This paper describes recent results on the design and simulation of a flight control strategy for the Micromechanical Flying Insect (MFI), a 10-25mm (wingtipto-wingtip) device capable of sustained autonomous flight. Biologically inspired by the real insect’s flight maneuver, position control is achieved via attitude control. The wings motion is parameterized by a small set of parameters which a...

conclusions: thus, identifying the hf patients before the flight and providing them proper education about the events that may occur during flight is necessary. results: hf patients are more prone to experience respiratory distress, anxiety, stress, cardiac decompensation, and venous thromboembolism (vte) during air travel. although stable hf patients can tolerate air travel, but those with acu...

Bumblebee foragers spend a significant portion of their lives transporting nectar and pollen, often carrying loads equivalent to more than half their body mass. Whereas nectar is stored in the abdomen near the bee's center of mass, pollen is carried on the hind legs, farther from the center of mass. We examine how load position changes the rotational moment of inertia in bumblebees and whether ...

Just as the Wright brothers implemented controls to achieve stable airplane flight, flying insects have evolved behavioral strategies that ensure recovery from flight disturbances. Pioneering studies performed on tethered and dissected insects demonstrate that the sensory, neurological, and musculoskeletal systems play important roles in flight control. Such studies, however, cannot produce an ...

For flight control of helicopter UAVs, it is essential to have high-quality 6-DOF attitude measurements. In the course of the miniaturization, the need for reliable orientation sensors conflicts with strict resource constraints. This paper presents the algorithms for orientation calculation used on-board TU Berlin’s helicopter UAV MARVIN as an example of “low-resource” orientation measurement. ...
