Abstract: This study presents the configuration and modeling of an electro-rheological (ER) fluid-based haptic master device for minimally invasive surgery (MIS). The haptic master device can produce a 3-DOF rotational motion which is realized by ER bi-directional clutch/brake for X and Y axes and ER brake for Z axis. In order to transmit a complex rotation from the handle of the device to three rotary movements, a gimbal structure is adopted. Before manufacturing the proposed haptic master, two case of design parameters are detemined from the viewpoint of compact size and extensive workspace, respectively.
