Expert highlights benefits, barriers in adoption of wearable robotics in occupational industry

An expert and Doctoral student at Virginia Tech, Akinwale Okunola, has highlighted the benefits, as well as barriers in the adoption of wearable robotics in the occupational industry.

Okunola, who specialises in robotics for the occupational industry, in a report, described wearable robotics as a promising field that augments human capabilities and reduces the physical strain associated with demanding occupational tasks.

He explained that his decision to dedicate his research to wearable robotics stemmed from the need to explore the integration of advanced technologies to enhance workers’ safety and productivity. 

Okunola argued that while occupational industries, such as construction and manufacturing, are known for their physically demanding tasks,  workers in those fields, he noted, often face over-exertion and strain, leading to musculoskeletal disorders (MSDs). 

These injuries, he stated, not only cause significant pain and discomfort but can also result in long-term disability and, in severe cases, death. 

Okunola, therefore, believed that the high incidence of MSDS has made innovative solutions imperative to protect workers and improve their quality of life, noting that addressing these challenges is crucial for maintaining a healthy and productive workforce.

“Wearable robotics presents an innovative approach to addressing the physical challenges faced by workers. Unlike fully automated robots that replace human labour, wearable robotics are designed to augment human strength and endurance. 

“These devices can significantly reduce muscle fatigue and the risk of injury by providing support and assistance during physically demanding tasks,” he stated. 

Okunola argued that by integrating wearable robotics, industries will be able to enhance worker safety and productivity, without compromising human involvement, adding that the technology represents a shift towards a more collaborative interaction between humans and machines, with the strengths of both leveraged to achieve better outcomes.

On the benefits of wearable robotics, Okunola identified reduction in muscle fatigue, as a primary advantage; since the devices can alleviate the physical strain on workers, allowing them to perform tasks more efficiently and for longer periods. 

“This not only improves productivity but also enhances worker well-being. Additionally, wearable robotics help prevent overexertion, a common cause of workplace injuries.

“By providing mechanical support, these devices reduce the likelihood of workers pushing their bodies beyond safe limits. Furthermore, wearable robotics can mitigate the risk of work-related musculoskeletal disorders by supporting proper posture and movement, thereby reducing the likelihood of injury,” he stated.

Okunola, however, argued that despite the numerous benefits, there are several barriers to the widespread adoption of wearable robotics in the occupational industry. 

One of such significant barrier is the high cost of those devices, which he described as  ‘prohibitive’, especially for small and medium-sized enterprises.

Besides, he argued,  some wearable devices may cause discomfort or restrict movement, making them less appealing to workers.

“Biomechanical misalignment is another concern; improper alignment of wearable robotics can lead to biomechanical issues, potentially causing more harm than good. The added weight and bulk of wearable devices can also increase the risk of falls, particularly in environments with uneven terrain. Moreover, the need to operate and manage wearable robotics can add to the cognitive load of workers, potentially affecting their performance and safety,” he stated.

Okunola noted that one of the ways to overcome these barriers is by developing wearable robotics, tailored to the specific needs and challenges of each industry. This, he argued, will enhance their effectiveness and adoption. 

He also believed advances in materials and design can help reduce the weight and bulkiness of wearable devices, making them more comfortable and less intrusive. 

“Efforts to lower the cost of wearable robotics through mass production and technological advancements can make them more accessible to a broader range of industries. Designing user-friendly interfaces and controls can reduce the cognitive load on workers and facilitate the seamless integration of wearable robotics into their daily tasks”, he stated.

Okunola, therefore, expressed optimism about the future of wearable robotics in the occupational industry, noting that with continued research and development, its full potential will be unlocked.
