Android Controlled Fire Fighter Robot Using IoT

Abstract

The main aim of this work is to develop a manually operated camera assisted firefighting robot with the capability to extinguish fire and controlled remotely by using an Android application. In this proposed work, a robot prototype was developed with the inclusion of camera module and relevant sensors. The robot was interfaced with Blynk IoT platform, which can be used by an Android device to control the robot. The performance of the developed robot is evaluated by testing the speed, water sprayer, sensors, fire extinguishment, and operating distance. The overall robot speed is lower than expected due to the condition of the test, which is 13.118 cm per second. The effective water sprayer area is 85 cm squared, that is considered as small due to the limited aiming angle. The overall sensors accuracy while considering several distances is 77.47%, which can be improved with omni-directional sensors. The fire extinguishment test proved that the robot is suitable for extinguishing spread type of fire. The optimal operating distance of the robot from the local server is from 0 to 26 meters, considering concrete walls as obstacles. Finally, the developed system has proved that the implementation of Android device and IoT platform is doable while retaining the core features such as live camera feed, fire detection, and fire extinguishment.
