63. Multiple UAV teams for multiple tasks - Sujit Baliyarasimhuni; João B. Sousa; F. Lobo Pereira
In a search and prosecute mission, multiple heterogeneous unmanned aerial vehicles UAVs that carry different resources need to perform the classify, prosecute and battle damage assessment (BDA) tasks on targets sequentially. Depending on the target resource requirement, it may be necessary to deploy a coalition of UAVs to perform the action. In this paper, we propose coalition formation algorithms that have low computational overhead to determine coalitions for the prosecute and the BDA tasks. We also develop a simultaneous strike mechanism based on Dubins curves for the UAVs to prosecute the target simultaneously. Monte-Carlo simulation results are presented to show...

68. A set-valued framework for coordinated motion control of networked vehicles - João Tasso Sousa; Fernando Lobo Pereira
A problem of coordinated control for two networked vehicles is presented, formulated, and solved to illustrate a set-valued framework for the coordinated control of networked vehicles. First, an informal user specification for the coordinated operation of two vehicles is introduced. Second, a formal representation of the objects and relations of interest is presented, and the user requirements are mapped onto a formal specification. Third, the specification is transformed onto a control problem formulation. Finally, the problem is solved using techniques from dynamic optimization and generalizations of the problem are discussed. © Nauka/Interperiodica 2006.

72. Video summary - Neptus, command and control infrastructure for heterogeneous teams of autonomous vehicles - Paulo Sousa Dias; José Queirós Pinto; Rui Gomes; Gil Manuel Gonçalves; João Tasso Sousa; Fernando Lobo Pereira
This video shows a brief overview over Neptus, a command and control infrastructure for heterogeneous teams of autonomous vehicles. Having different types of vehicles at our laboratory and from our partners, there was an increasing need to create a common infrastructure to all these systems. Additionally, a tool to support the entire mission life cycle (Planning, Execution, Review and Dissemination) was lacking. Neptus was created to provide vehicle independence and seamless inter-systems communications. Currently, Neptus has been already tested with Remotely Operated Vehicles, Autonomous Underwater Vehicles, Unmanned Air Vehicles, Autonomous Surface Vehicles and Wireless Sensor Networks. Some of these systems...
