I am trying to setup PX4 SITL using ROS/Gazebo as the simulation environment. I am following the instructions given in the official PX4 documentation (https://docs.px4.io/master/en/ros/ros1.html). I had some doubts about the setup.
- What exactly does the command
make px4_sitl_default gazebodo ?
- While launching the MAVROS node to communicate with PX4 Firmware we launch the following launch file using :
roslaunch mavros px4.launch fcu_url:="udp://:email@example.com:14557". May I know what exactly is the
fcu_urland what does
udp://:firstname.lastname@example.org:1455stand for ?
I’ll be very grateful to get these answers,
