Abstract:
A two degree-of-freedom actuator includes a first linkage, a second linkage, a third linkage, a magnet, a winding panel, and a plurality of windings. The second linkage is rotationally coupled to the first linkage, whereby the first linkage is rotatable, relative to the second linkage, about a first rotational axis. The third linkage is rotationally coupled to the second linkage, whereby the first and second linkages are rotatable, relative to the third linkage, about a second rotational axis that is perpendicular to the first rotational axis. The magnet is fixedly mounted on the first linkage. The winding panel is fixedly mounted to the third linkage and has an inner surface and an opposing outer surface. The inner surface faces the magnet and is spaced apart therefrom. The windings are wound around the winding panel.
