South Korean researchers at the Korea Advanced Institute of Science and Technology (KAIST) have unveiled an innovative wearable robot, the WalkON Suit F1, designed to assist paraplegics in regaining mobility. This exoskeleton, inspired by the fictional Iron Man suit, can autonomously approach users and lock onto them, enabling individuals to walk, climb stairs, and navigate obstacles. Weighing approximately 50 kg (110 lb), the suit is constructed from aluminum and titanium, making it lightweight yet durable. It is powered by 12 electronic motors that replicate human joint movements, allowing users to achieve a walking speed of up to 3.2 km/h (2 mph) while maintaining balance.

The development of the WalkON Suit F1 addresses previous limitations in wearable robotics, particularly the need for assistance when donning the device. The research team, led by Professor Gong Kyung-chul, focused on creating a system where users can independently wear the robot without external help. The suit utilizes a front-mounted design that allows it to wrap around the user seamlessly, facilitating a smooth transition from sitting in a wheelchair to standing upright. This breakthrough not only enhances user autonomy but also aims to improve the quality of life for individuals with severe mobility impairments.

Kim Seung-hwan, a paraplegic researcher involved in the project, demonstrated the suit's capabilities by walking and climbing stairs during a recent presentation. He expressed how transformative it is to interact with others while standing without assistance. The WalkON Suit F1 is particularly targeted at individuals with significant lower limb disabilities and features advanced balance control systems that enable users to walk several steps unaided. Additionally, the integration of artificial intelligence allows for enhanced obstacle detection and navigation, making it suitable for real-world environments.

The research team has made significant strides in localizing all core components of the suit, including motors and control systems. This localization results in improved performance metrics compared to existing technologies. Professor Gong's vision extends beyond this prototype; he aims to develop an AI-driven wearable robot akin to Iron Man's Jarvis system. As part of their ongoing efforts, the team will participate in the upcoming Cybathlon Competition, showcasing their advancements against international competitors in bionic assistive devices for disabled individuals.
