| Outline of Research at the Start |
This research firstly intends to investigate the interaction mechanism between human neuromuscular-skeletal system under multimodal perception and external mechanical assistance with great bandwidth gap. Secondly, developing neural networks models to generate electrical stimulation for control of human upper limb to realize collaborative motion with external mechanical assistance.

| Outline of Final Research Achievements |
The following aspects were achieved by this study. Firstly, electrical stimulation devices that can generate two channels of programmable electrical pulses with a max frequency of 1000Hz was developed. Closed-loop visual feedback control of human upper limb by the developed electrical stimulation from a range of 10Hz - 1000Hz was realized. Secondly, we developed the human-machine interaction system utilizing human visual and force feedback modalities and conducted the primary experimental studies on the interaction between human and external mechanical assistance of bandwidth in terms of bimanual coordination. As an early-stage study, we investigated and verified the possibility of human-machine interaction for accurate manipulation under human visual and force feedback utilizing the bimanual synchronous mechanism.

| Academic Significance and Societal Importance of the Research Achievements |
We developed the very first systems to incorporate high-bandwidth mechanical assistance into control of human upper limbs, and laid the foundation for future studies on human upper limb control by electrical stimulation and by bimanual coordination under high-bandwidth mechanical assistance.
