My name is Esha, and I'm an engineer.

I sketch, build, design, and create things that I'm passionate about and proud of. I am constantly trying to deepen my understanding of what it takes to bring a great idea from concept to reality, and I've learned a few things. Based on my experiences, I believe collaboration is essential. Great ideas will always face seemingly impossible obstacles, but with honest, open communication, and a lively exchange of ideas, I've found that most of those obstacles don't stand a chance!



I attended Carnegie Mellon University in Pittsburgh and I now live and work in Michigan. From sailing on Lake Huron to racing up Sleeping Bear Dunes, I am definitely loving experiencing what Michigan has to offer! In my spare time, I like to play board games and read in sunny spots. I've re-read the Harry Potter series a great many times, and I am a big fan of the moral fiction genre (championed, in my opinion, by Jodi Picoult).

                The Task

                Create a hands-Free Interactive Maze with Arduino and Kinect

                Design

                For Senior Design Capstone, I was part of a team of engineers who wanted to create a product with purpose. After some market research, we found that long term hospital patients do not have many options for entertainment. To address this issue, we chose to design a hands-free interactive game experience. Our product components included: base, a controllable robotic three link arm, and a cut out maze to navigate through. By integrating all of the components, we were able to have an easily controllable game. The user is able to simply wave their hand and begin guiding the robotic arm’s end effector through the maze.

                Execution

                Mechanical: The structure of the project included: A wooden base to house the Kinect and support the robotic arm and maze structure, a three-linked arm composed of laser cut acrylic, and a laser cut wooden maze with an acrylic enclosure for the arm.

                Electrical: The three-linked arm has a servo motor at each link, with the bottom-most motor attached to the base. Each of the motors are hooked up to an Arduino Mega along with a Kinect.

                Controls: We used an algorithm which separates the Kinect’s field of vision into 9 distinct areas. Each movement sensed by the Kinect is sorted into one of the 9 areas and then categorized into Left, Right, Up or Down. Based on the direction signaled by the user, an embedded 2D array is accessed which acts as a point to point maze database. This database holds the positions of each servo at each point in the maze. In the event of mass production, various mazes would be available with an according database available to upload. As the servo positions are accessed, the three corresponding joint angles are set for the required cartesian coordinate position in the maze.



                During the Capstone Design Showcase, this project was awarded the honor of “Most Innovative Design”.

                The Task

                Build a chromatic temperature display using LEDs, Arduino, and a temperature sensor

                Design

                The intent of the project was to create a visual temperature display. I used a pair of Arduino Unos and a strip of Adafruit Neopixel RGB LEDs to create an LED temperature gradient based on the temperature outside.

                The LEDs are installed into an infinity mirror, showing a bright tunnel colored according to the external temperature. For example, when the infinity mirror is a shade of blue, a greener blue indicates a temperature in the high 30s, while a truer blue would indicate a temperature in the low 30s.

                Execution

                When beginning this process, I focused on testing one system at a time, and then assembling all the components for the final product. I started with testing the transmitter and receiver modules by wiring them each up to an Arduino and sending a simple message over.

                Then, I prepared the LED strip for wiring and hooked the strip up to the receiver circuit and tested various color patterns. I was new to the Adafruit Neopixels so I had to do some troubleshooting due to some erratic light behavior which turned out to be due to lack of a common ground with the microcontroller.

                I built the infinity mirror illusion with a piece of glass, mirror tint, a shadowbox frame, and a mirror. The LEDs were inserted between the glass and the mirror, creating a tunnel effect as some light escapes through the tinted glass and the rest reflects back.

                The Task

                Create personalized and unique gifts by laser engraving wood

                Design

                Using the facilities at the local TechShop, I was able to translate vector images of ship designs into Adobe Illustrator for an assortment of engraved beads. For another project, I used Adobe Illustrator’s store of fonts to create a personalized message design for a cheese board.

                Execution

                With the laser cutter/engraver, I executed multiple passes of etching into wooden beads after test runs on scrap. The result was a bracelet of double-sided wooden beads with assorted sailing images engraved into them as a gift to an avid sailor.

                The personalized cheese board was an engagement present. It was designed in Adobe Illustrator and executed in a similar fashion to the wooden beads.

                The Task

                Design an entertainment experience for the citizens and tourists of a chosen city

                Design

                I was the team leader of the group which entered the Disney ImagiNations competition in 2012. As a response to the contest prompt, our experience was a water ride in Bogota, Colombia. The ride experience was based on the legend of El Dorado.

                Our created immersive experience allows guests to be a part of the legend of El Dorado. We believe that this will complete Bogota’s promotional scene, increasing tourism.

                The attraction is a dark ride that incorporates a combination of thrilling roller coaster experiences and an engaging and interactive show. The attraction design incorporates 3D imaging, special effects, and projection technology in order to immerse and engage the guest fully in the experience.

                Execution

                The Story: Hidden from the rest of the world, there lies a magical city of gold, long ago charged with maintaining the balance of the elements on earth. This city is El Dorado. It is ruled by an Entrusted Protector, who commands the magic of El Dorado to keep the earth in balance. Tyba is the current Protector. He was trained by his predecessor, and now he must train Sua, who is to be his successor. However, Tyba has grown power-hungry and his magic has been corrupted. El Dorado’s magic must be maintained by one who is pure of heart, and Tyba’s corruption has sent the elements into disarray and destroyed the balance of Earth. Sua, with her rudimentary magical abilities, has tried to right Tyba’s wrongs, but to no avail. Her magic alone is not powerful enough to restore balance. Sua decides she must get help if they are to save El Dorado and the world. They embark on a search for true believers.

                These true believers are our guests! In order to save the city, guests must help Sua to battle against the corrupted elements with their pure magic.

                We conceptualized and modeled ride carriages which housed four seats, one for each element, earth, wind, fire, water. Each has an interactive orb which allows the guests to interact with, and affect, the storyline. It is designed to be built with haptics that provide feedback to the user so that he or she truly feels as if they are using their natural elements’ power to help save El Dorado.

                Won honors for lowest weight and lowest cost

                The Task

                Build a lightweight and affordable apparatus that can grip and swing a billiard ball

                Design

                For this project, we were tasked with designing and constructing a lightweight and cost-minimizing apparatus that would, upon experiencing an applied torque from a motor output, grip a billiard ball and sustain its force while swinging in a 180 degree range. As a group, we evaluated the optimal points of contact of the apparatus to the ball, along with material-minimizing shape of the pieces. We laser cut acrylic for the main pieces of the body and used a 3D printer to print a spool that would pull the rotating arm closed.

                Execution

                In the first round of design the mechanism functioned perfectly in terms of the project task. However, upon analyzing the components, it was determined that there were multiple areas for design improvement.

                Upon redesign, the prototype met the functional requirements as well as the first prototype, but further met project goals of weight and cost. Our design was awarded both available honors of lowest weight and lowest cost of prototype.

                First place

                The Task

                Build a booth based on the theme 'A Fractured Fairytale'

                Design

                Annually, Carnegie Mellon students organize and attend a campus event called Carnival. During this time, organizations build and present 1-2 story structures which tell a story based around a given theme.

                What goes into it?
                Everything from CAD models of the wall frames, to wiring electricity through the building, to external aesthetics, to interior models, is essential to the booth. These and more are included in the yearlong preparation for the competition.

                This year’s theme, Fractured Fairytales, inspired me to create an alternate reality for the world’s favorite elephant, Dumbo! In this world, Dumbo has normal-sized ears, but wishes, hopes, dreams of flying. With some help from his friends, he manages to construct wings and make his dream come true!

                The booth has an indoor and outdoor area, the indoor area telling the story of Dumbo and how his story progresses until, in the outdoor area, the guests see Dumbo’s workspace and help Dumbo build his wings with an interactive puzzle.

                Execution

                As the Design Chair for the booth, I worked with the Management Chair to develop build plans for a one-story, two-room booth with a sunroof.

                I personally oversaw and helped develop interior design, create interactive components, and design the exterior walls of the booth. On the exterior of the booth, we had an Impossibility Board on which guests could write down what they considered impossible. Our aim was to get our guests to see Dumbo's journey and learn that anything is possible! Additionally, I designed many character wooden cutouts that were then painted by our team and hung up on the interior and exterior of the booth. The most complicated of these was an 8 foot tall cutout of elephants balancing on a circus ball surrounded by Christmas lights embedded in the wall behind it.

                This booth was awarded first place in its category!
