< Photo 1. WalkON Suit F1 - walking demonstration >
KAIST researchers have unveiled a new wearable robot developed for completely paralyzed persons that can walk to them so that the user can wear it right out of their wheelchairs without the help from others. Also, it was announced that Professor Kyoungchul Kong's team from KAIST will be participating in the wearable robot category of the 3rd Cybathlon, which is being held four years after the team’s gold medal win in 2020.
KAIST (President Kwang-Hyung Lee) announced this new version of the wearable robot for paraplegic people, WalkON Suit F1, by Professor Kyoungchul Kong (CEO and founder of Angel Robotics) of KAIST Department of Mechanical Engineering on the 24th of October.

WalkON Suit is a wearable robot for people suffering with paraplegic disabilities that the research team has been continuously researching since 2015. This robot targets to assist persons with American Spinal Injury Association (ASIA) Impairment Scale – A (complete paralysis) grade injury, the most severe level of paraplegia. Therefore, its development purpose is different from that of other rehabilitation therapy and muscle strength assisting robots currently being supplied nationally by Angel Robotics.
Professor Kong's research team first announced WalkON Suit 1 in 2016, and then introduced WalkON Suit 4 in 2020, increasing the walking speed to 3.2 km/h, achieving the normal walking speed of people with no disabilities. In addition, it demonstrated the ability to pass through obstacles such as narrow passages, doors, and stairs that can be encountered in daily life.
However, it had the same fundamental problem all wearable robots have, which is that they require the help of others to wear the robot. While you can walk without help from others once you are wearing the robot, you needed someone's help to put it on to begin with.
The newly released WalkON Suit F1 presented a technical solution to this fundamental problem. It applied a frontal-docking method instead of a rear-sitting method so that you can wear the robot right away without getting out of the wheelchair and into the robot, which would require help from others mid-transition.

In addition, before wearing the robot, it can walk on its own like a humanoid robot and approaches the user. It is also implemented a function that actively controls the center of its weight against the pull of gravity so that it maintains balance without falling over even if the user pushes the robot otherwise. The outer design of the WalkON Suit F1, which crosses between a humanoid and a wearable robot, was done by Professor Hyunjoon Park of the Department of Industrial Design at KAIST.
The original function of the wearable robot has also been greatly improved. The performance of the balance control was improved to allow the free use of both hands in upright state, as well as the freedom to take several steps without a cane.
Technological advancements at the components level are also noteworthy. Through close collaboration with Angel Robotics, all core components of the robot, such as the motor, reducer, motor driver, and main circuit, have been domestically produced. The output density of the motor and reducer modules has been improved by about two folds (based on power per weight) compared to the research team's existing technology, and the control performance of the motor driver has been improved by about three times (based on frequency response speed) compared to the best overseas technology.
In particular, the embedded software technology of the motor driver has been significantly improved so that advanced motion control algorithms can be stably implemented without using expensive higher-level controllers. In addition, visual recognition system for obstacle detection and an AI board for neural network application have been installed.

Professor Kong explained, “WalkON Suit is the culmination of wearable robot technology for the disabled,” and added, “The numerous components, control, and module technologies derived from WalkON Suit are setting the standard for the entire wearable robot industry.”
Professor Kong’s research team revealed WalkON Suit F1 and announced that they will be participating in the 3rd Cybathlon, which is being held after four years since the last event. In this competition, which will be held on October 27, Professor Kong’s lab, the Exo Lab will be participating with Jeongsu Park, a Ph.D. Student, as the leader and Seunghwan Kim, the lab’s staff researcher with complete paralysis, as the competing athlete.
The difficulty of the missions in this competition has been significantly increased compared to the previous competition, and the number of missions has increased from six to ten. Some missions have been criticized for being overly challenging, going beyond the level that can be encountered in everyday life.

Regarding this, the team leader Jeongsu Park expressed his ambition, saying, “Since we already won first place in the previous competition, our goal in this competition is to show the technological gap rather than competing for rankings.”
The Cybathlon is a cyborg Olympics held every four years in Switzerland. This competition will be held in a hybrid format, with some participants taking part in Switzerland while others broadcasting live from stadiums in their own country on October 27. Professor Kong's research team will be participating via live broadcast from the competition facilities installed in Angel Robotics' Advanced Research Institute (Planet Daejeon).

Fundraising for the 50th Anniversary Memorial Building Kicks Off
KAIST started the fundraising campaign to construct the 50th Anniversary Memorial Building. This is one of the projects and events the 50th Anniversary Commemorative Committee established to celebrate the anniversary.
The ground will be broken in 2022 after raising approximately 50 billion KRW through 2021. The five-story building will be the latest addition to the KAIST campus. To highlight the campus’s history, the new building will connect the N5 (Basic Experiment & Research) and N2 (Administration Branch) buildings, the first buildings on the main Daejeon campus after its main campus moved from Seoul in 1987. Currently, the College of Business remains at the Seoul campus.
The 50th Anniversary Memorial Building will connect the two buildings in the shape of C, and represent KAIST’s C3 core value of Challenging, Creating, and Caring. The concept of this building was designed by Professor Sang-Min Bae from the Department of Industrial Design.
The 50th Anniversary Commemorative Committee said the Memorial Building will reflect the spirit of its core values. The first floor will accommodate the auditorium and exhibition hall, showcasing the latest achievements in KAIST innovation and convergence research as well as alumni startups and companies. The second floor will be an education space for entrepreneurship and video studios. An area for delivering creative education platforms such as Education 4.0 will be prepared on the third floor. The fourth floor will be used for global leadership education. The fifth floor will house the KAIST Club, a lounge for alumni and the Global Strategy Institute.
Co-Chair of the Fundraising & PR Sub-Committee of the KAIST 50th Anniversary Commemorative Committee and Former Vice President for Planning and Budget Seung-Bin Park and current Vice President for Planning and Budget Suchan Chae reiterated the importance of extending the infrastructure of the campus, saying that investments in the infrastructure will expand the university’s future growth potential. In a letter to kick off the fundraising efforts last month, they called for support from the entire KAIST community to help construct the new memorial building that will produce global talents and help young scientists make their dreams come true.
