Abstract: Detecting fire and extinguishing is a hazardous job for a fire extinguisher, it often risks the life of that person. This project aims in giving a technical solution to the mentioned problem. A robot is a mechanical design that is capable of carrying out a complex series of actions automatically, especially one programmable by a computer. A fire extinguisher robot is a DTMF tone controlled robot that has a small fire extinguisher unit added on to it. This mobile robot is controlled using a mobile phone through DTMF tones for its movement and reaching the fire, the flame sensor detects the fire and gives the further signal to the extinguisher units to trigger the pump and spray the water. The whole system is programmed using an arduino UNO board (ATmega328P microcontroller) which forms the brain of the system.

Keywords: DTMF technology, DC motors, flame sensor, water pump, arduino.
