Design
Expedition

Some science, some art.

This is a showcase of my product design projects. I'm currently transitioning from a Mechanical Engineer to a Product Designer. I believe that this collection will grow the fastest.

Robot Puppeteering System

2020-

1/7

An ongoing human-robot interaction (HRI) project.

The user remotely manipulates a puppet of a robot to design expressive movements. Through video conferencing software, the user is able to review the actual robot motion in real-time. The designed motions in our user study are reviewed by a separate group of participants through an online survey.

The Raspberry Pi-based system achieved low latency.

Techniques/methods/technologies used:

Arduino programming
Raspberry Pi
Python programming
MQTT communication
Fast-prototyping
Research experiment design
Qualtrics survey design

Haptic
Balls-in-a-Box

2021

A haptic device simulating multiple objects rolling within. An Arduino Mega 2560 calculates the orientation of the box using accelerometer readings. The microcontroller then maps the positions of the balls to the vibration output of the motor array. The status of the balls can also be monitored through a graphic interface on Processing.

Techniques/methods used:

Fast prototyping
Haptic interfaces
C/C++ programming

Effects of Robot Secondary Actions

2021

This is a pilot study for my Human-Robot Interaction class during the 2021 Fall semester. We attempted to investigate whether an increased level of robot idle movements will improve a personal robot's approachability, animacy, and liveliness.

Techniques/methods used:

Human-robot interaction study design
User survey design
Python + Misty robot REST API

All Makers (Engineering
Start-up Concept)

2021

We all have heard stories of successful entrepreneurs, designers, and artists starting off their careers in garages. However, growing up in an urban apartment in a developing country, I never had such knowledge, budget, and space to "tinker around".

As a career goal, I hope to extend STEM education to more kids like me in emerging markets.

This slide deck was used for my final pitch for an imaginary company in my "How to Start and Grow a Hardware Company" class at Carnegie Mellon University.

Travelers'

First-Aid Kit

2021

A prototype made out of duck canvas, elastic bands, cardboard, and paper.

The idea is to get things organized and offer some customizability.

Below are excerpts of my presentation.

Techniques/methods used:

Six-hat technique
Market survey
Sketching
Mock-ups

Master Toaster

2020

A prototype of an ideal toaster.

Toasts consistently, no matter if your bread is frozen or not.

Reincarnation of temperature-monitoring toasters (using infrared sensors).

Due to the pandemic, we couldn't make our prototype more aesthetically pleasing, but you get the idea.

Techniques/methods used:

Brainstorming
Simulations
Kano analysis
Design for manufacturing and assembly
Rapid prototyping

Giant Eagle

Scan Pay & Go

Redesign

2020

The final project for the Human Factors class.

Redesigned user interface for the handheld scanner and mobile app. Additionally, I suggested that the weigh station print out labels for scanning and eliminate the log-in process. This reduces the risk of system errors and confusion.

Screw Extruder 3D Printer

2017-2018

An undergraduate research project at Bucknell University. Featuring a mini screw-based extruder, the system is the first desktop 3D printer capable of printing with plastic and composite pellets.
