My Engineering Portfolio

Robotics

In 2021, alongside my programming endeavors, I also delved into the realms of building, designing, and electrical wiring with the FTC robotics team Cryptic #20123, amidst the unique challenges presented by the coronavirus pandemic. This multifaceted role allowed me to leverage and expand my engineering acumen, demonstrating a keen ability to adapt and innovate in the face of new challenges.

My involvement in the design and construction of the robot encompassed a significant contribution to the assembly and computer-aided design (CAD) of key components such as the intake and drivetrain systems. Utilizing Autodesk Fusion 360, I created detailed technical drawings that meticulously outlined the robot's dimensions. This process not only required a deep understanding of mechanical design principles but also an ability to visualize and execute complex structures in a virtual environment, showcasing my proficiency in leveraging CAD tools for precision engineering tasks.

The electrical wiring aspect of my role demanded a thorough understanding of electronic circuitry and the seamless integration of various components to ensure optimal performance and reliability of the robot. I was responsible for wiring the control system, sensors, and actuators, ensuring efficient power distribution and signal processing. This responsibility highlighted my attention to detail, problem-solving skills, and an unwavering commitment to safety and functionality. It also underscored my capacity to work with intricate electrical systems, demonstrating an aptitude for electrical engineering within the multidisciplinary field of robotics.

Throughout this journey, my contributions in building, designing, and electrical wiring were marked by a meticulous approach to craftsmanship, an innovative mindset in overcoming design challenges, and a collaborative spirit in working alongside team members. These experiences not only enhanced my technical skills but also reinforced the importance of a holistic understanding of robotics, blending mechanical, electrical, and software engineering to create sophisticated, competitive robots.

Project Lead The Way (PLTW)

I have taken a few Project Lead the Way courses during high school, which provided me with a very strong foundation in engineering concepts and hands-on skills.

In Digital Electronics, I learned how to design and model circuits, research how electrical systems work, and then apply the knowledge in a practical sense to real projects. We constructed functional circuits, programmed microcontrollers, and even integrated these circuits into small robots.

In Computer Integrated Manufacturing, I studied robotics, hydraulics, and pneumatics. We saw the processes of manufacture: how to design and automate systems for applications in real life. I particularly enjoyed building and programming robots and using automation techniques to improve performance.

During my coursework in Principles of Engineering, some of the areas we covered included mechanics, structural engineering, and energy systems. This course really exposed me to a variety of engineering problems and shaped my skill set to be flexible.

In Introduction to Engineering Design, the students learned about computer-aided design tools and how to bring together technical skills and imagination in a project; from designing components all the way to creating prototypes, this course helped establish a strong base in design principles and problem-solving.

These PLTW courses have been the strongest in helping me understand engineering—certainly, to approach challenges with a hands-on, interdisciplinary perspective.

UMBC ITE

With the guidance of a distinguished professor, I was able to explore the intersection of computer science and engineering, specifically the integration of hardware and software systems. This included a design and programming exploration of hardware platforms: drones with Raspberry Pi 4 and C++, and RC cars controlled by Arduino. These projects further my understanding of the physical layer of digital systems, complementing knowledge in computer science.

By combining knowledge of mechanical and electrical engineering with machine learning and computer vision, I've developed autonomous systems that sense and interact with their environment. This synergy enables me to optimize software performance on hardware, creating innovative, reliable solutions. My interdisciplinary experience bridges the gap between software and hardware, equipping me to tackle complex challenges and contribute effectively to technology-driven projects.

Personal Projects

Outside of school, I have pursued my interest in robotics and engineering through hands-on projects and personal initiatives. The summer going into tenth grade, I started working on my own autonomous assistant robot. It has a tank drive chassis with tank threads, being powered by four GoBilda Yellow Jacket motors and controlled by a Pololu motor HAT. The core of the system is the vision sensors: Luxonis OAK-D Lite cameras, optimized for neural networks. I had chosen vision-based sensing after researching Tesla's lidar-free approach to autonomous driving during a research class on autonomous systems in inclement weather. The robot is based on a Raspberry Pi 4 with 8 GB of RAM. I am currently working on the autonomous system using vSLAM, and on top of that, I will use reinforcement learning to complete it. I expect this to be done this summer, and I intend to integrate OpenAI's chatbot API for in-depth interaction.

In addition to robotics, I've used my Raspberry Pi and 3D printer to bring various ideas to life. I have designed 3D-printed CAD models of such important monuments as the Shohid Minar in Bangladesh, the FIFA World Cup trophy, and other practical household items. These projects give me practice in CAD modeling and 3D printing—how to bring in the artistic with engineering feasibility. I also built a PC from scratch just for the fun of getting familiar with hardware components and assembly. These experiences underline my interest in using technology creatively, whether it be to help solve real-world problems or to come up with new ideas altogether.
