OBJECTIVE

Rapid and reliable information networks are a significant part of today’s military operations. It can be said that vehicle-mounted sensor technology is changing the result of any battlefield and illegal attempts, provides vital information for both force projection and force protection. Hisar Border Protector is reliable and easy to operate. The major objective of deploying Border Surveillance Systems was provided constant protection an entire nation with LEGO EV3 components and was also determine any objects such as human, vehicle where was close to the critical area. Then, if needed, the movable and (S1) stable ultrasonic sensor calculate the velocity of objects no matter wherever it comes. Later on, Hisar warhead mounted them over the (M1) movable sensor, will be locked on the target’s line route map after learning the velocity of the object. After firing data computation, foot slope-mounted medium motor turns the ramp which is deployed 45-degree horizontal plane. Next, the supervisory control system launches a bomb to object.  Finally, the warhead will try to shoot the target properly to stop illegal attempt against the border lines.

BACKGROUND

This study was set out with the aim of assessing the importance of Border Monitoring Technologies in with LEGO EV3 education box. An initial objective of the project was to set a border monitoring system as if it were in really at the border. That was what we dreamed and created that system. To begin with, before setting the system, we made an algorithmic diagram included system preferences, materials, design and operation principles such as measurement of the margin of error individually. Afterward, we reconstituted our ideas. What was surprising was that we did not need any materials except for EV3. It was an innovative way to establish a complex system.

DESIGN AND TEST PROCEDURES

The role of us is to observe and decide what kind of design would be ergonomic and clear. After researching, we separated into three sections in order of design, report, and code algorithms. To begin with, we only used Lego bricks to establish a platform that carries whole the systems included large, medium motor, ultrasonic sensor. On the platform, we tilt the large motor and triggered with a cross stick. Afterward, ultrasonic sensor and medium projectile ramp are settled on the shaft.

This video shows the projectile motion of the system. It did not shoot the target but at the end the day it was successful.

                     

1-The scanner turns left and right sides with the angle of 63° until it detects an object within the scan area.

2-     After the detection, movable ultrasonic sensor starts a timer, then after the stable ultrasonic sensor detects the same object and stops the timer. Afterward, the velocity of the object is calculated.

3-     Since the program knows the velocity of the object, launcher platform deploys itself inbound or outbound route with the angle of 43°.  In addition, the program is coded to deploy the ramp in a parallel route with the enemy object.

4-    By the time the object has arrived the area the ping pong ball will have struck the object.

 Test procedure 
This graph shows our launch testing results according to different powers.

With the help of this graph, we concluded launch distances within the security zone.

The highest stand-off distance is 90 centimeters with the power of 55 and the angle 100°.

We also considered the calculation of the distance of the closest object and at about 30 power the ramp launches the ball about 34 centimeters.

RESULTS AND DISCUSSION

We succeeded shooting two of third objects after several attempts of tests.

The illegal attempt defense challenge is an engineering challenge and that is what we do best. We failed about a hundred times, but failure is not fatal; it is the courage to continue trying. After several tests, we achieved the exact shot and accuracy. A fair, strong defense system in an important part of civilized society. What we learned is that we learned how to handle technic problems in terms of sensors of Lego and decreasing the errors to a minimum is difficult but not impossible. Moreover, we learned that drawing flowchart is an integral part of problem-solving in this project. When it comes to design, we need to determine the essential ways of attaining our aims. That is why, in the beginning, the design of the system was one big drawback, but it was handled by changing the platform structure. Unlike other rivals, we did not use any non-Lego pieces, so it proves that we use the sticks wisely. The numerous changing on code blocks took more and more times. The software was pretty good works after a little tweaking.

CONCLUSION

In conclusion, we are pretty excited about sensors and how they help us manage the world around us by extending our human senses. LEGO EV3 provides the opportunity of learning how the sensors work and the lessons which applied mathematics and physics are really effective to cover issues extensively. This project plays a key role for the understanding of real problems clearly as in the real world most of the countries are protecting their borderlines such these systems. In today’s world, bombs more powerful than the previous ones and can annihilate the whole cities. Moreover, yesterday’s tools are not suitable for today’s problems in terms of military. We have to see the whole picture in any critical situation and it also requires an integrated approach such as receiving data from satellites. When it comes to reliability, it must be shot the target without overshooting. In addition, the ability to detect and war for small incoming objects is vital for the protection of civilization. In the military, radar systems developed with high technology and fully integrated with each system. As mentioned by Lockheed Martin (2018), infrared and ultrasonic sensor systems provide advanced observing targets. Last but not least, success in this competitive area depends on crucial teamwork. We partly succeeded by virtue of hard work rather than talent or copying the projects on the Internet or YouTube.
