AIM OF THE PROJECTThe project aims in designing a multi-purpose security

Robot. This Robot helps in watching the premises of industries and also alerting for different industry related security risks.

The propose Robot is capable of detecting Landmines,unautorized entry.

The Robot has got the automatic night vision capability. Also, the Robot is provided with a laser gun which will be

very helpful. The controlling of Robot is done through PC wirelessly

by accepting the speech commands given by user, which makes controlling easier.

PIC is a family of Harvard architecture microcontrollers made by Microchip Technology, derived from the PIC1640 originally developed by General Instrument's Microelectronics Division. The name PIC initially referred to "Peripheral Interface Controller".

A PIC's instructions vary from about 35 instructions for the low-end PICs to over 80 instructions for the high-end PICs. The instruction set includes instructions to perform a variety of operations on registers directly, the accumulator and a literal constant or the accumulator and a register, as well as for conditional execution, and program branching.

PIC MICROCONTROLLER

Proximity/Metal detection sensor A metal detection is a device which responds to metal that

may not be readily apparent.

Metal detection sensor is digital sensor. it gives the output either 1 (if landmine detected) or 0 (if not found).

If the landmine is detected then it will alert the microcontroller, then it will perform the concerned operation.

DC MOTORS

In any electric motor, operation is based on simple electromagnetism. A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field, it will experience a force proportional to the current in the conductor, and to the strength of the external

magnetic field.

Every DC motor has six basic parts -- axle, rotor (armature), stator, commutator, field magnet's, and brushes. In most common DC motors the external magnetic field is produced by high-strength permanent magnets.

ZIGBEEZIGBEE is a wireless technology developed as an open global

standard to address the unique needs of low-cost, low-power, wireless sensor networks.

ZIGBEE is used for wireless communication that is we can send the data through air.(with out need of any physical connection between the transmitter and receiver.)

The protocol allows devices to intercommunicate and be powered by batteries that last years instead of hours.

wireless video camera Wireless Security Cameras are fast gaining popularity. They are

chosen above the common house surveillance cameras because they do away with the cluster of wires and are therefore easy to install and administer.

Wireless security cameras can be used for almost anything, from common home surveillance like keeping an eye on the nanny or adding security to the office or warehouse

Wireless video surveillance camera systems are therefore, much more opted for than wired security systems

The ROBOT can be implemented for remote surveillances of war field.

The robot can be used in military applications for safe transfer of pictures.

The robot can be used for fault detection in company premises in atomic power stations and in coal fields.

The robot can also be used for bomb detection.

Features of the project

Wireless controlling of Robot through PC using speech recognition technique.

Capable of identifying different security risks and alerting.

Shooting with the help of laser. Automatic night vision capability Live Audio and video can be seen on TV.

ADVANTAGES OF THIS PROJECTADVANTAGES OF THIS PROJECT

Wireless controlling of Robot through PC using Zigbee technology.

Capable of detecting bombs.

Capable of detecting fire.

Capable of detecting obstacles.

Shooting with the help of laser.

Alerting through buzzer alarm system.

Live Audio and video can be seen on TV.

DISADVANTAGES OF THIS PROJECTDISADVANTAGES OF THIS PROJECT If the camera fails to operate the user cannot identify his own

soldiers.

If the metal detection sensor is not in a working mode then robot can be damaged by the bombs.

If the driver mechanism fails to rotate then laser will not be operated in a accurate manner.

FUTURE SCOPE

The robot can also perform the more efficient task by using effective sensors (for metal detection, video transmission, PIR sensor for detecting live human beings).
