Acoustic Focusing for Non-Contact Assembly of Composites in Manufacturing
Development and Applications of Acoustic Focusing for Particle Assembly
2024 PhD Thesis (DSpace Link)
Acoustic focusing is a non-contact method for assembling sub-mm particles to create designed composites. In this work, I discuss how acoustic focusing fits in the manufacturing ecosystem of extruded composites and the challenge of balancing assembly precision with speed. I developed strategies for improving assembly speed while bypassing maximum acoustic transducer power limitations.
Precision Origami Folding
Origami Structure for 2D+ Assembly
September 2013 - August 2015
2015 MSc Thesis (DSpace Link)
Origami structures may be combined with precision 2D assembly methods to enable 2D+ assembly of 3D cell structures. This work explains how to design the structure and its constraints to minimize misalignment errors during folding.
Artery Phantom for Medical Ultrasound
Phantom for validating Medical Ultrasound Blood Pressure Measurements
June 2011 - May 2012
BSc Thesis (DSpace link)
Ultrasound is a benign alternative to cuffs for measuring blood pressure. To validate ultrasound as a blood pressure measurement technique, I designed, prototyped and tested a mechanical phantom that mimicked the mechanical properties of the brachial artery during static and dynamic artery flow.
Solar Car Hub and Spindle
Desktop Lathe
System Model of Linear Stage Friction
Design/Build Hub and Spindle for Solar Car
October 2011 - May 2012
Project report: PDF link
Design of the wheel hub and spindle of a solar car for the MIT Solar Car Team. The parts were designed to survive multiple races each exceeding 2000 km. The spindle and hub were designed/produced and successfully integrated into Solar Car for the 2012 American Solar Challenge.
Design/Model/Build of Desktop Lathe
February - May 2012
This project was to design and then manufacture a desktop lathe capable of turning aluminum. The lathe also had to survive 1) a fall from ~ a 3-foot height, 2) a hit with a sledgehammer, and 3) ~ a 120-lb static load on the bed.
Dynamic Model of Linear Stage undergoing oscillating motion.
November 2018
Dynamic model of linear stage under stop-go motion. Key challenge was to model stiction and kinetic friction alongside the electrical and mechanical components.
Instrumentation/Control
Vibration Isolation of Speaker
Feedback Control Design for Vibration Isolation of Speaker
November 2021
Design/Construction of Feedback Controller to isolate speaker cone from vibrations. The controller system comprises the speaker, filter circuit, LabVIEW controller, and MyRIO interface.
Design/Build of Microcomputer to Control Desktop Lathe
Design/Build of Microcomputer to Control Desktop Lathe
April 2012
Design/Construction of microcomputer to power and control (open-loop) the spindle motor and motors driving the 2-axis bed of a Desktop Lathe.
Force Resistive Sensor Construction
Resistive Sensor Assembly with Vernier Environment
2020-2023
Designed and constructed circuits integrating resistive sensors with the Vernier Data Collection Environment. Sensors used to collect data in projects for the Measurement and Instrumentation Class at MIT.
Betty - Aquatic Search Robot
Develop/Deploy Autonomous Robot
February - May 2011
Equip and program an aquatic vehicle (Kingfisher M100) to autonomously search for beacons in Charles River
Boxfish - Underwater ROV
Design/Build Underwater ROV
February - May 2009
Design/Build/Deploy underwater ROV
Shop Skills, Design for Manufacturing
Volume Manufacturing - CNC Design of Injection Molding /Thermoforming Molds
CNC Design of Injection Molding, Thermoforming Molds
February - May 2011
Design/Production of molds for injection molding and thermoforming as part of the Design for Manufacturing Class. Molds were CNC machined on mill and lathe (Mastercam)
CNC Paperweight
Aluminum Paperweight - CNC
February 2011
CNC machining of Aluminum paperweight. Profile was turned on the CNC lathe. The image of the Hyrule crest was CNC milled. CNC programs were created in Mastercam.
TIG Welded Car Chassis
Solar Car Chassis - TIG Welding
June - August 2010
TIG welding the roll cage and car chassis for a Solar Car. The chassis and roll cage were made of steel tubing — chassis design by Mike Roberts. The car was road-tested in the Summer of 2011 and raced in the 2011 World Solar Challenge.
Machined Aluminum Flashlight - Mill, Lathe
Aluminum Flashlight - Mill, Lathe
Fall 2008
Constructed as part of lathe and mill training, MIT Edgerton Student Shop, 2008
Archery
Fence for Outdoor Archery Practice at MIT
Briggs Field Fence - MIT Archery Team Practice
2024 - Designed and built to protect onlookers during archery practice on the mixed-use field at MIT. The fence is 400 feet long and designed to be assembled and disassembled for each practice. This is the only outdoor archery range within 10 miles of central Boston.
Arrow Building
Arrow Building
I build my arrows for practice and tournaments, from cutting the shafts to fletching and point installation. Outdoor arrows are carbon-wrapped aluminum shafts, fletched with vanes. Indoor arrows are aluminum, fletched with feathers.
Bow Maintainance
Tuning, nock tying and wrapping the center serving on bow string.
