South Korean team develops ‘Iron Man’ robot that helps paraplegics walk

South Korean researchers have developed a lightweight wearable robot that can walk up to paraplegic users and help them move.
South Korean researchers have developed a lightweight wearable robot that can walk up to paraplegic users and lock itself onto them, enabling them to walk, manoeuvre obstacles and climb staircases.
The Exoskeleton Laboratory team at the Korea Advanced Institute of Science and Technology (KAIST) said their goal is to create a robot that seamlessly integrates into the daily lives of individuals with disabilities.
Kim Seung-hwan, who is himself a paraplegic and part of the KAIST team, demonstrated the prototype which helped him walk at a speed of 3.2 kph (2 mph), climb a flight of stairs and take sideways steps to slide into a bench.
"It can approach me wherever I am, even when I’m sitting in a wheelchair, and be worn to help me stand up, which is one of its most distinct features," Kim said.
The powered exoskeleton, named WalkON Suit F1, features aluminium and titanium composition to weigh in at 50 kg (110 lb), and is powered by 12 electronic motors that simulate the movements of human joints while walking.
Park Jeong-su, another member of the KAIST team, said he was inspired by the movie "Iron Man". "After watching Iron Man, I thought it would be great if I can help people with a robot in real life."
To ensure the user's balance while walking, the robot is equipped with sensors on its soles and in the upper body that monitor 1,000 signals per second and anticipate the user's intended movements.
