EGGY,Your healing friend
About EGGY
EGGY is a social robot that relieves daily stress through communication with users. The meaning of the name EGGY is derived from βeggβ of eggs and βμ κΈ°β which means baby in Korean. When you stroke EGGY, you look around and smile when you find a user. EGGY, which shows a variety of expressions as you pet it, will come as small happiness in your daily life to users who are tired of life.

Due to the COVID situation that spread around the world in 2020, many people are unwantedly distancing themselves from others, leading to the social phenomenon called βCOVID Blueβ due to increased depression. Methods to relieve this COVID depression include participation in regular meetings with others, communication with companion animals, and drug prescriptions, but the reality is that many people are not in good conditions in the COVID situation.

EGGY was designed for people who have difficulty meeting with others and cannot afford to raise companion animals. By providing an experience of interacting with pets through βpatting,β one of the ways to interact with them, we will relieve the stress of the lack of encounters in daily life due to the COVID-19 incident.

There were three functions necessary for EGGY to communicate with users: eye contact, response to touch, and facial expression. To implement these functions, we tested the ability to follow a personβs face using raspberry pies, cameras, servo motors, acceleration sensors, output faces on display, and recognize petting.

To give a more natural stroking feeling, I made egg-shaped prototypes with a height of 14-18cm and a maximum diameter of 13-16cm. By using the prototypes, I investigated the satisfaction of the stroking feeling for each model. As a result of the survey, feedback was dominant that egg-shaped prototypes with a height of 16cm and a maximum diameter of 14cm had the

highest satisfaction. In the case of prototypes made 18cm height by increasing only the same type of ratio, satisfaction was lower than the small prototype.

Multiple parts like LCD displays and sensors were used to facilitate interactions like moving along people and expressing facial expressions. The parts were carefully placed, not to disturb the movement of Egg, and coupling and driving tests were performed. In the case of LCD screens, since they are arranged at the top rather than the bottom where motors, raspberry pies, servo modules, etc. are arranged, a structure was needed to operate smoothly without twisting the wiring. As a result of testing various structures for this structure, we were able to complete a structure in which the pie camera line naturally connects without interfering with driving.

During the COVID situation, most people suffered from disconnection. I was also one who suffered from disconnection with family and friends. At the early moment of the COVID situation, honestly, I hadnβt suffered a lot. As time went by, I knew I was wrong. Disconnection with many people made people more sensitive, and stressed, not only about me but also about family and friends. So, I wanted to make a product that can release daily stress from the COVID situation.
Initially, I tried to make a product without electronic components. However, thanks to Kyungho Lee, my thankful advisor, I learned the importance of interaction between product and user. There were many challenges to making Eggy, especially for technical reasons. But by solving those problems, I felt I grew up. This feeling of accomplishment made me keep working on my project for nearly eight months.
I think Creative Design is not the closing project in UNIST. Itβs last chance to design what I want to design. In Creative Design, there is no topic or restriction. This is first, and last chance to design what you want to try. In my case, I tried totally new technology that Iβve never knew. Of course it was hard and I made many mistakes, but through that process, I think I expand my field of design.
How did you come up with the idea of your project?
How could you work on your project for a long time?
Any advice for future students of Creative Design 1 and 2?

During the courses till junior, there was no exhibition. That means I donβt need to show my product to a normal audience. In the exhibition, I need to think not only about the product itself. I also need to think about how to show the product. This helped me to think more about usability and sturdiness. In the normal course, usually, the professor is only a user to interact with my product, but in the exhibition, more than ten people are trying to interact with my product.
Because I focused on detail structure too much, I took too much time in designing the internal structures. I used bolts to achieve both sturdiness and maintenance, but it required me too much time. Also, I used 3D printing as a major prototyping method, but it made me wait too much time for each trial. If I can turn back time, Iβd like to use CNC as a major prototyping method of my project.
Thank all faculty members in UNIST, especially in the design department. Also, special thanks to professor Kyungho Lee, who lead me from the start to the end of the project, and professor Youngwoo Park, who managed Creative Design course. And thank you to all EXPC Lab members and teacher Gichul Yook, who helped solve problems and cheered me when I go through a hard time.
How did you grow as a designer by doing this exhibition?
If you cold turn back time, what advice would you give yourself?
Anything else you want to say to anyone?
