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 gazebo
do ? - While launching the MAVROS node to communicate with PX4 Firmware we launch the following launch file using :
roslaunch mavros px4.launch fcu_url:="udp://:14550@127.0.0.1:14557"
. May I know what exactly is thefcu_url
and what doesudp://:14550@127.0.0.1:1455
stand for ?
I’ll be very grateful to get these answers,
TIA
