Achievements to date Publications: 6 Internal Reports, Seminar Talks Workshops & conferences: NGCUV ‘ 08 Participation in tests: GREX Azores ‘ 08 Secondments: NTNU Norway, Fall ‘ 09 Training: Lectures on Dynamical Linear ahaeusler@isr. ist. utl. pt

Technical Summary The Problem l Multiple vehicle missions require the vehicles to be in formation l An initial formation has to be established before the mission starts l Vehicles cannot be deployed in formation ðNeed to get the vehicles into initial formation ahaeusler@isr. ist. utl. pt

Technical Summary The solution Rigorous solution based on optimization techniques and a new polynomial path parametrization: Simultaneous arrival at designated positions and orientations Avoid collisions until mission control takes over Consider time, energy and vehicle constraints ahaeusler@isr. ist. utl. pt

Coordinated Target Tracking Moving Target Sonar, GPS, acoustic data Leading pursuer Data Smoothing Cooperative Path Following Path Sequence Path Fitting ahaeusler@isr. ist. utl. pt

Technical Summary Related Work within FREEsub. NET l How do we deal with “deviations from the plan”? (wind, currents, etc. ) ðUse cooperative path following! (Methods are available – IST, NTNU) First Results (see the video) LINK TO THE VIDEO ahaeusler@isr. ist. utl. pt
