Collision avoidance is a key factor in enabling the integration of unmanned aerial vehicle into real life use, whether it is in military or civil application. For a long time there have been a large number of works to address this problem; therefore a comparative summary of them would be desirable. This paper presents a survey on the major collision avoidance systems developed in up to date pub...

The aim of this project was to design and build a test-rig that is capable of analyzing small unmanned aerial vehicles (SUAV) co-axial rotor systems. The intention of the test-rig development was to highlight important aeromechanical components and variables that dictate the co-axial units flight performance, with the intention of optimizing the propulsion systems for use on HALO a co-axial SUA...

This document provides supplementary online material for the paper titled “Evolutionary coordination system for fixed-wing communications unmanned aerial vehicles” recently submitted to TAROS 2014. It mainly focuses on critical system components, namely the aerial vehicles kinematics model, link budget management and also addresses the issue of time synchronisation and algorithmic flow.

Deep sea exploration and exploitation are of an increasingly interest to human beings in the 21 century. Manned and unmanned deep submergence vehicles are necessary means for deep sea explorations. In order to fulfill the requirements of deep sea explorations of COMRA (China Ocean Mineral Resources R&D Association), a deep manned submersible is developed in China and it is now named “Harmony”. ...

This paper presents an algorithm for path planning in which the evasion of fixed and mobile obstacles is considered in order to be followed by an unmanned land vehicle; path planning is based on visual feedback through an unmanned aerial vehicle. In addition, a path planning algorithm is proposed for the ground vehicle in which a non-constant velocity is considered that is a function of the con...

One of the main challenges confronting high-resolution remote sensing image matching is how to address the issue of geometric deformation between images, especially when the images are obtained from different viewpoints. In this paper, a robust matching method for Unmanned Aerial Vehicle images of different viewpoint angles based on regional coherency is proposed. The literature on the geometri...

The feasibility of using a stand alone Fluidic Thrust-Vectoring (FTV) system for the purpose of longitudinal trim of an unmanned aerial vehicle is the focus of the research presented in this paper. Since the fluidic thrust vectoring requires high pressure secondary air to deflect the engine exhaust gases, this research also provides an analytical toolset for preliminary sizing of a suitable sec...

Unmanned Aerial Vehicle (UAV) is a kind of new operational platform possessing ability to flight autonomously and perform independently a task,which can not only carry out non-attack tasks,such as military reconnaissance, surveillance and search, but also to carry out tasks to air-to-ground attacking, target bombing and so on. With the rapid development of UAVtechnology, more and more UAV will ...
