Design and Development of a Multifunctional Fire Fighting Robot Car With Live Streaming

Abstract

This project presents the design and implementation of a multifunctional Fire-Fighting Robot Car with live video streaming, aimed at assisting in fire detection and preliminary fire suppression in hazardous or inaccessible environments. The proposed system is built on a four-wheel robotic platform that provides stable movement and maneuverability over uneven surfaces. An ESP32CAM-CAM module is integrated to enable real-time live video streaming, allowing remote monitoring through a mobile application using an access point (AP) based communication system. This feature enhances situational awareness and enables the operator to visually assess fire conditions from a safe distance. The robot is equipped with a fire detection mechanism that triggers an automated response when fire is detected. Upon detection, a built-in speaker system generates an audible alert by playing a warning sound or message, such as “fire detected,” to notify nearby individuals. Additionally, a high-intensity flashlight is included, which can be remotely controlled to improve visibility in low-light or smoke-filled environments. For fire suppression, a pump motor is integrated to spray water or fire-retardant liquid toward the detected fire source, reducing the risk of fire spread during early stages. The system is powered by a rechargeable battery, ensuring portability and uninterrupted operation, and includes an onboard charging circuit for convenient and safe recharging. The combination of live streaming, audio alerting, remote monitoring, lighting control, and active fire-fighting capability makes the robot a compact and effective solution for emergency response support. Thus multifunctional robotic systems demonstrate a low-cost, scalable, and practical approach to enhancing fire safety and reducing human exposure to dangerous fire environments.
