ANDROID CONTROLLED FIRE FIGHTER ROBOT
Fire occurrences are growing more common these days, and it may be tough for firemen to save human lives in some scenarios when they are called to the scene. In the case of an unintended fire, it is not possible for a person to continuously monitor the circumstances in the vicinity. As seen in the figure, firefighting robots are sent in such instances to put out fires. The robot will scan the area for signs of fire from a distance. They are particularly useful in enterprises where there is a significant risk of an inadvertent fire happening. It is possible for the proposed vehicle to detect the presence of a fire and to extinguish it on its own, thanks to the employment of gas sensors and temperature sensors. It is fitted with a gear and a motor driver, which are used to control the movement of the robot. In this case, a relay circuit is in charge of controlling the pump, and when the circuit senses a fire, it communicates with the microcontroller (Arduino) over a Bluetooth module. With a water jet spray, the proposed robot is capable of executing the function of sprinkling water, as seen in the video. It is possible to spin the sprinkler so that it points in the appropriate direction. It is necessary to consider the chance that the vehicle would face obstacles while turning towards the source of the fire, and the vehicle is equipped with obstacle-avoiding capabilities. When it comes to Arduino functioning on Android, it will make use of a graphical user interface (GUI). It can detect impediments up to a distance of 80 yards away with the aid of ultrasonic sensors. Bluetooth will be used to communicate between the mobile phone and the robot, and the mobile phone will be equipped with a graphical user interface (GUI) that will allow the user to control the movement of the robot. A mobile device connecting to Bluetooth will first configure the module name and wide rate before connecting to Bluetooth.
