This below picture is my ubuntu...
I command "roslaunch px4 multi_uav_mavros_sitl.launch" on my terminal.
After that, Gazebo is popped up and I can show 3drones model.
But, I have only one terminal that is just showed "pxh>".
My question is this. Why can I see just one terminal? In my think, this one terminal has 3 simulators.
How to command each drone?
