4 NE03 ROV Competition Held at Cambridge Rindge and Latin School, Boston, MA 13 competing teams Mission was to collect C-Probes out of a mock-up of the Titanic wreck Titanic mock-up used for NE03 competition C-Probe schematic

5 NE04 ROV Competition Will be held at URI s Tootell Aquatic Center on May 8 th, 2004 Currently ~10 teams registered Competition scenario: Explore Mystery Reef and perform seven marine science and recovery mission tasks within 25 minutes

6 Competition Scoring Pool Mission Score: 100 Points Engineering and Communication: 110 Points Engineering: 80 Points Technical Report: 20 Points Poster: 10 Points Total Possible Score: 210 Points

7 Pool Mission: Mystery Reef Construction: ½ PVC tubing frame, black plastic cover Reef will stand no more than 4 feet off of the bottom Exact layout of the reef will remain unknown until competition

8 U-Boat Mockup *This U-Boat design has been slightly modified; the stern section is smaller than shown in this drawing

9 Competition Layout General layout of the Tootell Aquatic Center for NE04

10 Mystery Reef: Mission Tasks Task 1: Find and recover sidescan sonar towfish Task 2: Find and identify the Captain s Bell Task 3: Simulate patching a leaking barrel Task 4: Find and collect all five of a T.B.A. species of fish from the reef Task 5: Find the source of the methane and tag the tubeworm cluster next to it Task 6: Find and tag the mussel bed Task 7: Find the authigenic carbonate formation and bring back 5 samples

11 Mission Tasks: A Closer Look Task 1: Find and recover the sidescan sonar towfish A model of a sidescan sonar towfish (1 m in length) will be placed in a random location along the reef. Using a length of poly line, hook onto the sidescan s U-bracket and then pull up the model. Weight in air: 1 kg

Mission Tasks: A Closer Look (cont.) Task 2: Find and identify the Captain s Bell The captain s bell will be located in the front compartment of the U-Boat wreck.

12 Mission Tasks: A Closer Look (cont.) Task 2: Find and identify the Captain s Bell The captain s bell will be located in the front compartment of the U-Boat wreck. The ROV must locate the bell and correctly read the inscribed message. Task 3: Simulate patching a leaking barrel The ROV must search the reef for a leaking barrel - a 1-gallon paint can with a black spot on its upper surface. Once found, the vehicle must place a patch over the black spot.

Mission Tasks: A Closer Look (cont.) Task 4: Find and collect all five of a T.B.A. species of fish from the reef Five species of fish : five per species = a total of 25 fish scattered among the reef.

13 Mission Tasks: A Closer Look (cont.) Task 4: Find and collect all five of a T.B.A. species of fish from the reef Five species of fish : five per species = a total of 25 fish scattered among the reef. The judges will name a single species for each team to find. The ROV must find these five specific fish and move them into a collection basket, where they can be brought to the surface.

14 Mission Tasks: A Closer Look (cont) Task 5: Find the source of the methane and tag the tubeworm cluster next to it The vehicle must identify the location of the tubeworm cluster and drop a tag onto it. The cluster can be found by looking for methane bubbles - a stream of air bubbles located directly adjacent to the bed. Task 6: Find and tag the mussel bed Same as Task 5, without the bubbles.

15 Mission Tasks: A Closer Look (cont.) Task 7: Find the authigenic carbonate formation and bring back 5 samples The ROV must find the pile of authigenic carbonate- small pieces of lava rock (pumice)- and retrieve 5 samples to be brought to the surface.

16 Educational Benefits Advanced introduction to robotics and marine technology Team project skills Competition is an exercise for marine biology/archeology units Technical writing The North Kingstown (RI) ROV team (2003)

Technical Challenges Some kind of manipulator or arm to lift objects/ deliver tags Visual identification/ observation Speed and mobility Variable

17 Technical Challenges Some kind of manipulator or arm to lift objects/ deliver tags Visual identification/ observation Speed and mobility Variable ballast or thruster compensation for payload Sealed vs. unsealed motors Carl Hayden High School s (CA) ROV entry for 2003, undergoing sea trials last year
