What if a simple vest could cut the effort required for certain tasks in half? Hyundai and Kia have developed a non-motorized device that combines lightness, durability, and efficiency, offering valuable mechanical assistance without the use of batteries.
The "X-ble Shoulder" is an exoskeleton worn like a vest. Weighing only 1.9 kg (4.2 lbs), it uses carbon arms capable of absorbing repetitive muscular effort. According to the manufacturers, it reduces shoulder strain by 60% and decreases deltoid muscle tension by 30%. This innovation promises less grueling workdays.
Unlike other motorized solutions, this device relies on a muscle compensation mechanism. Its patented module can endure up to 700,000 annual bending and unbending movements without requiring recharging. This feat is made possible by its clever multi-branch structure.
Two versions are available: a basic model designed to ease handling and an adjustable version that supports up to 3.7 kg (8.2 lbs) of weight. The latter, particularly suited for repetitive tasks, aims to provide users with personalized assistance based on their specific needs.
Initially developed for the production lines of both car brands, the "X-ble Shoulder" will be deployed in their factories starting in 2025. The companies then plan to commercialize it globally in 2026, particularly in Europe and North America.
This innovation is part of a broader range of exoskeletons developed by Hyundai and Kia. The "X-ble Waist" focuses on tasks involving heavy lifting, while the "X-ble MEX" assists individuals in motor rehabilitation. These devices illustrate the companies' commitment to transforming working conditions.
The modular design of the "X-ble Shoulder" allows for easy maintenance and compatibility with various professional outfits. Additionally, its removable and washable vest offers practical advantages for extended daily use.
Beyond the automotive and construction sectors, this exoskeleton could find diverse applications, from agriculture to aviation. The goal is clear: to reduce the risk of musculoskeletal injuries and improve productivity while preserving workers' health.
The wearable robot and exoskeleton markets hold enormous potential. Mordor Intelligence estimates they could grow from $2.5 billion to $10.25 billion by 2029. Hyundai and Kia hope their technology will be a decisive step in this evolution.
How does a non-motorized exoskeleton work?
A non-motorized exoskeleton relies on passive mechanisms to provide targeted support for body movements. Unlike motorized versions, it doesn't require a battery or motor, making it lightweight and easy to maintain.
The secret lies in its structures made from advanced materials, such as carbon, which absorb and redistribute muscular effort. These components adapt to movement to lessen the loads borne by the body, thereby reducing fatigue.
These devices often integrate muscle compensation modules. These use multi-branch structures or springs to generate assistance without electric intervention, ensuring durability and reliability.
With their simple and modular design, these exoskeletons find varied applications: relieving workers, preventing injuries, or even assisting in motor rehabilitation. Their effectiveness comes from seamlessly blending into daily routines without energy constraints.
