Robo Raven II optimizes the design of flapping wing air vehicles by studying the subsystems. By optimizing their combined functionality, design objectives are reached and performance is improved. Key design parameters (flapping gait, wing size, motors) are always interacting and must be considered together. Appropriate selection of each of these allows challenging flights in cold weather.
This test flight was filmed by a quadcopter. The outside temperature was 10 degrees Fahrenheit.
