scholarly journals Voice Controlled Car using Aurduino and Bluetooth Module

This project builds a voice controlled car that can be controlled by voice commands which reacts in accordance to the corresponding voice command. However noise and distance handling require future development. Simple voice commands like left, right, forward, back, stop are used to run the car. These commands are given to Bluetooth module via an android application. The Bluetooth module and control unit are combined to store and test the voice commands. When an instruction for the automobile (car) is identified, a command message is sent to Arduino UNO, the Microcontroller of the car by the Bluetooth device. This command is analyzed by the microcontroller and followed up. In the vehicle, Image processing can be utilized to become aware of the shade and the obstacles. This work has been limited to the ZigBee system in the short-range (100mts range), and is linked to the car over long distance via long-range modules.

The paralysis that occurs in the human limbs can be caused by strokes, injuries, age problems, and ligament damage. The purpose of this study is to design a hand exoskeleton as rehabilitation in patients who have had a stroke in hand. The contribution of this research is to design a hand exoskeleton with a control system to control mechanical movements using voice command so that it can be used by patients who have a stroke. To be used by patients who have a stroke, the researcher designed a control system using voice pattern recognition so that patients who have weak myoelectric signals can control the mechanics easily. This device uses the voice recognition module V3 as a voice command to control open and control close mechanical movements. This device is capable of recording and running commands directly by using the push button, which consists of a start, save, reset, open command record, and close command record. In the open command obtained an accuracy value of 97%, the close command obtained an accuracy value of 93%. The results showed that the voice commands given had an average accuracy rate of 95%. The results of this study can be implemented as a rehabilitation device for people who have had a stroke to try to mimic human hand movements.

Dependency for mobility of physically challenged and visually impaired people is a major issue to be focused. To bring a safe and independent movement, we have designed and developed a mobility aid to assist them in locomotion. The device is designed using CATIA software. Our ideology is to control the navigation of the device by two modes. In the first mode, the navigation of the unit is governed by the voice command given by the user namely right, left, forward, reverse and stop. In the second mode, the device renders a reliable movement in the known environment which is achieved by feeding in a pre-defined layout. The navigation modes are regulated by a control unit.

An automatic identification method for the cane-end of sugarcane based on digital image processing is given considering the characteristic of the cane-end of sugarcane. An image processing method with Visual C++ is used in the dynamic acquisition and jitter procedure, and identifying the cane-end automatically. The identification system of the cane-end of sugarcane consists of the image acquisition unit, the image processing unit, the identification and control unit. After the digital image of a cane-end is collected, the identification system locates the edge between the cane-end and the body of the sugarcane immediately and automatically via image processing and identification, providing the location information of the cane-end for the following mechanical cane-end cutting method. This system can massively improve the productivity of the cane-end cutting mechanism in a sugarcane harvester.

The modern “Anti-Access/Area Denial” A2/AD systems are defined as a combination of all possible measures that can limit the ability of a potential opponent to enter and occupy a given area (operational theatre). Their action relies, among others, on radio-electronic disruption of digital guidance systems, communication, command and control systems, shooting down long-range maneuvering missiles, drones, and aircraft. The primary assumption of the anti-access concept is to deprive the enemy of the possibility of entering a given operational area (A2 – Anti-Access) through long-range destruction and depriving them of freedom of action in that theatre (AD – Area-Denial) by medium and short-range weapons. The Surface-to-Air Missiles (SAM), Anti-Ship Ballistic Missiles (ASBM), and Anti-Ship Manoeuvring Cruise Missile (ASCM) are used to carry out A2/AD tasks. Field artillery has also been used recently, particularly the Long-Range Precision Fires (LRPF). The purpose of the article is to determine the chance of using field artillery against the A2/AD systems. According to the authors, the NATO forces will lose control in the air in the first period of the conventional conflict with an equivalent opponent, and its rapid recovery will be a priority. Field artillery, as a weapon with ever greater possibilities of precise and deep destruction, can become a decisive factor, allowing dominance of A2/AD systems and enabling the implementation of tasks of its air-force and army aviation, as well as ground forces.

Management and Command253 are two different words and terms, but military structures use them as synonyms. Military commanders’ authorities are almost equal in meaning to civilian managers’ privileges and power. Comparison between military command and the civilian management system structure, organization, and way of work shows almost full identity and overlapping. The highest in scale and size military systems are national ministries of defense and multinational military alliances and coalitions. Military systems at this level combine military command structures with civilian political leadership and support elements. Therefore, they incorporate both military command and civilian management organizations without any complications, because their nature originated from same source and have similar framework and content. Management of organizations requires communication in order to plan, coordinate, lead, control, and conduct all routine or extraordinary activities. Immediate long-distance communications originated from telegraphy, which was firstly applied in 19th century. Later, long-distance communications included telephony, aerial transmitting, satellite, and last but not least internet data exchange. They allowed immediate exchange of letters, voice and images, bringing to new capabilities of the managers. Their sophisticated technical base brought to new area of the military command and civilian management structures. These area covered technical and operational parts of communications, and created engineer sub-field of science, that has become one of the most popular educations, worldwide. Communications were excluded from the military command and moved to separate field, named Computers and Communications. A historic overview and analysis of the command and management structures and requirements shows their relationships, common origin, and mission. They have significant differences: management and control are based on humanities, natural and social sciences, while communications are mainly based on engineering and technology. These differences do not create enough conditions for defragmentation of communications from the management structures. They exist together in symbiosis and management structures need communications in order to exist and multiply their effectiveness and efficiency. Future defragmentation between military command and communications will bring risks of worse coordination, need for more human resources, and worse end states. These risks are extremely negative for nations and should be avoided by wide appliance of the education and science among nowadays and future leaders, managers, and commanders.

Recent market studies show that the market for remote monitoring devices of different medical parameters will grow exponentially. Globally, more than 4 million individuals will be monitored remotely from the perspective of different health parameters by 2023. Of particular importance is the way of remote transmission of the information acquired from the medical sensors. At this time, there are several methods such as Bluetooth, WI-FI, or other wireless communication interfaces. Recently, the communication based on LoRa (Long Range) technology has had an explosive development that allows the transmission of information over long distances with low energy consumption. The implementation of the IoT (Internet of Things) applications using LoRa devices based on open Long Range Wide-Area Network (LoRaWAN) protocol for long distances with low energy consumption can also be used in the medical field. Therefore, in this paper, we proposed and developed a long-distance communication architecture for medical devices based on the LoRaWAN protocol that allows data communications over a distance of more than 10 km.
