Spring 2019 / COS 333: Advanced Programming Techniques

TigerMeet is a web application that enables Princeton University students to connect with other students for recreation, transportation, and academic coordination. It is divided into sections of general interest (i.e. Sports, Transportation) each with a general chat as well as the ability to create specific events with chatrooms for users to connect.

Spring 2018 / MAE 322: Mechanical Design

Our team was tasked with designing, fabricating, and testing a Search and Rescue Robot (SaRR) that will simulate real-life search and rescue operations by performing the following tasks:

Retrieve a simulated medical kit weighing 2.5 lbs
Quickly drive to and around a pylon placed about 50’ away
Autonomously breach a 12” tall stair-step obstacle
Autonomously navigate a twisting chute without contacting walls
Autonomously sense and drive toward a light source
Autonomously place the simulated medical kit into a basket at the light source

Spring 2018 / MAE 342: Space System Design

Interdisciplinary Mission for Imaging Satellites and SpacE Debris (I-MISSED)

The primary goal of I-MISSED is the design of a 6U sized cubesat that can be launched into GEO for the imaging of a subject satellite, GOES-T, on schedule to launch in 2020. This follower cubesat can perform on-station, on-demand visual imaging of the multi-billion dollar subject satellite, providing operating information on mechanism deployments and damage assessments after potential collision events. A secondary objective will be performing basic space debris analysis that can provide feedback on potential impacts.

Fall 2017 / MAE 321: Engineering Design

The goal of this project is to design a lightweight structure (crane) of minimum weight that could lift at least 260 pounds. The structure is constrained by a $250 budget for materials and overall shape dimensions. Removing material in optimized areas decreased total weight and incorporating different aluminum grades supported areas under greater or lower stresses for the lowest weight. The crane was machined and tested with a pulley device.

Final Report

Jun-Aug 2017

Developed a computer vision program with MATLAB to track and model the 3D structure of dynamic artificial caudal fins with a single camera for bio-inspired propulsion research.
