Team USRG’s Winning Streak Continues at the AI Grand Challenge
Team USRG (Unmanned Systems Research Group) led by Professor Hyunchul Shim from the School of Electrical Engineering has won the AI Grand Challenge 2020 held on Nov. 23 at Kintex in Ilsan, Kyonggi-do for the second consecutive year. The team received 7.7 million KRW in research funding from the Ministry of Science and ICT, the organizer of the challenge. The team took a little over two minutes to complete the rescue operation mission of the challenge. The mission included swerving around seven obstacles, airdropping an aid package, and safely landing after identifying the landing spot. Their drone is the only one that successfully passed through a 10-meter tunnel out of five pre-qualified teams: three from universities and two from companies. The AI Grand Challenge, which began in 2017, was designed to promote AI technology and its applications for addressing high-risk technical challenges, especially for conducting complex disaster relief operations. For autonomous flying drones, swerving to avoid objects has always been an essential skill and a big challenge. For their flawless performance in the rescue operation, the team loaded an AI algorithm and upgraded their drone by improving the LiDAR-based localization system and a stronger propulsion system to carry more sensors. The drone weighs 2.4 kg and carries a small yet powerful computer with a GPU. This AI-powered drone can complete rescue missions more efficiently in complicated and disastrous environments by precisely comprehending where the drone should go without needing GPS. The team also designed an all-in-one prop guard and installed a gripper onto the bottom of the drone to hold the aid package securely. “We tried hard to improve our localization system better to resolve issues we had in the previous event,” said Professor Shim. Two PhD candidates, Han-Sob Lee and Bo-Sung Kim played a critical role in developing this drone. After their two-year winning streak, their prize money now totals 2.4 billion KRW, equivalent to the winning prize of the DARPA Challenge. As the winning team, they will collaborate with other champions at the AI track challenge to develop rescue mission technology for a more complex environment. “The importance of AI technology is continuing to grow and the government is providing large amounts of funding for research in this field. We would like to develop very competitive technology that will work in the real world,” Professor Shim added. His group is investigating a wide array of AI technologies applicable to unmanned vehicles including indoor flying drones, self-driving cars, delivery robots, and a tram that circles the campus.

Wall Climbing Quadcopter by KAIST Urban Robotics Lab
Popular Science, an American monthly magazine devoted to general readers of science and technology, published “Watch This Creepy Drone Climb A Wall” online describing a drone that can fly and climb walls on March 19, 2015. The drone is the product of research conducted by Professor Hyun Myung of the Department of Civil and Environmental Engineering at KAIST. The flying quadcopters can turn into wall-crawling robots, or vice versa, when carrying out such assignments as cleaning windows or inspecting a building’s infrastructure. Professor Myung leads the KAIST Urban Robotics Lab (http://urobot.kaist.ac.kr/). For a link to the article, see http://www.popsci.com/watch-drone-climb-wall-video. Another Popular Science article (posted on April 3, 2015), entitled “South Korea Gets Ready for Drone-on-Drone Warfare with North Korea,” describes a combat system of drones against hostile drones. Professor Hyunchul Shim of the Aerospace Engineering Department at KAIST developed the anti-drone system. He currently heads the Unmanned System Research Group, FDCL, http://unmanned.kaist.ac.kr/) and the Center of Field Robotics for Innovation, Exploration, aNd Defense (C-FRIEND).

Professor Shim Featured with His Drone System in IEEE Spectrum
The IEEE Spectrum, a technology and science magazine published by the Institute of Electrical and Electronics Engineers (IEEE), featured an article of KAIST’s autonomous unmanned aerial vehicles (UAVs) entitled “South Korea Prepares for Drone vs. Drone Combat,” posted on April 1, 2015. The article introduces the anti-drone defense system being developed by Professor “David” Hyunchul Shim of the Department of Aerospace Engineering at KAIST. With the goal of developing guard drones that can detect and capture unknown UAVs, the anti-drone defense system consists of reconnaissance drones, agile multi-rotor UAVs equipped with nets which are dropped to snare enemy drones, and transport UAVs to carry smaller drones. Professor Shim currently leads KAIST’s Unmanned System Research Group (USRG, http://unmanned.kaist.ac.kr/) and Center of Field Robotics for Innovation, Exploration, aNd Defense (C-FRIEND).

Strawberries Delivered by A Miniature Drone at KAIST Spring Festival
The "HAPPY KAIST 2014 Spring Festival" held at KAIST from 4th April The Cherry Blossoms Festival under the theme of "Cherry Blossoms: Light and Fantasy" held on 4th April The Strawberry Party with strawberries exclusively delivered by a miniature drone on 11th April KAIST is holding a spring festival from April 4th through 11th. As a part of the "HAPPY KAIST 2014" event, cherry blossoms festival and strawberry party will be held at KAIST campus starting on April 4th. This event has been organized with the purpose of creating a new culture and tradition for members of KAIST to unite. Faculty members, staff, and students have all contributed to making the festival a success. The cherry blossoms festival, held under the theme of "Cherry Blossoms: Light and Fantasy," takes place at the road in front of the KAIST north dormitory, which provides a spectacular view of cherry blossom trees. It begins on the night of April 4th and continues until the 8th of April. Around the cherry blossom tree road displays an art exhibition by the Design Rangers, a student club of graduate and doctorate students from the Department of Industrial Design at KAIST. The exhibition includes the "Fantasy Cherry Blossoms" and "Let’s Walk Together." Following on the 11th will be the "Strawberry Party" to take place throughout the campus. The strawberry party began in 1995 in order to help the local strawberry farmers. Now, it has become KAIST’s own unique tradition attended by faculty, student clubs, and laboratory members. This year, the fruit party becomes a unique event in that there will be a demonstration of strawberry delivery by an unmanned vehicle or an unmanned aerial vehicle (a miniature drone). When a customer orders strawberries via a smart phone application, the user's current location is sent to the central system of an unmanned vehicle. Either the unmanned vehicle (UV) transports strawberries or for places inaccessible by the UV such as on a lawn, the drone delivers the fruit to the customer . This demonstration has been organized by Professor Hyunchul Shim from the Department of Aerospace Engineering at KAIST. Professor Shim said, “If the unmanned logistics system, such as the one being demonstrated at the Strawberry Party, is commercialized, both cost and time in the logistics industry can be significantly reduced.” The HAPPY KAIST 2014, organized by the College of Engineering, is an annual event, consisting of a total of five programs, with the purpose to make the campus happier and healthier.

When Technology Meets Spring: A Drone Delivering Strawberries Greets the Change of Seasons in KAIST
KAIST celebrates the arrival of spring by hosting a variety of cultural events for university members as well as the surrounding community members. The "Happy KAIST 2014" will be held from April 4 to April 11th, which includes the “Cherry Blossoms Festival” and “Strawberry Party.” The event is free and open to the public. As part of the strawberry party, visitors to the campus can order the fruit to be delivered to the place where they sit via a drone developed by Professor Hyunchul Shim of Aerospace Engineering at KAIST. The strawberry delivery by a drone starts on April 11. Throughout the campus, the drone will deliver up to 100 containers of strawberries to customers.
