I just don't think that the pilots will be able to move fast enough for that to happen. I expect we'll see it once or twice but no more than that.

I do wish that the manual didn't say the GEAR sets "engage the corresponding rotor." That implies to me that the GEAR sets are physically meshed with the rotor, when the field tour explains that the GEARs drive an encoder, which tells the FMS to turn on the rotor.

Looks like we've got ourselves a steamacrit. It is odd that we don't have any written proof of how many rotations it takes, if there is a set number. Field tour makes sense, but I just can't bring myself to trust something not in the manual.

Re: Scoring of rotors

If they do not change the rules, a team could take the reserve gear and put it into the first Rotor. This would get them the 100 points but because the other alliance to also get 25 points which means that the alliance would net 75 points, which is greater than the 40 they would get if they waited for teleop.

Good point. However, if you did do this, by employing a strategy that purposefully generates a foul (repeatedly), you are going quite seriously against the spirit of FIRST.

That being said, I am almost certain that the rules intended for autonomous rotors to be 60 points total, not 60 then 40. This would make the tech foul for taking the reserve gear and powering a rotor more of a penalty than the point bonus for getting an auto rotor. (you get 20, they get 25).

I would just like to point out that there has been no rule against all three robots placing their gear on the close spring. That would make scoring three gears considerably easier and faster than having robots drive to the far side of the airship, turn, and then place their gear.

Interesting idea, although I'd definitely check the Q&A for legality.

Re: Scoring of rotors

https://firstfrc.blob.core.windows.n...amUpdate01.pdf

The team update states that rotors are scored only if they are not previously scored, so I interpret this as a rotor scored in autonomous won't be recounted for teleop.

For each ROTOR turning by period’s T=0,
that’s not previously been scored

From today's Team Update 1:

The red text is new. If it was scored in autonomous, it won't be scored again at the end of teleop. (The 4-rotor bonus, of course, still stands if you get all four turning.)
