Robot (series)

The Robot Series is part of a series of video games released for the Nintendo Entertainment System in 1985. The series was classified by Nintendo according to their features or genre. Games in the Robot Series linked to the Robotic Operating Buddy via optical flashes of the television screen.

History
The Robot Series consists of Gyromite and Stack-Up, both released concurrently with the Nintendo Entertainment System in October 1985. A copy of Gyromite was packaged with each R.O.B. unit, including the one bundled with the NES Deluxe Set, which included other accessories and the console itself. Gyromite featured spinning tops and cooperative gameplay with R.O.B. and an optional second player. Stack-Up featured plastic blocks and foam hands for R.O.B. to grip the blocks.

Gameplay
Games in the Robot Series utilize R.O.B.'s functions to perform tasks, such as moving objects and pressing buttons. These tasks are performed by the accessory, but have significance to the game's characters. For example, when Professor Hector, the protagonist of Gyromite, is trapped behind a gate, he requires R.O.B.'s assistance to open it; this is performed by controlling R.O.B.'s arms with the control pad and placing a gyro onto the button corresponding to the color of the gate. This unique play style allows the player to experience the effects of the R.O.B. accessory's actions in game scenarios, allowing greater immersion in the outcome of the game.

In the Super Smash Bros. series
R.O.B. appears as a playable character in Super Smash Bros. Brawl.
