Sentry Drone

Sentry Drones are well-armed and armored security mechas. Although they have limited intelligence, they do their tasks very well. When alerted, they lock down the room they are in and then attack the intruder. Their warfare armor can scramble many types of visor signals.
Samus encounters Sentry Drones where Space Pirate operations are, mainly in the Space Pirate base in Phendrana Drifts and in the Phazon Mines. When they see her, they let out a siren and lock down the room. They will then scramble her visor and use heavy, anti-armor machine guns against her and may occasionally fire a red laser, which stuns Samus and makes her helpless for a short moment. Samus also encountered Aqua Drones designed for underwater combat, as well as a Sentry Drone equipped with invisibility in the Phazon Mines. Normal Sentry Drones can be found in these individual rooms: Plaza Walkway, Observatory Access, Research Entrance, Quarantine Access, Research Core Access, Chamber Access and Omega Research.
Sentry Drones bear resemblance to the Jolly Roger Drones later used commonly by Space Pirates in Metroid Prime 3: Corruption; however, they are tactically superior in almost every aspect.
A Sentry Drone possesses 40 HP (in Hard Mode).

;Sentry Drone
:"Sentry Drones protect Space Pirate buildings by locking intruders in corridors and then quickly exterminating them. They're extremely vulnerable to the Wave Beam, which you should always use. Once the Sentry Drone is destroyed, the doors are unlocked and you can move on. There's no way to bypass these battles, because you're locked in with the enemy."

:Found In: Phendrana Drifts, Phazon Mines
:Recommended Weapon: Wave Beam
:"Sentry Drones are the Space Pirates' electrical security guards. When you are detected by a Sentry Drone, it locks the doors around you and tries to scramble your visor. Destroy them with your Wave Beam from a distance, or you won't be able to see." 
===Metroid Prime: The Official Nintendo Player's Guide===
;SENTRY DRONE
:"Sentry Drones are flying robots that are both well-armed and well-armored. If you can surprise them with a charged Wave Beam attack, you can usually win the battle easily. If one spots you, however, it will lock down the area and attack. Use Missiles to take it out quickly."

==Trivia==
*The Sentry Drone is one of the few enemies in the Metroid series to use ballistic projectile ammunition, despite widespread use of energy-based weaponry.
*If Samus defeats a Sentry Drone with a charged Wave Beam shot or the Wavebuster, the drone will simply fall and crash instead of the usual explosion.
*Despite being a machine, a Sentry Drone is vulnerable to Power Bombs. It is possible its technology and materials are not well shielded against such a weapon.
*Curiously, the lone Sentry Drone encountered in Chamber Access does not lock the Doors of that room.
*The Sentry Drone's scan was slightly altered in Metroid Prime Remastered. The text cleans up some minor commas and grammar and changes the word "suit" to the properly termed "suite".Sentry Drones have limited intelligence, but do their assigned tasks well. Being machines, they are susceptible to electrical attacks. When alerted, Drones initiate a security lockdown, then attempt to neutralize the intruder. Their electronic warfare suit can scramble Visor technology as well. - NTSC logbook.
