Docking with Infernal Robotics + KAS

[Tazin]

I had read it was not possible to attach docking ports to moving parts from Infernal Robotics, but today i saw the Constellation Mission video featured in the KSP facebook page. It is pretty old, from before 1.x, but there the user attaches a winch to a moving arm, and with the winch he picks up a docking port, proceeding to dock several different things with that. Is it still possible to do that?

KSP has a facebook page?

Anyways if you're talking about

then there's a part that mentions something very important:

The docking port is not actually attached to the winch, so they're two separate vessels. It should work okay as long as you don't leave physics range or warp.

This should still work, but I don't know that anyone's tested it.

I had seen something that indicated the problem was if a IR part was between the root part and the docking port. With this in mind I build a mobile gantry using a docking port to pick things up. The docking port was connected to the root and the IR parts connected the root/docking port to the body of the vehicle - been using it for a while without incident (of course now that I've said something its going to blow up).

So, whatever i build should be fine as long as the docking port connected to the IR part i actually the root of my vessel?

As I understand it - would be a good idea to do in a test game or make plenty of backups!

Just want to reiterate - After hearing this from a source of unknown credibility I tried it and, to date, haven't had problems. This being:

BAD: Root <-> IR part <-> Docking port

OK: Parts <-> IR part <-> Root <-> Docking port
