What is this movie called?

I saw a movie a few years ago on cable. It was a sci-fi made in the 60’s or 70’s. I was about a crew sent to check on a scientist that has disappeared. They found him, but he was the only one onboard the spaceship and everyone else were robots. He was directing the ship towards a black hole because he thought that something incredible would happen. It had a robot, a woman, and 2 or 3 guys on the rescue crew. The robot had a twin on the spaceship, but he was all beat up. It felt like a cult film to me. What is the fraggin’ name of the movie I watched?
