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.
