      Moveit2的官方教程里的Visualizing In RViz部分

      这一部分的最后应该可以通过点击两下RvizVisualGui里面的Next分别让Moveit执行Planning和Execut两个部分
      但是我现在只能Planning，怎么点击next都没用
      就像这样

        @1206768372 在 Moveit2教程中，无法通过点击RvizVisualGui里的next使机械臂执行规划的路径 中说：

        if (success) {
        draw_trajectory_tool_path(plan.trajectory_);
        moveit_visual_tools.trigger();
        prompt("Press 'Next' in the RvizVisualToolsGui window to execute");
        draw_title("Executing");
        moveit_visual_tools.trigger();
        move_group_interface.execute(plan);

        只有規劃成功後才能進行plan

            但是没看到这句话的打印,估计跟这个错误有关系

              最后由 1206768372 编辑

              @小鱼 问题终于解决了 Moveit2的官方教程有些问题。

              首先得先把原本默认使用的Fast DDS改成 Cyclone DDS

              sudo apt install ros-rolling-rmw-cyclonedds-cpp

              或者跟着这个

              然后重启终端

              接着再打开hello_moveit.cpp

              把这一段初始化提到新建一个Thread之前

              // Create the MoveIt MoveGroup Interface
using moveit::planning_interface::MoveGroupInterface;
auto move_group_interface = MoveGroupInterface(node, "panda_arm");

  // We spin up a SingleThreadedExecutor so MoveItVisualTools interact with ROS
  rclcpp::executors::SingleThreadedExecutor executor;
  executor.add_node(node);
  auto spinner = std::thread([&executor]() { executor.spin(); });

              接着重新编译 就可以解决了！

              GitHub上的解决办法在这
