I followed the instructions fromhttps://dev.px4.io/en/simulation/ros_interface.html and run these commands:
make posix_sitl_default gazebo
source ~/catkin_ws/devel/setup.bash // (optional)
source Tools/setup_gazebo.bash $(pwd) $(pwd)/build_posix_sitl_default
roslaunch px4 posix_sitl.launch
I want to know how I can add noise to sensors and how obtain data from sensors. Besides, does it use only IMU sensor? Are there not other sensors (eg.GPS/mag/lidar) in sitl?
Thank you very much!
