Gif is non-looping, F5 for reset.
Gif is 12mb. (still figuring it out, next one probably smaller

ok, here is a gif I made

I got a bit side tracked, but I think it's ok (even necessary maybe) because i'm learning stuff that i can use for other stuff.

I'm now going to try make the unit flip around 180 degrees when it stops to load the 'passenger', which I suspect will look a bit weird. (maybe I can think of something for that)
But first I'll try to make the loading-arms look a bit more sensible
