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 cost expensive depending on its actuation device and safety system (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 responsibility and controllability. In this paper, we describe basic concept and characteristics of Isokinetic Exercise system using MR fluid brake and its experimental result. In particular, High-speed (900[deg/s] at an elbow joint) control was realized with this system.
