Code is in Keil and PCB is in the Eagle software and pdf files. https://drive.google.com/open?id=1_kFZ5-Dxpy3w30wHz253Tpr67fvNe4pN Working: The heart of this project is Microcontroller. The project is designed to develop a fire fighting robot using GSM mobile phone technology. The robotic vehicle is loaded with water tanker and a pump which is controlled over wireless communication to throw water. An 8051 series of microcontroller is used for the desired operation. At the transmitting end using push buttons, commands are sent to the circuit to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end three motors are interfaced to the microcontroller where two of them are used for the movement of the vehicle and the remaining one to position the arm of the robot. A water tank along with water pump is mounted on the robot body and its operation is carried out from the microcontroller output through appropriate signal from the transmitting end. The whole operation is controlled by an 8051 series microcontroller. A motor driver IC is interfaced to the microcontroller through which the controller drives the motors. The project is wirelessly controlled using DTMF IC MT8870. This is a Double Tone Multiple frequency generator. Here total two mobile are used one mobile phone will always with the circuit and the other will be with user’s as shown in the block diagram above as user’s cellphone and Circuits cellphone. A special type of double tone multiple frequencies get generated when we press any key of our cell through 0-9. This frequency is taken to the circuit through headphone . we can transmit this multiple frequency from one cell to another cell wirelessly. The multiple frequency is decoded by the decoder MT 8870 IC and the decoded signal is sent to the LED display for the clear visual indication that whether the signal from behind is coming or not and then to the microcontroller for the further processing. According to the keys press microcontroller sends signal to the current driver IC l293d which in turn send the amplified signal with high current and voltage gain. We have set a sounder on the robot. It sounds when the robot detect any fire near it. The fire is detected by the fire sensor or smoke sensor. As soon as the fire sensor detect the fire it immediately sends the signal to the microcontroller and controller activate the buzzer so that the user have attention of fire in his / her house. The buzzer indication is important as most of the time when there is fire in the house we are in sleep state. Buzzer indication let us wake up and control the robot to extinguish the fire. Further the project can be enhanced by interfacing it with a wireless camera so that the person controlling it can view operation of the robot remotely on a screen or if we talk about economic solutions then person
