Sentry Bot (Fallout 4)

A sentry bot is a type of robot in the Commonwealth in Fallout 4.

Characteristics
The weapons of the sentry bot remains the same as seen in Fallout: New Vegas, with a missile launcher and minigun, however some can be seen with dual miniguns instead. Although at least some variants appear to have four legs instead of three as seen in the previous versions.

Gameplay attributes
Sentry bots are some of the rarest and the most difficult robots to defeat - fast, agile, heavily armed and resilient enough to absorb a direct hit from a Mini nuke. After losing both main weapons they initialize their self-destruction and charge at the player character. Even with their ranged weaponry intact, Sentry bots often charge into close combat to deliver powerful blows with their arms if one ventures too close, thus deterring attackers from any use of melee weapons. Since they explode on death with the force of a mini nuke, this tactic may prove even more dangerous to their opponent than their devastating long-range firepower.

Sentry bots are a good source of fusion cores, dropping at least two when they are destroyed, along with other valuable electronic components.

Low level players can defeat a sentry bot with hiding and running away until the sentry bot takes a few seconds to cool off revealing his weak fusion cores in its back. Firing any shot at them will instantly kill the sentry bot, however, the cool-down lasts only 2-3 seconds so one must act quickly, even after destroying a sentry bots fusion cores, it will still drop at least 2 fusion cores.

Controllable sentry bot
An inactive Combat sentry prototype MKIV can be found at the Robotics Disposal Ground. Inside the shed near the entrance to the facility there is a terminal that has a holotape loaded. Initiating the holotape on the terminal activates the sentry bot outside, after which it immediately starts to patrol the area. By ejecting the holotape from the terminal and using it in the player character's Pip-Boy the Sole Survivor can command the sentry bot to different locations in the Commonweatlh.

Bugs

 * At Robotics Disposal Ground, the prototype sentry bot MKIV does not move once powered on.
 * Fast travelling elsewhere and sleeping can fix the problem. This is confirmed to work.
 * Using the Robotics Expert perk to disable and then re-activate the sentry bot can also fix the problem.
 * The bot will occasionally disappear when it is in patrol mode.

Locations
A sentry bot will attack the Sole Survivor after exiting the national guard armory.
