Autonomous Vertical Recovery of Fixed Wing Unmanned Aerial Vehicles

Autonomous Recovery of a Fixed-Wing UAV Using a Net Suspended by Two Multirotor UAVs

This article presents a novel recovery method for fixed-wing Unmanned Aerial Vehicles (UAVs), aimed at enabling operations from marine vessels. Instead of using the conventional method of using a fixed net on the ship deck, we propose to suspend a net under two cooperative multirotor UAVs. While keeping their relative formation, the multirotor UAVs are able to intercept the incoming fixed-wing ...

Flight Results of Autonomous Airplane Transitions to and from Vertical Hover

Fixed-wing unmanned aerial vehicles (UAVs) with the ability to hover have significant potential for applications in urban or other constrained environments where the combination of fast speed, endurance, and stable hovering flight can provide strategic advantages. This paper discusses the use of dynamic inversion with neural network adaptation to provide an adaptive controller capable of transi...

Autonomous Search and Surveillance with Small Fixed Wing Aircraft by Timothy Garland McGee Doctor of Philosophy in Engineering-Mechanical Engineering University of California, Berkeley Professor J. Karl Hedrick, Chair Small unmanned aerial vehicles (UAVs) have the potential to act as low cost tools in a variety of both civilian and military applications including traffic monitoring, border patr...

A Feasibility-study of a Micro- Communications Sonobuoy Deployable by UAV Robots

This paper describes a feasibility study that is included with the research, development and testing of a micro communications sonobuoy deployable by Maritime Fixed wing Unmanned Aerial Vehicles (M-UAV) and rotor wing Quad Copters which are both currently being developed by the University of Adelaide. The micro communications sonobuoy is developed to act as a seamless communication relay betwee...
