Abstract
A flapping wing device may include a main body and several wings hingedly coupled to the main body. The wings may be configured to reciprocate or “flap” relative to the main body to provide lift for the flapping wing device. A motor and trans mission, such as a crankshaft, are used to drive the reciprocating motion of the wings. The wings reciprocate from a first position that is substantially vertically parallel to the main body of the device to a second position in which a second end, opposite the hinged end, extends away from the main body. The motion of the reciprocating wings may be reminiscent of the motion of a jellyfish. In some instances, a first set of opposing or alternating wings may be reciprocated at an offset period relative to a second set of opposing or alternating wings, such as a quarter period offset.
