Infobot

Infobots were small robots that contained various recordings or broadcasts, and contained co-ordinates to the planet of their respective origins. Their video-contents were played automatically when Ratchet or Clank approached them, on each Infobots' flat square-shaped screen which was contained inside their mouths, revealed when they expanded the distance between their metallic jaws.

Ratchet & Clank
In Ratchet & Clank, Infobots played a major part in the storyline as they helped Ratchet and Clank gain information and coordinates to other planets. After they were played, Clank stored them inside his radiator core.

Ratchet & Clank: Going Commando
Infobots were no longer used in Ratchet & Clank: Going Commando, as they were replaced with normal screens, TVs and radio transmissions. However, a Female Infobot with a love-interest in Clank makes an infrequent appearance throughout the game, even once aiding Ratchet and Clank escape the Thugs-4-Less flying prison. She was finally seen at the MegaCorp Headquarters when she tried to warn them that Qwark was posing as Mr. Fizzwidget, but she was shot by Qwark before she could finish her warning. She was later repaired by Ratchet.

Ratchet & Clank: Going Mobile
In Ratchet & Clank: Going Mobile, Infobots were used in the digital world to gain coordinates for Secret Agent Clank locations, such as Maktar Casino.

Ratchet & Clank Future: Tools of Destruction
In Ratchet & Clank Future: Tools of Destruction, Qwark gives Ratchet and Clank two Infobots throughout the course of the game that he was able to steal from Emperor Percival Tachyon. One of the two was badly damaged and could not open its mouth, and could only be played through Aphelion. These new Infobots resembled binoculars when completely inactive and they played videos by opening their mouth like a lid rather than expanding it.

Insomniac Games used these new Infobot models placed around various levels to play voice clips from Insomniac Employees, which are accessible after unlocking Tools of Production.

Ratchet & Clank Future: A Crack in Time
Infobots make no direct appearance in the game. However, cutscenes including them from Ratchet & Clank are shown on the screens in Clank's subconscious.

Ratchet & Clank: Into the Nexus
An Infobot appears only once to give Ratchet and Clank the coordinates to the Thugs arena, in a similar manner to the first game.

Ratchet & Clank (PS4)
Like the original, Infobots played a major role in the game. Ratchet & Clank would find Infobots and get coordinates to new planets.

Trivia

 * Clank flushed out his radiator core with all of the Infobots which he had gathered throughout Ratchet & Clank some time before the beginning of Ratchet & Clank: Going Commando.
