Sentry-bot

Sentrybots are robots created in the same factory that Clank came from. Ratchet can use the Hologuise to get pass these robot guards on planet Quartu and Drek's fleet. If Ratchet gets caught they wiil either shoot fire balls at him or press an alarm button setting off defenses to kill him. If you wave at them in the Hologuise they will wave back and deactivate forcefields so you can get pass.
