The human spine has a unique “S” shape that allows for upright posture and bipedalism, freeing the upper limbs for tool use, artistic pursuits, and technological advances. . However, this evolutionary adaptation comes at a cost. The upright posture places significant biomechanical stress on the spine, especially when lifting heavy objects or performing repetitive movements. Over time, these stresses can lead to debilitating illnesses such as lower back pain, herniated discs, and other musculoskeletal disorders. Some time ago we discussed the use of exoskeletons in various fields and their rapid technological advancement. This time, Korean researchers announced. Cutting-edge exoskeleton Designed to reduce these risks, it provides an innovative solution to protect spinal health during physically demanding tasks.
BBEX: Exoskeleton for a safe working environment
Unlike traditional exoskeletons, this device developed by researchers at Seoul National University replicates the human spine and directly supports the vertebrae. named Bilateral posterior exoskeletal extensors (BBEX)The prototype was announced. science roboticsaccompanied by a study describing its development and testing.
Inspired by the human spine and its musculature, BBEX features multi-degree-of-freedom structures and connected linear actuators. This design naturally follows the movement of your spine, providing continuous support from all angles. This device significantly reduces muscle fatigue and joint loads during lifting tasks, whether performed symmetrically or asymmetrically.
In addition, BBEX incorporates advanced sensors that monitor the user’s posture and momentum in real time. These sensors enable adaptive assistance, optimizing both user support and comfort. The exosuit’s ergonomic and lightweight design improves ease of use in work environments where agility of movement is important.
To evaluate the prototype, the research team conducted tests on 11 healthy participants. Designed for environments that require heavy lifting, BBEX has demonstrated the ability to reduce muscle fatigue, reduce joint compressive forces, and provide multifaceted support. These features can significantly reduce workplace injuries. Developers highlighted its potential in industries such as construction where safety is paramount, but acknowledged there are challenges. Creating customizable models It can be used to suit users of different heights and physiques.
walking exoskeleton
In addition to their use in working environments, exoskeletons are being studied to restore mobility to people with physical disabilities. A French company specializing in wearable robotics has proposed using these devices for people with conditions such as paraplegia.
During the Paris Olympics, torchbearers demonstrated the feasibility of this technology by carrying the torch while walking with the help of an exoskeleton called a. Atalantadespite having suffered from paralysis since the age of 11.
Paralympic tennis player Kevin Piette was one of the first athletes to test Atalanta, which is already used in rehabilitation programs in the United States. The exoskeleton that supports the legs is equipped with a motor and battery system that is carried on the back like a backpack. The user operates via the remote control and adjusts both the direction and level of assistance from mild to full.
If the BBEX exoskeleton prototype for injury-free work piques your interest, it’s worth considering further advances in exoskeleton technology. For example, some exoskeleton suits can easily lift up to 200 hundred pounds. Additionally, we previously covered other safety innovations for the construction industry, such as wearable devices for jobsite protection.
