Hi,

I am using the a pixhawk connected to the odroid for a quadcopter. I am detecting the obstacles using a LIDAR. I am attaching the lidar to a servo so that I can do a lidar sweep.I am running the pixhawk in offboard mode and trying to control the servo motor through the auxiliary ports (AUX). We found a way in this link below.

But the problem is that there is a problem in using nutshell with the pixhawk, Everytime I use the command below, I get either gibberish or a line saying that [Screen Is Terminating].

screen /dev/ttyACM0 BAUD_RATE 8N1

I have tried different baud rates like 57600 115200 921600 9600. None of them seem to work.

Kindly let me know if you a solution for this or if there is an alternative to controlling the servo using pixhawk.

Thanks, Vivek

Here I have a code for servo_controller which may help. You may add comments for further doubts. Here I've used urdf files for convience, but sdf files can also be integrated. There is also a ros package which controls the servo which will aid you further https://github.com/Gauraviitkgp/Servo...

Hey ! Just something which may help. Don't have experience with Mavros so this is not the ROS way of doing it.
