Solving the Problem of Vibrations in Auxiliary Lights
While I was working with the aftermarket accessories manufacturers as a freelancer, I had the opportunity to tackle a challenging problem: the vibrations of auxiliary lights when used off-road. These lights are very useful for off-road vehicles, but they often vibrate due to road undulations and other factors, which can defeat the purpose of using them.
To address this problem, I worked on designing and building a light mount for the LightForce XGT and Blitz lights. I used mild steel (MS) for the construction of the mount, and I incorporated a counterbalance behind the bumper and truss supports on the outside. I also added dampers to connect the ladder frame to the body, which enhanced the support without transmitting vibrations onto the body from the chassis.
This design was successful in eliminating most of the vibrations, and it was adopted by other vehicles within our close circle. I am proud of the work that I did on this project, and I believe that it showcases my ability to solve challenging problems and create practical and effective solutions.

These adjustments allowed for a better overall driving experience and improved the handling of the cars. Overall, the project was a success and demonstrated my expertise in car wheel alignment and the factors that affect its performance.
Electric Car for Last Mile Delivery
As part of my work at Invento Robotics, I had the opportunity to lead a team in the design and construction of an electric car. This 4 wheel drive vehicle was powered by 4 hub motors and featured a chassis that we designed and built in-house using square cross section members. The car was built for last mile delivery of food and commerce, as well as for use in warehouses to move goods.
One of the key features of our electric car is its ability to integrate with the autonomous navigation capabilities of the Mitra Robot. This allows it to navigate on its own and make deliveries without the need for a human operator. We also tested the car with a load of 200 kg, which demonstrates its strength and durability.
I am proud of the work that my team and I accomplished on this project, and I believe that our electric car has the potential to make a positive impact in the world of transportation and logistics. This project is a highlight of my experience and skills, and I am excited to continue working on similar projects in the future.
High-Performance Car Audio Systems
In this project, I have focused on designing and installing high-quality car audio systems in a variety of vehicles. Through extensive research and experimentation with different components, I have developed an in-depth understanding of their compatibility and how to create the optimal setup for the desired sound profile.
In order to customize the sound profile of a car audio system, various factors need to be taken into account, such as the type and quality of the components used, the acoustics of the vehicle, and the listening preferences and habits of the listener. By carefully selecting and arranging the components, and making appropriate adjustments to their settings and parameters, it is possible to create a sound profile that is tailored to the specific requirements and preferences of the listener.
One example of a system I have designed and installed is a single din head unit, Avatar Components on the front and JBL Stadium components on the rear, a Rockford Fosgate 4 ch class D Amp and Alpine PDX M6 Mono Amp, a Rockford Fosgate P3D212 Subwoofer with a custom-built side-firing enclosure, and a custom-built 4AWG wiring kit with parallel body ground. This setup was installed in a Toyota Innova Crysta, and features noise isolation and damping on all sides to produce up to 95 decibels of high-quality sound without distortion or vibration.
Throughout this project, I have gained extensive experience and expertise in designing and installing car audio systems. I have worked on a variety of cars and budgets, and have consistently achieved impressive results. This project showcases my passion for car audio and my dedication to achieving the highest levels of performance and quality.
Improving Car HVAC Performance with Flash Cooling
As part of my work in the automotive industry, I focused on enhancing the performance of a car's HVAC unit. The car's AC was only performing at 60% of its full capacity, and it took a long time to cool the car after it had been exposed to the sun.
To address this problem, I developed a flash cooling system that used a spray of water to cool the condenser. This improved the performance of the condenser and allowed the car to cool more quickly and effectively. I used a water tube with directed perforations to spray the water uniformly on the hot condenser, and I automated the process so that the spray would only activate when the condenser temperature was above a certain threshold.
Overall, this project was a success and demonstrated my expertise in improving the performance of car HVAC units. It made the driving experience more comfortable and enjoyable for car owners, and I am proud of the work that I did on this project.
CFD Analysis of Car Spoiler Aerodynamics
As a part of a mini project at IIT Madras, I used simulation in computational fluid dynamics (CFD) to analyze the aerodynamics of a car spoiler rear wing. I built a model of the car and the spoiler, and tested it for various angles of the spoiler to determine the lift and drag forces.
To carry out the analysis, I used CFD simulation software to create a virtual model of the car and the spoiler. This allowed me to accurately represent the shape and geometry of the car and the spoiler, and to simulate the flow of air around them.
I then ran simulations for different angles of the spoiler, and used the results to calculate the lift and drag forces on the car. This allowed me to see how the aerodynamics of the car changed as the angle of the spoiler was altered, and to understand the effect of the spoiler on the overall performance of the car.
Overall, this project allowed me to gain a deeper understanding of the aerodynamics of car spoilers, and to develop valuable skills in simulation and CFD. The results of my analysis could be useful for designing more efficient and effective spoilers for cars.
Engine Upgrade: Boosting the Power-to-Weight Ratio of a Motorcycle
In this project, I was part of a team that worked on improving the performance of a 150cc bike by swapping its engine with a larger 200cc engine. The main goal of this project was to increase the power-to-weight ratio of the bike, which would improve its acceleration and overall performance.
To achieve this goal, we first designed custom engine mounts that would securely hold the larger engine in place. We used flat metal sheets for the construction of the mounts, and we bent, cut, drilled, and welded them to create the desired shape and structure. This process required a high level of precision and attention to detail, as the engine mounts needed to be strong and durable, yet lightweight and compact.
Once the engine mounts were ready, we proceeded to install the engine, the feeling system, the air intake, and the upgraded exhaust. We also modified the wiring to accommodate the changes in the engine and the other components. This required us to carefully disassemble the bike, remove the old engine and its associated parts, and install the new engine and its components. We also had to make sure that all the connections were secure and properly sealed, and that there were no leaks or other problems.
After completing the installation, we tested the bike to see how it performed. We were pleased to see that the bike had a significant increase in performance, with a noticeable improvement in acceleration and overall speed. The engine was also more responsive, and it was able to deliver more power and torque than the old engine. However, we also observed a slight dip in efficiency, as the larger engine consumed more fuel than the smaller engine.
Overall, this project was a great learning experience for me and for my team. It allowed us to develop a range of practical skills, including design and fabrication, engine modification and upgrade, and teamwork.
Automatic Windsheild Wipers
As part of our engineering project, our team designed and built a prototype of an automatic windshield wiper system. This system is able to detect rain and start automatically, adjusting its speed and frequency based on the intensity of the rain and the vehicle's speed. This innovative design allows for a safer and more convenient driving experience, as the driver no longer needs to manually adjust the wiper settings.
To create the prototype, we used a combination of mechatronics, fuzzy logic, and embedded systems. We worked together to integrate the necessary mechanical and electrical components to control the wiper, and used fuzzy logic to enable the system to respond intelligently to different rain intensities and vehicle speeds. We also implemented IR-based sensors to detect the presence and intensity of the rain, allowing the system to adjust the wiper settings in real-time.
Throughout the design and development process, we faced a number of challenges and had to overcome them through collaboration and teamwork. For example, we had to fine-tune the fuzzy logic system to ensure that the wiper was able to respond accurately to different rain intensities and vehicle speeds. This required a significant amount of testing and iteration, and we worked together to find solutions and refine the system.
After completing the prototype, we attached it to the windshield wiper of an SUV and tested it in different rain conditions. We were able to achieve successful results, with the wiper responding accurately and reliably to the rain data it received. This included testing the system in both light and heavy rain, as well as at different vehicle speeds.
Overall, this project was a great learning experience for our team. We gained valuable hands-on experience with mechatronics, fuzzy logic, and embedded systems, and were able to apply these skills to create a functional and innovative prototype.
