The “Automatic Weapon/Defense System” represents a state-of-the-art solution for threat detection and response in border areas and maritime environments. The project using a radar system excels in measuring distances and quickly identifying potential threats within a specified range. Once a threat is detected, an alert mechanism with a buzzer is activated to inform the system operator in real time. For a more affordable simulation of an expensive defense system, the project includes innovative components. An ultrasonic sensor serves as a cost-effective alternative to a radar system that effectively measures distances. HuskyLens takes care of threat tracking, constantly analyzing the movement of potential threats and ensuring accurate tracking. The warning system is triggered when threats exceed a specified range, approximately 40 cm in the simulation. The simulated firing sequence includes a manual control aspect where a system operator located nearby can trigger the firing mechanism after assessing potential damage. Weapon simulation uses a DC motor and threat tracking is facilitated by pan-tilt servos that provide stability during motion analysis. This cost-effective approach mitigates the high costs typically associated with implementing such defense systems. The project's innovative use of affordable sensors and simulation components demonstrates its potential for practical applications in real-world scenarios, promising increased safety and rapid response capabilities in critical areas. In order to simulate the project idea, it involves large and expensive machinery, so it has been scaled down to short distances. This approach allows to use more cost-effective components while maintaining the essence of the original concept.
