Powered exoskeleton

A powered exoskeleton, also known as powered armor, exoframe, or exosuit, is a mobile machine consisting primarily of an outer framework (akin to an insect's exoskeleton) worn by a person, and powered by a system of motors, hydraulics, pneumatics or levers that delivers at least part of the energy for limb movement.

The main function of a powered exoskeleton is to assist the wearer by boosting their strength and endurance. They are commonly designed for military use, to help soldiers carry heavy loads both in and out of combat. In civilian areas, similar exoskeletons could be used to help firefighters and other rescue workers survive dangerous environments. The medical field is another prime area for exoskeleton technology, where it can be used for enhanced precision during surgery, or as an assist to allow nurses to move heavy patients.

Working prototypes of powered exoskeletons, including XOS by Sarcos, and HULC by Lockheed Martin (both meant for military use), have been constructed but have not yet been deployed in the field. Several companies have also created exosuits for medical use, including the HAL 5 by Cyberdyne Inc.
