Work-related injuries are common, especially when lifting and carrying heavy objects.

But now, a groundbreaking wearable robot called WeaRo could help workers avoid these injuries while staying mobile and efficient.

Developed by researchers from Yonsei University in South Korea, this innovative device was recently featured in Advanced Intelligence Systems.

Unlike many wearable robots that only support one type of movement, WeaRo is designed to help with multiple movements, making it more practical for real-world tasks.

WeaRo works by reducing the strain on key muscles during heavy lifting or repetitive motions.

In tests, it lowered muscle activity in the back (lumbar) by up to 18.2%, and in the arms (biceps and triceps) by 29.1% and 27.0%, respectively. This means workers could perform tasks with less effort and reduce the risk of injuries.

Despite its advanced capabilities, WeaRo remains lightweight, weighing less than 11.5 pounds (5.2 kilograms), including the batteries. Importantly, it doesn’t restrict movement, so workers can continue to move naturally while wearing it.

Dr. Dongjun Shin, who led the research, highlighted the importance of the project. “This study is significant because it develops a complete method to analyze movement, design wearable robots, and prove their effectiveness in preventing workplace injuries,” he explained.

By combining thoughtful design with rigorous testing, WeaRo represents a big step forward in wearable robotics. Its ability to support multiple movements while easing muscle strain could make a real difference in physically demanding jobs.

With further development, WeaRo could help workers stay safer and healthier while taking on tough tasks. This promising technology might soon become a valuable tool for industries like construction, warehousing, and healthcare.
