Abstract: An inertial drive actuator includes a shift unit that generates a shift in a first direction and in a second direction opposite to the first direction, a base plate that moves with the shift of the shift unit, and a mover disposed on a surface of the base plate and having a magnetic field generating unit. The mover has a first yoke that guides magnetic flux generated by the magnetic field generating unit such that the magnetic flux concentrates on a surface of the mover facing the base plate with respect to both S and N poles. Also included is a second yoke provided on a side of the base plate facing away from the mover. The frictional force acting between the mover and the base plate is controlled by controlling a magnetic field generated by the magnetic field generating unit to drive the mover.

Abstract: A variable-stiffness actuator is to be installed into a flexible member and provide different degrees of stiffness to the flexible member. The actuator includes two hard members located apart from each other, and a shape-memory member connecting the hard members. The shape-memory member has a property of transitioning in phase between a first phase and a second phase. The shape-memory member is in a low stiffness state when in the first phase, and is in a high stiffness state when in the second phase. The actuator also includes a inducing member configured to cause a portion of the shape-memory member between the hard members to transition in phase between the first and second phases, and a urging member configured to urge the hard members in directions away from each other.

Abstract: An inertial drive actuator includes a shift unit that generates a small shift, a vibration base plate that moves to and fro with the small shift of the shift unit, a mover having a first magnetic field generating unit, a first yoke, and a second yoke. The first yoke and an end portion of the second yoke are opposed to each other at a position outside the vibration base plate, thereby restricting movement of the mover with respect to the direction perpendicular to the driving direction. The frictional force acting between the mover and the vibration base plate is controlled by controlling a magnetic field generated by the first magnetic field generating unit to drive the mover.
