Abstract
A differential actuator including: a shuttle supported for rotation around a central axis and including a body portion, a first pinion gear connected to the body portion, and a second pinion gear connected to the body portion; a first component including a first plurality of teeth meshed with the first pinion gear and supported for rotation around the central axis; and a second component including a second plurality of teeth meshed with the second pinion gear and supported for rotation around the central axis. For a first operating mode of the differential actuator: the shuttle is arranged to be rotated by an actuator in a first circumferential direction around the central axis; and the first pinion gear is arranged to rotate the first component in the first circumferential direction around the central axis.
