值，按原逻辑计算 } else { tor[i] += 0.0f; // 否则赋值为 0 } } // pos2[0] = 0; tor2[0] = 0; arm->send_joint_states(pos1, vel, tor);//向主臂发送关节的状态 arm2->send_joint_states(pos2, vel2, tor2);//向从臂发送关节的状态

    其中：主臂位置发送给从臂的逻辑好理解。

    pos2[i] = curret_joint_states.at(i).position; //curret_joint_states.at(i).position：主臂的实时关节位置 //pos2[i]：发送给从臂的关节位置

    这一句是从臂的力矩反馈给主臂。有一步操作是从臂反馈的力矩减去了重力补偿力矩，这是因为，反馈的电机力矩是pid产生的。这个pid产生的控制力矩就包含重力力矩，如果把这个力也算上发送给主臂，那主臂就会变的很称，因为从臂把重力也传过来了。

    tor[i] += -0.5 * (curret_joint_states2.at(i).torque - tor2[i]); //tor[i]： 发送给主臂的关节力矩 //curret_joint_states2.at(i).torque：从臂电机反馈会来的力矩 //tor2[i]：发送给从臂的重力补偿力矩。 //-0.5：缩放系数

    这个if判断的作用是，避免从臂传来的力一直在小幅度波动，只有从臂反馈的力大于一个值，这个力才会被加载到主臂上。

    float torque_threshold = 0.04f; // 设置阈值 //从臂受到的阻力，返回给主臂 for (size_t i = 0; i < arm->getDof(); i++) { if (std::abs(curret_joint_states2.at(i).torque) > torque_threshold) { tor[i] += -0.5 * (curret_joint_states2.at(i).torque - tor2[i]); // 如果超过阈值，按原逻辑计算 } else { tor[i] += 0.0f; // 否则赋值为 0 } }

    这又是一个神奇的操作。就是让从臂有期望速度。作用就是会影响操作手感。

    vel2[i] = 0.10 * curret_joint_states.at(i).velocity; // 系数越大手感越硬。

    ok这就是整个的实现逻辑，非常简陋。

    @2475887309 感谢大佬，现在成功烧录进去了，上位机的程序也可以读到stm32发来的ros话题了。
    还有个问题想问一下就是为什么要先在上位机上打开agent再接上开发版。如果想要在任何时候打开agent都能读到话题应该怎么做？
