Abstract
Robotic wings for an aerial drone include a plurality of armwing structures, each comprising a plurality of rigid members connected together by flexible living hinges in a single monolithic structure. Wing membranes are supported by the armwing structures. A drive mechanism is connected to the armwing structures for articulating the armwing structures. A motor is connected to the drive mechanism for actuating the drive mechanism to move the armwing structures through a series of wingbeats wherein the armwing structures expand in a downstroke and retract in an upstroke to move the wing membranes in a flapping motion.

Robotic wings for an aerial drone, comprising:
- a plurality of armwing structures, each comprising a plurality of rigid members connected together by flexible living hinges in a single monolithic structure;
- wing membranes supported by the armwing structures;
- a drive mechanism connected to the armwing structures for articulating the armwing structures;
- each armwing structure including an upper section with a radius four-bar linkage mechanism connected to the drive mechanism and a lower section with a humerus four-bar linkage mechanism connected to the drive mechanism;
- and
- a motor connected to the drive mechanism for actuating the drive mechanism to move the armwing structures through a series of wingbeats wherein the armwing structures expand in a downstroke and retract in an upstroke to move the wing membranes in a flapping motion.
Armwing structures for an aerial robot, each comprising a plurality of rigid members connected together by flexible living hinges in a single monolithic structure,
- each armwing structure supporting a wing membrane and
- articulated by a drive mechanism driven by a motor;
- and
- each armwing structure including an upper section with a radius four-bar linkage mechanism connected to the drive mechanism and a lower section with a humerus four-bar linkage mechanism connected to the drive mechanism,
- such that the armwing structures are moved through a series of wingbeats during which the armwing structures expand in a downstroke and retract in an upstroke to move the wing membranes in a flapping motion.
