RESUMEN
The lower extremity exoskeleton robot is a wearable device designed to help people suffering from a walking disorder to regain the power of the legs and joints to achieve standing and walking functions. Compared with traditional robots that include rigid mechanisms, lower extremity exoskeleton robots with compliant characteristics can store and release energy in passive elastic elements while minimizing the reaction force due to impact, so it can improve the safety of human-robot interaction. This paper reviews the compliant characteristics of lower extremity exoskeleton robots from the aspects of compliant drive and compliant joint, and introduces the augmentation, assistive, rehabilitation lower extremity exoskeleton robots. It also prospect the future development trend of lower extremity exoskeleton robots.
RESUMEN
@# 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.
