abstract:A powered exoskeleton, also known as powered armor, exoframe, or exosuit, is a mobile machine consisting primarily of an outer framework (akin to an animal's exoskeleton) worn by a person, and a powered system of motors or hydraulics that delivers at least part of the energy for limb movement.
The prototypedeviceis calledthe Lower-extremity Powered ExoSkeleton, or LOPES, and worksbytrainingthebodyandmindof a patient to recover a more natural step.
While many offer leg support, a team from University of Pennsylvania recently took silver in an engineering competition for its TitanArm prototype, a powered upper-body exoskeleton that, as the picture above shows, allows you to out-rep anyone at the gym.
