作为多年的机器人爱好者，我相信你一定也有和我们一样的痛苦：

“搭建一个完整的机器人仿真环境从来不是一件容易的事”
“别人发给我的仿真文件，第一次打开，永远是报错的......“

开发一个上手就用的机器人仿真系统，是我们这个团队的一个愿望。所以，我们就开发了一个叫rabo的系统。
rabo是一个基于浏览器的机器人sim2real平台，可以理解为浏览器版本的gazebo，我们还额外做了快速部署硬件的功能。
打开浏览器，你就有了完整的机器人仿真环境和ROS2开发环境，告别虚拟机告别搭环境，直接开工～

我们准备面向轻量级开发者免费提供社区版rabo，包括上面提到的所有功能。社区版准备在8月底上线，感兴趣尝鲜的同学可以留言，我们提供测试链接～

这是一个示例场景：

Ubuntu22 ros2 humble
按照官方教程，从源码编译安装movei2后，

ros2 launch moveit2_tutorials demo.launch.py

运行信息看起来正常，rviz2能启动，只是rviz界面在屏幕外，也不知道怎么拉回屏幕中，有大佬遇到同样的问题吗，指点一下谢谢

求解，一步步跟着教程来的，为什么会出现构建失败的情况

我是ros2 humble 安装的moveit2
使用moveit_setup_assistant配置好的config文件夹，该做的设置都做了，demo.launch.py也能跑起来。
在我运行一个运动规划时报错：
[ERROR] [1755228331.551841031] [move_group_interface]: MoveGroupInterface::plan() failed or timeout reached

同时[WARN] [1755228291.666113659] [moveit_ros.robot_model_loader]: No kinematics plugins defined. Fill and load kinematics.yaml!
很奇怪，
demo.launch.py内容如下

from moveit_configs_utils import MoveItConfigsBuilder from moveit_configs_utils.launches import generate_demo_launch def generate_launch_description(): moveit_config = MoveItConfigsBuilder("zhijiao_robot", package_name="zhijiao_robot0802_moveit_config").to_moveit_configs() # print(moveit_config) return generate_demo_launch(moveit_config)

demo.launch.py运行信息：

我也怀疑过是未正确加载kinematics.yaml，于是我在demo.launch.py中加上print(moveit_config)，运行信息中打印出了moveit_config信息，其中包含
robot_description_kinematics={'robot_description_kinematics': {'manipulator': {'kinematics_solver': 'kdl_kinematics_plugin/KDLKinematicsPlugin', 'kinematics_solver_search_resolution': 0.005, 'kinematics_solver_timeout': 0.005}}},
各位大神，有没有遇到同样问题的，怎么解决

    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。
