At Sea Trial Agenda

October2002 - december 2003: Integration and tests of the software modules Global verification Tests in ROV configuration

January - february 2004 Autonomous mission

Non Traditional Navigation UUV Guidance and Non Traditional Navigation UUV Guidance and Control Research ProjectControl Research Project

Main GoalMain Goal

Main objectives :– Precise navigation (for drift limitation) by sonar and inertial data fusion ;– Development of high level functions : image processing, mapping and localization, mission

planning and control ;– Hardware and software Integration for at sea demonstration.

Final Demonstration :To rally different mission areas for operation achievement

To use sonars for mapping and localization

Development of Generic Tools for underwater mobile robots

General System ArchitectureGeneral System Architecture

Perception environment,

internal

Decision Action planning,

guidance, control / command

Functionalities:

- are activated by messages (requests)

- send back messages (events)

- exchange data through shared memory

Execution Monitoring

send requests when events occur

according with Behaviors specifications.

REQUEST

ProCoSA = programming and execution monitoring of autonomous systems (® ONERA)

EdiPet : graphic user interface for Petri nets generation (places for behavioral state, transitions for actions, events for messages)

JdP : Petri player automata (LISP) to run the system VisuPet: possible display of the behavior states during mission execution

added value : integration of independent sub-systems, behavior specification

identical to execution monitoring

event + information

actions = request for computation towardsservers (sockets)
