Summary: The advantages of Bowden cable-based exoskeletons lie in their lightweight and flexible nature, making them convenient for human assistance. However, their performance is restricted by the exoskeleton's structure and human-exoskeleton interaction. In this study, control methods including disturbance observer, human-exoskeleton interaction feedforward model, and angle prediction using encoder are proposed to compensate for disturbances and limitations, thus improving the accuracy of assistance.

Summary: This survey systematically reviews various concepts and methodologies developed in the past two decades for studying the impedance or admittance of robotic systems that physically interact with humans. It categorizes and compares the assumptions and mathematical formulations for online adjustment of impedance models and controllers for physical human-robot interaction (HRI), while discussing strategies for variation and learning of appropriate impedance elements. Additionally, different methods involving linear/nonlinear analyses and Gaussian approximation algorithms are reviewed, along with current challenges and research trends in physical HRI.

Summary: This article introduces a lightweight exoskeleton wheelchair as a personal mobility device for lower-body impaired users. The exoskeleton utilizes a novel passive mechanism using a gas spring as an energy storage unit to provide postural transition support during sit-to-stand/stand-to-sit transitions. A direction-dependent coupling of knees and hip joints is achieved through a double-pulley wire system, maximizing energy transfer and natural movement. The device features an embodied user interface for hands-free navigation using torso pressure sensing. Evaluation on unimpaired users shows significant reduction in muscle activity during assisted sit-to-stand/stand-to-sit transitions. Natural torso leaning movements are also demonstrated. Further research is needed to enhance the applicability and expand the user population of the passive postural transition assistance.

Summary: This paper presents a periodic event-triggered sliding mode control scheme based on human-robot cooperation for lower limb exoskeletons. A Genetic Algorithm-Back propagation neural network is proposed to estimate the wearer's motion intention using electromyography signals.
