Abstract: A multi degree-of-freedom electromagnetic machine includes an outer case, an inner case, a stator, stator windings, a voice coil winding, a tilt magnet, a rotor, and rotor magnets. The inner case is disposed within an inner cavity of the outer case and is mounted to rotate relative to the outer case about one or more rotational axes. The stator is fixedly mounted within the inner case, and the stator windings are wound thereon. The voice coil winding is fixedly coupled to either the inner surface of the outer case or the outer surface of the inner case. The tilt magnet is fixedly coupled to either the outer surface of the inner case or the inner surface of the outer case. The rotor is rotationally mounted within the inner case and is operable to rotate, relative to the stator, about a rotational axis.

Abstract: A lightweight gear includes a hub, and a tooth ring defining a plurality of gear teeth. The tooth ring includes an inner core composed of a polymer-based material that is coupled to the lattice structure. The lightweight gear includes a lattice structure interconnecting the hub and the tooth ring. The lattice structure has a density that varies radially based on an operating condition of the lightweight gear and the lattice structure is composed of a metal or a metal alloy.

Abstract: A hybrid spherical motor includes a first gear box, a second gear box, a yoke arm, a brushless direct current (BLDC) motor, a spherical stator, and a spherical armature. The split armature, in response to the spherical stator being energized, rotates about a first rotational axis, thereby causing the first gear box input connection and the second gear box input connection to rotate about the first rotational axis, and the yoke arm rotates about the first rotational axis in response to the first gear box input connection and the second gear box input connection being rotated about the first rotational axis, whereby the BLDC motor rotates about the first rotational axis.
