Abstract
In this work a forest fire detection solution using small autonomous aerial vehicles is proposed. The FALCOS unmanned aerial vehicle developed for remote-monitoring purposes is described. This is a small size UAV with onboard vision processing and autonomous flight capabilities. A set of custom developed navigation sensors was developed for the vehicle. Fire detection is performed through the use of low cost digital cameras and near-infrared sensors. Test results for navigation and ignition detection in real scenario are presented.

Abstract
This paper describes the design and implementation status of the Control and Localisation systems of the ISePorto robotic football team for participation in Robocup Middle Size League (F2000). The objectives guiding the project were the applications and research in hybrid control and coordination systems. The system has also an educational support role. 4 special attention is made to the custom design to allow the execution of complex manoeuvres and team coordinated behaviours. The robot has different pass, shot, and manoeuvre capabilities providing high level tactical and strategic planing and coordination.

Abstract
System and mission requirements for the use of Autonomous Underwater Vehicles (AUV) were defined. A requirement analysis was done having in mind the definition of search methodologies involving multiple cooperating vehicles. Control and navigation issues were addressed. Various search strategies were proposed and analyzed in terms of control, navigation and overall system requirements.

Abstract
This work presents a hybrid maneuver for gradient search with multiple AUV's. The mission consists in following a gradient field in order to locate the source of a hydrothermal vent or underwater freshwater source. The formation gradient search exploits the environment structuring by the phenomena to be studied. The ingredients for coordination are the payload data collected by each vehicle and their knowledge of the behaviour of other vehicles and detected formation distortions. Copyright © 2004 IFAC.

Abstract
This paper presents a conceptual architecture for the control of multiple autonomous underwater vehicles based on the concept of Generalized Vehicle. The design of this architecture was driven by requirements extracted from the analysis of operational scenarios involving the operation of multiple vehicles and embodies an extension of the Dynamically Reconfigurable Control Architecture for an AUV proposed by the authors in previous published work.
