Abstract
The present invention is directed towards apparatuses for rotating a gimbaled platform with rotatable actuators. Gimbal springs comprised of component springs with compliant axes that intersect at a nonzero angle are coupled to the gimbaled platform. Preferably, the compliant axes of the component springs are oriented at an approximately 45 degree angle relative to the actuator rotation axes. Wraparound lever arms coupling the rotatable actuators with the gimbal springs serve to increase the leverage ratio, thereby permitting greater platform rotation for a given actuator rotation.
