XactSense CAD Consultant

Duration: January 2015-Current

Team Size: Individual

During the winter break of my junior year, I worked as a consultant for XactSense. XactSense is

a robotics startup based out of Providence, RI developing a robust, GPS-less quadcopter for

terrain mapping. I worked as a consultant for the team, which included producing CAD models

in SolidWorks of the entire system and aiding in design the LIDAR gimbal (seen above).

1:240 Gearbox Project

Duration: October 2014-December 2014

Team Size: 3 students

The objective of this project was to conceptualize, design, and model a gearbox for ME359:

Introduction to CAD and Machine Components. The gearbox had to be manufacturable and

have a gear ratio of 1/240. The design and CAD models were created in PTC Creo. I was the

team leader and responsible for designing and modeling the axles as well as making sure the

team worked efficiently and the final project met all requirements.

Dean Lutchen Fellowship

Duration: Summer 2014

I spent the summer of 2014 working in the Engineering Production Innovation Center (EPIC) at

Boston University under the Dean Lutchen Fellowship. During the 10 week span, I performed

research in the Automated Design and Manufacturing Lab. In this lab I learned how to operate

a multi-level educational robotic assembly line. I also learned about ceramic 3D printing. This

involved using a retrofitted ZCorp Spectrum z510 printer to test material strength and

properties of different ceramic compositions. More information on the Fellowship and my

experience can be found at http://www.bu.edu/eng/lutchen/.

Low Cost Centrifuge

Duration: March-May 2014 Team Size: 4 students Over the course of the semester, my team designed and built a low cost centrifuge for a client at the Boston University School of Medicine. The centrifuge was built with a budget of $400 in a 12-week time span. The majority of the work was performed in the Engineering Product Innovation Center (EPIC) at Boston University. I was responsible for the electronics and client relations. This involved visiting the client at the medical campus and establishing objectives and metrics that needed to be accomplished.

Research Experience for Undergraduates

at Johns Hopkins University

Duration: Summer 2013

Participated in the R.E.U. program at the Laboratory for Computation Sensing and Robotics at

Johns Hopkins Whiting School of Engineering. I spent the summer developing an aerial robotic

vehicle that could safely operate in crowded or cluttered environments. This was accomplished

by designing multiple bumper system prototypes. The final revision was a balloon-type

inflatable ring built out of a thin Mylar material. I also learned how to program in Linux and

Smart Medicine Cabinet

Duration: Spring 2013

Team Size: Individual

In the spring of my freshmen year, I built a “Smart Medicine Cabinet” for B.U.’s annual Imagineer Lab

Contest. My Smart Medicine Cabinet combined a medicine cabinet with numerous electronics and

internet connectivity in the hopes of making prescription management easier. It also contained large

color-coded displays that showed the user when and how many pills to take. A third feature was a

finger scanner–locking mechanism to prevent prescription drug abuse. This project placed 3rd out of 26

High School Projects

(1) (2)

1) Built a 2 digit 7-segment LED scoreboard using the VEX microcontroller.

Project was featured on the cover of “Nuts and Volts” April 2010 edition.

2) Built a Whiteboard Erasing Robot. Robot was able to autonomously erase text

on a classroom whiteboard using computer vision software.
