Due to the hand biomechanical constrains and coordinate manner of motor control, single one joint is difficult to move independently. The aim of this paper is to have an analysis on the joint independence of hand and wrist. At first, a grasp experiment under the tolerance grasping was completed, and the hand and wrist joint angles in different grasping postures were recorded for representing the functionality...
A five-fingered, multi-sensory biomechatronic hand with sEMG interface is presented. The cambered palm is specially designed to enhance the stability while grasping. The location of the thumb is designed by maximizing interaction area between the thumb and other fingers. The opposite thumb could grasp along a cone surface, while maintaining its function. By taken the advantage of coupling linkage...
The multi-DOF prosthetic hand's myocontrol needs to recognize more hand gestures (or motions) based on myoelectric signals. This paper presents a classification method, which is based on the support vector machine (SVM), to classify 19 different hand gesture modes through electromyographic (EMG) signals acquired from six surface myoelectric electrodes. All hand gestures are based on a 3-DOF configuration,...
