Development of a prosthetic hand regarding complex motion and controllability

Abstract

In this paper, the critical issues of currently available upper limb prostheses are highlighted; also possibilities of usability improvement are propounded.Although contemporary prosthetic hand constructions are extremely complex and allow numerous movements, they do not give opportunities for many people, because of the difficulties in proper use and the high costs.Based on the aformentioned aspects, the development of such a construction has been started, that hopefully provide solutions both in the ease of use and in cost reduction.After giving a brief overview of upper limb prostheses and detailing the major difficulties, the current state of the device under development is presented, as well as the results of analysesand the direction of future research.
