B.E.N. (aka Bio Electronic Navigator) is an abandoned robot on Treasure Planet in the Disney movie of the same name. B.E.N. is a bit off because part of his cognitive computer has been removed. This prevents him from knowing some vital information. Information like removing the treasure will cause the planet to explode. Luckily, they find his missing computer BEFORE they remove the treasure. What a lucky break.
