ROAZ and ROAZ II Autonomous Surface Vehicle Design and Implementation
International Lifesaving Congress 2007, La Coruna, Spain, December, 2007The design and implementation of the ROAZ and
ROAZ II autonomous surface vehicles (ASV) is presented. These
systems were developed at Autonomous Systems Lab, ISEP/IPP –
Instituto Superior de Engenharia do Porto under a research
program in marine robotics. With multiple applications either in
river and estuarine environments or in the sea, the system
applications in search and rescue operations are addressed and
were taken in consideration for the overall system design.
Mechanical design issues are discussed. Hardware, software
and implementation status are described along with the control
and navigation system architecture. The real time vision
processing system is described and results are presented in
operational scenario
ROAZ Autonomous Surface Vehicle Design and Implementation
The design of an Autonomous Surface Vehicle for operation in river and
estuarine scenarios is presented. Multiple operations with autonomous underwater
vehicles and support to AUV missions are one of the main design goals in the ROAZ
system. The mechanical design issues are discussed. Hardware, software and
implementation status are described along with the control and navigation system
architecture. Some preliminary test results concerning a custom developed thruster are
presented along with hydrodynamic drag calculations by the use of computer fluid
dynamic methods
