What part allows for motorized hinges, etc?

[Major SNAFU]

Hi all,

I doubt I have posted this it the correct place, so please relocate it as necessary.

What I want to know is what part, or what mod has parts, that allow you to build ships and rovers with girders, etc that can fold and unfold (similar to the landing legs)?

I have seen a number of videos where people have used docking ports as clamps on the ends of beams, etc and I want to try my hand at some of these designs. The key is that the end of the beam opposite the docking port is attached to a part that swings the beam in an arc. That is the functionality that I am looking to implement.

Thanks in advance,

SNAFU

Your looking for Infernal Robotics.

No stock parts do this, so your question has been moved to the modding section.
