Design and fabrication of mini firefighting device

Firefighting remains one of the most hazardous occupations, with personnel frequently required to navigate confined and unstable environments. In such conditions, limited maneuverability and delayed response times can result in severe injuries or fatalities. This project presents the design and development of a compact, automated firefighting device intended to address the limitations of existing market solutions, which are often oversized, irregularly shaped, and cumbersome to deploy in restricted spaces. The proposed device features a streamlined form factor optimised for navigating narrow gaps within collapsed structures. An integrated flame sensor enables autonomous water discharge, eliminating the need for manual activation and reducing critical response time. Components are selected based on cost-effectiveness, availability, and ease of maintenance to ensure practicality in large-scale deployment. The design is modelled in SolidWorks 2021 and manufactured using appropriate techniques, with emphasis on minimising weight and enhancing portability. Fabrication involves three primary mechanical processes: bending, joining, and cutting. Control is managed by an Arduino-based system, which aims to reduce operational errors under high-stress emergency conditions. The anticipated outcome is a lightweight, agile, and user-friendly firefighting device capable of operating effectively in confined environments while supporting faster, safer intervention. By combining compact mechanical design, autonomous sensing, and low-cost production, this project seeks to advance firefighting technology, improving both efficiency and safety in critical rescue operations.
