After opening ceremonies, I will answer questions about the props, etc. Also, sometime later today (Friday, June 14th) I will be publishing a TEAM BRIEFING on the international competitio...

Re: [RANGER] ROV Tool Retrieval

Yes. If debris floats within arms reach (no additional reaching tools) of a tether manager, you may remove it from the pool and not receive a penalty.

Re: [Explorer] Installation Time, PH and Cannon Measurement

1) Yes, you may attach objects to your vehicle during your five minute set up time. 2) Provided you are only pulling the independent sensor (pH sensor) out (no other items attached), yes, you can pull the wire to remove it from the water. 3) Yes. How you measure the cannon is up to you. Make sure to...

Re: [Explorer] Image Processing

1) Yes, you may measure the length of the crack without following the line. That would constitute determining the length of the crack with manual control (you are not autonomously following the line). 2) No. Once you uncover the rock, you can pilot your vehicle to get the best view of the benthic sp...

Compressed Air at the International

Hi Teams: The MATE ROV Competition will be supplying compressed air to each station for teams to use. The fittings MATE will provide are all like they find on top of a standard air-compressor - 1/4” quick-connect ‘industrial style’ (NOT ‘automotive style') female receptacles such as shown here: http...

Cannon Volume and weight in water examples

Sorry for the late date for this, but I wanted to publish some examples of cannon dimensions and provide the calculated volumes and calculated weight in water. This way you can verify your method of calculations. Once you measure the cannon in water, you will get a sheet with these dimensions for yo...

Re: [EXPLORER] Line Following

I consulted with our image recognition / autonomy folks. You may go back and retry autonomously following the line after following it manually. However, this only applies to following the line. Any determination of the length of the crack will be tied in with how you navigated the line, and cannot b...

Re: (RANGER) Lift bag (QUESTION)

Unlike 2018, your air line does not need to be incorporated into your tether. So yes, it can run independently.

Note, you cannot pull on the line to retrieve a lift bag.

Re: [EXPLORER] Air pump & Props Trial

The air hose will be the same as last year. I believe it is a standard (at least in the US) 1/4-inch connection. The hose will run to the mission station and have a 1/4-inch connector on the end. As of now, we only plan to have air hoses set up at the mission stations. We will not have an air hose t...
