A standard intelligent system ontology

Abstract: The level of automation in combat vehicles being developed for the Army's objective force is greatly increased over the Army's legacy force. This automation is taking many forms in emerging vehicles; varying from operator decision aides to fully autonomous unmanned systems. The development of these intelligent vehicles requires a thorough understanding of all of the intelligent behavior that needs to be exhibited by the system so that designers can allocate functionality to humans and/or machines. Traditional system specification techniques focused heavily on the functional description of the major systems and implicitly assumed that a well-trained crew would operate these systems in a manner to accomplish the tactical mission assigned to the vehicle. In order to allocate some or all of these intelligent behaviors to machines in future vehicles it is necessary to be able to identify and describe these intelligent behaviors in detail. In this paper, we describe an effort to develop an intelligent systems (IS) ontology using Protege. The goal of this effort is to develop a common, implementation-independent, extendable knowledge source for researchers and developers in the intelligent vehicle community that will: * Provide a standard set of domain concepts along with their attributes and inter-relations * Allow for knowledge capture and reuse * Facilitate systems specification, design, and integration, and * Accelerate research in the field. This paper describes the methodology we have used to identify knowledge in this domain and an approach to capture and visualize the knowledge in the ontology.

Injecting inter-autonomous system routes into intra-autonomous system routing: a performance analysis

Abstract: The current TCP/IP Internet may be modeled as an arbitrary interconnection of autonomous systems 1 ( [Honig 90]) . Routing in the Interne t is partitioned into intra-autonomous system routing (intra.-S routing) an d inter-autonomous system routing (inter-AS routing) . If both a source and a destination belong to the same AS . then routing between the source and th e destination is completely realized by employing intra-AS routing procedure s used by the AS . However . if a source and a destination belong to differen t ASs . then routing between the source and the destination cannot be realized either completely within the inter-AS routing or completely within th e intra-AS routing . but involves both the intra and inter-AS routing . That . i n turn, requires a certain degree of interaction between the intra and inter-A S routing procedures .

Design, modelling and simulation of an autonomous underwater vehicle

Abstract: This paper describes the design and modelling of an Autonomous Underwater Vehicle (AUV), together with a simulation system for AUVs with arbitrary propulsion and sensor systems. The use of a simulation system allows to rapidly test AUV designs, e.g. different propulsion systems or different sensor configurations. Different AUV designs can be compared with their suitability for a given task before they even have been built. Therefore, the use of a simulation system can advance and speed up the design process of an AUV.

Autonomous welding of large steel fabrications

Abstract: Purpose – Development and demonstration of an autonomous, mobile welding robot capable of fabricating large‐scale customised structures. Design/methodology/approach – An autonomous welding robot has been developed under the EC Framework V Growth program. The system comprises a global vision system for part location and orientation, and a robot transport vehicle (RTV) which carries a 6‐axis robot, robot controller, welding equipment, and local sensors at the welding torch. The RTV path, robot arm motion and weld process programming are performed automatically using sensors and specially customised simulation software. Findings – The technology developed within the project was demonstrated, in November 2004, to be capable of identifying and welding large scale customised structures as found in the earth moving equipment and bridge fabrication industries. Research limitations/implications – The project demonstrated that current sensor technology is capable of being applied successfully to autonomous robots, but further developments in sensor technology are required to improve accuracy and joint access. Practical implications – The NOMAD concept of autonomous mobile robots provides an alternative solution to welding mass customised structures. Originality/value – This project demonstrated, for the first time, the capability of autonomous robots to weld large scale customised structures.
