雷达自带imu，机器人自身也有配imu，当前雷达是倾斜放置的，为了有一定高度同时探测地面低矮的障碍物，尝试了一些配置，有以下问题
1：如果tracking_frame配置为base_link，会报错，要求imu的frame id和base_link不能离太远，3d建图配置里没找到哪里可以禁用imu
2：如果tracking_frame配置为imu的frame id，则rviz中map会倾斜，导致地图都是灰色或黑色

两个imu都没有和base_link重合

请教大家个问题，在ros2的导航配置文件中，如何对规划好的全局路径进行平滑优化呢？如何在BT行为树中添加smoother_path节点？

就是我用 nc -l 8889 小车不会显示 hello fishros 然后我看雷达板上 的ip 也没了 #

应该是gpu方面gazebo和wsl2有冲突，实测把gazebo换成cpu渲染可以正常运行，但一运行cpu占用就90%，电脑风扇呼呼响，不是个办法，想问下有大佬知道怎么办吗

Q

使用鱼哥第七章的fishbot_navigation2功能包想做实体小车导航。问题是2D pose estimate后全局代价地图和局部代价地图始终不显示，请鱼哥和各位大佬看看我朝哪个方向排查：

详细描述如下：
1.版本：ROS2 jazzy ubuntu24.04 树莓派5。激光雷达是实体单线雷达 自己搓的麦轮小车，能发布里程计（自己测试还挺准的）
2.使用里程计小车能找到自己的位置，配合雷达能完成家里客厅的简单建图
3.nav2_params.yaml 和 navigation2.launch.py（这个launch里调用了nav2_bringup，传参是map_yaml_path，use_sim_time，和yaml文件路径）是在鱼哥的基础上改的，主要修改的1）use_sim_time: False 2）没有URDF，所以发布了一个 1hz的base_footprint->base_link->laser的TF 3）其他小的参数改动
4.运行navigation2.launch.py后，查看TF都正常，2Dpose estimate后能看到周围有粒子（看样子负责定位的自适应蒙特卡洛粒子滤波起作用了），但是代价地图（全局 局部）都不显示 代价地图模块说no map received
5.显然在代价地图说收不到map的情况下点NAV2 GOAL也是无效的 terminal说 没有设置起始位置（但是其实我设置了）

6 补充：我在目前的基础上丧心病狂的再运行一下ros2 launch nav2_bringup navigation_launch.py 代价地图就有了（代价有点大 我家客厅有点小😕 ），但是NAV2 GOAL还是失败

请各位大佬指点一二，帮我看看我的问题可能在哪：

**问题1 我没有代价地图的问题可能在哪？
初始位置没设置对？（AMCL模块正常，TF显示map->odom）
代价地图的YAML没配置对？（我跑鱼哥的yaml仿真能跑，仅仅改了footprint坐标系和仿真时间）
为什么我运行ros2 launch nav2_bringup navigation_launch.py 能出代价地图？

问题2 我运行ros2 launch nav2_bringup navigation_launch.py 显然是不应该有的做法，让节点重复发布了。这时候不能导航仅仅是因为节点重复发布的原因吗？还是我还有一些别的没做对？**

Screenshot 2025-06-29 121845.png
这是点2d pose estimate后的结果
Screenshot 2025-06-29 134036.png
这是此时的TF

这是此时的节点
状态反馈qt.png
这是小车反馈信息 里程计发布应该都正常（这个图是我后截取的，用遥控器控制小车 确认小车发布的里程计有效）
问题描述.png
这个是再没有代价地图的情况下强行点NAV2GOAL的结果
Screenshot 2025-06-29 143155.png
这个是运行一遍ros2 launch nav2_bringup navigation_launch.py 后的结果，注意此时节点几乎都存在两个同名节点，不知道不能导航是否和同名节点有关，但是起码运行这个显示代价地图了

我尝试使用robot_localization库去融合odom和imu的数据，来减少误差，但是这个方法只能用在一个机器人上，多个机器人的时候，分配了命名空间，robot_localization会直接不订阅任何odom和imu数据，不工作了，这种情况有什么办法解决

听小鱼的视频教程是说要配置dds 外加代码上稍微修改。
而网上其他的一些说法是，ros2 默认就支持了共享内存的方式，而且是根据消息的大小来自行决定的。

    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。
