A Model Hand Prosthesis Controlled by Foot and Toe Movements

Resumo

An approach to controlling hand prostheses using foot and toe movements is proposed. Construction of a model hand prosthesis with independent finger movements is described. A wireless remote control system for the prosthesis by tactile insoles fitted into the shoes is presented. Transfer parameters are selected by a synthesis based on the required final foot positions in the input and output sides of the system. Pneumatic bellows parameters, bracing spring stiffness, and pressure in the pneumatic circuit are selected on the basis of size restrictions and forces on the fingers. The study was supported by the Russian Foundation for Basic Research (Grant No. 16-08-00305A).
