Using bio-metric signals such as muscle and neuron signals through intelligent control systems to mimic human behavior, recovery of human organ function and rehabilitation in health care or remove human beings from hard or dangerous working condition has been an active research area especially in recent decades. This research attempts to develop a cost effective bio-driving robotic system for hand...
In this paper a case study is introduced, which assesses the suitability of a newly conceived two-channel myoelectric controller for a multi-fingered hand prosthesis. A PCA-based approach, previously presented by the authors, has been employed to control in real-time an underactuated 16-degrees of freedom robotic hand. A volunteer able-bodied subject was enrolled in this case study to test the system,...
Advanced myoelectric hand prostheses aim to reproduce as much of the human hand's functionality as possible. Development of the control system of such a prosthesis is strongly connected to its mechanical design; the control system requires accurate information on the prosthesis' structure and the surrounding environment, which can make development difficult without a finalized mechanical prototype...
The myoelectric signal has played a major role in the development of prosthesis control technology. A myoelectric classification system has the ability to determine a prosthesis user's intent based solely on his or her muscle activity, thereby allowing for more intuitive prosthetic control. Much work has been done on the recognition of upper arm and gross hand movement tasks, but it was not until...
A combined 450,000 Americans suffer from multiple sclerosis, chronic carpal tunnel syndrome, and muscular dystrophy; debilitative disorders that result in a loss of muscle strength and dexterity within the afflicted individual. A controlled orthotic exoskeleton presents a solution by amplifying a user's residual strength to restore precision pinch and/or power grasp motions. In order to optimize system...
Reach-to-grasp tasks are composed of several actions that are more and more considered as simultaneously controlled by the central nervous system in a feedforward manner (at least for well-known activities). If this hypothesis is correct, during prehension tasks, the activity of proximal muscles (and not only of the distal ones used to control finger movements) is modulated according to the kind of...
