UniversalCargoDeck & Atlantis

[Whatu]

Im trying to load two different things in the default Atlantis, a Destiny module (by No Matter), and a PMA (by Well).
I put them in separates bays in the UCD, and adjust placement so they fit nicely.
Now the problem is, when Atlantis gets to orbit, it behaves like the payload weights a lot. Rotating is very difficult.

Is there any way to avoid UCD passing the mass of payloads to the core vessel?


On a side note, I noticed that when using Universal Remote Manipulator System with Atlantis, at the moment of SRB jettison and Main Tank, the Center of Gravity changes and so does the Arm, but this can be worked around placing the arm after reaching orbit.

Thanks in advance!

May be something wrong with calculating of summary PMI of Atlantis and payloads... I will check it.

Yes, I wrote about this problem in manual. Sadly I can't resolve it. It is principal incompatibility with vessels which changes place of COG itself.

Thanks for taking a look at this

Also the URMS thing is not that important, because it can't be done better, and it is not seen until srbs and tank have been jettisoned.

Your addons are great Kulch, ! many thanks.

...URMS thing is not that important, because it can't be done better...

It CAN be done better and it will be better! I'll release the second version soon.

Well I know very little about coding, but URMS being able to be attached to anything and grab anything looked like a very hard work (to me). It also has many features and such...
But if you say you can make it better, I guess you are right (and I'm happy :speakcool

huh... to me - to
but - very interesting!

just two new options:
- inverse kinematic control mode
- automatic 'grab closest object' option
(but tssss.... it's a secret :blink

This may sound stupid but what is inverse kinematics ?

 

[Coolhand]

it basically means that you move the 'end effector' (your hand is the end effector of your arm for example) and the rest of the mechanism automatically moves to put the end effector where you want it. It's the opposite of forward kinematics where you'd move the components of the arm to put the end effector where you want it.

Inverse can be more intuative and faster since its more like how the body works, if you want to pick something up you just move your hand, you don't think 'rotate upper arm 30 degrees on shoulder x axis, 20 on y axis, rotate wrist 10 degrees, etc' until your hand meets the target.

Sounds great Kulch !!

@ Coolhand
Thanks For explaining

Just to let you know, this seems to happen with any vessel. I recently attached a bunch of crap to the Shuttle A, and it was nearly impossible to fly due to the "slow rotating" thing.


P.S. I am looking foreward to an I.K. URMS. You've made some amazingly useful stuff (Cargo Deck and URMS). Keep up the good work!

The bug is found now. I will release new version of PM and UCD soon.

Glad to hear this

 

[kulch]

Ok, new versions of PM and UCD relesed now.

UCD is now based on Payload Manager 2.2.3.0 and compatible with vessels which can shift it's COG and change it's dry mass (like Atlantis or any CVEL-based vessels).

In PM was fixed bug with incorrect PMI calculation.
