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.

An ornithopter aircraft has a main body. A first wing frame mount and a second wing frame mount are mounted to the main body. A first wing frame is rotably mounted to a first wing frame axle on the first wing frame mount. The first wing frame is configured to rotate relative to the main body and the rotation can be powered. The first wing frame feathers are rotably mounted to the first wing frame at first feather axles and the first wing frame feather rotation can be powered. The first wing frame feathers are configured to rotate relative to the first wing frame and the first wing frame feather rotation can be powered. A second wing frame is configured to be rotably mounted to a second wing frame axle on the second wing frame mount.

The invention relates to a flight system having at least two actuated flapping wings (2), an actuated tail unit (9), a control device and an exoskeleton (1) for at least one person. The exoskeleton (1) is movable independently of the flapping wings (2). The control device is configured to receive motion sensor signals from the exoskeleton (1) and to use the motion sensor signals to define specified movement signals and to control the flapping wings (2) and/or the tail unit (9) by way of the specified movement signals. The specified movement signals can be defined such that the movements of the flapping wings (2) and/or of the tail unit (9) follow those of the exoskeleton (1).
