Strengthening muscle force by training, e.g., an isokinetic exercise is widely used in rehabilitative activities or sports rehabilitations. However, many conventional isokinetic exercise machines are expensive because of their actuation devices and safety systems (hardware and software). In this study, we have developed highly safe isokinetic exercise systems using only brakes with functional fluids (Magnetorheological Fluid or MR Fluid). Because of rapid response of these fluids, such a machine has good response property and controllability. In this paper, we describe basic concept and characteristics of Isokinetic Exercise system using MR fluid brake and its experimental results. In particular, high-speed (900deg/s at an elbow joint) training can be realized in this system.
