As underwater research platforms, MBARIs ROVs are among the best in the
world. Meeting the challenge to continue cutting-edge scientific work requires continual
upgrading of equipment and innovative technology.
P9A Upgrades to Tiburon
Objectives for Tiburon in 1998 generally involve increasing the
operational utility of existing vehicle systems and implementing new, mission-specific
toolsleds. The tasks include:
Technicians are installing a manipulator arm on the core
vehicle. Attached to the core, it will be available on every dive and complemented on
specific missions by the existing arm mounted on the toolsled.
Engineers will complete and deploy a midwater toolsled for Tiburon
that will include detritus samplers, electrically controlled swing arms, and a
carousel-type suction sampler.
A benthic biology toolsled will be designed, fabricated, and
The prototype benthic toolsled is being upgraded to an
operational seafloor geology unit.
- Documentation Technicians are working to remedy remaining
operational problems on Tiburon and MBARIs technical writer is continuing
documentation efforts for each system.
- Navigation system Under the robotics research project, a
collaboration with students from Stanford University's Aerospace Robotics Laboratory,,
engineers are designing and implementing a three-dimensionally aided, inertial navigation
system. The system would calculate estimations of position from multiple sensor inputs.
Such estimations provide more accurate and timely position-related information than those
determined by the existing acoustic positioning system alone. This additional degree of
precision would allow researchers to use applications that depend on recorded geographic
and positioning data for fine-scale surveying.
P9A Upgrades to Ventana
Changes slated for Ventana include:
Engineers will upgrade the fiber-optic housing for the R/V Point Lobos/Ventana tether.
Engineers will complete implementation of a navigation
system that will be comparable to, and compatible with, the Tiburon/R/V Western Flyer system.
