Researchers at Japan’s Keio University have developed a wearable robotic tail designed to help elderly users maintain their balance. Inspired by animal biology, the device functions as a counterbalance to prevent falls. This innovative approach to biomimicry aims to provide physical stability for those with mobility challenges.

 

The one-meter device, named Arque, straps around the waist and utilizes pneumatic artificial muscles to move in eight directions. It acts like a pendulum, automatically shifting its weight in the opposite direction of the user's lean. This real-time adjustment helps restore the wearer's center of gravity during movement.

 

Beyond elder care, the research team is exploring industrial applications to assist workers carrying heavy loads. By stabilizing the body during strenuous tasks, the technology could reduce workplace injuries. It represents a unique fusion of robotics and biology to solve human physical limitations.
