Background Research efforts in neurorehabilitation technologies have been directed towards creating robotic exoskeletons to restore motor function in impaired individuals. However, despite advances in mechatronics and bioelectrical signal processing, current robotic exoskeletons have had only modest clinical impact. A major limitation is the inability to enable exoskeleton voluntary control in neurologically...
This paper deals with designing, developing and building one degree of freedom orthosis based on an active compliant actuator. To know human's intentions and the desired movements beforehand, we opted for electromyogram (EMG) signals collected by surface electrodes. Processing the EMG signals and controlling the orthosis are integrated into a unified framework that combine OpenSim and Robotic Operating...
In this paper, we present a control method of robotic system using electromyography (EMG) signals collected by surface EMG electrodes. The EMG signals are analyzed using a neuromusculoskeletal (NMS) model that represents at the same time the muscle and the skeleton of the body. It has the advantage of adding external forces to the model without changing the initial parameters which is particularly...
