This document describes an unmanned gun control mechanism that uses computer vision and automation to detect targets and fire a weapon. It uses a camera to detect objects in an uncolored environment and fire at a specific detected color. The mechanism uses inexpensive hardware like a microcontroller, RF transmitter/receiver, encoder/decoder, stepper motor, laser pointer, relay switch and camera. It is intended to safeguard boundaries in places like high altitude and cold regions, and could be mounted on helicopters. Diagrams show the components and their connections. Advantages are low cost, ability to operate in extreme conditions, and use of high-performance MATLAB coding. Disadvantages include difficulty in mounting and need for special cameras in low light.

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

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

7. TLP434A is used in this project to transmit the encoded data to
enable or disable the Gun.
FEATURES:-
 Frequency range : 433.92 MHz.
 Modulate Mode : ASK
 Data rate : 8Kbps
Supply voltage : 5v

8. HT12E encoder is used in this project to Encode the password
entered to control the automatic Weaponry Mechanism.
FEATURES:-
 Operating voltage: 2.4v-12v.
 Low standby current : 0.1A (typ.) at VDD=5v.
 Low power and High noise immunity CMOS Technology

9. RLP434A receiver is used in this project to receive the transmitted
data and it is sent to decoder.
FEATURES :-
 Frequency range : 433.92 MHz.
 Modulate Mode : ASK
 Data rate : 4800bps
 Sensitivity : -106 dBm
 Supply voltage : 5v

10. HT12D 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.

11. Stepper 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.

12. Creative 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.

8051 MICROCONTROLLER

14. Features of 8051 Microcontroller
Speed up to 33 MHz
RAM expandable externally to 64 k bytes
4 level priority interrupt
6 interrupt sources
Four 8-bit I/O ports
Full-duplex enhanced UART
Framing error detection
Automatic address recognition
Power control mode
Clock can be stopped and resumed
3 16-bit timers

15. 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.

17. 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

18. 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.
