Hi I am trying to simulate this problem https://www.mathworks.com/matlabcentral/fileexchange/64381-matlab-and-simulink-robotics-arena-simulating-quadcopter-missions I have tried virtual box then VMware and after that I have download the files from this link https://www.mathworks.com/support/product/robotics/ros2-vm-installation-instructions-v5.html now the problem I am facing in all these cases is same when I run my simulation in gazebo I am facing errors in importing drone into the world loaded in my scenario. I have already connected simulink with ROS and works fine but my errors come in linux terminal.
Note: I have already followed steps according to documentation provided and tried videos too available on youtube and matlab platform. I have tried diffrent versions of ROS including latest version also ( ROS Noetic Humble Gazebo 11 and ROS Melodic Dashing Gazebov9 ) in a hope maybe old version might help me out in this problem but the error is consistent no matter what I try.
The Error I am facing are of the sort:
qws.urdf file is empty.
