Weapon Detection System in Remotely Operated ASV

High tensions within states or across borders are quite common nowadays. Protection of human resources i.e., soldiers is as important as the protection of national resources. It is a visible fact that the causality rate among the defense forces during a crisis is relatively higher. That is the reason why a majority of Governmental organizations of various nations are stressing the concepts of Automation. ROV or Remotely Operated Vehicle, a concept of automation, is playing a very vital role in almost all the advancements in this technologically developed society. Present work, one complete Armored Safety Vehicle (ASV) was designed with more featured to accommodate sensors for detection and coding are developed o detect the weapon using the image processing techniques. There is a special wheel design is introduced which is safe for easy and quick movement of a vehicle. From commercial vehicles to exploring the deepest trenches, ROV’s have been a substantial tool for developmental prospects. It was tested for one image file and worked well. It is integrated with Machine Learning and image processing concepts to automatically come up with solutions based on the inputs. These concepts when used in defense vehicles not only increase efficiency but also reduces the casualty rate during a crisis.


Introduction
The two major areas that have been continually evolving along with human civilization are transport and technology [1][2][3]. Initially, man invented wheels. He attached it for locomotion to a cart and then motorized it for comfort. Today, the need for automated vehicles with autonomous features is the need of the hour in the 21st century. So, they're computerizing it for robotics at the moment and energy estimation [4][5][6]. One of the most critical industries of a country is defence. They protect the country's territorial dignity and sovereignty. This automation is now strongly requested by the defence industries, as border disputes have been constant for a while now [7][8][9]. ROV is one of the implementations of this automation [10][11][12][13]. For the defense, the vehicle must have the features to attack the opponent and same time to easily identify the weapons from a longer distance. Safety is an important factor while designing the defence vehicle.

Remotely Operated Vehicle
For reconnaissance, surveillance and other combatrelated objectives, the Internet of Military Stuff (IoMT) is the use of IoT technology in the military domain. It is highly inspired by the future possibilities of urban warfare and requires the use of cameras, ammunition, tanks, robotics, humanwearable biometrics, and other battlefield-relevant smart technologies. The IoT-based operation will help in the control of the vehicle from a remote location [14].

Armored Security Vehicle
Armored Safety Vehicle (ASV) also known as Advanced Safety Vehicle are used in military operations to transport militants and weapons to a battlefield [15]. These vehicles when fitted with weapons are considered combatant vehicles. The combatant vehicles such as the M1117 Guardian developed by Textron Systems are used in defence operations in the United States of America.

Design
The ASV is designed in such a way that it can withstand multiple explosions while protecting the soldiers present inside. The unique hull design with oblique faces can withstand impact more effectively than vertical faces. The designed vehicle can accommodate about 10 to 15 people inside. The vehicle is provided with radar to detect incoming threats. The front LED wide lamp provides sufficient brightness to travel in rough terrains. The vehicle is also provided with a grapple system to sustain the vehicle on steep slopes. The front windshield is bulletproof one-sided mirror glass which helps the user to monitor the environment from inside while nothing can be seen inside from outside. The complete vehicle is modeled using commercial software and it is shown in Figures 1 and 2. The vehicle can be only operated by a single person in case of system malfunction. The vehicle is provided with an autonomous turret system with two barrels of 50cal each. The wheel is designed to provide mobility even after severe explosions near/on tires. For this case, we have increased the size of the rim such that the vehicle can move using rims as well. It is shown in figure 3.

Mechanism
The design is not provided with a suspension system as it can cause immobility in case of undervehicle explosions. The vehicle is powered by electric motors provided on each wheel. These motors are provided by battery modules. The battery module is made up of individual lithiumion cells. A single module can accommodate about 1000 lithium-ion cells. The default power source is 7 modules and can be increased up to 12 modules. The weapon detection system is used to differentiate military personal from terrorists. The military personals are provided with unique IR id tags which are used to differentiate them. A camera is provided in the turret system for weapon detection. The turret can be rotated up to 270 deg with elevation up to 15-20 deg. When a weapon is detected, if it is a terrorist the weapon system gets activated and eliminates them. For the weapon detection algorithm, we will be using YOLO object detection where will be training datasets for different weapon cases. The accuracy of the detection is based on the training of datasets.

In any detection system, there are sensors to identify the object and a camera to capture the environment. The captured images are to be sent for analysis as an image processing technique.  fig.set_size_inches(18, 10) plt.axis("off") plt.imshow(cv2.cvtColor(resized_image, cv2.COLOUR_BGR2RGB)) plt.show()

Similarly, using the sensors, it can identify the object. Based on the earlier experience, program coding is developed for the image processing and object detection system. From figure 5, it is image processing is done and it can capture that there is a weapon, and this information help to make proper safety and for the next action.

Conclusion:
Nowadays in countries or around borders, high tensions are very common. Security of human capital, i.e. the safety of troops, is as important as national property security. The fact that the causality rate is comparatively higher among the security powers during a crisis is apparent. It is quite substantial that the casualty rate must be low for a good military ally. In this analysis, a complete ASV vehicle is designed with all necessary parts. A special effort is spent on designing a wheel. A programing is developed to do image processing to detect weapons. These statistics and figures demonstrate the nation's resilience and the security sector's performance. The definition of ROV, therefore, is an important instrument for achieving this. ROV vehicles need minimum to no human intervention, making them very powerful in defense sectors to decrease the causality rate. The final design was arrived at after doing many analyses based on wind and the size of the vehicle. With these studies and modeling, a suitable and safe vehicle can be designed for defense application.
