Solar Robo Warbler is a Solar Flapping Wing Air Vehicle (SFWAV). Like most ornithopters (robot birds), this vehicle relies on compliant wing structures that deform the wings while flapping to generate the necessary forces for aerodynamic flight. To make sure the force generated by the wings is enough to maintain flight, the FWAVs are made from lightweight materials to minimize payload. This also limits the onboard energy available for the vehicle resulting in short flights. To extend the flight time of Robo Warbler, flexible solar cells can be introduced throughout the vehicle to harvest energy from the sun while in and out of flight. More energy was harvested for the vehicle allowing for longer flights and for the vehicle ...
