A successful substitution of the natural hand could be achieved only by developing an anthropomorphic device with high dexterity and an intuitive and easy-to-use control system.

Abstract
A successful substitution of the natural hand could be achieved only by developing an anthropomorphic device with high dexterity and an intuitive and easy-to-use control system. In this work a new approach to multi-Degrees-of-Freedom (DoFs) control based on Principal Components Analysis is proposed and assessed, which allows driving a 16-DoF multi-fingered hand prosthesis by means of only 2 differential EMG channels. Trials with able-bodied subjects demonstrated that they soon learned how to correctly operate the hand to firmly grasp objects, and confirmed that the developed control strategy is successful.File in questo prodotto:
