Military Robot Design and Implementation For Wireless Communication

TL;DR: In this article , the authors demonstrate how to use an ESP32-CAM module and a few electronic sensors to build a clever military robot to monitor border regions in a real-time computer vision workload.
Abstract: Robots are designed to carry out specialised tasks that humans are unable to do or in hazardous environments where human labour is not guaranteed. As a result, these kinds of vehicles can carry out tasks that are challenging for humans. Allowing a soldier the responsibility of surveillance in such circumstances is challenging since it could endanger the soldier's life. Instead, we can utilise a robot to monitor border regions. In this project, we'll demonstrate how to use an ESP32-CAM module and a few electronic sensors to build a clever military robot. Although the ESP32-CAM is a low power and low latency video streaming module and has GPIOs and serial connection, it does not appear powerful enough to handle some demanding real-time computer vision workloads.

TL;DR: To enable an optimal PV design parameter estimation there is an inevitable need to incorporate either evolutionary computation schemes or apply an efficient multi-objective optimization measures.
Abstract: Solar energy has been one of the environmental friendly sources of energy. The low cost solution with minimal maintenance motivates towards photovoltaic (PV) cells based energy harnessing methods to meet energy demands. However, majority of conventional PV systems suffer from low energy conversion ratio (ECR) due to improper selection of the PV parameters and maximum power point tracking (MPPT) algorithm. Even ECR is adversely affected under varying environmental conditions. Therefore, accurate estimation of PV parameter can be of paramount significance for efficient PV model design. In addition, the development of a robust MPPT algorithm in conjunction with the effective PV design parameter can enable optimal ECR achievement. In this review paper, a number of literatures pertaining to PV parameter estimation and MPPT algorithms are discussed. Different methods including analytical, iterative and evolutionary computing algorithms are assessed for their efficacy towards PV parameter estimation. This review paper revealed that the analytical approaches suffer from singularity problem as well as limited mathematical calculation that confine its efficacy for optimal PV parameter estimation under dynamic irradiation pattern. The iterative approaches too are limited due to dynamic environment conditions. Our study has revealed that the evolutionary computing approaches, such as genetic algorithm (GA), particle swarm optimization (PSO), differential evolution (DE), etc. have played vital role in PV design parameter estimation and classical approaches suffer from local minima and convergence issues. This manuscript reveals that to enable an optimal PV design parameter estimation there is an inevitable need to incorporate either evolutionary computation schemes or apply an efficient multi-objective optimization measures. This as a result can not only alleviate local minima and convergence issues but can also enable swift and precise parameter estimation to assist optimal PV design and augmented ECR performance.

TL;DR: Low power high-speed hardware architectures for the efficient field programmable gate array (FPGA) implementation of the advanced encryption standard (AES) algorithm to provide data security and modified positive polarity reed muller (MPPRM) architecture is inserted.
Abstract: Nowadays, a huge amount of digital data is frequently changed among different embedded devices over wireless communication technologies. Data security is considered an important parameter for avoiding information loss and preventing cyber-crimes. This research article details the low power high-speed hardware architectures for the efficient field programmable gate array (FPGA) implementation of the advanced encryption standard (AES) algorithm to provide data security. This work does not depend on the Look-Up Table (LUTs) for the implementation the SubBytes and InvSubBytes stages of transformations of the AES encryption and decryption; this new architecture uses combinational logical circuits for implementing SubBytes and InvSubBytes transformation. Due to the elimination of LUTs, unwanted delays are eliminated in this architecture and a subpipelining structure is introduced for improving the speed of the AES algorithm. Here, modified positive polarity reed muller (MPPRM) architecture is inserted to reduce the total hardware requirements, and comparisons are made with different implementations. With MPPRM architecture introduced in SubBytes stages, an efficient mixcolumn and invmixcolumn architecture that is suited to subpipelined round units is added. The performances of the proposed AES-MPPRM architecture is analyzed in terms of number of slice registers, flip flops, number of slice LUTs, number of logical elements, slices, bonded IOB, operating frequency and delay. There are five different AES architectures including LAES, AES-CTR, AES-CFA, AES-BSRD, and AES-EMCBE. The LUT of the AES-MPPRM architecture designed in the Spartan 6 is reduced up to 15.45% when compared to the AES-BSRD.

TL;DR: The system focuses on using a Digital Signal Processor to process the voice commands and accordingly control the required appliance and XBee transceivers are used to eliminate the need for large amount of wiring between the processor and the appliances.
Abstract: This paper proposes an automation system where users can use voice commands to control their electrical appliances, such as light, fan, television, heater etc. The main aim is to help make the life of people more comfortable, especially for the elderly and disabled as they will not have to be actually present near an appliance to turn it on or off. The system focuses on using a Digital Signal Processor to process the voice commands and accordingly control the required appliance. XBee transceivers are used to eliminate the need for large amount of wiring between the processor and the appliances. Experimental results show that the system has a good response and is cost effective. We conclude that this system provides solutions for the problems faced by home owners in daily life and make their life easier and more comfortable by proposing a cost effective and reliable solution.

Abstract: During last two decades, security of the digital images apparently increased. This paper involves Knight Tour Path Scan Pattern and Henon Map methods to encrypt an image. The basic idea used in the proposed algorithm is that the plain images go through pixel-level and bit-level shuffling operation followed by diffusion process. With the help of knight tour path scan pattern, each 8*8 block of the plain image arbitrarily permuted and to enhance the security of image bit-level permutation also involved in the proposed algorithm where every pixel bits are shuffled according to mutation rule. In the diffusion operation, a bitwise exclusive-OR operation applied between bit-level permuted image and random sequence generated from henon map. The strength of the proposed algorithm is to reduce the high correlation and produce the secure cipher image.
