Autonoumous Drone for Crowd Cooling via Water Mist

Project Type: Self-Initiated

Project Description

During the summer in Saudi Arabia, outdoor temperatures can exceed 45 degrees Celsius, creating hazardous heat stress conditions during major public events. This report presents the final design of an autonomous misting drone that delivers targeted evaporative cooling within a predefined restricted operating area, supported by continuous monitoring and operator override for safe operation near crowds. The final architecture integrates a UAV platform, a misting and water-delivering subsystem, docking, and mission-level control logic governing the operating, recovery, and safe-mode behaviours. The design aims to meet requirements such as ≤3 seconds decision latency, centimetre-level docking alignment, reliable supervision and telemetry, and repeatable deployment cycles. Final design analyses and performance results are presented to demonstrate compliance with key specifications. To ensure the design meets the requirements, the system is to be validated and tested through subsystem bench tests, end-to-end integration tests, and controlled flight demonstrations within a restricted operating area.
