Abstract:

Recent advances in wearable robotics have unveiled the potential of exoskeletons to augment human locomotion across a variety of environments.  However, few studies have evaluated the capability of these devices to augment human biomechanical stability during unstable locomotion, which could inform assistive devices for individuals with balance impairments, therapy strategies, and bipedal robotics.  In this proposal, I aim to investigate human responses while walking in destabilizing environments and the ability of exoskeleton assistance to compensate for human suboptimality in recovering and maintaining balance.  I propose extend these findings to design and test an intelligent exoskeleton control framework that augments human locomotor stability in novel environments.  To achieve this, I will (Aim 1) investigate human biomechanics following a diversity of destabilizing perturbations, (Aim 2) test the ability of exoskeleton controllers to augment stability by compensating for human latency, and (Aim 3) develop an intelligent control framework that predicts biological joint moment responses and applies them via assistive exoskeleton torques prior to the human’s response.  This work will introduce a novel intelligent bio-inspired approach for augmenting biomechanical stability during locomotion using wearable robots.
