This article presents the development of a visionbased VTOL UAV docking system for outdoor applications. A new marker type is constructed, along with a robust detection algorithm based on the Hough transform, which forms the basis of the positioning system. For verification purposes, a binary classifier based on support vector machines is...

This research employs ecological interface design to improve the human machine interface of an existing ground control station for the supervisory control of UAV swarms. As a case study, a general ground surveillance mission with four UAVs is envisioned. An analysis of the swarming work domain is performed to generate a reduced set of means-end...

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...

In this paper, a steady 3D numerical study has been conducted on a 90 mm counter rotating lift fan to investigate its aerodynamic performance. The effect of axial distance between the fans and rotor speed are studied. A low thrust generation has been revealed from the simulation results due to the unfavourable working condition for the upstream...

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 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...

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...

MAV (Micro Aerial Vehicle) systems have proven useful in multiple applications (e.g. aerial photogrammetry, aerial inspections,...). For each application different sensors and even different airframes are often needed. Having a flexible UAS (Unmanned Aircraft System) devices (specifically an autopilot, a payload manager and a ground control...

Hovering flapping flight is inherently unstable and needs to be stabilized actively. We present a control mechanism that modulates independently the wing flapping amplitude and offset by displacing joints of a flapping linkage mechanism. We demonstrate its performance by high speed camera recordings of the wing motion as well as by direct...

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,...

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....

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...
