Update #9

I don't think it will matter. Not much action will take place during the .04 seconds that things will be in the disabled state. Even balls in the air won't move much during that time slice. The processor might be able to add a few integers or a real number or two during those 40 miliseconds, but not much else.

It is a negligible delay (I wrote the Q&A question, I agree). However it doesn't transition seamlessly because it enters a disabled state (Answer suggests it does not enter a disable state). As a followup, They should just post the bullet list or see Update 9 so no one gets confused. Jared brings up a good point with the single solenoids and disabled. It is also more complicated to carry over program state from autonomous to teleop (and simulate that transition in the lab, my fingers arent that quick )

I'm not finding drawing GE-0940 Rev B. The update says it's in Section 8, but I don't see it there. Nor is it with the Game specific drawings in Section 6.

Am I misguided, or what?

I can't find it either. The Game specific drawings have GE-0940 Rev A, but there is only the original trailer hitch diagram in it. I guess they must not have posted it yet or have hidden it with great skill.

Mods, should this thread be merged with the other update 9 thread? http://www.chiefdelphi.com/forums/sh...686#post813686

Good, other people are having trouble finding the new drawings for the trailer hitch. I thought I was just web site incompetent.

Has anyone asked Q&A about it?

[Jared Russell]

The presence of a disabled state between autonomous mode and teleop can have an effect on teams using single-acting pneumatic solenoid valves...

The new drawing has been posted at the end of Section 8 on the 2009 FIRST Competition Manual and Related Documents page.

Looks like a shorter (3") length of Andy-Mark chassis material (C-channel) is allowed for the trailer mount bar. Presumably this avoid interference of the mount with the hitch tongue given the larger (3/8") clearance hole in the hitch swivel.
