In 2010, a team of graduate students from Philosophy, Design, Electrical Engineering, and Mechanical Engineering worked together to design a home service robot of the future. We initially started with using the Taguchi method, a robust hardware design method, to list the necessary functions of the future robot. Subsequently, we had regular ideation/brainstorming sessions iteratively to come up with future robots that will operate in an automated household environment.
"Multi-scale mass-deployable cooperative robots are a next-generation robotics paradigm where a large number of robots that vary in size cooperate in a hierarchical fashion to collect information in various environments. While this paradigm can exhibit the effective solution for exploration of the wide area consisting of various types of terrain, its technical maturity is still in its infant stage and many technical hurdles should be resolved to realize this paradigm." (Choo et al., 2013)
The Cycle Atlanta project aims at creating sensor systems that allow a bike to "see" its environment and collect data as a participatory effort so that we can help the City of Atlanta to make informed decisions about biking infrastructures. Specifically, a sensor box equipped with sonars, lidars, PM sensors, gas sensors, gyroscope, accelerometer, and others was developed to detect environmental factors that can give rise to cyclists' stress level. I participated in this project as a Data Science for Social Good (Atlanta's DSSG) Summer fellow in 2017.
This project was my final team project for "Electrical Engineering Laboratory 3" class in 2004 (when I was junior in college). The goal was to make a wireless system that substitutes price tags with electrical displays in grocery stores. The base station manages a list of products in the database, and it sends out price information to receiver units. Receiver units are simple character displays having unique IDs. When any products' prices change, the system can easily update new prices on these displays.
This prototype was an intermediate result of a robot-human interaction project conducted at Torooc Inc., a VC-funded start-up company where I was a co-founder and Director of Software Development, in 2011. We started up this company through winning the first-place prize at the 2012 Start-up Competition by Seoul National University R&DB Foundation and Seoul Techno Holdings.
