Sentry-bot

Sentry-bots were the robots created in the same factory that Clank came from. Clank was actually a malfunctioned Sentry-bot. Ratchet could use the Hologuise to get pass these robot guards on planet Quartu and Drek's Fleet. If Ratchet was not wearing his Hologuise, they would either shoot fire balls at him or press an alarm button to activate fort defenses. If Ratchet waved at them while using the Hologuise, they would wave back and deactivate forcefields so he could pass.In Ratchet and Clank Future:A Crack in Time one of them appeared on some of the screens in Clank's subconscious.
