10 April 2023 Intro ROV Contest 2013 1

A national partnership of educational institutions and organizations working to improve marine technical education in the U.S. and to meet the workplace needs of America's marine-related workforce and employers.

10 April 2023 ROV Contest 2012 2

The Marine Advanced Technology Education (MATE) Center

21 regional ROV contests that take place across U.S. and in Canada, Hong Kong, Scotland, Egypt and Japan. Student teams from middle schools, high schools, home schools, community colleges, and universities participate in the events, which consist of different “classes” that vary depending on the sophistication of the ROVs and the mission requirements.

The MATE ROV Competition

Why?

• 2/3 the planet covered by water• We know more about the surface of the moon than

the surface of the earth• 60% of the world’s biomass is under the oceans


Objectives of the contest

• Increase the awareness and visibility of marine technical fields, educational and career opportunities, and potential employers.

• Help students develop the skills necessary to enter careers in technical fields. These skills include the ability to problem solve, think critically, troubleshoot, communicate effectively, and manage projects


Objectives of the contest

• To enhance the awareness of teachers and students to marine conservation and the oceans’ effects on our planet and our lives.

• To provide a platform for design and technology students to partake in a practical design exercise with observable objectives.

• Increase students’ understanding of the role that ROVs play in modern ocean engineering and environmental applications.


The Contest classes

Three ‘classes’ of entry:

Explorer for university, college and high school

Ranger for middle and high school

Scout for elementary/primary school


The missions – from 2006• 2006 Ocean Observing Systems: Tools

for Tomorrow's Science & Technology Workforce (NASA, Houston)

• 2007 Celebrating the International Polar Year: Science & Technology Under the Ice (St Johns, Newfoundland)

• 2008 Diving to the Deep: Uncovering the Mysteries of Mid-Ocean Ridges

(Scripps UCSD, San Diego)• 2009 ROVs: The Next Generation of

Submarine Rescue Vehicles (MMAA, Massachusetts)


The missions – from 2006

• 2010 ROVs in Treacherous Terrain: Science Erupts on Loihi, Hawaii’s

Undersea Volcano (Hilo, Hawaii)• 2011 ROVs: rescuing the oceans; oil spills

and other environmental disasters NASA, Houston)

• 2012 Evaluating World War II shipwrecks and the potentially hazardous material that they may still contain. (Miami, Florida)


2012 contest

2012 contestSurveying and removing hazardous waste from

a WWII shipwreck

Task #1 Survey the shipwreck site

• Measuring the length of the wreck.

• Determining the orientation of the ship on the seafloor.

• Creating a map of the wreck site.

• Determining if debris piles are metal or non-metal.

• Scanning the shipwreck

Task #2: Removing fuel oil from the shipwreck

This mission task involves: • Transporting and attaching a lift bag to a fallen mast.

• Inflating the lift bag to remove the fallen mast from the worksite.

• Removing endangered encrusting coral from the ship’s hull. (2 numbers max)

• Transplanting the coral to the grid (unoccupied square)

2012 contest


• Using two simulated sensors, determine if fuel oil remains inside the fuel tank. • Can combine into 1 sensor• 12cm long & 2cm in dia. (or 2cmx2cm square) • Calibrate it first.• Then place it on the black PVC section.

• Removing a sample of fuel oil from within the tank by drilling a hole into the hull. Returning the sample to the surface.

• Resealing the hole with the magnetic plug.

2012 contest

Engineering & communication scoring - 200 points (max)

Technical reports – 80 points (max)

Engineering evaluations – 80 points (max)

Poster displays – 40 points (max)

And for 2013??????Ocean Observation Systems

MATE have hinted that you should look at

http://www.interactiveoceans.washington.edu/

This is a University of Washington site and we can get some idea of what the contest theme and missions may be from this.


2013………?????????


The OOI Cabled NetworkState-of-the-art instruments cabled to high-power and high-bandwidth networks installed across the seafloor and throughout the water column for interactive studies of the ocean.
