Abstract

This paper touches upon the issue of designing of an upper-limb exoskeleton used for rehabilitation. Mainly there are presented the results concerning the mechanical design. The exoskeleton, also known as orthosis, has 12 degrees of freedom (DOF). Among 12 DOF there can be distinguished 7 DOF which are actively controlled during rehabilitation, 3 passive DOF which are responsible for wrist movements, and 2 adjustable DOF used for links elongation. An orthosis has been specifically designed to accomplish requirements of medical applications. Described exoskeleton is a key-component of the upper-limb rehabilitation robot.

Projekt egzoszkieletu przeznaczonego do rehabilitacji kończyny górnej

Streszczenie

Artykuł opisuje zagadnienia konstrukcyjne związane z projektem egzoszkieletu przeznaczonego do rehabilitacji kończyny górnej. Egzoszkielet, zwany również ortezą, ma 12 stopni swobody. Wśród nich można wyróżnić 7, które są aktywnie sterowane w trakcie przebiegu rehabilitacji, 3 bierne związane z ruchami nadgarstka oraz 2 stopnie swobody nastawcze, związane z dostosowywaniem ortezy do długości kończyny pacjenta. Opisywany egzoszkielet jest kluczową częścią opracowanego robota rehabilitacyjnego.

Słowa kluczowe
