I remember seeing a sci fi movie in the 80s. It was set on a space station. One of the main characters was a levitating squat droid with spheres for feet (which probably powered his levitation), and he was about the size of 2 basket balls. He had cute eyes (white squares with black pupils).
There was an enemy droid. It was much larger, and maroon in colour, with menacing eyes.
Unfortunately I can't remember much more than this.
Can you recall what the name of this movie is?
