26.7. Exoskeletons for Worker Augmentation: Ekso Bionics (USA)

Exoskeletons are wearable robotic suits that support the human musculoskeletal system, reducing fatigue and injury during heavy lifting.

Exoskeletons are advanced devices that can be worn like a suit. They are designed to help support the body, especially the muscles and joints, when a person is lifting heavy objects. This support can minimize the physical toll that lifting takes on the body, making it easier for workers to perform tasks that would normally cause fatigue or injury. The robotic suits operate by enhancing the natural movements of the human body and provide additional strength where needed.

Imagine a backpack that helps you lift heavy tools or boxes with ease. Just like a backpack can distribute weight more evenly across your body, an exoskeleton helps distribute the physical strain of lifting, enabling you to carry heavier items longer without feeling exhausted.

Used by workers performing repetitive overhead tasks.

At Skanska construction sites in the UK, workers utilize exoskeletons for tasks that require lifting or moving materials overhead repeatedly. Such tasks can be particularly strenuous, leading to fatigue or potential injuries if performed for long periods. By wearing these robotic suits, workers can lift more efficiently, reducing the risk of strain and increasing their comfort during work.

Think of the advantages of using a mechanical arm to help lift a heavy box to a high shelf. The exoskeleton acts like that mechanical arm but is worn on the body, helping to enhance the strength of the worker's own arms when they are doing their job.

Robot suit assists movement without replacing human control. Humans remain in full command but with reduced exertion.

The exoskeletons are designed to work in tandem with humans, enhancing their capabilities rather than taking over their tasks. This means that while the suit provides extra strength and support, the worker is still in complete control of their movements. The exoskeleton assists with tough tasks but does not replace the critical thinking and decision-making skills of the human user.

Consider the relationship between a driver and a car. The car provides the means to travel faster and further, but the driver remains in control of where to go and how to navigate. Similarly, the exoskeleton enhances a worker's physical capabilities while allowing them to maintain full control of their actions.

Increased work duration without strain. Fewer musculoskeletal disorders. Improved productivity.

Using exoskeletons presents numerous benefits for construction workers. They can work longer hours without feeling fatigued, significantly lowering the risk of injuries related to muscle and joint strain, such as back problems. This reduction in physical stress can also lead to overall better health for workers. Additionally, with improved physical endurance, productivity on construction sites can increase, as workers are able to accomplish more tasks in less time.

Think about a marathon runner who trains with weights to build endurance. When they run a marathon race, they can maintain their speed and stamina because they've built strength. Similarly, exoskeletons allow construction workers to maintain productivity levels for longer periods without becoming exhausted or injured.
