The Famicom Robot and Robotic Operating Buddy were released in Japan and the U.S. in 1985 for the NES, and were compatible with just two games: Stack-Up and Gyromite. The Robot received instructions via optical flashes in the TV screen (only works when coupled with a CRT) through its eye sensors to move its arms left, right, up, down, open or closed. Both Stack-Up and Gyromite come packaged with either the Block set or Gyro set, each changing the way R.O.B. interacts with the game.
- Height: 24 cm/9.6 inches

- Arm movement range: 240° left/right (five stopping points), 7cm (2.75in) up/down (six stopping points), 7cm (2.75in) between hands when open
- Five accessory slots around the hexagonal base (numbered clockwise, starting at the rear-left; from the robot's point of view) and notches on the hands allow for specialized parts to be attached depending on the game.
- Optional tinted filter could be attached over the eyes to compensate for use with overly bright televisions.
