An exoskeleton system is a compact, light-weight robotic mechanism that a human can put-on for the purpose of overcoming inadequate muscle strength during the performance of physical tasks. In doing so, this integrated human-machine system offers multiple opportunities for creating assistive technologies that can be used in biomedical, industrial, aerospace and everyday life applications. The scope of the present research is to develop an advanced human-machine interface based on the electromyographic (EMG) signals. The resulting EMG control command is concerned with the detection, processing, classification and application to drive the exoskeleton system.
