I hope somebody can help me with this one.
Long time ago I saw a science fiction movie about a guy on a BIG spaceship, with even some eco domes attached to the ship!
As far as I remember the man was the only person on the ship (I could be wrong though) together with two maintenance robots, a bit looking like a box with two short legs and feet. The robots walked on the outside of the ship doing some welding and other maintenance stuff. In the eco domes where lots of plantes, I think the ship was some sort of space ark.
I think the movie was from the early 80's or seventies.
I don't remember the story, but I believe that the ship blew up at the end, and I think one of the little robots lost his box-body and the feet with legs stayed attached to the spacehip (magnetic I think) wich made me kinda sad at that time

That's basicly all I remember about it.
Anybody has an idea what movie this could be?
I remembered the movie a while ago but am unable to find it. Would love to see it again.
A big thanks in advance.
My best regards, Kodiak.
