IPv6 Deployment on Campus Network

This project focused on deploying IPv6 across a campus network to address the limitations of IPv4 and prepare for future demands. The transition involved implementing a dual-stack system where IPv4 and IPv6 coexisted, upgrading network devices, and configuring services like DNS and DHCP to support IPv6. The deployment aimed to expand address space, enhance security, and ensure the network was scalable and future-proof. Comprehensive testing and training were conducted to ensure a smooth transition, resulting in a modernised network infrastructure supporting the growing number of devices and emerging technologies.

The gravitational water vortex power plant is an emerging technology in the context of low-head hydropower, providing a suitable option for rural electrification. There is an opportunity for power generation in remote villages where it is difficult and economically not viable to offer the national power grid. Its simple design also allows it to be fabricated in local introductory workshops, allowing the design to be replicated worldwide. Thus, this project can act as an exemplar project for further improvements in the design of the gravitational water vortex power plant, which is a stepping stone for promoting the production of “green energy” by offering new solutions to existing problems through technical innovations. 

This project focuses on developing a versatile drone with a video surveillance system and a payload delivery and drop mechanism. The drone is designed to perform real-time aerial monitoring using a cloud-based IP camera, making it ideal for security and disaster management applications. Additionally, it features a robust payload delivery system that allows for the transportation and precise dropping of items, such as medical supplies or equipment, to targeted locations. By integrating these two functions into a single platform, the project aims to create a cost-effective, efficient solution for complex operations requiring surveillance and logistics capabilities.

The global use of solar photovoltaic systems is accelerating rapidly due to the ever-decreasing cost and improved cell efficiency. The variation in solar irradiance, weather conditions and temperature cause solar cells' non-linear output V-I characteristics. An efficient maximum power point tracker is needed to get maximum power from the solar array instantaneously. This study has implemented the incremental conductance MPPT algorithm in hardware and compared the result with a software model using MATLAB/SIMULINK. This algorithm automatically changes the converter's duty cycle connected to the solar panel so that the panel voltage becomes equal to the voltage equivalent to the maximum power point at any level of insolation, temperature or load conditions. It was found that the software-modelled MPPT algorithm increased the PV output by 38 %, while it was 33% in hardware implementation. The prioritizer embedded in the system optimises the use of solar power rather than the utility grid.

A line following a robot is a fundamental concept of an autonomous vehicle that follows a predefined path, which can be a white or black stripe with a distinctive background. The path may also be designed to be magnetic, so the sensor should be able to detect magnetic fields. In our project, a White line with 2.5cm width is used with a black floor. Using a line array with five sensors and a built-in comparator provides enough information to track the white line and smooth the movement precisely. The Arduino Mega Development board provides enough input pins to connect lines, obstacle/wall sensors and motors. The PID algorithm is implemented to control the robot's movement as smoothly as possible by tuning the algorithm appropriately. There are myriad applications for robots where there is limited access for humans and risk to human beings. Also, there is a tremendous possibility of autonomous vehicles with different kinds of techniques like cameras, Laser, Magnetic tracks, etc, considering safety.

The start-to-finish track where robots had to travel was hurdles, sand, pebbles, mud, and water, which represent the journey of a robot from Terai through hills and the destination at Mount Everest. The final part was to raise the flag. (Link:  https://www.youtube.com/watch?v=_gcXeWnCE7o) Robot “Nepali Keto” completed the track within two minutes and raised the flag 3.9m High. 

This project presents the design and implementation of a versatile robot capable of line-following and circular maze-solving tasks. The robot has sensors and algorithms allow it to navigate predefined paths and solve the maze. The line-following and maze-solving functionality is achieved using an array of infrared (IR) sensors that detect the contrast between the line and the surface, guiding the robot along the path with precision. The robot's hardware architecture includes a microcontroller that processes sensor inputs and controls the motor drivers for precise movement. This robot is a practical example of autonomous navigation, demonstrating the integration of simple yet effective hardware and software solutions for real-world applications in robotics. Potential applications include automated transportation systems, search and rescue missions, and educational tools for teaching robotics and programming concepts. The results of this project showcase the robot's ability to accurately follow lines and successfully solve a maze, highlighting its potential for further development and deployment in more complex environments.

This project presents the design of a Liquid petroleum gas (LPG) leakage detector for homes, offices and other areas where LPG is used. LPG in Nepal is contained in a pressurised cylinder and supplied via a regulator to the burner. The number of sudden death incidents increasing due to excessive LPG leakage has risen recently. Many cases are due to mishandling of cylinders, lack of maintenance, and use of faulty regulators. Based on that, a liquid petroleum gas leakage detector system has been developed using a gas sensor and logic detector circuit with a buzzer and LED, which signifies LPG gas leakage.
