Abstract
Official abstract text for this publication.
An impact actuator with 2-degree of freedom, which may generate an impact stimulation in any direction on the plane, includes a body having a magnetic substance that is movable therein, one upper solenoid attached to an upper portion of the body, and three or more lower solenoids attached to a lower portion of the body, wherein the upper solenoid and the three or more lower solenoids are independently supplied with AC power from a power supply, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. An impact actuator with 2-degree of freedom, comprising: a body having a magnetic substance that is movable therein; one upper solenoid attached to an upper portion of the body; and three or more lower solenoids attached to a lower portion of the body, wherein the upper solenoid and the three or more lower solenoids are independently supplied with AC power from a power supply, respectively. 2. The impact actuator according to claim 1 , wherein the three or more lower solenoids are composed of the same four solenoids having a quartered cylindrical shape. 3. The impact actuator according to claim 1 , wherein the magnetic substance is fixed to a neutral position that is a center portion of the body, when a current is not supplied to the upper solenoid and the three or more lower solenoids. 4. The impact actuator according to claim 3 , wherein the magnetic substance is fixed by an attractive force with an iron member included at the neutral position of the body, the upper solenoid or the three or more lower solenoids. 5. The impact actuator according to claim 1 , wherein the magnetic substance collides with the body by an impact of a direction and strength, which are determined by whether or not to supply a current to the upper solenoid and the three or more lower solenoids, respectively, and by at least one of a direction of the current and intensity of the current. 6. The impact actuator according to claim 5 , wherein the magnetic substance returns to a neutral position after colliding with the body.
