This document summarizes research on autonomous drone delivery systems. It discusses using drones to efficiently deliver packages to multiple customers in a specified area. The drone is controlled using an electronic speed control system and GPS to navigate. One-time passwords are used for security to release packages only when the correct code is entered. The document reviews several related works on drone delivery systems and their applications, such as delivering medical supplies or improving delivery efficiency. It also discusses challenges like collision avoidance and improving drone capacity and battery life. The goal is to design a drone system that can autonomously deliver packages to multiple destinations in an efficient and secure manner.
