Introduction:
The face of war is changing, and it may no longer be a human one. Developing new technology has always been a cornerstone of a successful military force, but now those technologies are steadily moving human soldiers from combat to management positions. Virtually every major military power is working on robotic weapons. In short, we’re outsourcing more and more of war into the hands of robots and computers. Even the conventional foot soldier has robotic and biological augmentation in his/her future. Today, Singularity Hub is taking a wide-angle look at these changes and how they will change the nature of war and our world.
Military robots are autonomous robots or remote-controlled devices designed for military applications. Such systems are currently being researched by several militaries. The objective of this Robot is to minimize human casualties in terrorist attacks such as 26/11. The combat robot has been designed to tackle such cruel terror attacks. This robot is radio-operated, self-powered, and has all the controls like a normal car. This robot can be used in star hotels, shopping malls, jewelry showrooms, etc where there can be threats from intruders or terrorists. Since human life is always precious, these robots are the replacement for fighters against terrorists in war areas.
Block Diagram Explanation:
Power supply unit
This section needs two voltages viz., +12 V & +5 V, as working voltages. Hence specially designed power supply is constructed to get regulated power supplies.
Switches:
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. A switch may be directly manipulated by a human as a control signal to a system. Automatically operated switches can be used to control the motions of machines.
ARM processor
ARM is a computer processor-based RISC architecture. A RISC-based computer design approach means ARM processors require significantly fewer transistors than typical processors in average computers. This approach reduces costs, heat, and power use. The low power consumption of ARM processors has made them very popular:
The ARM architecture (32-bit) is the most widely used in mobile devices, and the most popular 32-bit one in embedded systems.
Zigbee Technology
ZigBee is a specification for a suite of high-level communication protocols used to create personal area networks built from small, low-power digital radios. ZigBee is based on an IEEE 802.15 standard. Though low-powered, ZigBee devices can transmit data over long distances by passing data through intermediate devices to reach more distant ones, creating a mesh network.
Buffers
Buffers do not affect the logical state of a digital signal (i.e. a logic 1 input results in a logic 1 output whereas logic 0 input results in a logic 0 output). Buffers are normally used to provide extra current drive at the output but can also be used to regularize the logic present at an interface
Drivers
This section is used to drive the relay where the output is the complement of input which is applied to the drive but the current will be amplified
Relays
It is an electromagnetic device that is used to drive the load connected across the relay and the o/p of the relay can be connected to the controller or load for further processing.
Robot:
A robot is usually an electro-mechanical machine that can perform tasks automatically. Robots can be autonomous, semi-autonomous, or remotely controlled. Robots have evolved so much and are capable of mimicking humans that they seem to have a mind of their own.
- An automatic industrial machine replaces humans in hazardous work.
- An automatic mobile sweeper machine at modern home.
- An automatic toy car for a child to play with.
- A machine removing mines in a war field all by itself and many more…
Methodology:
This project is developed for the War Field to minimize human casualties in terrorist attacks. The main modules in this project are Key inputs, ARM controller unit, LCD, Zigbee, and Robot.
The transmitter will be there with military force and the receiver will be there in the Robot. The transmitter module has Key inputs, ARM controller, and Zigbee as a communication media. The receiver has Zigbee, ARM controller, and Robot. If an Operator Presses a Switch to make the Robot move, that information will be given to the ARM controller, then the ARM controller analyses the signal and sends information to the receiver which is present in the Robot via Zigbee. At the receiver, the Zigbee receives a signal which was transmitted from the transmitter and sends that to the ARM controller. After receiving the signal the ARM controller will activate the Robot to move in a proper direction based on the key pressed like the Robot will move Front, Back, Forward, and Backward.
