Abstract

Powered exoskeletons are designed to assist and protect the wearer. Depending on the situation they may be used to protect soldiers and construction workers, aid the survival of people in dangerous environments, or assist patients in rehabilitation. Regardless of the application there are strict requirements for designing and producing exoskeleton suites. They must be durable but light weight and flexible, have reliable power control and modulation, capable of detecting unsafe and invalid motions, and may require significant weight lifting capabilities. In this article we present an on-going research on robotic exoskeleton replicating of human muscle functions. A single wearable knee-joint prototype described in this article combines the use of soft pneumatic muscle-like actuators and a control system based off the users own natural muscle signals. The Pneumatic Exoskeleton uses bioelectrical signals to detect movement intention from the pilot. This paper details the technical design aspects of a lower-limb robotic exoskeleton with possibility of further expansion to fully functioning robotic exoskeleton suit. © 2013 IEEE.
