Setup
- Insert Batteries: Open the battery compartment on the back of the R.O.B. unit. Insert four (4) AA batteries, ensuring correct polarity. Close the compartment securely.

- Prepare Accessories (if applicable): For games like Gyromite, place the Gyros in R.O.B.'s hands. For Stack-Up, arrange the colored blocks and Spinners as instructed by the game.

- Start a Compatible Game: Insert a R.O.B.-compatible game cartridge (e.g., Gyromite or Stack-Up) into your NES console and power on the NES.
- Game Interaction: Follow the on-screen instructions within the game. The game will display specific light patterns on the TV screen that R.O.B. will detect.
- R.O.B.'s Actions: Based on the light patterns, R.O.B. will perform actions such as:
- Rotating its base left or right.
- Moving its arms up or down.
- Opening or closing its grippers.
- Player Input: In games like Gyromite, you will control a character while R.O.B. manipulates physical objects (Gyros) to open and close gates. In Stack-Up, you instruct R.O.B. to stack colored blocks according to patterns displayed on screen.
- Power Off: When finished, power off R.O.B. by pressing its power button. Remove batteries if R.O.B. will not be used for an extended period.
Maintenance
