Cosmic: A Modular Autonomous Drone Delivery System

Introducing "Cosmic," an innovative modular drone delivery platform designed to autonomously transport payloads in environments where traditional logistics falter, such as disaster- stricken areas and rural locations. At its core lies the Cosmo v1 embedded flight controller based on the STM32H7 microcontroller, which handles low-level sensor integration, motor control, and stabilization. Accompanying it is a Raspberry Pi Compute Module 5 (CM5), enabling high-level autonomy, mission logic, and edge processing. With a dual-processor architecture, Cosmic bridges the gap between reliable embedded control and adaptable decisionmaking, allowing autonomous aerial logistics even under infrastructure constraints. This paper details the system's architecture, hardware design, software implementation, comparative evaluation, and future development roadmap
