Sentry bots (Fallout 4)

Sentry bots are a type of robot in Fallout 4.

Characteristics
 The sentry bot has been modified extensively and now presents a significant threat all around. While it is equipped with arm-mounted minigun and rocket launcher combination, its true asset is its protection and speed. It can rapidly maneuver across the battlefield and close distance with frightening speed to use its weapons with pin-point accuracy. It is also capable of charging at the enemy, using its sheer weight to deliver plenty of damage on contact.

Fortunately, because of its size, the Sentry Bot generates a significant amount of heat. During combat, it will occasionally enter a "cooldown" state. When it does, it temporarily shuts down and vents its fusion core. Forcing it to exert itself and exploiting these few seconds of vulnerability is key to defeating it. A couple of pulse munitions help too.

All sentry bots use a single loot list, spawning the following items: two fusion core s (always), up to three aluminum units, and two of the following: fuse, power relay coil, biometric scanner, enhanced targeting card, military-grade circuit board, and vacuum tube. There's a 50% chance that two additional items from the previous list will spawn. The Scrounger perk enables additional ammunition loot.
