Automatic Missile Defence System destroys aerial targets like aircraft, high-altitude ballistic missiles, and low-altitude cruise missiles.
Missile defense systems are really important for a nation like India which is surrounded by hostile neighbors.
A Surface to Air missile is a very high speed ( 2-4 times the speed of sound) missile that is used to engage aircraft and cruise missiles. It has excellent acceleration and a small warhead. It is usually guided by radar or Infrared.
Some of these missiles like RBS 70, Shtil, SM-2 can be used against surface targets as well. But They won’t be very effective as their warhead is designed to destroy a delicate target like an airplane and not structures like buildings or armored vehicles like tanks.
Step 1: Video Demonstration
Step 2: Things Needed
Step 3: Arduino
Arduino is an open-source electronics platform based on easy-to-use hardware and software.
It has different input /output pins of the microcontroller chip into digital input/output pins and analog input pins. Now, this board can be programmed using an awesome Arduino IDE (free to download).
Arduino comes in different shapes and sizes. some of the well-known Arduino’s are…
1. Arduino UNO
3.Arduino Pro mini
Arduino is a great tool for developing interactive objects, taking inputs from a variety of switches or sensors, and controlling a lot of lights, motors, and other outputs like a buzzer. Arduino projects can be stand-alone or they can be connected to a computer using USB.
There are a variety of projects which can be made using Arduino, like remote control car, automation, and other embedded systems and IoT (Internet of things) based projects. If you are a beginner when it comes to making projects then arduino is really your cup of coffee.
Step 4: Servo Motor
A servo motor is an electrical device that can push or rotate an object with great precision.
If we want to rotate an object at some specific angles or distance, then we can use a servo motor.
Orange Wire – Signal Pin
Brown Wire -GND
Red Wire – Power supply
Step 5: Ultrasonic Sensor
An ultrasonic sensor is used to measure distance by ultrasonic waves. The ultrasonic sensor head emits an ultrasonic wave and receives the wave reflected back from the target object. It measures the distance to the target (object) by measuring the time between the emission(transmitter) and reception(receiver).
The Required formula: Distance = ½ T x CT
= Time between Transmitting and receiving of the sound wave.
C = the speed of sound(340 m/s).
Step 6: 3D Parts
Step 7: Physical Building – Base Servo Motor
Insert the servo motor into the 3D printed parts.
Put screw along with servo motor in the 3D printed base parts.
Set the Servo motor angles based on the requirements.
Step 8: Physical Building – Fix Middle Part Servo Motor
This is the middle part of the Missile Launcher.
Place the servo Motor into the particular 3D printed slot.
Fix the screw along with the Servo motor.
Now Insert the Middle part of the missile launcher into the base of the base with the help of a screw.
Then tighten the screws along with base servo motor.
Step 10: Physical Building – Fix Top Servo Motor
This is the third part of the Missile launcher. Again take the servo motor and place it in a particular slot and insert the screw.
