Short summary
In rehabilitation, the widely existing misalignment between human limb and exoskeleton causes discomfort even danger. To alleviate the misalignment in lower extremity exoskeleton, this study proposes a compliant parallel mechanism, which has the potential to automatically change its configuration to make exoskeleton knee joint fit the human joint movements. And the self-alignment performance of the mechanism is validated via conducting a series of experiments under different working conditions.
