Development of Automated Guided Vehicle (AGV)
In the material handling industry safety has been a major consideration from the beginning and has only become more and more measured as liability and worker moral are taken into account. Ergonomics have also rewritten how employees are effected by the work they do. In current practice, the operators that works in a production line (especially in automotive plant) will have to give out their energy to manually push the trolley with an estimated weight that is nearly to 500kg. The trolley with the body frame needed to be deliver from one defined location to the next. It is believe that the current method applied is one of the effective way to bring the trolley to the next station. However, the push and pull forces that is applied to the skid or trolley with a heavy load may cause an ergonomics effects to the operators such as the Low – back Disorder (LBD). Manual material handling work has been reported contributing to a large percentage of MSDs annually. LBD is generally caused by cumulative effects of faulty body mechanics, poor posture, awkward movements and improper lifting techniques. The main objectives of this project is to fabricate an AGV by using appropriate material and process that is able to tow a trolley or skid with a load with an estimated weight of 500kg and accomplish a safe handling operations by replacing the operators with AGV. In this project, the AGV is fabricated accordingly through appropriate process such as welding, assembly and etc. This AGV responses and navigation is controlled by the microcontroller which is a device that act as the main brain. It has the ability to follow the black line as it guide path by using the IR line sensor and avoid the obstacles by using the ultrasonic sensor. The project implicates of fabrication of the hardware. AGV is, therefore, suitable for automating material handling in batch production and mixed model production,

How to Start your Large Motors- typical Solutions or new motor design?
In the context of low oil prices and an increasing demand for cost reduction of the electrical installations, optimizing the starting solution of high power electrical motors could be highly contributive. Direct on-line start is the most common solution today, being also the simplest and most cost-effective but it may generate voltage dip during start and stresses mechanically the machine and load. Progressive starting solutions, as auto-transformer, soft-starter or variable speed drive, solve the electrical and mechanical constraints in variable levels, related to their complexity. Today, in addition to the progressive starting solutions, motor manufacturers propose to design the motors as to reduce their inrush current, in some cases down to 300% of the rated current.
In this tutorial different solutions for large motor starting will be explored and compared, with respect to their application field, flexibility of adaptation, complexity during installation and set-up, overall performances and technical and economical aspects. Some guidelines for selection will be also discussed. In the scope of analyses are traditional methods, such as direct on-line, auto-transformer, soft-starter and variable speed drive and also recent solutions as motors designed with reduced inrush current.

IRAMY Inverter Control for Solar Electric Vehicle
Solar Electric Vehicles (SEV) are considered the future vehicles to solve the issues of air pollution, global warming, and the rapid decreases of the petroleum resources facing the current transportation technology. However, SEV are still facing important technical obstacles to overcome. They include batteries energy storage capacity, charging times, efficiency of the solar panels and electrical propulsion systems. Solving any of those problems and electric vehicles will compete-complement the internal combustion engines vehicles. In the present work, we propose an electrical propulsion system based on three phase induction motor in order to obtain the desired speed and torque with less power loss. Because of the need to lightweight nature, small volume, low cost, less maintenance and high efficiency system, a three phase squirrel cage induction motor (IM) is selected in the electrical propulsion system. The IM is fed from three phase inverter operated by a constant V/F control method and Space Vector Pulse Width Modulation (SVPWM) algorithm. The proposed control strategy has been implemented on the texas instruments TM320F2812 Digital Signal Processor (DSP) to generate SVPWM signal needed to trigger the gates of IGBT based inverter. The inverter used in this work is a three phase inverter IRAMY20UP60B type. The experimental results show the ability of the proposed control strategy to generate a three-phase sine wave signal with desired frequency. The proposed control strategy is experimented on a locally manufactured EV prototype. The results show that the EV prototype can be propelled to speed up to 60km/h under different road conditions.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
