The objective of this work is to study the EMG signals based on hand motions for specified tasks, and different gripping conditions so as to identify patterns of EMG signals. This will allow therapists to identify weak muscles of patients with motor ...

The objective of this work is the study and analysis of the fundamental issues that constitute the development of a hand rehabilitation system by making use of mechanisms with systematic methodology for objective and quantitative assessment for patients ...

In this paper, a robotic fish employing a carangiform swimming mode have been developed. The tail fin mechanism with a spring and a movable pin enables a smooth adjustable motion. Experiments conducted in the laboratory aim to study the variation of ...

In this paper, a methodology for gait rehabilitation, combines over-ground walking, body weight support, pelvic control, and gait assistance are introduced and the integrated platform has been developed. This paper also discusses the gap of state-of-the-art ...

A two-channel bilateral controller is proposed for teleoperation systems. The controller takes into account both the free space motion and the constrained motion. Specifically, the force-position (F-P) architecture is applied during the constrained motion, ...

Self-organizing feature maps such as extended Kohonen maps (EKMs) have been very successful at learning sensorimotor control for mobile robot tasks. This letter presents a new ensemble approach, cooperative EKMs with indirect mapping, to achieve complex ...

In this paper, an effective method using the concept of virtual boundary is incorporated into the drop/impact simulation. Drop/impact-induced damage is one of the most predominant modes of failure electronic devices suffer in their usage. Drop/impact ...
