Application of actuators using particle-type ER fluids for force display devices, master-slave systems, and medical treatments and welfare

摘要

We developed ER actuators with low intertia. An ER actuator is a clutch which uses an electrorheological fluid. It is shown that this actuator has good properties for force display device, physical therapy treatment, etc. We also developed new force display devices for virtual reality which use ER actuators.
