'Flying Drones for Rescue'
(Video Credit: ⓒNASA JPL) < Team USRG and Professor Shim (second from the right) > Having recently won the AI R&D Grand Challenge Competition in Korea, Team USRG (Unmanned System Research Group) led by Professor Hyunchul Shim from the School of Electrical Engineering is all geared up to take on their next challenges: the ‘Defense Advanced Research Projects Agency Subterranean Challenge (DARPA SubT Challenge)’ and ‘Lockheed Martin’s AlphaPilot Challenge’ next month. Team USRG won the obstacle course race in the ‘2019 AI R&D Grand Challenge Competition’ on July 12. They managed to successfully dominate the challenging category of ‘control intelligence.’ Having to complete the obstacle course race solely using AI systems without any connection to the internet made it difficult for most of the eight participating teams to pass the third section of the race, and only Team USRG passed the long pipeline course during their attempt in the main event. They also demonstrated, after the main event, that their drone can navigate all of the checkpoints including landing on the “H” mark using deep learning. Their drone flew through polls and pipes, and escaped from windows and mazes against strong winds, amid cheers and groans from the crowd gathered at the Korea Exhibition Center (KINTEX) in Goyang, Korea. The team was awarded three million KRW in prize money, and received a research grant worth six hundred million KRW from the Ministry of Science and ICT (MSIT). “Being ranked first in the race for which we were never given a chance for a test flight means a lot to our team. Considering that we had no information on the exact size of the course in advance, this is a startling result,” said Professor Shim. “We will carry out further research with this funding, and compete once again with the improved AI and drone technology in the 2020 competition,” he added. The AI R&D Grand Challenge Competition, which was first started in 2017, has been designed to promote AI research and development and expand its application to addressing high-risk technical challenges with significant socio-economic impact. This year’s competition presented participants with a task where they had to develop AI software technology for drones to navigate themselves autonomously during complex disaster relief operations such as aid delivery. Each team participated in one of the four tracks of the competition, and their drones were evaluated based on the criteria for each track. The divisions were broken up into intelligent context-awareness, intelligent character recognition, auditory intelligence, and control intelligence. Team USRG’s technological prowess has been already well acclaimed among international peer groups. Teamed up with NASA JPL, Caltech, and MIT, they will compete in the subterranean mission during the ‘DARPA SubT Challenge’. Team CoSTAR, as its name stands for, is working together to build ‘Collaborative SubTerranean Autonomous Resilient Robots.’ Professor Shim emphasized the role KAIST plays in Team CoSTAR as a leader in drone technology. “I think when our drone technology will be added to our peers’ AI and robotics, Team CoSTAR will bring out unsurpassable synergy in completing the subterrestrial and planetary applications. I would like to follow the footprint of Hubo, the winning champion of the 2015 DARPA Robotics Challenge and even extend it to subterranean exploration,” he said. These next generation autonomous subsurface explorers are now all optimizing the physical AI robot systems developed by Team CoSTAR. They will test their systems in more realistic field environments August 15 through 22 in Pittsburgh, USA. They have already received funding from DARPA for participating. Team CoSTAR will compete in three consecutive yearly events starting this year, and the last event, planned for 2021, will put the team to the final test with courses that incorporate diverse challenges from all three events. Two million USD will be awarded to the winner after the final event, with additional prizes of up to 200,000 USD for self-funded teams. Team USRG also ranked third in the recent Hyundai Motor Company’s ‘Autonomous Vehicle Competition’ and another challenge is on the horizon: Lockheed Martin’s ‘AlphaPilot Challenge’. In this event, the teams will be flying their drones through a series of racing gates, trying to beat the best human pilot. The challenge is hosted by Lockheed Martin, the world’s largest military contractor and the maker of the famed F-22 and F-35 stealth fighters, with the goal of stimulating the development of autonomous drones. Team USRG was selected from out of more than 400 teams from around the world and is preparing for a series of races this fall, beginning from the end of August. Professor Shim said, “It is not easy to perform in a series of competitions in just a few months, but my students are smart, hardworking, and highly motivated. These events indeed demand a lot, but they really challenge the researchers to come up with technologies that work in the real world. This is the way robotics really should be.” (END)
Research Day Highlights Most Outstanding Research Achievements
Professor Byung Jin Cho from the School of Electrical Engineering was selected as the Grand Research Prize Winner in recognition of his innovative research achievement in the fields of nano electric and flexible energy devices during the 2019 KAIST Research Day ceremony held on April 23 at the Chung Kunmo Conference Hall. The ten most outstanding research achievements from the past year were also awarded in the three areas of Research, Innovation, Convergence Researches. Professor Cho is an internationally recognized researcher in the field of future nano and energy device technology. Professor Cho’s team has continued to research on advanced CMOS (complementary metal-oxide semiconductors). CMOS has become his key research topic over the past three decades. In 2014, he developed a glass fabric-based thermoelectric generator, which is extremely light and flexible and produces electricity from the heat of the human body. It is so flexible that the allowable bending radius of the generator is as low as 20 mm. There are no changes in performance even if the generator bends upward and downward for up to 120 cycles. His wearable thermoelectric generator was selected as one of the top ten most promising digital technologies by the Netexplo Forum in 2015. He now is working on high-performance and ultra-flexible CMOS IC for biomedical applications, expanding his scope to thermal haptic technology in VR using graphene-CMOS hybrid integrated circuits; to self-powered wireless sensor nodes and self-powered ECG system using wearable thermoelectric generators . In his special lecture at the ceremony, Professor Cho stressed the importance of collaboration in making scientific research and presented how he moved to future devices after focusing on scaling the devices. “When I started the research on semiconductors, I focused on how to scale the device down as much as possible. For decades, we have conducted a number of procedures to produce tiny but efficient materials. Now we have shifted to develop flexible thermoelements and wearable devices,” said Professor Cho. “We all thought the scaling down is the only way to create value-added technological breakthroughs. Now, the devices have been scaled down to 7nm and will go down to 5 nm soon. Over the past few years, I think we have gone through all the possible technological breakthroughs for reducing the size to 5nm. The semiconductor devices are made of more 1 billion transistors and go through 1,000 technological processes. So, there won’t be any possible way for a single genius to make a huge breakthrough. Without collaboration with others, it is nearly impossible to make any new technological breakthroughs.” Professor Cho has published more than 240 papers in renowned academic journals and presented more than 300 papers at academic conferences. He has also registered approximately 50 patents in the field of semiconductor device technology.

Samsung Electronics' Chairman Kwon Becomes the First Alumnus Honorary Doctorate
(Samsung Electronics' Chairman & CEO Kwon,left, and President Shin) The semiconductor has bred innovation in Korea, as one of the staples of economic growth. Without the success of the semiconductor industry of Korea, it is hard to imagine the high tech dominance in the global market enjoyed by Korean companies. It is said that one in every four Ph.D.s working in the semiconductor industry of Korea graduated from KAIST. Among them, Chairman and CEO Oh-Hyun Kwon of Samsung Electronics, Class of 1977, has arrived at the epitome of this top industry. KAIST’s class of 1977 produced many movers and shakers in Korea’s innovation efforts. Now in their mid-60s, they were the players who embodied Korea’s ICT and helped it become a global powerhouse. They are the ones who worked for and witnessed the socio-economic transformation of Korea through innovation. In recognition of his unsurpassable entrepreneurship, which made the remarkable strides in the semiconductor and electronics industry in Korea and beyond, Chairman Kwon was honored as the first recipient of an honorary doctorate from his alma mater on February 23 during the 2018 commencement ceremony. After completing his Master's in Electrical Engineering at KAIST in 1977, he earned his Ph.D. in Electrical Engineering from Stanford University. The first honorary degree bestowed to an alumnus was conferred by the first alumnus President of KAIST Sung-Chul Shin. President Shin said that Chairman Kwon’s exceptional leadership has inspired the KAIST community and exemplified the spirit of KAIST. Currently serving as chairman & CEO of Samsung Electronics and Samsung Advanced Institute of Technology (SAIT), Kwon has worked for Samsung in a variety of key positions in their semiconductor division since 1985. In the mid-1980s, Japan was leading the global semiconductor market. At Samsung, Chairman Kwon, who was in charge of the memory semiconductor team, successfully developed 4M DRAM. Later in 1992, he played a leading role in the development of the world’s first 64M DRAM. The success of 4M DRAM and 64M DRAM led Samsung to clinch the top position in the DRAM and NAND flash business around the world. This helped Samsung emerge as a global leader in the semiconductor industry. As a result, Samsung, as well as the national economy, could gain significant momentum to build national competitiveness and economic growth. The outstanding technological leadership of Chairman Kwon led to the development of proprietary semiconductor design and processes technologies as well as numerous patents. He also played a leadership role in creating a mutual growth environment among conglomerates rather than merely engaging in direct competition. Chairman Kwon made every effort to establish the cornerstone of mutual growth, especially in relationships with small and medium-sized enterprises (SMEs). His win-win collaboration initiatives among conglomerates and SMEs made a significant impact on the development of the entire industry of Korea. In his acceptance speech, he charged the graduates to embrace challenges, to collaborate with peers, and create their own future. The full text of his speech is printed below. Graduates and distinguished guests! I extend my sincere congratulations to my fellow graduates, as you are awarded degrees for your deep efforts, as well as to the parents and family members who have supported you. In 1977, I received my Master’s degree in Electrical Engineering from KAIST. Today, as the first honorary doctor among KAIST graduates, I am truly honored to be here. I am deeply grateful to all of you, including President Sung-Chul Shin and the Chairman of the Board of Trustees, Jang-Moo Lee. Today, I want to tell you about the experiences and lessons I have learned from my 40 years of corporate management experience. First, you should lead and drive changes by yourself. In the process of realizing a dream, the situation and circumstances do not always proceed as you planned. I started my career as a researcher. However, I had to continuously transform myself into a project leader, business team leader, and CEO. It was challenging every time, due to a lack of preparing and my insufficient ability. However, I have always accomplished the intended goal through the mindset of embracing changes and studying new things. It is said that the survivors are not always the strongest nor the most intelligent, but the ones who are the most adaptive to changes. We can only be the last survivor if we have the character to see those small signs that signal changes are coming and cope with changes well. Take changes positively and actively and then, transform yourself to match a given situation. In addition, it is important to understand others. When it comes to one’s career, there is nothing that you can do alone without the assistance of others. If it is not possible to do everything by yourself, you will need to supplement your efforts through the help of others. To do this, you need to understand your colleagues, bosses, and customers first. People, who work in tech tend to cage themselves in their own silos. But in an era of destructive innovation, where boundaries of industries and technologies are collapsing at a breakneck pace, scientists also need to enhance their understanding of various areas such as culture, art, and the humanities. This is a famous verse from a poem by Chun-Soo Kim. Before I called his name, He was nothing but a gesture. When I called his name, He came to me and became a flower. Make wonderful synergy by making your partner a flower and complementing each other. When you first notice the true value of another person and interact with them, the value of the individual will be doubled and will bring about a greater impact. Finally, we all need to cooperate with each other. All of you here, including myself, are people who have benefited from society. We must cooperate with each other and give back to society for the best results. A biologist once said that incremental evolution comes from competition, but fundamental evolution comes from cooperation. Great leaders should achieve results through cooperation rather than competition. You are the future leaders with top-class knowledge. I hope you will become great leaders who have wisdom that combines external resources with your abilities. Now, graduates of 2018 who are standing at the starting line, we often worry about an unpredictable tomorrow. However, the smartest way to predict the future is to create the future for ourselves. Moreover, we can try again even though we sometimes make mistakes. I urge you to make future you are hoping for. Once again, I would like to thank you for this honorary doctorate and extend my sincere wishes for the endless development of KAIST and the best of luck to the futures of these graduates. Thank you.
Soul-Searching & Odds-Defying Determination: A Commencement Story of Dr. Tae-Hyun Oh
(Dr. Tae-Hyun Oh, one of the 2736 graduates of the 2018) Each and every one of the 2,736 graduates has come a long way to the 2018 Commencement. Tae-Hyun Oh, who just started his new research career at MIT after completing his Ph.D. at KAIST, is no exception. Unlike the most KAIST freshmen straight out of the ingenious science academies of Korea, he is among the many who endured very challenging and turbulent adolescent years. Buffeted by family instability and struggling during his time at school, he saw himself trapped by seemingly impenetrable barriers. His mother, who hated to see his struggling, advised him to take a break to reflect on who he is and what he wanted to do. After dropping out of high school in his first year, ways to make money and support his family occupied his thoughts. He took on odd jobs from a car body shop to a gas station, but the real world was very tough and sometimes even cruel to the high school dropout. Bias and prejudice stigmatizing dropouts hurt him so much. He often overheard a parent who dropped by the body shop that he worked in saying, “If you do not study hard, you will end up like this guy.” Hearing such things terrified him and awoke his sense of purpose. So he decided to do something meaningful and be a better man than he was. “I didn’t like the person I was growing up to become. I needed to find myself and get away from the place I was growing up. It was my adventure and it was the best decision I ever made,” says Oh. After completing his high school diploma national certificate, he planned to apply to an engineering college. On his second try, he gained admission into the Department of Electrical Engineering at Kwang Woon University with a full scholarship. He was so thrilled for this opportunity and hoped he could do well at college. Signal processing and image processing became the interest of his research and he finished his undergraduate degree summa cum laude. Gaining confidence in his studies, he searched around graduate school department websites in Korea to select the path he was interested in. Among others, the Robotics and Computer Vision Lab of Professor In-So Kweon at the Department of Electrical Engineering at KAIST was attractive to him. Professor Kweon’s lab is globally renowned for robot vision technology. Their technologies were applied into HUBO, the KAIST-developed bimodal humanoid robot that won the 2015 DARPA Challenges. “I am so appreciate of Professor Kweon, who accepted and guided me,” he said. Under Professor Kweon’s advising, he could finish his Master’s and Ph.D. courses in seven years. The mathematical modeling on fundamental computer algorithms became his main research topic. While at KAIST, his academic research has blossomed. He won a total of 13 research prizes sponsored by corporations at home and abroad such as Kolon, Samsung, Hyundai Motors, and Qualcomm. In 2015, he won the Microsoft Research Asia Fellowship as the sole Korean among 13 Ph.D. candidates in the Asian region. With the MSRA fellowship, he could intern at the MS Research Beijing Office for half a year and then in Redmond, Washington in the US. “Professor Kweon’s lab filled me up with knowledge. Whenever I presented our team’s paper at an international conference, I was amazed by the strong interest shown by foreign experts, researchers, and professors. Their strong support and interest encouraged me a lot. I was fully charged with the belief that I could go abroad and explore more opportunities,” he said. Dr. Oh, who completed his dissertation last fall, now works at the Department of Electrical Engineering and Computer Science at MIT under Professor Wojciech Matusik. “I think the research environment at KAIST is on par with MIT. I have very rich resources for my studies and research at both schools, but at MIT the working culture is a little different and it remains a big challenge for me. I am still not familiar with collaborative work with colleagues from very diverse backgrounds and countries, and to persuade them and communicate with them is very tough. But I think I am getting better and better,” he said. Oh, who is an avid computer game player as well, said life seems to be a game. The level of the game will be upgraded to the next level after something is accomplished. He feels great joy when he is moving up and he believes such diverse experiences have helped him become a better person day by day. Once he identified what gave him a strong sense of purpose, he wasn’t stressed out by his studies any more. He was so excited to be able to follow his passion and is ready for the next challenge.
First Female Grand Prize Awardee of Samsung Humantech
Yeunhee Huh, PhD candidate (Professor Gyu-Hyeong Cho) from the School of Electrical Engineering received the grand prize of the 24th Humantech Paper Award. She is the first female recipient of this prize since its establishment in 1994. The Humantech Paper Award is hosted by Samsung Electronics and sponsored by the Ministry of Science and ICT with JoongAng Daily Newspaper. Her paper is titled, ‘A Hybrid Structure Dual-Path Step-Down Converter with 96.2％ Peak Efficiency using 250mΩ Large-DCR Inductor’. Electronic devices require numerous chips and have a power converter to supply energy adequately. She proposed a new structure to enhance energy efficiency by combining inductors and capacitors. Enhancing energy efficiency can reduce energy loss, which prolongs battery hours and solves overheating of devices; for instance, energy loss leads to the overheating issue affecting phone chargers. This technology can be applied to various electronic devices, such as cell phones, laptops, and drones. Huh said, “Power has to go up in order to meet customers’ needs; however the overheating problem emerges during this process. This problem affects surrounding circuits and causes other issues, such as malfunctions of electronic devices. This technology may vary according to the conditions, but it can enhance energy efficiency up to 4%.”During the ceremony, about eight hundred million KRW worth cash prizes was conferred to 119 papers. KAIST (44 papers) and Gyeonggi Science High School (6 papers) received special awards given to the schools.
Professor Hojong Chang Wins the Best Paper Award at ISIITA 2018
Professor Hojong Chang from the KAIST Institute won the best paper award at the International Symposium on Innovation in Information Technology and Application (ISIITA) 2018. ISIITA is a global networking symposium in which leading researchers in the field of information technology and applications gather to exchange knowledge on technological convergence. Professor Chang won the prize for his paper, titled ‘A Study on the Measurement of Aptamer in Urine Using SiPM’. This paper proposes using aptamer to measure and analyze the density of sodium and potassium contained in urine, allowing diseases to be diagnosed in advance. Professor Chang said, “With a point-of-care test system that facilitates a quick diagnosis without extra processes, such as centrifugation, it is possible to get an early diagnosis and check infection in real time. Through generalizing this crucial technology, we expect to develop adequate technology for enhancing quality of life.
