Identifying sensor strings

Post by Philbot » Mon Jun 02, 2014 8:55 am

Hi. This question is for the Explorer class.

The mission specs say we can attach the new sensor string to our ROV during the setup interval.
We are trying to decide on the best sequence for placing the new string and returning the old one.

Several question came up during our discussions...

Are we permitted to place the new sting in the designated region while the old one is still there? The rules say the mission elements can be done in any order, but other parts say that we need to recover the old one and THEN place the new one.

If they can't both co-exist in the box, can we place the new sting outside the box, remove the old one from the box, place the new one in the box, and then return the old one to the surface at a later time.

If they can co-exist in the box, will we be able to tell them apart? I can see it being confusing, and if they aren't clearly identified, both the pilot and the judges may get confused. The prop notes don't indicate two different designs/colors etc.

Thanks for your clarification.
Phil.

You may place the new sensor string in the designated square even if the old one is still in the square. However, if the two sensor strings get entangled, it will be up to the ROV to figure this out.

Good luck.

Hi

OK, that answers one of my questions regarding sequence of operation.

The other questions is one of identification.

The pilot may drop the new string into the square and then goes off to do another mission. When they return to recover the old string, will there be a way for them, and (more importantly) the judge, to know for sure which string is being returned.

eg: if the pilot returns the string they believe is the old one, but the judge feels that they are returning the new one by mistake, will there be a way to tell them apart? Clearly the team will try to identify them by where they were placed, but it would be nice to know that there is a definite way to remove any ambiguities.

Unless just bringing "either" of the the strings back to the surface is sufficient, how will the judges be instructed to tell them apart? Or, if given that they are indistinguishable, can the pilot verify with they judge at the time of capture that the correct sting has been selected?

I know this looks like a lot of questions, but it's really just one :)

Thanks
Phil.

The strings/ropes should be of a different color to differentiate new from old.

If for some reason the strings at your station are not a different color, and there is some confusion about which is the new sensor string and which is the old, and you have moved away to do other tasks in the mean time, it will not really matter which is the new and which is the old sensor string.

Good luck.
