Auto Shooter to Object With Radar and Arrow- Box

In this project I tried to make a system of electronics capable of detecting upcoming object(enemy) with radar(sonar). After object is detected an arrow -bow mechanism will calculate the position of the object and shot it down by arrow.

The whole project can be divided into 3 stages:

1) Make a radar using ultra sonic sensor, servo motor and a software ( Here I use MATLAB)

2) Make a arrow bow system capable of shooting arrow in any particular direction

3) Use the data from the radar and give direction to the arrow bow mechanism

Tools and material required are :

1) Wood sheets (3mm)

2) cutter

3) 1 arduino uno

4) 3 servo motor

5)1 HC-05 ultra sonic sensor

6)1 laptop

7) jumper wire

The Radar or sonar is made with ultrasonic sensor and servo motor. The servo will rotate by 180 and hence sonar will cover 180 degree. The scan inputs are plot in MATLAB.

The sensor connections are given below.

The MATLAB code is also provided below:

when the radar will determine the position of the object , it will send the data to arduino, and arduino will send required input angles to servo motors. The mechanism of the arrow bow is given .

After receiving all the data input from radar , arduino will control the arrow bow system . The servo attach with Ultrasonic sensor will stop at it's position as soon as it detect something near 20 cm. Then the arrow will point to this direction and after confirmation of an object it will shoot arrow. But if it finds object is not in the position the servo will again starts to work.

Code of the arduino is given below:

Connect the sensors and upload the code. Run the MATLAB code .Place something within 20cm of the ultrasonic sensor.

1) Radar servo---- pin 10;

2) Base servo of the arrow bow--- pin 11;

3) Trigger servo -- pin 9

4) echo pin --- pin2

5) trig pin --- pin3
