Exoskeleton suits are robotic devices with an outer framework that is worn by an individual and a system of motors or hydraulics to provide energy for movement. The technology is under consideration for military, rescue and medical applications.
Exoskeleton suits can boost strength and endurance, allowing wearers to lift heavy loads and run faster and longer. The suits could help military and rescue personnel survive dangerous environments. They have the potential to help patients with spinal injuries or muscular weakness regain mobility and to assist nurses with moving heavy patients. Major challenges to current exoskeleton technology include reducing the weight of the systems, protecting wearers from collisions or movements that exceed the limits of the human body, and creating long-lasting portable power supplies to free users from being tethered to a power source.
