I have one project which wants me to move the servo by using MAVROS. The servo must be connected to pixhawk. Now I connect the servo to the pixhawk but I am not sure how to move the servo in any degrees. Please kindly teach me how to do it. I am still new to odroid and pixhawk.

I ran roslaunch mavros px4.launch, then rostopic pub -1 /mavros/rc/override mavros/OverrideRCIn '[1500, 1500, 1500, 1500, 1325, 1560, 2000, 1500]'. It showed nothing. From other website, they mentioned to set the SYSID_MYGCS to 1. I followed what they mentioned but it is still the same.
