As one of the most important components of a flapping-wing micro air vehicle (FWMAV), the design of an energy-efficient flapping-wing has been a research interest recently. Research on insect flight from different perspectives has been carried out, mainly with regard to wing morphology, flapping kinematics, and unsteady aerodynamics. However,...

This paper presents an overview of the Paparazzi UAV system and its recent use in scientific research. Paparazzi is an open-source project that aims at providing a complete solution to fly fixedwing aircraft and rotorcrafts. Several hardware boards and sensors are also developed within the project. Since several years, it has been used by...

Creating an autonomous flying vehicle the size of a honeybee presents a number of technical challenges because of its small scale. As vehicle wingspan diminishes, angular acceleration rates increase, necessitating sensing and control systems with high bandwidth. Hovering demonstrations have so far required feedback from highspeed motion capture...

Recent advances in sensor miniaturization have enabled the development of a miniaturized fully functional autopilot. In this article, the open hardware and open software Paparazzi-UAV Lisa-S micro autopilot is presented, weighing only 2.8 grams and measuring 2 by 2 centimeters. It incorporates 2-way telemetry with a ground station, a Spektrum...

This paper describes the design, build and fly University of Glasgow Singapore (UGS) flapping wing MAVs using fabrication method such as laser cutting and Rapid Prototyping. The first prototype was made from acrylic using a laser cutting machine. The material was strong however it was brittle. The wings were made up of carbon rods and kite...

The IMAV2014 Competition gives an important place to computer vision and aerial mapping. This paper presents the different strategies and algorithms that have been developed in order to tackle these particular problems. The first task consists in automatically reading the digit displayed by a seven segment panel on the front wall of a building....

The design of a relatively new genre of aerial robots—a full-scale, bird-like flapping wing flying robot—is analyzed, modelled and validated through real experiments in this paper. Quaternions are used instead of Euler angles in the dynamical model to represent the flying robot orientation in 3D space in order to realize smoother rotational...

Micro Air Vehicles (MAVs) are small unmanned aircrafts which have a maximum size limit of 150 mm in any direction. They can be used for surveillance, reconnaissance, targeting, etc. To perform such missions, MAVs are required to hover. Hummingbirds, having excellent flight characteristics (such as hovering, ability to fly in any direction,...

This paper presents the results of a series of flight tests conducted in order to assess the steady-state flight characteristics and basic control behaviour of the DelFly, a flapping-wing micro aerial vehicle (FWMAV). Flights were conducted in an indoor motion tracking facility and included steady-level flight at a range of different velocities...

The concept of an aircraft capable of both hover as well as fast forward flight (hybrid) has recently been implemented on unmanned aerial vehicles (UAV). Hybrid UAVs combine hover capability with long range and endurance. As UAVs are often required to operate without human intervention, there is a call for autonomous guidance of hybrid UAVs....

Micro Aerial Vehicles (MAVs) are small unmanned aerial vehicles (UAVs) that are generally equipped with camera, GPS and other sensors and are envisioned for many civil and commercial applications. Some of these applications require transmitting multimedia traffic and demand for a high wireless network throughput. In this paper, we consider an...

We present our insect-based hovering Flapping-Wing Micro Air Vehicle (FW-MAV) capable of sustained flight and control. The proposed design combines two fixed wings and two flapping wings to take advantage of the double clap-and-ling effects at the end of each half-stroke during one flapping cycle for high thrust production, and utilizes the...

A dynamic model of an insect wing is developed treating the wing as a deformable body subject to three-dimensional finite rotation about a fixed point at the base of the wing. Discretization of a stationary wing is conducted via finite element analysis to determine the natural frequencies and mode shapes of the wing. By formulating and...

In this paper the problem of estimation and correction of wind effects on a quadrotor UAV, without using wind sensors, is discussed. A large body of research addresses the effects of wind on a quadrotor, however most of them consider it only as a disturbance in their control loop and, for this reason, they solved the problem compensating for the...

Flapping wing micro air vehicles (MAVs) have the advantage of being able to fly at slow speeds and have high maneuverability. The design of a flapping wing MAV inspired by birds presents many technical challenges because birds as natural fliers exhibit higher efficiency than any man made flapping wing structure. Thus, the structure and motion of...

This paper addresses the unsteady aerodynamic mechanisms in the hovering flight of the DelFly II flapping-wing Micro Aerial Vehicle (MAV). Stereoscopic Particle Image Velocimetry (Stereo-PIV) were carried out around the wings at a high framing rate. Thrust-force was measured to investigate the relation between the vortex dynamics and the...

This paper proposes a method to detect dynamic objects in the images obtained by a small UAV. Two geometric constraints in multi-view images are used to classify each of the extracted featurepoints as static or dynamic. The first constraint is the epipolar constraint which requires static points to lie on the corresponding epipolar lines in the...

For Micro Aerial Vehicles (MAVs), robust obstacle avoidance during flight is a challenging problem because only light weight sensors as monocular cameras can be mounted as payload. With monocular cameras depth perception cannot be estimated from a single view, which means that information has to be estimated by combining images from multiple...
