R.O.B. (Robotic Operating Buddy), released in Japan as the Family Computer Robot is an accessory for the Nintendo Entertainment System (NES). It was launched in July 1985 in Japan, and October 1985 in North America. It had a short lifespan, with support for only two games which comprise the "Robot Series": Gyromite and Stack-Up. R.O.B. was released with the intention of portraying the Nintendo Entertainment System as a novel toy in order to alleviate retail fears following the North American video game crash of 1983. R.O.B. was produced in the Deluxe Set, a configuration for the console that includes, among other things, R.O.B. and Gyromite. Stack-Up was packaged separately and includes its own physical game pieces.
