Abstract
A compact angular actuator allows for angular displacement between a first section and a second section. The first section comprises a cam that is circular in cross section and has a wedge-shaped face. The second section comprises two or more constraint components that are in contact with the face of the cam. A hinge joins the first section and the second section in proximity with one another. As the cam is rotated about an axis that is perpendicular to and extends through a center of the circular cross section, the position on the face that the constraint components are in contact with changes. As a result, a force is imparted between the first section and the second section, changing the angular displacement between the two. The actuator fits within a compact volume and allows for precise controlled angular displacement, while allowing that displacement to be maintained without power consumption.
