Basic Research of 'MR-PLEMO': 2-D Passive-Type Rehabilitation System for Upper Limbs Using MR Fluid Brake

摘要

Rehabilitation for the upper limbs is important for elderly people, people who have suffered strokes, and so on. In recent years, the need for rehabilitation support systems is increasing that use force display systems. When using a force display system, it is most important to ensure safety mechanically in order to prevent operators from hurting subjects. Conventional force display systems are active systems with actuators and these systems may become dangerous when going out of control. Passive force display systems with only passive elements are, however, thought to be an effective method for assuring inherent safety. In this paper, we evaluate force display ability for a 2-D passive-type force display system using fast-response MR (Magneto-Rheological) fluid brakes in order to apply this system to rehabilitation training.
