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.


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.


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.


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.21 April 2023 Intro ROV Contest Briefing 2016 7

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.


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.


The Contest classesThree ‘classes’ of entry:

Explorer for university, college and high school – qualifies for International ROV ContestRanger for high school – top 2 HKG teams qualify for

International ROV ContestAdventurer for junior high schoolH K Scout for elementary/primary school

Explorer and Ranger follow MATE rules; Adventurer and HK Scout do not.

2016 missionsEXPLORER and RANGER Outer Space: Mission to Europa • Measure the temperature of venting fluid. • Determine the thickness of the ice crust using pressure

measurements. • Determine the depth of the ocean under the ice using pressure

measurements. • Connect the Environmental Sample Processor (ESP) to the

power and communications hub: o Retrieve the ESP’s cable connector from the elevator.

• Lay the ESP cable through three waypoints. • Open the door to the port on the power and communications hub. • Insert the cable connector into the port on the power and

communications hub.


2016 missions


EXPLORER and RANGER

Inner Space: Mission-critical equipment recovery • Survey the seafloor to find and identify mission-critical NASA

equipment. • Place the equipment in a collection basket for retrieval by a

crane at the surface.

Inner Space: Forensic Fingerprinting • Collect and return two oil samples to the surface. • Analyse a gas chromatograph of each sample to determine its

origin.

2016 missionsEXPLORER and RANGER

Inner Space: Deepwater Coral Study • Photograph corals and compare the images to previous years

to assess their condition. • Collect coral samples and return them to the surface for

analysis. Inner Space: Rigs to reefs • Attach a flange to the top of the wellhead. • Secure the flange to the wellhead with one bolt. • Install a cap over the flange. • Secure the cap to the flange with two bolts.


2016 missions


ADVENTURERMarine Debris(Collect and return to the surface)• One crushed and one whole soda tin from the seabed.• Two plastic bags from the seabed• Two plastic bottles from the seabed• Two pieces of ghosted fishing nets• Scientific Data Collection• Retrieve an existing temperature data logger and deploy a

new one.• Collect six coral samples for analysis at the surface.• Collect two crabs for analysis at the surface.

2016 missions

HK SCOUTScientific Data Collection•Collect corals for analysis at the surface.•Collect crabs for analysis at the surface.•Collect sea stars for analysis at the surface.•Collect sea urchins for analysis at the surface.•Collect fish for analysis at the surface.

The IET HK ROV kit

• Based around 16mm pvc tubing• Uses 3 bilge pump motors with impellors removed

and replaced with propellers• Uses two cistern floats for buoyancy• 3 5m lengths of speaker wire to get power to

motors• 3 sprung mid-position DPDT switches to control

motor direction• No soldering necessary – all wire joints crimped

The Basic ROV Workshop

• Check all parts are in your box/on the workbench. Use the parts checklist.

• Split into two groups; • Electrical group• Frame group



Frame group: a.cut up plastic pipe as indicated:

i. 5 pieces – 150 mmii. 2 pieces – 75 mmiii. 2 pieces – 135 mm

b.Use a small saw and the vice on the table.c.Make sure the L joints with the holes are at the topd.Assemble, without gluing, following frame on displaye.Mark and drill holes, 4mm, to hold motor clamps



Electrical group: a.Split into two groups:

i. Umbilical groupii. Switch box group

b.Umbilical group: cut the long 16 m wirei. Cut 1m for power connection cableii. Cut the remaining wire into 3 equal lengths (approx 5m –

don’t measure!)

c.Switch box group: wire up switch box as shown in the diagram. Use unit on display as a guide



Finally:

•Connect umbilical to frame and switch box•Test all electrical connections (keep fingers away from propellers•Glue frame and use cable ties to tidy up umbilical and provide tensioner at the frame•Test in water tank
