RAISE - An Innovative Parallel Robotic System for Lower Limb Rehabilitation

Robotic rehabilitation is a developing field of research which could become a necessity in the next decades due to the natural shifting of the population age. The aim of the paper is to present an innovative robotic device for the rehabilitation of the lower limb of patients in the acute post stroke phase. The parallel robot has a modular construction enabling the mobility of each major joint: hip, knee and ankle. Furthermore, the robotic system kinematics is presented and the singularities are derived, to validate the proposed system for its intended medical task, considering the upper limb motion requirements for the rehabilitation exercises.
