Assessment of Powered Ankle Exoskeleton on Human Stability and Balance
While wearable robotic systems such as exoskeletons are designed to assist in human motion, they are often only studied in situations of level walking. In order to expand the types of actions for which exoskeletons can assist, the exoskeletons must be tested in a variety of situations to understand …

Design of an Ankle Exoskeleton Employing Dual Action Plantarflexion Assistance and Gait Progression Detection
… promising developments, the usefulness of exoskeletons in everyday settings remains limited due to design factors that include the limited practicality of existing battery technologies, the need for actuators exhibiting a high output torque-to-weight ratio, a need for modular designs that …

Autonomous powered exoskeleton to improve the efficiency of human walking
… have strived to develop autonomous leg exoskeletons that reduce the metabolic energy consumed when humans walk and run, but such technologies have traditionally remained unachievable. In this thesis, I present the Augmentation Factor, a simple model that predicts the metabolic impact of …

Autonomous active ankle exo-skeleton devices provide metabolic cost reduction
… with the usage of an autonomous active ankle exoskeleton. The primary method to identify the associated metabolic costs was through the comparison of cardiovascular and respiratory activity during gait with and without the use of the exoskeleton. Rates of oxygen consumption, carbon …

Design of A Variable-Stiffness Ankle-Foot Orthosis Emulator
Ankle-foot orthoses (AFOs) are passive devices used to improve gait in children with cerebral palsy. They are characterized by a torsional stiffness and ankle neutral angle. For this project, a lightweight ankle exoskeleton was designed to emulate the spring-like behavior of a traditional AFO for a …

FlexSEA : flexible, scalable electronics architecture for wearable robotic applications
… powered prosthetic knee as well as an autonomous ankle exoskeleton. To assess the usability of the FlexSEA kit, a new user successfully used a kit to read sensors and control an output device in less than three hours. FlexSEA simplifies and accelerates wearable robotics prototyping.
