More Details
|
|
SeaBotix pioneered the development
of light-weight, low-cost submersible ROVS (remotely
operated vehicles).

The Challenge
Based in the San Diego Technology
Incubator, Seabotix, Inc. designed, manufactured, and introduced the
first lightweight, low-cost ROV for use at depths of up to 1,500 meters.
The biggest challenge was addressing the temperature changes related
to immersing the unit in frigid sea water after sitting on a boat deck
in the hot sun. The camera has a glass element that has a different
thermal coefficient than aluminum.
The Solution
Stephanie Griffin, a project engineer with Watershot, Inc., a leading
manufacturer of underwater camera housings, consulted on the analysis
portion of the LBV project. Using COSMOSWorks thermal analysis capabilities,
they were able to come up with a functional design, which involved placing
titanium washers between the glass and aluminum end caps.
Summary and Metrics:
- Reduced design cycle by 50 percent
- Minimized tooling modification costs
- Communicated design information among several locations
- Introduced first full-production, light-weight submersible ROV

“Because
COSMOSWorks is integrated with SolidWorks, we could iterate
using email and evolve the design to a state of reliability.
We performed more than 100 design iterations and used eDrawings
to confer with Seabotix on design changes. We are using the
same successful process to complete the 3,000-meter and 6,000-meter
versions of the LBV.�
