SSU V1.25 Release

[DaveS]

I have tried everything I can think to try to fix the CTD bug on my end with no luck whatsoever and now it is affecting all scenarios. So I can't test anything right now until the source of these CTDs have been found and eliminated.

I just tried the final last ditch solution: A complete re-install. This cured the CTDs.

That's great news !!

What switches/talkbacks are affected by the RMS SELECT switch? I know the shoulder brace talkback depends on the RMS SELECT position, but do the main RMS controls work only if RMS SELECT is set to PORT or will they work as long as the RMS is powered?

Looked at the PDRS checklist, and RMS SEL - OFF seems to be used for stopping a runaway arm, so it seems the RMS only works if RMS SELECT - PORT

Checked in code for the RMS SELECT switch and the RMS Shoulder brace.

OK, what's next for A8? Moving the joint angle display from a debug line to the actual displays on A8?

Does the RMS Shoulder Brace switch do anything physically other than just moving the switch?

Do we have a shoulder brace animation?

Any specifics which are still missing?

 

[DaveS]

Do we have a shoulder brace animation?

No as the shoulder brace is part of the upper boom structure of the RMS mesh.

Yes, but there is nothing visible right?

The only phenomena to tell that the shoulder brace is set is the motion of the shoulder joint should be completely impossible.

Actually it disengages from the actual yaw joint of the shoulder. See these two photos:

Yes, but as long as the shoulder pitch joint is not moved, there is no way from telling from the outside that the arm is braced.

That's what I would say.

At the moment, the shoulder brace has to be released before the RMS can be moved. I haven't updated the launch scenarios to put the shoulder brace in the engaged position yet.

Would it be possible (after release) to add another attachment point to the RMS EE to accommodate a foot retraint, so the EE can still grapple, if needed ?

Is that possible in the real shuttle?

Yes. It seems like it attaches to the RMS Side View Camera(RSC): http://spaceflight.nasa.gov/gallery/images/shuttle/sts-117/hires/iss015e12939.jpg

OK, I thought it was on the EE. Then we really need it... would it be bad to change the attachment numbers or should they remain fixed?

 

[SiameseCat]

Yes. It seems like it attaches to the RMS Side View Camera(RSC): http://spaceflight.nasa.gov/gallery/images/shuttle/sts-117/hires/iss015e12939.jpg

Would the RMS ever be used for grappling with the foot restraint attached? In the picture, it would be hard to grapple anything without clearance issues.

You are right on this one, but I think it makes the implementation easier, if we handle this special case with a special attachment.
