This is the Landing gear automation navigation system prototype. For this project, the Raspberry Pi 4 programming board and Python programing language have been used. And parts were made in Autodesk Fusion Software 360 and printed using Ender 3 Pro 3d Printer.

​

The code will take altitude values from the Ultrasonic sensor after a specific value code will change the duty cycle with 50hz to rotate the servo motor 90-degree upward at take-off time and the same as the time of landing again at the specific altitude code will change the duty cycle with 50hz to rotate servo 90-degree downward.
