Exploratory Bird

The purpose of this design was to test the basic compliant mechanism concept and the weight distribution that leads to sustained flapping wing flight.

Weight: 8.3 g  (including battery)
Wing Span: 33.1 cm
Pay Load Capability: 0 g

Big Bird
This was our attempt at increasing the payload of the bird to carry on-board sensors.
Weight: 27.9 g (excluding battery)
Wing Span: 57.2 cm
Flapping Frequency:  4.5 Hz
Pay Load Capaility: 19.1 g (including battery)

Big Bird with Vision
We used the payload capacity of the big bird  to attach a video camera with radio transmitter to get images as seen by the bird.
Weight: 42.2 g (including battery and video camera)
Wing Span: 57.2 cm
Flapping Frequency:  4.5 Hz

Big Bird with Folding Wing

By mimicking the folding of the bird’s wing, we slowed the flight velocity by 10% without any appreciable decrease in the overall weight of the bird in flight (this included weight of the bird and the payload).

Weight: 29.9 g (excluding battery)
Wing Span: 57.2 cm
Flapping Frequency:  4.5 Hz
Pay Load Capability: 17.0 g (including battery)

Jumbo Bird
This was our attempt at further increasing the payload of the bird to fly with an auto pilot. Weight: 38.0 g (excluding battery)
Wing Span: 63.5 cm
Flapping Frequency:  6.1 Hz
Pay Load Capability: 33.0 g (including battery)
