I remember I was watching the movie around 10 (?) years ago. It's probably a US movie (or UK or Australian) – I mean, not the Indian one or whatever.
The storyline is really close to the one Saturn 3 has. But I have looked thru some screenshots of that movie and finally decided that it's not that one – the special effects in the movie I'm looking for were much better and I think it was actually produced in between 1990–2000, not in 1980.
Don't remember all the storyline details, but it's something like that:
A crew of a spaceship meets another spaceship which looks abandoned.
The crew gets into the second spaceship to find out what happened there.
Something starts killing the crew, one by one. It was quite scary – one of them was hanged down on a chain, how other died I don't remember.
Finally the crew (those who stayed alive) finds out it was a mad (?) robot on the second ship who killed the original crew.
Another scene – closer to the end of the film – is when the members of the crew were standing silently in front of the robot, he was analyzing the situation trying to understand if there were some people here. The idea is that the robot's intellect is poor and he recognizes humans only when they move. So it was a situation when each member of the crew was really nervous and was thinking about trying to run away or staying calm and don't move at all.
Thanks for any suggestion!
