6 months ago Thanks for trying our work, but as mentioned in the readme, we need to use the default PX4 simulation environment to provide the required data topics for the algorithms, containing data from the depth camera, LIDAR, etc. (Of course, other simulation environments are possible, just with some modifications, which are also mentioned in the readme).
For your case, you need to additionally configure the px4 gazebo simulation environment and copy the simulation model files provided by the algorithm to your simulation environment folder (The drone model files and world files required for the px4 simulation are located in the px4_gazebo/resource).
You can refer to the px4 official tutorial for px4 simulation environment configuration, the process of encountering problems can google or bing. Some links to configure the environment are as follows：

Thank you to the author for sharing such an outstanding project. I have successfully installed all the necessary steps on Ubuntu 20.04 as instructed, and everything can be installed normally. However, when I tried to start the simulation environment according to the first step, I encountered the following error: ~/LAEA$ roslaunch px4_gazebo laea_gazebo_lidar.launch ... logging to /home/oem/.ros/log/5129359e-f4d6-11ee-9ee3-df354fbd0633/roslaunch-dell-3772081.log Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
