As Seen In: Star Wars: Episode IV - A New Hope (1977)
R2-D2 may not have been able to talk, but he didn't have to. He had his sidekick C-3PO to translate all that for him. But he could do everything thing else you needed—get you out of a trapped machine, help you save your ship, or pull you out of a swamp. He's not as nimble or feature filled as other robots on this list, but he's an O.G. One that we would want by our side if we were jettisoned into a space mission. And girls love him.
