This paper describes the system design developed for Team Gator Nation’s submission to 2007 DARPA Urban Challenge. A hybrid Toyota Highlander has been automated and instrumented with pose estimation (GPS inertial) object detection (vision ladar) sensors. The control architecture consists of four primary elements, i.e. Planning Element, Perception Intelligence Control Element. Element implements Adaptive Framework by researchers at University Florida. framework provides a means situation...

In this study, we seek to understand how providing feedback users about their performances with an interactive information retrieval (IIR) system impacts evaluations of that system. Sixty subjects completed three recall-based searching tasks experimental IIR and were asked evaluate the after each task finishing all tasks. Before completing final evaluation, three-fourths provided performances. Subjects assigned randomly one four conditions: a baseline condition where no was provided; actual...

The vast majority of Autonomous Ground Vehicles in development today operate with GPS based navigation systems. While the accuracy systems has improved greatly over previous decade, stability their signal not. phenomenon is commonly known as "drift" and may have a magnitude more than few meters. This paper outlines method for vision correction localization vehicle position through consideration priori information perceived road characteristics. approach called Vision Based Position...

This paper presents AUTOTRACKER, an autonomous pipeline inspection system that operates as a dynamic mission payload for Autonomous Underwater Vehicle (AUV). The describes the mode of operation, together with validation & trial operations AUTOTRACKER has undertaken over years, and how this valuable experience been fed back into future development system.

Present generation AUVs act as mobile sensor platforms, allowing post mission debriefs which require little more than an adequate expression of the collected data, and only basic requirements for planning. As need capability advances, autonomy will increase in turn, leading to complex missions, must be supported by capable operator interfaces, both debrief pre-mission verification, lest a deficit trust form between vehicles their operators. We present Glaykos, system designed automatically...
