Abstract
A pitch-yaw actuation system includes a pitch frame, a yaw frame, a pitch actuator, a yaw actuator, and a universal joint assembly. The pitch frame is pivotably coupled to a device frame via a pitch hinge. The yaw frame is pivotably coupled to the pitch frame via a yaw hinge. The pitch actuator pivots the pitch frame about a pitch axis. The yaw actuator pivots the yaw frame about a yaw axis oriented orthogonal to the pitch axis. The universal joint assembly couples the yaw actuator to the yaw frame, and includes a universal joint slidably coupled to a linear guide mechanism. The guide mechanism axis is oriented at an angle that allows the universal joint to move in a manner accommodating misalignment of the yaw actuator with the yaw frame during pivoting of at least one of the pitch frame and the yaw frame.
