Robotic Exoskeleton (EXO)
From: NASA Tech Briefs - 11/01/2015

This wearable device can assist walking for persons with paraplegia, and can
be used in gait modification and rehabilitation.

The Exoskeleton (EXO) is a device that falls into a new classification of
robotics called wearable robots. On-orbit applications include
countermeasures and dynamometry, allowing for continual assessment of a
person’s muscle strength while aboard the International Space Station. Due to
its small, compact size and relatively light weight (57 lb without
batteries), EXO holds great promise as a countermeasure device for missions
below low-Earth orbit.
