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. 22 January 2016Intro ROV Contest Briefing 20163

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. 22 January 2016Intro ROV Contest Briefing The Marine Advanced Technology Education (MATE) Center

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. 22 January 2016Intro ROV Contest Briefing 20165

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 22 January 2016Intro ROV Contest Briefing 20166

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. 22 January 2016Intro ROV Contest Briefing 20167

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. 22 January 2016Intro ROV Contest Briefing 20169
