Can you use PX4+Gazebo for simulation? By clicking on the 2D Nav Goal drone, it will drift and crash within two to three seconds of starting flight

请问有用PX4+Gazebo做fuel的仿真的吗？控制器用的是mavros_controller，在rviz中给出开始命令之后，无人机的运动很不稳定，随后即会撞墙坠毁。控制器也试过浙大高飞老师团队的px4ctrl，效果跟mavros_controller是一样的，开始两三秒就会坠毁。同时在仿真里使用的是d435i相机，fuel订阅了相机的话题，但是好像没有建图，订阅/sdf_map/occupancy_local_inflate话题输出内容为空。系统环境是Ubuntu20.04+ROS noetic。 May I ask if PX4+Gazebo is useful for fuel simulation? The controller uses Mavros_ Controller, after giving the start command in rviz, the motion of the drone is...

In rviz, it appears that frontier: Points should not be empty for specified marker type

In gazebo, the drone took off and landed repeatedly, ultimately crashing

I am using mavros_ When the controller controls the simulation of a drone, the drone takes off and lands repeatedly, ultimately crashing. I am using Ubuntu20.04.

仿真时出现process has died的错误

我在Ubuntu20.04上进行ego-planner的仿真，使用ego-planner和ego-planner-swarm都会报以下错误，请问有建议的解决方案吗？ > [drone_0_ego_planner_node-1] process has died [pid 167480, exit code -11, cmd /home/hq/ego-planner-swarm/devel/lib/ego_planner/ego_planner_node ~odom_world:=/mavros/local_position/odom ~planning/bspline:=/drone_0_planning/bspline ~planning/data_display:=/drone_0_planning/data_display ~planning/broadcast_bspline_from_planner:=/broadcast_bspline ~planning/broadcast_bspline_to_planner:=/broadcast_bspline ~grid_map/odom:=/mavros/local_position/odom ~grid_map/cloud:=/drone_0_pcl_render_node/cloud ~grid_map/pose:=/drone_0_pcl_render_node/camera_pose ~grid_map/depth:=/iris/realsense/depth_camera/depth/image_raw __name:=drone_0_ego_planner_node __log:=/home/hq/.ros/log/66fa4124-cf9d-11ed-9cc2-73ade9189e42/drone_0_ego_planner_node-1.log]. > log file: /home/hq/.ros/log/66fa4124-cf9d-11ed-9cc2-73ade9189e42/drone_0_ego_planner_node-1*.log >

你好，请问有关于px4ctrl的参考文献吗？想学习一下它的理论知识

想请问一下px4ctrl参考了那些文献？谢谢！
