South Korean researchers from the Exoskeleton Laboratory at the Korea Advanced Institute of Science and Technology (KAIST) have created a lightweight wearable robot designed to assist paraplegic individuals in walking and performing other physical tasks. The device, called WalkON Suit F1, is powered by 12 electronic motors and uses sensors to simulate the movements of human joints. Weighing only 50 kg (110 lb), the exoskeleton enables users to walk, navigate obstacles, and even climb stairs. The goal of the researchers is to develop a robot that integrates seamlessly into the daily lives of individuals with disabilities, improving mobility and independence. Kim Seung-hwan, a paraplegic team member, demonstrated the robot’s capabilities by walking at a speed of 3.2 kph (2 mph) and performing various movements, such as climbing stairs and taking sideways steps.

The WalkON Suit F1 works by using sensors in its soles and upper body to monitor up to 1,000 signals per second, helping users maintain their balance. Lenses on the front of the robot act as eyes, analyzing the environment to detect obstacles and measure the height of stairs, compensating for the lack of sensory ability in individuals with complete paraplegia. This innovation has the potential to greatly enhance the quality of life for users, offering greater mobility and autonomy. During the Cybathlon 2024 event, Kim Seung-hwan, wearing the WalkON Suit F1, earned a gold medal in the exoskeleton category. The development of such technology marks a significant step forward in assistive robotics, bringing the vision of helping people with disabilities closer to reality.
