The IET Hong Kong
The Institution of Engineering and Technology
(IET) is the largest professional engineering
institution in Europe with around 250,000
members worldwide. It is the largest body
awarding professional engineer recognition. The
IET Hong Kong is the largest branch of the IET
outside the UK, with over 5,000 members.

The Marine Advanced Technology
Education (MATE) Center
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.

24 regional ROV contests that take place across U.S. and in
Canada, as well as countries like 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.

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

Competition Philosophy
The ROV competition is about student learning. It is
designed to be an event that challenges students to
apply the physics, math, electronics, and engineering
skills they are learning in the classroom to solving
problems from the marine workplace. Mentors
(teachers, parents, working professionals) are expected
to limit their input to educational and inspirational
roles and encouraged to focus on the benefits of the
learning process and not simply on “winning” the
competition.
