''I, Robot'' is an arcade game developed by Creator/{{Atari}} and released in 1984. It was the first arcade video game to use [[UsefulNotes/PolygonalGraphics solid 3D rendered raster graphics]], and exploited it to draw its third-person views.

The player controls a robot, Unhappy Interface Robot #1984, who lives in a polygonal landscape overseen by Big Brother, an all-seeing eye. In the platforming levels, the player has to run over all of the surfaces to paint them blue (at first; see PaletteSwap), while dodging assorted obstacles. Furthermore, if Big Brother's eye is open when the player leaps, he is instantly disintegrated. The platforming stages alternate with short conventional shoot 'em up levels.

Players in a more relaxed mood can also "play" the "ungame" ''Doodle City'', which lets the player manipulate and draw 3D polygonal objects on the screen.

No relationship to the Creator/IsaacAsimov [[Literature/IRobot anthology]], [[Film/IRobot the movie]] based on it InNameOnly, nor the Music/TheAlanParsonsProject [[Music/IRobot album.]]
----

!! The game demonstrates the following tropes:

* AIIsACrapshoot: Inverted. The Unhappy Interface Robot #1984 decides to rebel against Big Brother.
* BorderPatrol: Flying saucers in space stages kill robot when it gets too far off the screen.
* BigBrotherIsWatching
* BreakingTheFourthWall: After completing the set of levels once, a new enemy is added which aims at the camera directly instead of trying to kill the Interface Robot.
* {{Cap}}:
** The player is allowed no more than four spare lives at any time.
** The score counter loops around once the score reaches 1 million.
* EveryTenThousandPoints: You'll get a new life after 20,000 points.
* EverythingTryingToKillYou: Soccer balls, sharks and birds with sunglasses are all deadly on contact.
* EyeBeams: The Big Brother's eye shoots you if he catches you mid-air.
-->'''Big Brother:''' THE LAW NO JUMPING\\
'''Unhappy Interface Robot #1984:''' OH YEAH (jumps around) WHY NOT\\
'''Big Brother:''' (opens eye, zaps the robot) THATS WHY
* FacelessEye: The eye atop of the pyramid who kills you if it catches you mid-air.
* KaizoTrap: When ending a level's space segment, you can wind up crashing head-first into the walls on the sides of the next level's docking area. Eventually the dock becomes one block in width.
* NonStandardGameOver: Eventually, you can lose all your lives while playing in Doodle City for too long, since it subtracts one life for every minute spent doodling.
* PaletteSwap: Level 27 is the same as level 1, except that instead of touching red tiles to turn them blue, you're now touching yellow tiles to turn them green. Plus of course the difficulty is increased, and there's a new enemy (see BreakingTheFourthWall above or TheFourthWallWillNotProtectYou below). There are 126 levels in total[[note]]The claim on Website/GameFAQs that there are 99 levels is probably due to the on-screen level number being 2-digit, so after Level 99 you will see "Level 0" and then "Level 1"; but the latter still has the palette of Wave 4, and it having the design of Level 23 rather than Level 1 is another indication that it's actually Level 101[[/note]], hence five waves (each with its distinctive palette) altogether (although the last wave is not complete).
* UsefulNotes/PolygonalGraphics: The UrExample (at least when it comes to raster graphics).
* RedEyesTakeWarning: The eye in levels 53-78, and again in levels 105-126.
* SawBladesOfDeath: Some platforming levels end with Robot 1984 entering a doorway. Movement forward through these segments is enforced by a saw blade that cuts away at the level, rendering backtracking impossible.
* ScoreMilking: Actively discouraged during the plaforming segments. Beating a level's best time earns an additional bonus, but only for completing it on the first attempt (without dying).
* ScoreMultiplier: Mostly to encourage players to use the camera control buttons (the two Start buttons) to change the perspective. Zooming in will cause you to score double, while zooming out will cause you to only gain half the points. Then come the Viewer Killers that directly aim at the camera and will kill the player if he/she doesn't move the Robot horizontally or adjust the camera in time.
-->"The lower you play, the higher you score."
* ShoutOut:
** Mainly to ''Literature/NineteenEightyFour'' with the number 1984, all-seeing eye and the name Big Brother.
** There is also one level with sharks and ''Film/{{Jaws}}'' theme plays.
* SinisterGeometry: Some of the hazards.
* SpellingBonus: Shooting the letters ''I, ROBOT'' (with comma) during the space levels earns an extra life.
* TechDemoGame: ''Doodle City'' seems to exist solely to show off the game's power of drawing many 3D objects on screen.
* TimedMission:
** The platforming halves of a level; allowing the Bonus Timer to reach 0 will cause the Robot to self-destruct.
** Doodle City also has a time limit which starts at one minute for each life the player has in the main game, and allowing one minute to pass will remove one life from the player's stock. Playing in Doodle City long enough to remove all the player's lives will result in an immediate Game Over, unless you have an credit instead and choose to continue in Doodle City.
* TheFourthWallWillNotProtectYou: After getting through the first loop of levels, you will meet the "Viewer Killers", which aim directly for the player's camera. Moving the Unhappy Interface Robot horizontally or using the Start buttons to change the view angle of the board is the only way they can be avoided.
