Junkbot

Junkbots are robots encountered in the Commonwealth in 2287.

Variants
The Mechanist's automatrons are cobbled together from a wide variety of components and junk taken from five different robot models. Junkbots are perhaps the most consistent type in terms of component makeup - usually they are little more than a basic protectron without any exterior armor and therefore easy to destroy.

Junkbot
The basic variant of the junkbot is the weakest of the junkbots and never have any melee or ballistic assorted weapons, but only uses its robot hands.

Servomech junkbot
The servomech variant shares the same looks as the basic junkbot, but this variant is stronger and less common.

Integrated junkbot
The integrated junkbot uses two arm-mounted weapons: a laser rifle on the left arm, a portable cannon on the right. Spawns less frequently than its weaker variants.

Cybermech junkbot
The cybermech variant is a rarely encountered junkbot and spawns once the player reaches level 40. This junkbot has one gamma gun mounted to each arm, used to eliminate enemies from a further distance. As for the body, the head is the one from a tankbot and the junk attached to its shell is painted yellow.

Quantum junkbot
The Quantum junkbot is the strongest and least common junkbot that can be encountered and only spawns when the player has reached level 50. Even then this variant does not appear often. The Quantum variant has one laser rifle mounted on each arm and the body of the junkbot is surrounded by an electric field covering the crucial parts of the robot. Like the cybermech variant the body consists of various junk pieces painted yellow.

Appearances
Junkbots appear only in the Fallout 4 add-on Automatron.
