Ekso is a wearable exoskeleton that can augment a person's physical capabilities. It's currently used to get people with lower-extremity paralysis or weakness standing up and walking.

The exoskeleton transfers its load directly to the ground so the user doesn't bear the weight of the device.
Ekso users have logged more than 100,000 steps (as of early 2012).

Originally Berkeley Bionics, Ekso Bionics began its evolution in 2005 with the ExoHiker, an exoskeleton that let able-bodied people carry 90 kg (about 200 lb) with minimal exertion. The technology was based on research developed at the University of California, Berkeley. In 2009, the company licensed its load-carrying Human Universal Load Carrier (HULC) system to Lockheed Martin for military development. In 2011, Ekso began testing a new version of its robotic suit in rehabilitation clinics in the United States and Europe. Ekso is now in use at 14 rehabilitation centers around the world. After more trials in clinics and hospitals, the company plans to introduce a model for at-home physical therapy.
