The Nintendo R.O.B. (Robotic Operating Buddy) shipped with the Nintendo Entertainment System Deluxe Set between 1985 to 1987—and that's about all it did. The R.O.B. quickly found its way into many gamers' closets for several reasons: it came with lots of easily-lost, small parts; it required its own set of four AA batteries; it was tricky to set up properly; it only worked with two games; and it added very little to the video game experience.
