The Mister Handy series of robots, named so because of the robot's large number of hands, was first brought to market in 2037 as a general construction and maintenance unit by General Atomics International. Primarily used in the United States and Mexico (where it was the leader in sales after the Mexico City earthquake of 2042), the Mister Handy was a reliable robot. An early bug that caused interference in the operation of the multiple arms was fixed with a hardware update in 2039, with no major problems since then. A key selling feature is the nuclear power unit (a model 238B, licensed from Calpower) and self-maintenance modes. Multiple Mister Handies are capable of keeping themselves in working condition (Self Diagnostics) and are also fully programmed to perform nuclear fuel replacements. Secondary programming handles radiation cleansing after refueling.
This particular model of Mister Handy, also seen in Fallout 4, has a chromed coating instead of having a more common white coloration as seen in previous iterations of Fallout. It also appears to have the more human sounding voice module from Fallout 3, rather than the more robotic voice from Fallout: New Vegas.
Limbs and other parts of the Mister Handies will fall/break off when they take damage. This can reveal concealed parts in addition to making them virtually useless. Mister Handies and their other fellow robot brethren have three different weapons; two of them being ranged and the other a melee. It is possible to shoot the equipped weapon off and force them to switch weapons if one is using V.A.T.S.
A Mister Messenger is typically a darker color than standard, silver, Mister Handy units. They are almost exclusively found during an event to deliver a message to a specific location. The player characters accompanying the Messenger must protect it until it arrives at its destination.

The Mister Farmhands are more or less, a standard Mister Handy model with a pale green paint job. They are typically encountered on the roads from Vault 76, to Flatwoods, among other various areas in the Forest region. They can also be found, as their names might suggest, at a few local farms, and if participating in a successful farm event, Mister Farmhands will come to the aid of the player character.
A robot encountered through a few random encounters involving the player character winning the Appalachia Sweepstakes. He rewards the player character with different items depending on the area he's encountered, either Cram or bottlecaps in starting regions, or stacks of 100 pre-War money, or similarly valuable items like silver pocket watches around the more wealthy Cranberry Bog, notably on the outskirts of Watoga.
