Development of DTMF centred remotely located fire extinguishing robot

Abstract

The hazardous situation such as conflagration makes the humans’ life most inconvenient and risky. It is an unavoidable situation and it is very difficult for humans to face such situations. But mechanical devices can handle such situations without Human intervention. Sometimes it is also difficult to reach fire place at remote location. A robot can easily handle such situations and can efficiently work in hazardous units. The robot can easily reach the places where man cannot reach. In the present paper a fire extinguisher robot is developed to detect fire and the robot smidgens water on flames. The robot is operated and controlled with mobile phone. Dual Tone Multi Frequency tones are produced to control the movement of the robot. In the present work an Arduino UNO microcontroller is interfaced with fire sensors and generates sequence of steps to control robot movements, direction, and pumping of water. The robot movement and other operations are controlled from remote location.
