ABSTRACT

Secured robots are becoming more commonplace in the framework of military service, as well as other forces Military robots are already performing repetitive tasks like moving supplies and loading cargo, as well as particularly dangerous missions like evacuating casualties under fire, disabling explosive devices and collecting information in hostile environments. All experts agree that their utility will continue to expand at an increased pace.

     In today’s geopolitical climate, ensuring the protection of secure facilities or key locations against resourceful and determined intruders is of paramount importance to the defence of a national border as well as industries of national importance. The greatest threat to national security is “Terrorism” and it cannot be defeated by conventional military force alone.

EXISTING SYSTEM:

     In critical border areas such as Kashmir and Bangladesh, regular forces or even satellites cannot monitor these intruding terrorists as the area monitored is quite large and quite complex

PROPOSED SYSTEM:

     These sensors are mounted at the front of each SRV (swarm robots vehicles), enabling it to detect the distance between objects and change direction if they get too close to each another.Here to assist the army and security forces operating in these areas, smart dust like micro-sensors with wireless interfaces could be utilized to study and monitor these environments from a certain distance for military purposes.

Project description:

     The project aims to develop next generation wireless sensor networks for defense industry and homeland security applications..The smart dust wireless sensor mote detects and classifies into vehicles, individuals and groups. These motes have a variety of sensors i.e. vibration/seismic, magnetic, acoustic and thermal, a microcontroller for processing these sensor values and a radio transceiver for communication over a wireless network. The sensor readings are processed to classify detected target and the result is transferred to the central unit via wireless network using special protocol. A network of this type can be deployed within an area as large as 4,000m² in a few minutes by one or two men.The central monitoring node acts as the parent node in a peer to peer wireless network model.

     The dust motes communicate with central parent node using LR-WPAN. Microchip PIC microcontroller and MiWi P2P wireless protocol is used in all dust motes and they are typically battery powered. Microchip’s MRF24J40MA, the RF transceiver used in this implementation, is a 2.4 GHz wireless transceiver module which offers low-data rate, low-power consumption and has an integrated PCB antenna with matching circuitry.

Project Advantages:

  • Capable of detection, analyze and location of the intruder.
  • Very small in size.
  • Low-data rate, low-power consumption.
  • Highly security and safe.

Software Libraries Used:

  • PIC18F Device Driver Library.
  • Sensors: ADC device drivers.
  • IEEE 802.15.4 Wireless Protocol Stack.
  • MRF24J40MA Microchip Wireless MiWi via SPIC protocol.

     Software Tools Used:              

  • Programming Language : Embedded C
  • Development Tool :         MPLAB IDE 8.56v
  • Compiler :         C18

Embedded Protocols Used:

  • I2C – (Inter integrated circuit ) Serial communication Protocol
  • SPI – (Serial peripheral interface).

Hardware used:

  • Microcontroller : PIC 18f45j11.
  • MiWi Module :  Wireless Transceiver.
  • Digital Display : 20X4LCD.
  • PIR sensor : Motion.
  • Flame Sensor : LM 35.
  • Proximity sensor : To detect metal type martials.
  • DC Gear Motor : 12v DC (30/ 100 rpm)
  • Battery : Battery 12V ,1.2 Amps
  • I/O Expander : PCF8574AP

Swarm robotics:

     A new approach to the coordination of multirobot systems which consist of large numbers of mostly simple physical robots. It is supposed that a desired collective behavior emerges from the interactions between the robots and interactions of robots with the environment.
