UNMANNED GUN CONTROL MECHANISM

Under the Guidence of Mr. ROHITH.S

PRESENTED BY:-

ASHISH RANJAN

OBJECTIVE Set up an automatic weaponry mechanism. To keep track of objects in a uncolored environment. Fire upon in case it detects a specific color .

FEATURES Cost effective. No complex hardware design is required. Only MATLAB coding is used.

SCOPE OF THE PROJECT It is used mainly in places like high altitude , cold regions. Mainly used in safeguarding boundaries. During the War it can be fixed in helicopters for automatic detection and firing.

DECODERHT12D Decoder is used in this project at receiver to decode the transmitted data from transmitter.

FEATURES:-

Operating voltage: 2.4v-12v.Low standby current.Capable of decoding 12bits of information.Binary address setting.Low power and High noise immunity CMOS Technology.

UNIPOLAR STEPPER MOTORStepper motor is used in this project to control the movement of LASER pointer toward the intruder.

FEATURE:-

The rotation angle of the motor is proportional to the input pulse. The motor has full torque at standstill. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3-5% of a step and this error is non-cumulative from one step to another.

CAMERACreative sync used as sensor to input the image of area under surveillance and it acts as a vision to the computer.

FEATURES:-

Sensor: VGA (640 X 480) CMOS image sensor. Video Resolution: Up to ( 800 X 600)pixels. Picture Resolution: Up to 1.3 Mega pixels. Works with native Windows drivers for instant plug & play.

SOFTWARE IMPLEMENTATION

1. MATLAB SOFTWARE :- It is a program for doing numerical computation.

2. KEIL SOFTWARE :- It provides tools for the 8051 family of Microcontrollers and it is also used to compile C code.

MATLAB CODE AND EXPECTED OUTPUT

ADVANTAGES AND DISADVANTAGES

Advantages:-

It is used at extreme conditions.Cost effective.High performance language is used.Safe and secured.

DISADVANTAGES:-

Difficulty in mounting.Special night vision cameras required in dark and bad light conditions

CONCLUSION

This project is designed to safe ground the boundaries at extreme conditions. Where human intervention is very difficult and save the precious live of our soldiers. It is used to reduce the power consumption of the microcontroller using OS concepts. The direction of the LASER is accurately pointed by alleging the camera with respect to the stepper motor. The power consumption of LASER is reduced by using relays.
