South Korean researchers have developed a wearable robot to help individuals suffering from paraplegia. The researchers at the Korea Advanced Institute of Science and Technology (KAIST) designed it to be lightweight so that it can be worn comfortably. The weight of the exoskeleton is around 50 kg. The robot helps the users to walk, navigate obstacles, and even climb stairs. The robot is named WalkON Suit F1, which is made up of aluminum and titanium.
With 12 electronic motors, it replicates natural joint movements for smooth walking. Sensors in the robot’s soles and upper body collect over 1,000 signals per second to understand user intentions and keep balance while moving. It also features advanced eyes — lenses that are capable of scanning the surroundings, measuring stair heights, and spotting obstacles. This allows users to move easily and gain independence. The inspiration for this was taken from the Iron Man movie, said Park Jeong-su, a member of the KAIST team.
A paraplegic and member of the KAIST team, Kim Seung-hwan wore the exoskeleton and demonstrated the prototype. The exoskeleton let him walk at a speed of 3.2 kph (2 mph), climb stairs, and take sideways steps to sit on a bench. Kim also wore it at Cybathlon 2024 and won a gold in the exoskeleton category. The event showcased advanced assistive technology, with participants of different disabilities competing in eight categories.
