South Korea’s Iron Man robot : A team of South Korean researchers from the Korea Advanced Institute of Science and Technology (KAIST) has created an Iron Man-like robot for paralyzed people. This robot is designed to help paraplegic individuals regain mobility. The robot (which cannot walk) approaches people and attaches itself to their bodies, after which it helps them walk, cross obstacles and climb stairs. This robot provides a new dimension of independence for paralyzed people.

The powered exoskeleton called WalkOn Suit F1 weighs just 50 kilograms (110 pounds) and is made of aluminum and titanium. Equipped with 12 electronic motors, it mimics natural joint movements, providing a comfortable walking experience. Sensors in the robot's soles and upper body capture more than 1,000 signals per second, helping it predict the user's intentions and maintain balance during movement.
“It can come to me wherever I am, even when I'm sitting in a wheelchair, and help me stand up,” said Kim Seung-hwan, a paraplegic member of the KAIST team who demonstrated the suit. “, which is one of its most distinctive features.”
Kim demonstrated the robot's versatility by walking at a speed of 3.2 kilometers per hour (2 mph), climbing stairs and turning sideways to sit on a bench. Their demonstration highlighted the potential of robots in increasing independence for individuals with disabilities.
Team member Park Jeong-soo took inspiration from the superhero film Iron Man. “After watching Iron Man, I thought it would be great if I could help people with robots in real life,” he said. The exoskeleton also includes advanced “eyes” – lenses that analyze the surrounding environment, assess the height of stairs and detect obstacles. This feature compensates for the sensory limitations of users with complete paraplegia, providing an additional layer of safety and autonomy.
