KAIST Develops Revolutionary Exoskeleton to Help Paraplegics Walk

WalkON Suit F1: A Game-Changer in Assistive Technology
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have unveiled an innovative wearable robot, the WalkON Suit F1, designed to empower paraplegic individuals to walk, navigate obstacles, and climb stairs.
The lightweight exoskeleton, created by KAIST’s Exoskeleton Laboratory, combines cutting-edge robotics with advanced sensory technology to enhance mobility for those with lower-body paralysis.
A Demonstration of Hope
The WalkON Suit F1 was demonstrated by Kim Seung-hwan, a paraplegic team member, showcasing its remarkable capabilities. Using the exoskeleton, Kim achieved a walking speed of 3.2 kilometers per hour, climbed stairs, and even stepped sideways to sit on a bench.
“One of its most distinct features is its ability to approach me wherever I am, even when I’m sitting in a wheelchair, and help me stand up,” Kim explained.
Advanced Features and Design
Weighing 50 kilograms, the exoskeleton is constructed from aluminum and titanium for durability and lightness. It incorporates:
- 12 electronic motors to mimic human joint movements.
- Sensors in the soles and upper body, collecting 1,000 signals per second to maintain balance and anticipate the user’s intended actions.
- Front-facing lenses acting as eyes, analyzing the environment, detecting obstacles, and measuring stair heights to compensate for users’ lack of sensory feedback.
The WalkON Suit F1’s design was partly inspired by the superhero film Iron Man. Reflecting on the inspiration, team member Park Jeong-su shared, “After watching Iron Man, I thought it would be great to help people with a robot in real life.”
A Personal Milestone and International Recognition
Kim’s use of the WalkON Suit F1 earned him the gold medal in the exoskeleton category at Cybathlon 2024, a global event highlighting assistive robot technologies.
Sharing his motivation, Kim said, “I wanted to tell my son that I also used to be able to walk. I wanted to share a diverse range of experiences with him.”
A Leap Forward for Paraplegic Mobility
The WalkON Suit F1 represents a significant breakthrough in assistive technology, offering new possibilities for independence and mobility to people with paraplegia. With its advanced capabilities and human-centric design, the exoskeleton promises to transform lives and redefine what is possible for individuals living with disabilities.
