Robotic vehicles and their applications have gained widespread significance in recent times in order to automate every sphere of human activities. Besides, it invites a great deal of attention in environments where human presence or intervention becomes very difficult and in most cases not being possible. The paper therefore proposes a voice based movement and evolves a direction control scheme for a robotic vehicle in a Light Fidelity (LiFi) medium with a view to exploit its available enormous bandwidth. Choice of Li-Fi as a medium owes to its quick response time and ability to respond to voice based commands. It engages the role of an artificial neural network (ANN) for recognizing the syllables through Levenberg-Marquardt training algorithm. The scheme relies on two sets of instructions issued to the vehicle controlled by the arduino controller, which allows acting in accordance to the instruction recognized by the voice recognition module.

This paper presents the design and the implementation of a smart irrigation system supplied from solar energy using off-shelf components as part of a senior design project. Introducing smart irrigation technology enhances the effectiveness of water utilization and will help farmers make their activities more beneficial. In addition, it is to increase the agriculture sustainability in common and considering the characteristics of irrigation in the rural areas. This paper brings forward new device based on wireless networks such as solar photovoltaic technology, arduino-based controllers, transmitters, receivers, and sensor nodes are used to measure soil moisture, humidity, temperature, and the sensor readings are transmitted to a remote station. Experimental results indicated that the developed system could provide a sustainable solution to enhance the efficiency of water use and to preserve it in the agricultural fields while using solar photovoltaic energy as a renewable power supply.

Robotic vehicles have been actively researched in recent times to automate most of the commercial applications to ease the daily life of consumers. Robotic automation has been an integral part of industrial concerns drastically reducing the manpower and effort needed for various processes. They are mainly based on RF communication, the spectrum of which is quite scarce. This has necessitated alternate means of providing communication paths for robotic vehicles. Light fidelity (Li-Fi) is a rapidly emerging technology exploiting the optical properties of abundantly available light energy. In spite of being limited by a line-of-sight communication unlike RF, they do not provide any hazards as well as quite suitable for small- to medium-scale indoor communication. This research article has proposed a Li-Fi based robotic vehicle controlled by voice commands issued from instructors. Voice recognition is achieved using MFCC-NN model, while the light energy is collected by a solar panel replacing the conventional photodetectors. The efficiency of the proposed work is established after observing superior performance for a wide range of experimentations done. The characteristics of light propagation through different glass medium have also been investigated justifying their probable utility in a small-scale business environment.

We present the design of smart and dynamic floral clothing accessories. The statement "smart" represents the floral clothing accessory that is able to sense the signals coming from the surrounding and makes responds, or is executed with the preset program. Besides, it could be remote control by using smart phone or computer. "Dynamic" means that the floral clothing accessory is able to show dynamic visual effects such as a flower blooming, branches swaying, light tracking just like a sunflower, or a butterfly wings waving. The main floral components of the product are a variety of flowers, leaves, branches and butterflies combined together. The products are operated by SMA actuating mechanisms, arduino controllers, and various sensors. The prototype of the products have been developed and can be realized in clothing application in the future, which will bring new features for daily clothing to add more highlights and fashion.

It becomes essential to run AGV at a constant speed or RPM in the plant to reduce downtime and lead time. Fuzzy logic controller and PID controller are applied to achieve constant RPM in AGV. AGV contains DC brushed motor with encoder, motor driver, microcontroller and battery. Encoder gives feedback to microcontroller in the form of shaft position. Microcontroller reduces error in the system based on the parameters defined by the algorithms. The first phase of the paper gives brief information about the hardware, software and the algorithms. In the second phase of the paper, methodology for implementing the algorithm to the system is shown. In the final phase of the paper, results and discussions are mentioned based on the applied algorithms. Comparison between PID controller and fuzzy PID controller is also shown. Ziegler-Nichols Algorithms is used to find PID parameters. MATLAB simulink and fuzzy logic tool box are used for simulation. arduino Microcontroller is used to accept the feedback given by the encoder and to control the speed of motor. In a nut shell, these control strategies help AGV to run at a constant RPM with reduced settling time, steady state error and overshooting.

This paper develops a Net Zero Energy Building (NZEB) prototype with renewable energy integration applications. Most of the power generated by the utilities is consumed by the domestic loads and with urbanization;energy demand is continuously increasing in developing countries like India. To meet the ever growing demand, generation has to be increased and thereby transmitted over long distances which results in increased system losses reducing the overall system efficiency and reliability. Generation addition by non-renewable sources would increase the greenhouse gas emissions caused by the additional consumption of fossil fuels. Towards addressing this problem, there is a lot of scope for researchers to increase the overall system efficiency and reliability and also to preserve the fossil fuels for future generations. One solution is by adopting Net Zero Energy Building (NZEB) concept which includes integration of renewable energy generation (like solar), intelligent controllers, Internet of Things (IoT) etc., for home energy automation. NZEB concept ensures that the loads of a building are controlled in such a way that the net energy consumed from the utility grid over a period of time (monthly/annually) will be close to zero. The net energy is the difference of the energy imported from grid to the energy exported to grid over a period of time. In this paper the real time NZEB prototype is developed with appropriate assumptions using wireless sensors to achieve home automation with IoT.

Energy crisis and increasing demand for energy is the most important issue in today's world as demand for electrical energy increasing over the years. Conventional energy sources like fossil fuels are not only limited but also hazardous to environment. the production of electrical energy using clean, renewable sources, such as solar energy, wind energy, etc. Owing to the usage of solar energy, it has become necessary to develop some methods for the better use of solar energy.
