@ppoirier actually i dont want the rc to be used for the obstacle avoidance setup i only need to perform obstacle avoidance with my raspberrypi3 with ultrasonic sensor or lidar

if the above not posibble please guide me to make obstacle avoiance using raspberry pi 3 and pixhawk3 and also TFmini/ultrasonic sensor in autonomous drone delivery project for my college

Ultrasound is outdated and has too many false positives. Do like Patrick told you and get some infrared, laser or stereo camera sensors.
