Atlas 2020
A wearable gait exoskeleton for children with neuromuscular diseases. The pediatric gait exoskeleton ATLAS has been designed to provide walking capabilities to children affected by paraplegia, tetraplegia, Spinal Muscular Atrophy, CMD, and Myopathies. The exoskeleton provides 3D walking. The dimensions are easily adjustable to child growth, and only requires 5 minutes to attach to the body. This model requires an auxiliary frame attached to the exoskeleton to control lateral stability. The exoskelton includes ARES technology for intelligent joint stiffness control. The physical user interface is based on motion intention detection.

Overview
The pediatric gait exoskeleton ATLAS has been designed to provide walking capabilities to children affected by paraplegia, tetraplegia, Spinal Muscular Atrophy, CMD, and Myopathies. The exoskeleton provides 3D walking. The dimensions are easily adjustable to child growth, and only requires 5 minutes to attach to the body.
This model requires an auxiliary frame attached to the exoskeleton to control lateral stability. The exoskelton includes ARES technology for intelligent joint stiffness control. The physical user interface is based on motion intention detection.
The exoskeleton’s architecture is built around long support rods, or orthoses, which are adjustable to snugly fit the child’s legs and torso. The joints are powered by a set of servo motors to mimic the effort of human muscles, providing the child with the necessary strength to stand upright and to walk. A series of sensors feed into an onboard computer to tracks the child’s steps in order to create the smoothest mechanical gait possible.
The entire apparatus is outfitted with telescoping supports that allow the mechanism to adjust as a child grows in height. A movement controller and a battery providing five hours of life between recharges complete the engineering components
