1. clone https://github.com/Jaeyoung-Lim/mavros_humantracking and https://github.com/Jaeyoung-Lim/mavros_controllers in ~/catkin_mavros/src and build them in ~/catkin_mavros.
2. source below bash script in ~/px4/PX4-Autopilot

source /opt/ros/noetic/setup.bash
DONT_RUN=1 make px4_sitl_default gazebo-classic
source ~/catkin_mavros/devel/setup.bash 
source Tools/simulation/gazebo-classic/setup_gazebo.bash $(pwd) $(pwd)/build/px4_sitl_default
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$(pwd)
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$(pwd)/Tools/simulation/gazebo-classic/sitl_gazebo-classic

3. launch sample file

but spawnd drone Flying a messed up trajectory.

roslaunch humantracking_controller sitl_humantrack_circle.launch

roslaunch humantracking_controller multi_sitl_humantrack_circle.launch

Am I doing something wrong with the procedure?

Please forgive me I should avoid topics that are not related to this issue.
I had trouble controlling the gimbals of multiple drones and wanted to try this because it was introduced as a sample in this
issue [https://github.com/PX4/PX4-SITL_gazebo-classic/issues/540].
