It is very dreadful that huge liters of excrement are being deposited into the rivers across our country. The pollutants and toxins are assisting the amassing of the toxicant in water thus affecting aquatic life. Only when the detritus floating above the water bodies become persistent, the governments' plan of action is set about and unfortunately by that time, the life cycle in that water body breaks. This research work focuses on deploying a solution for the unfavorable effects on the floating refuse, and henceforth reduces the pollution caused due to the unsettled wastes including plastics and plant weeds. The project aims to develop a waste collecting boat to scavenge the water body and abolish the floating waste. This is done by employing a conveyor belt connected to the front line of the boat. Boat movement is established using a remote control application by incorporating an RF module along with an encoder-decoder pair. This method will reduce the cost of operation because of less human involvement and labor. Major challenges in implementing the boat are compact mechanical design and reliable power supply. The principle feature of this boat is the collection of refuse and floating weeds from the surface of the water into a basket which is removable [2].

K. R. Jayasree, Jayasree P. R., and A. Vivek, “Smoothed RRT techniques for trajectory planning”, in 2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy), Kollam, India, 2017.[Abstract]


Trajectory planning of a car-like mobile robot tracking a moving target by avoiding dynamic obstacles is developed using Smoothed Rapidly exploring Random Tree (RRT) and Smoothed Bidirectional RRT techniques. Case studies are done in dynamic and static environments. Kinematic model is considered for the mobile robot. The model of the system and the path planning algorithm including all case studies has been simulated for both RRT techniques. The performance comparison of both methods are done and the required results are obtained in MATLAB.

Jayasree P. R., Prasad, V., and Sruthy V., “Active Power Sharing and Reactive Power Compensation in a grid tied photovoltaic system”, in International Conference on Processing of Materials, Minerals and Energy, 2016.[Abstract]


In the present scenario of energy crisis, researches on non-conventional energy sources have grown appreciably. The electrical energy derived from the PV panel is considered as the most useful natural resources. This paper deals with the operation and control of a grid interfaced PV system. Inverter control is achieved by using adaptive hysteresis current control scheme. The proposed inverter control technique interfaces renewable energy source and the AC bus of micro grid. It provides the possibility of injecting power from the renewable sources and favours reactive power compensation. The resulting controller is simulated in MATLAB/SIMULINK and results are analyzed.

V. Prasad, Jayasree P. R., and Sruthy V., “Hysteresis Current Controller for a micro-grid application”, in 2016 International Conference on Energy Efficient Technologies for Sustainability (ICEETS), 2016.[Abstract]


Researches related to non-conventional energy sources have grown significantly in the present scenario. The electrical energy from the PV panel is considered as one of the most useful natural resources. This paper deals with the operation and control of a grid connected PV system with a nonlinear load. A utility grid connection is provided in order to replenish energy levels in case of power shortage from the renewable energy sources. Hysteresis Current Controller is employed for the inverter control. The proposed inverter control technique interfaces renewable energy sources and the AC bus of micro grid. It offers the possibility to inject power from the renewable sources and also improves the power quality in the same micro grid. Simulation results show the effectiveness of the proposed inverter control technique in improving the power quality of the system.

There is an increased demand for electric bike in the market. This is due to the fact that the user is looking for increased comfort and also reduced price in present day scenario. So E-bikes are an extremely efficient and cost effective method to cater to all the needs of the consumer. Instead of investing money in a brand new model of bicycle, it is also effective to covert an existing model of pedal powered bicycle into an electrically powered one, which would be just as efficient as the new design, hence catering to all the needs and requirements of the consumer. The control of the E-bike is done by using chopper control and in turn by using an ATMEGA-32 microcontroller to regulate the analog input from the throttle. The motor drive used for the model would be a DC series motor. Hence the model of the electric bike would be simple in design as well as efficient. More »»

The output from the renewable sources fluctuates greatly depending on the weather conditions. A micro grid, complemented with a utility grid interconnection enhances the power handling capability in the event of power shortage from the renewable sources. For the synchronized operation of both the grids, a suitable power sharing strategy has to be devised with adequate control logic. Simulation studies showed that a hysteresis current controller for this purpose provide fast and robust dynamic performance insensitive to load variations. This paper details the hardware realization of switching control logic for the interconnecting inverter. The experimental results on a scaled down system using 50 V three phase ac source and 500 W, nonlinear load substantiate the simulation studies

A mobile robot shall efficiently plan a path from its starting point or current location to a desired target location. This is rather easy in a static environment. However, the operational environment of the robot is generally dynamic and as a result, it has many moving obstacles or a moving target. One or many, of these unpredictable moving obstacles may be encountered by the robot. The robot will have to decide how to proceed when there are obstructions in its path. How to make the mobile robot proceed in dynamic environment using SRRT technique in hardware is presented here. Using the proposed technique, the robot will modify its current plan when there is an obstruction due to an unknown obstacle and will move towards the target. The hardware model of four wheeled mobile robot and target are developed. The experimental platform is developed and control of the system is obtained using an Arduino UNO and Arduino Mega platforms.
