A new ring cam and ring cam assembly, developed for providing more diverse dynamic pitching schedules for cyclorotor blades, particularly for providing both cyclic and collective pitch control, can be used for any apparatus where dynamic variation of cam controlled movement is needed. The new ring cam has its cam surface on the inside of a ring, the cam surface defining a plurality of different cam profiles which can be dynamically chosen and applied according to need. The different cam profiles are provided by different configurations and by combinations of those configurations. One configuration uses a plurality of adjacent different cam profiles across the inside width of the ring, so that a cam follower follows different cam profiles as it moves across or relative to the cam surface. Another configuration moves a center axis of the ring in relation to the axis of rotation of the cyclorotor, or other rotating device, to dynamically change the effective cam profile. Still another configuration rotates the ring to dynamically change the effective cam profile. The new ring cam assembly includes a cam follower which, for its originally developed use, is operatively interconnected with a cyclorotor blade.
