The name of an old European and American sci-fi movie about space

I remember that the movie was about a family who boarded a spaceship together to find a new planet for the country to migrate to. In the end, he encountered a very strange creature during the interstellar voyage. It seemed to be a creature that combined machinery and flesh, like a spider. I didn't finish watching it. There was a very classic scene in which the male lead activated his weapon system and immediately covered his face with a metal mask. After his son ran to the inner cabin, he was on a control panel. His body was immediately surrounded by a layer of light, and he could remotely control the robots outside. That was the general idea…It's very vague. I hope everyone can help me. I've been looking for it for a long time.
