PTEROA150
DEVELOPMENT OF AUV 'PTEROA'
Abstract
A pilot-model vehicle of unmanned untethered AUV (Autonomous
Underwater Vehicle) which can dive to 2000m depth and cruise for
1 hour in 2 knots was constructed in 1989. Free swimming tests in a towing tank started in January of 1990.
On the basis of the experience through the development of
PTEROA150, a prototype vehicle PTEROA250 for 6000m depth dive in 4 knots was designed.
Introduction
In 1984, a research group was organized at the Institute of
Industrial Science, the University of Tokyo to study the next-
decade technology for underwater robotics in the deep sea. Major
fields of research of the members were naval architecture,
hydrodynamics, control, image processing, robotics, structural
strength, aeronautics, and acoustics. Geologist and
oceanographers who are members of Ocean Research Institute of the
University of Tokyo were also invited to this group to discuss
the mission planning.
In 1986, this group was re-organized and 'PTEROA Project'
[1] was started to develop cruising type robots for the survey of
deep-sea bed. The project was funded by the Ministry of
Education and Science of Japan.
The final goal of the project is to develop a prototype
vehicle which can carry out specified measurement during cruising
over the bed; for example, measurement of CTDO and taking
pictures of the bed.
