This report presents a technology warning assessment based on National Academies' methodology. The particular technology area analyzed relates to fully autonomous unmanned aerial vehicles (AUAVs) from the perspective of the United States government with the objective to assess AUAV technology with the goal of strongly enabling, promoting and increasing economic growth. Focus The scope of this r...

This paper describes Microraptor, a complete low-cost autonomous quadrotor system designed for surveillance and reconnaissance applications. The Microraptor ground station is custom-made and features a graphical user interface that presents and allows the manipulation of various flight parameters. The aerial vehicle is a 4-rotor vertical takeoff and landing (VTOL) vehicle that features the adva...

Evaluation of intelligence in Teams of Unmanned Ground Vehicles (UGVs) requires the development of consistent metrics and benchmarks. This is a complicated process as the implementation of the UGVs is problem and domain specific. Different performance requirements give rise to different set of metrics making the comparison of performance between two implementations difficult. In this paper, we ...

This article reports our progress in the developing of a system of cooperative autonomous unmanned aerial vehicles using the Multiagent Systems Engineering (MaSE) methodology. Illustrative fragments of the system models produced during the analysis phase are presented. Some topics of the MaSE methodology are discussed.

A general fuzzy logic control framework along with its application specific modifications is presented to support, evaluate and justify the proposed perspective to unmanned vehicle autonomous navigation. The paper discusses successful applications of collision free motion control of ground, aerial and underwater unmanned vehicles navigation. The common characteristic in all applications regardl...

Project AURORA aims at the development of an unmanned airship capable of autonomous flight over user-defined locations for aerial inspection and imagery acquisition. In this article the authors report a successful autonomous flight achieved through a set of pre-defined points, one of the first of its kind in the literature. The guidance control strategy is based on a path tracking error generat...

Color can be a useful feature in autonomous vehicle systems that are based on machine vision, for tasks such as obstacle detection, lane/road following, and recognition of miscellaneous scene objects. Unfortunately, few existing autonomous vehicle systems use color to its full extent, largely because color-based recognition in outdoor scenes is complicated, and existing color machine vision tec...
