Abstract: Lower extremity exoskeleton system is a kind of human-machine robot, which combines the artificial intelligence with the power of mechanism. Recent years, the field of lower extremity exoskeleton robots have rapidly evolved and development of relevant technologies have dramatically increased these robots available for facilitating human walking function that could only be imagined a few years ago. Some technologies are so new that they lack the scientific evidence that would justify their use in the real setting. This paper presents an over view of design configurations, control methods and simulation test used for lower extremity exoskeleton robots. Further research efforts are required in order to incorporate many of the new technologies described in this review to promote the development of the lower extremity exoskeleton robots.
