Ball Sorter

We designed and developed a ball sorter capable of sorting balls of different colors, featuring a 3D-printed funnel, an acrylic laser-cut box, and additional wooden components. The system used a Raspberry Pi, a color sensor, a stepper motor, and a servo motor, and it was programmed to handle multiple balls at once, autonomously grabbing them one by one, detecting their color, and sorting them into the correct bin. One major challenge was designing the half-circle mechanism that moved the balls—it had to be positioned at a precise angle to ensure only one ball moved at a time without disrupting the others. Additionally, integrating the color sensor was difficult due to compatibility issues with one of our Raspberry Pi models, and calibration required fine-tuning to ensure accurate detection.

Autonomous Robot

I managed every stage of the project, from CAD design to prototyping, wiring, and final implementation. I programmed the robot using Python on a Raspberry Pi, utilizing gear motors and an H-bridge for precise motion control.

A two-button feedback system helped identify tube instability, allowing me to adjust the robot’s speed in real-time. I also determined the acceptable speed ranges for collaboration, balancing minimum movement requirements with maximum stability.

Although this was an individual project, I collaborated with others to test and refine the interaction between the two robots. By analyzing the performance of both systems, I ensured the robots could work together seamlessly while meeting all project constraints.

For my Human-Machine System Design class, I independently developed an autonomous robot that collaborated with another to transport a tube up ramps, dynamically adjusting speed for precise transport without sensors.

“Challenges”

One of the key challenges was ensuring the robot remained stable while moving up the ramp. Due to the use of two motors, the robot initially struggled to maintain a straight path. To address this, I added custom grippers to prevent the robot from falling off the ramp. I also stabilized the motors through extensive trial and error, fine-tuning their performance to make the robot’s movement as straight as possible.

Synchronizing two Python scripts was initially a challenge, which I resolved by calling one function inside the other to ensure smooth operation.

HAND MIXER

PRODUCT DISASSEMBLY AND CAD SOLIDWORKS ASSEMBLY

Collaborated with a team of three engineers to design and assemble a hand mixer using CAD. We took precise measurements and captured detailed photographs of the physical prototype to ensure accuracy. The entire CAD model was developed and the assembly process was executed successfully by our team.

Tawle

I analyzed different manufacturing methods and materials, balancing precision and durability. For example, while sand casting was ineffective for dice production, I proposed and implemented drill pressing as an alternative.

I led the CAD design, ensuring it aligned with the selected manufacturing techniques. Initially, we considered strip heating for the folding mechanism, but after realizing it caused sizing issues when folded, I adapted the CAD design to include both strip heating and glue gun reinforcements for the sides.

I emphasized working smarter, not harder, by stepping back to evaluate and refine our approach during the trial-and-error phase. This analysis ensured we resolved challenges efficiently and optimized our manufacturing process.

Acrylic Tawle

Collaborated with a team of four engineers to design and manufacture a custom backgammon board (Tawle) with all components. I actively participated in every stage of the process, including CAD design, material selection, laser cutting, sand casting, strip heating, and assembly.

Product Re-Design

In my Human Factors Product Design class, I redesigned a water bottle to enhance ergonomics and innovation. I applied the Climber model and the Transversal Design Method while researching patents, articles, and industry standards. My solution features an ergonomically designed grip for comfort, a hygienic retractable straw for easy storage, and a removable bottom that, after being frozen, keeps the bottle cold for up to 12 hours—ensuring cold water even without access to ice or refrigeration.

Assembly and CAD

Assembled and created 16+ components in SolidWorks, optimizing the design for manufacturability toreduce potential assembly time by 20%, while also creating engineering drawings and animating the assembly.

Design and Dine

Collaborated with a team of four to develop a personalized meal-generating app using SQL, HTML, JavaScript, APIs, and CSS. The app allowed users to input available ingredients, exclude unwanted ones, and receive quick, customized recipe suggestions, improving meal planning efficiency by 40%.

I identified and integrated the appropriate API, ensuring seamless communication between the database and the website. When the initial API was insufficient, I researched and implemented a better alternative to meet user needs.

Industrial Design + Prototyping

In my industrial design class, we are working on everything from hand sketching to rough editing in Photoshop to prototyping. For this assignment, we developed mice for Google. We started by analyzing the persona and conducting research to understand user needs. I then created a prototype using clay to refine the design.

Drawings, CAD and Sculptures

My mom is an artist, and growing up, I was taught that the sky was the limit. Here’s a glimpse of my creative journey, featuring my drawings, sculptures crafted with acrylic, wood, and plaster, as well as some CAD designs.
