Robotic ankle exoskeletons have the potential to extend human ability, and actuation timing serves as one of critical parameters in its controller design. While many experiments investigated optimal values achieve different objective functions ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">e.g.</i> minimizing metabolic cost), studies on users’ perception control are gaining interest it gives information people’s comfort, coordination,...
Exoskeletons have the potential to assist individuals in completing daily tasks and augment industrial workers labor-intensive jobs. While previous studies shown capability of powered upper limb exoskeletons reduce muscle effort maintain task performance continuous cyclical movements, their effectiveness natural movements that contain both dynamic static remains uncertain. This study aimed investigate impact visual haptic electromyography (EMG) biofeedback on participants <inline-formula...
Wearable robotic systems are a class of robots that have tight coupling between human and robot movements. Similar to non-wearable robots, it is important measure the trust person has can support achieving desired goals. While some measures may apply all potential roles, there key distinctions wearable systems. In this paper, we considered dimensions sub-dimensions trust, with example attributes defined for exoskeleton applications. As research community comes together discuss will be...
Exoskeletons have the potential to support daily activities by assisting movement performance. Previous studies shown that powered elbow exoskeletons can reduce muscle effort during continuous cyclic movement. However, natural movements embedded stationary hold periods as well transitions between postures. The human performance when using for more should be evaluated. In this study, we implemented visual and haptic electromyography (EMG) biofeedback help people use an upper limb exoskeleton...
Actuation timing is an important parameter in powered ankle exoskeleton control that can significantly influence user experience and human-system performance. Previous studies have investigated the actuation through optimization under different objective functions, such as minimizing metabolic cost. However, little known about people's psychological sense of timing. This pilot study measured two subjects' sensitivity to small changes during walking. The just-noticeable difference (JND)...
