Feasibility Study and Selection of Open-Source Flight Controller for UAV Applications

Today, vertical takeoff multi-rotor drones are vital in many fields, including medical, delivery of commodities, agriculture, security, and surveillance. The drone's brain, or flight controller, handles all other drone activities in addition to stabilizing the drone. Flight controllers come in a variety of sizes and sophistications. Changes in gains or PID coefficients can be made with the help of flight controller configuration, which results in quick locked-in responses. This paper focused on the selection and evaluation of flight controllers suitable for a range of applications like delivery, photography and pesticide spraying based on their technical characteristics and sophistication.
