The WREX, Wilmington Robotic EXoskeleton, was designed at A. I. DuPont Hospital for Children.

The JAECO WREX is a state-of-the-art, light weight exoskeleton with two links and four degrees of motion that approximates normal human anatomy. It incorporates elastic band elevation assists for both the shoulder and elbow to totally eliminate gravity influence on the extremity. The unique design of the shoulder and elbow joints allow for a significant improvement in the available range of motion when compared to other assistive devices.

Developed for people with neuromuscular weakness such as muscle disease, cerebral palsy, spinal cord injury, multiple sclerosis and amyotrophic lateral sclerosis, that effect upper limbs, WREX acts as a functional aid in activities of daily living. It can also serve as a cost effective exercise/therapy device for people recovering from stroke.

The WREX can be attached to most common wheelchairs and mobility seating systems utilizing one of the three Mount Bases provided with the arm. These are the same attachment systems that are the basis of JAECO's Mount Relocator.

The WREX is assembled as left or right. The size is adjustable to fit most children through adult arms.
