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.

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.
