Control of a Multi-finger Prosthetic Hand
Our novel prosthetic hand is controlled by extrinsic flexor muscles and tendons of the metacarpal-phalangeal joints. The hand uses tendon-activated pneumatic (TAP) control and has provided most subjects, including amputees and those with congenital limb absence, control of multiple fingers of the hand. The TAP hand restores a degree of natural control over force, duration, and coordination of m...
متن کاملRobust Control of a Prosthetic Hand Finger
In this study, first, human hand anatomy is investigated dynamically. The tendon configuration of the fingers are also introduced and then modeled to imitate a real human hand index finger in the study because the actuating elements of the fingers are tendons on the phalanges. The prosthetic hand finger model is aimed to replace a real index finger of an amputated human. Therefore, artificial t...
متن کاملSliding Mode Control of a Finger for a Prosthetic Hand
A prosthetic finger model, intended to imitate a real human hand and for use in replacing the real index finger of an amputee, is designed using tendons instead of joint motors. A dynamic model of the prosthetic finger model is developed, and a non-chattering robust sliding mode control is applied to make the model follow a certain trajectory. Trajectory planning of the finger model is based on...
متن کاملMyoelectric Control of Prosthetic Devices for Rehabilitation
Bio-signals patterns analysis problems have enjoyed a rapid increase in popularity in the past few years. The electromyography (EMG) signal, also referred to as the Myoelectric signal (MES), recorded at the surface of the skin, is one of the biosignals generated by the human body, representing a collection of electrical signals from the muscle fibre, acting as a physical variable of interest si...
متن کاملProsthetic Hand Finger Control Using Fuzzy Sliding Modes
In order to improve the life quality of amputees, providing approximate manipulation ability of a human hand to that of a prosthetic hand is considered by many researchers. In this study, a biomechanical model of the index finger of the human hand is developed based on the human anatomy. Since the activation of finger bones are carried out by tendons, a tendon configuration of the index finger ...
