Abstract:

This study focuses on review and proposal of new configurations of bidirectional magneto- rheological actuator (BMRA) for force feedback application. Firstly, an introduction to development of haptic systems based on MR brakes is presented. The disadvantages of MR brake based haptic systems are then analyzed and the necessity for development of BMRA for haptic systems is figured out. After that, several configurations of BMRA including the previously developed and new proposals are introduced. The optimal design of the considered configurations of the BMRA is then conducted and the optimal results are evaluated. Some applications of the BMRA in haptic systems are shown with updated experimental results. In addition, some existing limitations of developed BMRA based haptic systems are shown and future research directions on BMRA based haptic systems are presented.
