IMPORTANT FORUM RULINGS

Post by Matthew Gardner » Mon Feb 25, 2019 10:59 am

Hi 2019 Competitors:

Below are some important rulings that have been made from questions on this board. I wanted to summarize them here so you do not need to dig through 100 posts to find an answer.

If you have further questions about a ruling, please post the question in a separate thread.

Thank you.

EXPLORER class companies locating and gathering information about the length of the crack in a fully autonomous manner (concurrent with autonomous line following) may not touch a button or manipulate controls to take a screen shot of the crack to be sent to another device. To receive 25 points for locating and autonomous determination of length of crack concurrent with autonomous line following, the entire procedure must be completely hands free. Contradictory information given in the EXPLORER Facebook Live is INCORRECT. The MATE Center judge group has ruled that to receive the maximum points, the entire operation must be completely hands free. Companies that need to hit a button or push controls to take a screenshot and send it to another device would fall under the category of Locating and autonomous determination of length of crack with manual control.

Companies (RANGER and EXPLORER) undertaking image recognition of benthic species are allowed minimal hands on activity to capture an image and send it to another device for image processing and identification. Prior to setting up at the product demonstration station, when the station judges greet the company, the CEO or other member of the company should inform the judge they will be taking a screen capture of the benthic images to send to another device. The company members MUST detail the buttons / devices they will need to touch to capture this image during this discussion. During the product demonstration time, the company should communicate with the station judges, letting them know that they are about to go “hand’s on” to take a screen shot and transfer it to another device. Company members should remind the judges of what actions will be undertaken to do this screen grab and transfer. Failure to communicate with the judges could lead to the company not being allowed to use image recognition.

Companies ARE REQUIRED to note the screen capture and procedure (what buttons are pushed / devices used ) in their image recognition documentation. If the procedure is not noted in the documentation, companies will not be allowed to capture and transfer the image.

-----------------------

When the micro-ROV is attached to, or docked with, the primary ROV, companies may use its camera (and thrusters) normally, and could complete other tasks (visual tasks) using the micro-ROV camera. If the micro-ROV is in the water and not docked with/attached to the primary ROV, you cannot complete any tasks other than the internal pipeline inspection. The micro ROV must be docked with/attached to the primary ROV, or removed from the primary ROV and on the surface, to complete any other task.

-----------------------

Companies may run their micro-ROV tether directly from the surface and through the ROV with no direct connection points. I.e. RANGER companies may use an extra set of conductors going down with main tether and out to micro-ROV. EXPLORER/RANGER companies using fiber optics and onboard power may also run the fiber optic tether down from the surface alongside the primary ROV tether. EXPLORER companies may not run copper conductors from the surface to the micro-ROV as it would violate either ELEC-003E or ELEC-NRD-001.

Companies may not pull a micro-ROV tether from surface.
Any tether management system must be on an ROV.

-----------------------

Fiber optic cabling may be coupled with other lines – rope, copper, etc. Any additional lines cannot carry data or transmit signals or electricity. Companies using additional lines should submit information on these lines, including information on how these lines do not carry data or transmit signals, with their documentation submission.

-----------------------

Micro-ROV thrusters do not need to be shrouded.
Micro-ROV thrusters must be waterproofed.

-----------------------

Companies cannot use a powered (or manual) surface winch/crane to lift the cannon (or other devices).

-----------------------

Companies may bring their own red/black tees to mark the cannon shells / non-metal debris. They must be based off a ½-inch tee and colored red or black. The station judge must be able to see and identify the object as a tee of the appropriate color.

-----------------------

MATE is not supplying power for an NRD device. Additional 12V power is allowed, but MATE is not providing an additional 12V supply. Do not plug into the 2nd point of connection into a power supply as you may overload the internal circuit.

-----------------------

Collection Baskets:
Companies may use collection baskets. Companies may put multiple items into a basket and then lift that basket to the surface.
RANGER AND EXPLORER: Companies CANNOT pull up a collection basket by hand / manually.
NAVIGATOR and SCOUT: Companies CAN pull a collection basket by hand / manually.

-----------------------

At the international competition, MATE will be providing compressed air for each station. Companies will not be allowed to bring and plug in their own compressor.

-----------------------

In 2019, the micro-ROV is the only item that qualifies as a Non-ROV device. No other mission tools may use the NRD rulings.

Some additional rulings (more may be coming). I will post a reply so readers will know another ruling has been posted.

In 2019, the micro-ROV is the only item that qualifies as a Non-ROV device. No other mission tools may use the NRD rulings.

-----------------------

Actual Cannon Dimensions:
I know a number of teams have inquired about the maximum size of the cannon that they must retrieve from the bottom. After further discussions with MATE ROV Competition officials, we decided on the following parameters for the INTERNATIONAL COMPETITION:

Length of cannon: Less than 1.5 meters.

The cannon will be constructed out of 3-inch and 2-inch pipe. This pipe may be ABS or PVC. The ends of the cannon that must be measured will have larger or smaller diameter pipe and fittings. The large end (largest diameter - 2 x R3 ) will be 18 cm or less in diameter. The smaller end (2 x R1) will have a diameter less than the large end. The bore diameter (2 x R2) must by definition be smaller than the small end.


Note: Regional competitions (especially those outside North America) may be using metric sized pipe. Contact your regional coordinators for maximum dimensions.

All lighting must be provided by non-chemical, electrical sources.

No glow sticks, etc.
