‘Iron Man’ Robot Helps Paraplegics Walk in South Korea
South Korea scientists have unveiled a groundbreaking innovation, the WalkON Suit F1, a wearable exoskeleton robot designed to assist paraplegics in walking, climbing stairs, and navigating obstacles. Developed by the Exoskeleton Laboratory at the Korea Advanced Institute of Science and Technology (KAIST), In conclusion the lightweight robot represents a major leap toward empowering individuals with mobility challenges.
A Vision of Integration
The WalkON Suit F1 can independently approach users, lock itself onto them, and enable them to stand and walk. Designed to integrate seamlessly into daily life,Secondly the robot has already given a glimpse of its transformative potential. Kim Seung-hwan, a paraplegic and a member of the KAIST team, demonstrated its abilities by walking at a speed of 3.2 kph (2 mph), climbing stairs, and maneuvering sideways to sit on a bench.
Secondly, “It can come to me wherever I am, even in my wheelchair, and help me stand up,” Kim shared, emphasizing the robot’s distinct functionality.
Engineering Inspired by Iron Man
The WalkON Suit F1 weighs 50 kilograms (110 pounds) and is crafted from aluminum and titanium. It operates using 12 electronic motors that replicate human joint movements during walking.
Park Jeong-su, one of the researchers, revealed that the robot’s design drew inspiration from the iconic superhero film Iron Man. “After watching Iron Man, I thought it would be amazing to create a robot that helps people in real life,” he said.
Adapting to the Environment
What sets the WalkON Suit F1 apart is its ability to adapt to various surroundings. Equipped with lens-based “eyes,” the robot can analyze its environment, detect obstacles, and identify staircase heights, compensating for the sensory limitations of users with complete paraplegia.
However Kim, who wore the exoskeleton during the Cybathlon 2024 competition, secured a gold medal in the exoskeleton category. The international event brought together developers and individuals with physical disabilities to showcase assistive technologies.

Empowering Users Beyond Mobility
For Kim, the WalkON Suit F1 represents more than just mobility—it signifies hope and shared experiences. “I wanted to show my son that I used to be able to walk. This robot helps me share those moments with him,” he expressed.
A Step Toward the Future
The KAIST team’s goal is to refine the WalkON Suit F1 for broader use, ensuring it becomes a reliable part of life for individuals with disabilities. With its innovative technology and human-centered design, the robot exemplifies how engineering can empower lives and transform challenges into opportunities.
