In this paper, design and development of a multiple sensors based fire extinguisher robots is proposed and implementation is demonstrated with a brief discussion of construction and operation. The developed fire extinguisher robot can be operated in multiple modes using the DTMF and Bluetooth remote control as well as GSM and GPS technology. Basically, three different sensors of flame sensor, temperature sensor, and smoke sensor have been used to ensure proper detection of fire. The robot can be controlled using both DTMF remote control and Android smartphone and can be operated in three different modes. The first mode allows full autonomous operation of the robot which can be activated by the user or by the robot itself based on the situation. The second mode is a line following mode where robot follows a black drawn line to detect fire and the third mode is complete manual operation using remote control.
