| Outline of Final Research Achievements |
A displacement-amplified electromagnetic actuator was studied by focusing on actuation time for a simply full-stroke drive. The attempt revealed that the amplification contributes to a decrease in the actuation time of actuators using electromagnetic attractive force in some cases. Moreover, an inchworm mechanism using displacement-amplified electromagnetic actuators was studied as an application of displacement-amplified electromagnetic actuators including a control system. An experiment was conducted to show the applicability of this prototype to a rail that waves at the micrometer scale because the actuator allows shear deformation owing to the air gap. The experimental results implied that the flexibility of the actuator is useful for the motion of inchworm mechanisms on waving rails.
