Junkbot

Junkbots are robots encountered in the Commonwealth in 2287.

Variants
The Mechanist's automatrons are cobbled together from a wide variety of components 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 hands.

Servomech junkbot
The Servomech variant shares the same looks as the basic Junkbot but this variant is stronger and more rare to encounter.

Integrated junkbot
The Integrated Junkbot uses two arm-mounted weapons, the left arm has a laser rifle mounted to it and on the left a portable canon. This variants is also more rare to encounter.

Cybermech junkbot
The Cybermech variant is a very rare encountered Junkbot and only first spawns when the player has reached beyond level 40. This Junkbot has one Gamma gun mounted to each arm and are 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 rarest Junkbot that can be encountered and only spawn when the player has reached beyond level 50. Even then this variant is very rare to spawn. The Quantum variants has one laser rifle mounted on each arm and the body of the Junkbot is surrounded by an electric field covering the crusial 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.
