>> In the summer of 2024, I was handed a broken 3D printer by Cofab Design and asked if I could turn it into a machine which lays adhesive along programmed paths. I answered yes, and began by opening it up to access the motherboard. After much poking around with a voltmeter, I found a small resistor hidden within the insulation of a wire. It failed my continuity test, so I replaced the resistor and re-soldered the connection. The serial connection I needed was now working.

I designed, modeled, and 3D printed fixtures which secured a microcontroller-based electronic fluid dispenser (EFD) to the gantry of the printer. I learned how to write G-code for 3D printers and researched how the firmware interpretted commands. I manually wrote G-code programs for the machine which glued up product components about 50% faster than their manual system.

With time to spare, I began the process of writing a postprocessor so that in the future Cofab could automatically generate programs for whatever product they needed glued. After completing the summer with a verbose technical report which documents the machine for non-technical stakeholders, Cofab now uses my device to run glue-ups on the official batches of one of their product components.

>> My team was asked by the Honda Research Institute to develop a system which autonomously charges your electric vehicle while you're away at work.

Half of the second semester was alloted for physical development, which I used to make a start on a physical prototype of the plug-guidance robotic arm. I set up the arm with ROS and Rviz, calibrated the cameras, gained experience with Gazebo, and gave Honda a system analysis program I programmed using Python.

On a team of four, I functioned as Systems & Robotics Engineer and Q2 Project Manager. More info about this project here.

>> In the summer of 2023 I built an electromechanical machine that automated the following task for Werfen, a leading biomedical company. My machine used real time, computer vision artificial intelligience to fill small sensor cards extremely precisely with a proprietary polymer solution. After filling, the machine turns on a UV light and cures the polymer solution. Werfen then uses these sensor cards for electrochemical blood analysis. My machine had a success rate of 75% compared to the original, manual system which had a success rate of 25%. The machine is currently being used by Werfen's research department.

>> In 8th grade I made an articulating robotic hand. It was 3D printed and controlled by an Arduino with potentiometers and servos. Initially it was supposed to be controlled via a glove equipped with flex sensors, but my homemade flex sensors (made from a cheap, conductive plastic material), weren't sensitive enough to control the hand. All in all, it was a difficult project and taught me a valuable lesson: to stick with a project even in the face of repeated failure.

>> As a freshman in college taking EGR 100, my team and I made a 1:50 scale, laser cut, passive solar house from chipboard and cellulose insulation. The outside door lets cool air in and hot air out if the inside becomes too hot. There‘s about a liter of water inside the house to act as a thermal mass. Through a combination of electrical design and heat transfer passive solar calculations, the inside temperature is kept within a degree of room temperature up to one hour after sundown in the middle of winter.

>> An electromagnetic listening device made with inductors and a simple amplifier. Holding the device up to electronics and some light bulbs produces a loud whirring noise. My favorite part was making those solder bridges.
